    I hope your parents are doing better.  I noticed you are applying filler over epoxy.  Which is better -filler applied over bare metal vs painted metal?

     

    Thanks, mom is almost back to normal and dad still has a cough but the other symptoms have cleared up.   

     

    I always shoot two coats first to seal the bare metal 100%.  If the paint was ever damaged to the point that the filler becomes exposed there is still epoxy under the filler to protect the metal in case the damaged filler gets wet (filler is porous and will absorb water).  Another reason to do epoxy first- epoxy sticks to bare metal really well.  Filler likes a rough surface to stick too, and I would rather not grind the metal that hard (36-40 grit is often used) to roughen it appropriately.  I use SPI epoxy and it has a seven day window to top coat it with filler or other primers and they'll chemically bond with the epoxy with no sanding needed within the seven day recoat window.  The pretty much guarantees 100% adhesion of the filler to the epoxy, or adhesion of the high build primer as long as you don't go over the epoxy too soon before it has started to cure enough- I like to wait at least 24 hours for filler or 4-5 days before high build primer.  I always seal the filler with two more coats of epoxy before moving on to high build primer.  

  2. The firewall to kick panel flange was really wavy around the spot welds so that was straightened, then I ground back the edges until the height of all the layers matched.  (I thought more of this was visible, but it's mostly hidden under the inner fenders after test fitting them.)

    The flange of the cowl skin was wrinkled and uneven so I trimmed both sides before final blasting.

    With those spots finished up I rolled it out and blasted the inner layers of the cowl sides that were cut open, and I lightly blasted over the floor, firewall inside and out to prep for two coats of epoxy.

    I started bodyworking the firewall by skimming the upper face and flange.

    Once both sides were filled/blocked into the correct shape and straight I masked off the inside corner and used a spreader with the corner rounded off to make an even radius from side to side.

    Another coat of epoxy to seal the filler and extend the 7 day recoat window.  Both mom and dad have had covid for the last 2.5 weeks so I wasn't able to get much done within the first 7 day window.  They're both doing much better now and things should be back to normal soon.

  3. I pulled the column to finish up the filler panels. 

     

    qzVw0wBh.jpg

     


    While the pedal assembly was out I found a spot to mount the clutch safety switch.  Had to carve out a spot for the stem to make enough clearance, so I used a 1/2" round carbide burr to make the face of the cut concave, that way  the convex face of the stem will always center itself on the pedal arm.

    Forgot to take pics, but I chopped the clutch pedal pad off and raised it up to match the height of the brake pedal pad.  Also slightly tweaked the brake pedal pad to get it inline with the clutch pad.  

    K80RuE4h.jpg

     


    I ordered cowl bottoms a few weeks ago but UPS sent an email about the address being wrong, so delivery was delayed until last week.  They're very nicely made, probably the best fitting patch panels I've used.

    Trimmed, shipping primer stripped, two coats of epoxy applied, and welded on.

    The cavity is accessible so I brushed on a couple of coats over the welds and soaked the seams to let epoxy wick in and seal up the spot welds.  

     

    Og5rmNch.jpg

     


    I made a panel to mount the fuse box so there would be no fasteners through the firewall.

    Also deleted the original pressed-in wiper motor mounting boss- welded up the holes and welded a nut between a couple of fender washers to make a new mounting pad for the wiper motor.  The accelerator pedal mount got welded in permanently after confirming that the location fits the owner.

  4. When I was blasting a pinhole opened up on one of the cowl boxes, so I stuck my phone in the cavity to see what it looked like from the inside.  There was some scabby dark patches that indicated deeper pitting so I went ahead and cut both sides open.

    Patterns made and transferred to 18g. 

     

    oiZw31ah.jpg

     

    I used the vice, a delrin block to back it, and a rounded over chisel to form the drains. 

     

    ZjKv4LGh.jpg

     


    Forming the drains shortened the flange from the steps added so it made the panel curve.  Before and after stretching to make it flat again.  I also added an extra drain to help prevent water building up in the future.

    While i was working around the cowl area I made a template of the vent openings so I could make block off plates. 

     

    sSJzKx5h.jpg

     


    The owner requested that I "clean up" the transition between the bottom of the dash and the column. The lower flange was oddly shaped and had a really oversize cut out to mount the column.  The new mount on the Ididit column was taller than it needed to be so there was a large gap between the column and face of the dash.

    The tabs of the mounting bracket hung down pretty far, making them visible. 

     

    fq9FVNph.jpg

     


    I taped steel wire to the wiring harness so I could pull it back out of the way of the bracket area, then cut the bracket off and shortened it.

    TleQDluh.jpg

     


    Column back in place, bracket tabs no longer show. 

     

    GBBcYRkh.jpg

     


    I made a couple of filler plates to finish out the opening between the column and lower dash flange.

  5. The owner decided to do away with the stock column and column mount and use an Ididit column instead.  I cut out the original opening and welded in a smooth panel to prep it for the new mount.  

    3JZnQebh.jpg

     


    I made a doubler panel for the clutch M/C to sandwich to stiffen the firewall and prevent flexing from the added pressure.  I just freehanded the beads so it's not the best looking but it's functional.  The Pullmax came with beading dies but they wouldn't work to make intersecting beads without flatting the first bead at the intersection point.  I carved out a new lower die to match the original, but with a relief to clear the first bead.

    Welded up some random holes, and smoothed/straightened the 90* edge across the firewall.

    The clutch switch needed a mount, so I used 16g with slots cut for it to clip into. 

     

    VrwUjP5h.jpg

     


    16g wasn't quite thick enough for it to clip in tightly, so I dimpled the slots to tighten the fit. There are curled plastic tabs to tension the tabs against the slots.

  6. And the fun stuff...  the owner brought the hydraulic clutch master cylinder setup from Modern Driveline and the pedal assembly to the shop today.  The pics in the instructions didn't look anything like the '66 firewall and the box was marked 61-66 so I looked up pics of '61-'64 firewalls, knowing that they were different.  Seems like the kit was designed for the different 61-64 firewall and pedal assembly.  

     

    Instruction pic-

     

    3r7lX95h.jpg

     


    Wider 61-64 pedal mount with straight pedals.  65/66 have curved pedals and a narrower pedal assembly mounting pad. 

    iEerOfVh.jpg

     


    This vid shows the problem with mounting the kit to 65/66 pedals and firewall. 

     

    https://www.youtube.com/watch?v=qeIGHAxHDiY

     


    This was the starting point of the clutch pedal, it was pretty crooked and the pedal pad plate was welded on too low compared to the brake pedal pad. 

    GY2YxTnh.jpg

     


    A 24" adjustable wrench and the vise worked to easily straighten the kinks out.  I still need to relocate the pedal pad.

     

    HKLE2qRh.jpg

     

    CpH3mjFh.jpg

     


    The instructions didn't say how far away from the pedal pivot point the pushrod mount needed to be for the correct throw, so I had to measure the master cylinder travel (~2 3/16")... 

     

    WVCX01Fh.jpg

     

    wAIOIPVh.jpg

     


    Then I set the pedal up with a stack of shims at the floor to replicate padding and carpet, and I added a 1/16" shim on top of the old top stop to simulate a taller new bumper since the old one was flattened out a bit.  

     

    nuRGumEh.jpg

     


    That set the maximum travel of the pedal.  I found the point that had 2 3/16" travel and marked it- about 6 1/8" away from the pedal pivot.  

     

    qn2pOlNh.jpg

     


    The mount area needed to be spaced over so I made a pattern and made a 3/16" thick strap to weld in place.

    Firewall drilled to mount the master cylinder and linkage.  In the instructions and video it shows the m/c being mounted at an angle which looked wrong, and the linkage hanging downward so it was more visible under the dash.  I drilled the m/c holes vertical instead and installed the linkage upside down to hide it better.  The offset bolt pattern kicked the linkage closer to the pedal assembly this way for less angle on the heim linkage. 

     

    AEDrdqHh.jpg

    Linkage adjusted, checking linkage angles with the pedal in and out.

  7. Boring stuff first- I mounted the cab on the rotisserie so I could scrape off the undercoating and grind the tunnel welds to prep for blasting.  I planished the worst spots along the weld seams to roughly even out the shape, at least the ones I could reach through the shifter opening.  

     

    7tkR39kh.jpg

     

    2qEvEUwh.jpg

     


    Never ending stream of dust and dirt. 

     

    TLp6r3fh.jpg

     


    There were quite a few really sharp spot weld blow-outs that I smoothed out with the 2" grinder.  

     

    cnwdcteh.jpg

     


    Ready for blasting. 

     

    sLiJ937h.jpg

     


    I noticed a few small pin holes in the bottom edges of the cowl sides so I cut both out so I could clean up the inner panel with the blaster.  These are reproduced now so I'll get a set ordered in the morning. 

     

    DIc7P3gh.jpg

     

    hdBBG2ih.jpg

     


    Random small holes welded and smoothed. The factory punched drain holes in some of the beads so I welded those up too.

  8. There was a indention stamped into the passenger side of the original tunnel that needed to be flattened before I could start fitting the new tunnel. 

     

    acs0siYh.jpg

     


    After using a hammer and dolly to flatten the indention.  The flange needed shrinking since stamping the indentation stretched the metal. 

     

    ZFBU492h.jpg

     


    Using a tuck tool to form a tuck, then hammering the tuck flat to shrink the high area. 

     

    BuxgOPWh.jpg

     

    ZPojRqwh.jpg

     


    The top of the tuck is hammered in first to lock in the tuck, then the rest is hammered flat which shrinks the area.  This is after one tuck.  

     

    GaDPSpTh.jpg

     

    CpAss9hh.jpg

     


    A second tuck got the flange straightened out. This view also shows the rear rounded corners of the tunnel that were later cut out and reshaped to fit the raised tunnel. 

     

    nTPRB2kh.jpg

     


    A few vids on tuck shrinking.

    https://www.youtube.com/watch?v=XI-7lyaoiz4

     


    With the flange straight I trimmed both the cab floor and new tunnel so the tunnel slightly overlapped the floor, then used a scribe to mark the trim line.  The shape of the new tunnel and the floor was still slightly different, I'm guessing from stress in the original floor from the stamping process.  I tacked the places that did fit up, then marked out a grid inside and out so dad could hold the dolly on one side while I hammered the other side to bring the panels into better alignment.  I had to do a bit of heat shrinking to bring a couple of areas back into shape.  

    I forgot to take pics, but the back rounded corners were cut out, reshaped with the shrinker/stretcher and a section of round tube in the vise as a dolly, then tacked back in with the front edge about 1.25" higher than the factory position, so I had to make a triangle shaped filler strip under the rear corners.

    Before pics of the stock tunnel. The new tunnel retains the same basic shape, bead detail, and offset at the front driver side for more throttle pedal clearance.

    The fuel line hole isn't needed anymore, so I cut a plug and welded it closed. The owner will be bringing the clutch pedal setup soon for me to mock up.  I'll work on blasting the cab and get started bodyworking the roof and rear of the cab until then.

  9. I didn't buy a car new enough to have fuel injection until I bought the Conquest 6-7 years ago, and I still prefer carb'd cars. 

     

    My daily is an '89 Festiva that has Yamaha RX1 sidedraft carbs, I have an '88 Festiva with a Miata 1.6 swapped in that has dual sidedraft Dellortos in place of the factory efi, I have my granddad's '64 C10 that has a two barrel, my '64 VW had dual downdraft Dellorto carbs, and most of my past daily drivers have had carbs...  but none of my friends know anything about carbs.

    I'm OK with some of their thinking. Just because a car is 20 years old doesn't mean it should automatically qualify for any special classic consideration (we're talking 2001 model year here). 

    Heck, as far as I'm concerned nothing from the 1980's or newer should qualify as anything but "used cars".

    Nothing is more incongruous in a field of 1920's  to 50's (even 60's) cars as someone's 1992 Plymouth Sebring parked there like a usurper pretending nobody notices it's completely misplaced.

     

    Us 20-35 year old guys grew up wanting the cool new 80's/90's cars as kids, and now 15-20 years later we're buying them and showing them now that we have more disposable income.  I was born in 1987 and wanted a Mitsubishi Starion/Chrysler Conquest as a kid after seeing a neighbor's red widebody '88 Conquest TSi.  I finally found and bought one about six years ago. I got dirty looks from old guys when I took it to local car shows (with no cut-off date) and it was even questioned "is this allowed in" as they waved in brand new Corvettes (unquestioned of course, because Corvette). 

     

    It's exactly the same as the baby boomer generation buying what they thought was cool as a kid, or buying and showing the cars they had back in high school.  My dad is 69 years old and has owned his own classic car related buisiness since the mid 70's.  He's just new "getting" the collectibility of 80's/90's cars.  

     

    Kicking out newer collectible cars will only kill the clubs associated with the shows that want to limit attendance to pre-80's.  Younger car enthusiasts (as a whole) don't care anything about cars old enough to have a carburetor.  Excluding them from bringing their 80's/90's car will only further divide the hobby and lessen interest in older cars.   I get the sentiment; I'm 33 and don't care anything about cars newer than the mid 90's myself, but I also get why they shouldn't be excluded from a general car show *if* you want the club that is hosting the show to survive well into the future.   A rolling cut off date fixes the issue of someone bringing cars straight off the showroom floor to a "classic car show" while allowing the younger guys entrance with the cars they grew up with. 

     

    A cut off of '80 and earlier would alienate a very large group of enthusiast and ensure a steady decline in club members.  Look at the very rapid growth of Radwood and their events; they cater only to 80's and 90's cars.  Maybe they've become so popular since traditional shows frown at more modern cars?

  11. I needed to make a hole in the tunnel for the shifter, but the shifter was too close to the seat as it was.  

     

    3ZjV6Kgh.jpg

     

    MaHUo0uh.jpg

     


    Shifter assembly flipped around for more seat clearance, e-brake mounted to the tunnel, and shifter hole punched in the tunnel for a test fit.  I positioned the e-brake lever so that the both boot bezels will line up evenly at the front.  With the trans in first gear there will be room between the shifter and seat to easily reach the e-brake handle.

    The gas pedal is drive by wire and needed to be mounted.  The spring tension is fairly high so I made a 16g plate to spread out the load on the firewall.  This will also let me clamp the pedal in a few different locations and pick the one that feels the best before permanently mounting it.  I'll measure the brake pedal location in the donor truck and mount the gas pedal in a spot that makes heel/toe downshifting possible.

    While the weather was too wet for blasting, I started planning for the upholstery.  The tank is under the bed now so the back of the cab will have an upholstered panel.  I made a 16g flange for the lower edge of the panel to clip into, then roughed out paper patterns of the panels and clip locations. These are things that are better to do before paint. 

    ZsN0rgLh.jpg

    The headliner will be fabricated from aluminum panels so I patterned b-pillar covers as well.  We have the donor roof's inner structure to make the headliner pattern from.

    I was hoping to have all of the cab blasted by now, but the weather has been wet on and off for the last week. But, contrary to the usual "blast with one hand, prime with the other" mindset, I like letting it sit in bare metal for awhile after blasting. This shows all of the places that weren't blasted well enough- humidity causes any rust that's deep in a pitted spot that wasn't cleaned out 100% to start growing again.  These are areas that were pitted, and rust deep in the pits wasn't fully blasted to clean gray metal.  It's not hard to overlook extremely tiny specs like this while you're blasting between the amount of area you're trying to cover and the lens of the blasting hood getting dusty.  Letting it sit until missed areas pop back out then going back with the blaster to target those areas is a good way to make sure every square inch and every tiny rust pit is 100% rust free before the epoxy goes on.  These spots were invisible immediately after blasting and only showed up days later.

  12. The original hand brake was deleted since it would be in the way of the clutch master cylinder for the T56.  The owner decided on a tunnel mounted e-brake instead.  I made a backing plate out of 16g on the Pullmax to add some strength to the top of the tunnel since the mounting area will see some strain when the brakes are applied. 

     

    X2sX365h.jpg

     


    Mounting the handle as intended left very little room for your hand to get between the floor and handle- even less once padding and carpet is added.  

     

    E3IdcfFh.jpg

     

    WrOuZ7Jh.jpg

     

     

    Part of that problem was a gap between the last tooth of the ratchet section and the base where the release lever rests, so the handle could droop with a bit of free play between the base and the first notch.

     

    BNeaiDGh.jpg

     

    u1vqh22h.jpg

     


    I welded up the base to take up the free space so the lever can't tilt down past the first tooth. 

     

    XYBDSoFh.jpg

     


    I also flipped the front mounting pads to the top of the panel to angle the handle up slightly more.

    With the mounting pads flipped the bolt heads were sticking up too far to be covered over with carpet padding, so I welded the bolts into the brackets upside down to work as studs, then cut the bolt heads off. I also shaved down the rear bolt heads so they'd have a lower profile.  Compare the gap between the boot bezel and the floor in the last pic to the one I posted above.

    I appreciate the comments!  

     

     

    I started blasting the cab and the passenger floor had pretty deep pits.  I remembered the other F100 having rust in the seams between the floors and cab mounts so I decided to go ahead and cut both floor pans out to avoid future problems.

    Fabbed a new passenger side patch.  This has a bit of a reverse curve in it so I used the linear stretch die in the planishing hammer to create the drop off while keeping the upper half completely flat. 

     

    tVsppXqh.jpg

     


    More of the driver side was pitted so I bought a new pan for that side.  It fit pretty well after a little trimming.

    The owner had cut the top of the tunnel out to fit the T56, so I made a new taller tunnel.   I used the Pullmax to add an original style bead around the top perimeter, bent the edges over, then used the linear stretch die to curve the front up.  I made a template with the shrinker as a guide for shaping the curve.

  14. The rear of the door jambs had a couple layers that stuck out for a tab to hold the inner and outer panels together.  This looked pretty terrible, and even with the planned carpet and inner panels there would be no way to make this area look neatly finished.

    Test fitting the area with a carpet scrap and panel board... it still looks unfinished.

    Flange cut flush with the jamb edge.  This left a recess that needed filling in.

    Thanks Gary! 

     

     

    I had stripped the doors awhile back by blasting the inner frame and DA sanding the outer skin, but there were rust specs that didn't sand off.  I didn't want to blast these and warp the skin so I used Ospho to soak the spots, along with scrubbing with a scuff pad and a stainless brush on the worst spots.  Most came off quickly but a few spots took awhile to clear up between scrubbing and soaking.  I kept the Ospho wet and thoroughly rinsed the doors to neutralize the acid so there would be no issues with epoxy adhesion.

    Starting to clear up.

     

    xhBvvn4h.jpg

     

    vY4iVECh.jpg

     


    99% clear, one spot was more stubborn.  Blasting the door would've meant spending more time on this spot with the blaster, so the metal would've stretched more in this spot than anywhere else, leaving a high spot.  Acid with epoxy isn't ideal but I felt better about doing it this way to prevent warping. This is another reason I don't trust "rust converters" or Por15 type products... even with abrading the surface to bare metal all over there were deep enough pits that a spray on rust converter wouldn't have been able to penetrate into fully to kill the rust at the base where it's most active. 

     

    ZOQ4EG3h.jpg

     


    I found a spot of rust through where a brace is spot welded to the frame, so I cut it out and blasted the inside the inner frame.  There was a bit of flash rust from rinsing the Ospho off that needed to be blasted off the inner frame too. 

    8QNX0Gch.jpg

     


    After light blasting I welded in a patch, then brushed on two coats of epoxy to seal up the inner frame and bracing.

  16. The last time the owner visited he brought a set of reproduction knobs and bezels for me to graft onto the Vintage Air switches.  

     

    bPxnvaxh.jpg

     


    The switches have M7-.75 threads and the original retaining nuts had a small enough ID that they could be drilled/tapped to match.  The shaft of the switch is 15/64ths, and the new knob's ID were smaller with enough material so they could be drilled out to match.

    The original switch holes were dimpled to clear the bulge on the back of the bezel.  The new holes I made earlier weren't, so I had to add those. 

     

    OHG1ACLh.jpg

     

    coBles7h.jpg

     


    I used a large washer for the OD of the dimple, and marked the center of it with making tape to center it behind the switch hole. This was clamped in place with a plate behind it to set the depth of the dimple. 

     

    wpbZLwqh.jpg

     

    glOn8LUh.jpg

     


    Another piece of tape with a center hole was marked to locate a 1/2" socket.  I used a large C clamp to press the socket into the hole of the washer to create the dimple. A 1/8" hole was drilled for the locating tabs on the switch.

    The door bottoms needed to be cut out to repair rust damage, and to extend the flange.  There are back to back 90* bends that are only 1/4" apart and my brake only does a minimum of 3/8" apart.  The logical thing to do is buy a milling machine to help make dies for the Pullmax, then make door bottom dies... right?  


    We actually bought a Bridgeport about a month ago but hadn't set it up yet. So I bought a pallet jack to move it, a few things to get the mill up and running, and had to dissasemble and clean the vise it came with before I could start making anything with it.  

     

    1emySD3h.jpg

     


    It came with a Kurt vise but it was filthy inside and out.  Ended up having to boil it in Purple Power to loosen up the crud enough that it could be scraped off.

    In it's temporary spot, ready for work. 

     

    JHpaLSEh.jpg

     


    The Pullmax uses 22mm posts so I bought 1" bar and machined it down to size. 

     

    nSUJQi7h.jpg

     


    I also cut a quick tool post alignment jig.  I'll make a real one out of aluminum eventually. 

     

    ZRp7qQ7h.jpg

     

    6e3LScKh.jpg

     


    First lower die attempt.   The right side is a plain 90 to hold in place a 90 that I pre-bent in the brake.  The ramped left side progressively stamps the second 90.  This design didn't have the correct shape ramp so it distorted the work piece.   

     

    ttGbsZrh.jpg

     

    JE7X32th.jpg

     


    Version 2 using a twisted steel bar instead to fully support the flange being folded over.  This worked much better. 

     

    Joex6ekh.jpg

     

    ryGgZxUh.jpg

     


    For the test runs I stuck sandpaper on the test panel and slid it in and out by hand with the machine off to show any high spots on the dies. High spots thin out and stretch the work piece and cause distortion.

  18. I want to assemble all of the sheetmetal on the frame next to start panel alignment.  That means I need door hinges, and the old ones needed attention.  The driver side upper was really worn, as was the lower and passenger upper.  The passenger side lower seemed pretty tight but it was packed full of old hardened grease that could make it seem tighter than it actually was so I pulled apart as well. 


    Before- caked on grease, misshaped door check levers, and worn out pins and bores.

    New oversized pins.  I bought a tapered reamer set which included a .3400 to .3740 reamer which worked well with .373" pins. 

     

    h97KNkph.jpg

     

    6iwxM3Uh.jpg

    Blasted all pieces. 

     

    uSelns3h.jpg

     

    y2ARUk5h.jpg

     


    Since the reamer is tapered I could set the inner diameter of the hinge brackets slightly smaller than the pins so the pin won't become loose in the bore. 

     

    94eRdi8h.jpg

     


    The mounting flanges had a lot of raised edges from the stamping and tapping processes so I flattened those down. 

     

    wairVUSh.jpg

     

    Kz8QjPKh.jpg

     


    The last F100 I restored had wide/loose notches on the stop arm which let the door move excessively on the stops.  There was also a "ramp" shape on the stop to hold the door fully open which put the roller in a bind and made the door "pop" when closing it off the stop.  These were the same way.

     

    Original shape of the ramps- 

     

    fKVlDvyh.jpg

     


    New shape.  I had to weld one ramp to get the shape corrected.  The "V" shape holds the door tightly in each stop position with no free play, and the flat ramps allow the roller to smoothly come out of the stops without binding. 

     

    Pewfamrh.jpg

     


    Another problem- the stop arm bottomed out on the hinge body, which let the roller separate from the ramps so the door moved freely.  I ground away the edge a little to make more room for the arm to correct this. 

     

    PIzsdWTh.jpg

     


    Finished and reassembled, ready to test fit the doors.

    Yep, the more you look the more you find that needs to be corrected. 

  20. Details-  the seam that was eliminated ran into the end of the drip rail, and the roof skin flange was overhanging the end of drip rail a bit.  The inside corner of the roof skin flange also didn't fit tightly against the drip rail, or the lower panel.

  21. Initial fitting of the roof took awhile to get the rear edge lined up exactly flush with the lower part of the cab.  Once it was in place I made a few tacks, then had to reshape the body line on both sides for a flowing shape through the two panels. 

     

    JBoWF85h.jpg

     

    R5Oi3kLh.jpg

     


    The sides had uneven shapes meeting at the seam from top to bottom.
