1940 Packard 120 Convertible Restoration


Recommended Posts

I cut down a piece of 1" ID tubing and smoothed the edge to use as a finishing tool at the ends of the beads.  The bead roller only shapes the sides of the beads; there's nothing to shape the ends.  This "closes" the ends of the beads and makes them look finished, and also flattens the metal around the ends so the panel is flat.

After finishing the ends of the beads with the pipe tool.  The panel is much flatter now, even across multiple beads.

Finished up most of the work on the front 2/3 floor pans.  Still need to make the rear floors and pans under the rear seat.  

 

Made patterns for the other floor sections.  I only had the pictures we took of the car in Dillard GA to go by.

The original battery cover door was missing it's retaining tab so I made a new one and welded it on.

Front passenger side pan.   This side had an extra cut out for a small transmission inspection cover.

I didn't show the body mount area on the drivers side pan earlier.  Made it the same way, pre-stretched then used the bead roller.  I used a 5/8" round bead to make the straight lines and the 1/4" offset dies. I spaced one of the offset dies out to match the rounder 5/8 bead.

Got the right front corner cut out.   I cut it out in one piece instead of separating the layers like I did on the other side.  This way it's all still assembled and I can see how it goes together better.

The next section down had the mount for the convertible top welded and bolted in place.  I'm not sure if the 1/8" thick outer plate is original or not; it was brazed on and bolted.  The bolt pattern wasn't square and the brazing looks the same as the other areas that were poorly reworked so it looks like it was added later.  It did have tan paint and red oxide primer though, so maybe it was original.  I'll have to check with someone who knows the cars better.

A little bit of rust in the outer rolled edge.  Just a small spot though, glad it wasn't the whole lip.

With the last of the old floors cut out I could test fit the toe board and front floors. Fits pretty good, needs a little tweaking in a couple areas still.

I started cutting out the bad metal in the back seat area against the inner fender wells.  This section isn't all that bad overall, just a few pinholes here and there.  I also cut out the bottom of the dividing panel between the cab area and the trunk so I could get in there to blast better.  There was rust between the layers that had to be cut out anyway.

With the bottom of the trunk separation panel cut out I was ready to start blasting the body, but the rear half was way too weak to be mounted on the rotisserie like it was.  I bought more 1" square tubing and used our tubing roller to make more bracing to keep the body in shape while it's off the frame for blasting. 

 

 

The '68 Chevelle in the background is another shop project. We're just about finished with it.

I'm about halfway through blasting the body now. Once the weather dries up I'll be able to finish stripping it and shoot epoxy primer.

It finally quit raining after three weeks of almost non-stop wet weather.  Body is now all stripped and I have most of the lead melted out of the seams.  I left the lead in the left top windshield frame corner, and the top of the door jamb/quarter panel for reference.  Those two areas aren't just leaded to hide seams, they're built up fairly thick to actually shape the area.  I've never used lead as filler before so it will be interesting to learn the process. 

 

 

There is a good bit of lead in the car from the factory.  All of the overlapping panel seams in the door jambs were built up and shaped into an outside "corner" to mimic a one-piece stamping.  The lower rocker seams were also leaded to hide those panel overlaps. 

 

 

Cracks in the lead, these looked worse before blasting.

Made a video of the lead work but had to break it up into smaller clips to get it to upload.  I'm still trying to get the hang of getting the lead soft but not melted so it's shapeable.  The middle section isn't as much of a problem; it heats up pretty evenly. The edges are much more difficult to get the lead heated evenly.  The outside "skin" melts and runs off but the inside of the chunks are still hard.  I did turn the torch down a bit and that seemed to help.

I went over the area to be leaded with a wire brush to make sure it was smooth/clean before applying the solder paste.  

 

10998079_769649813153839_581439544419742

 

 

After filing the lead flat.  This is an odd area to shape, the upper half is slightly concave in both directions so the flat file could only do so much shaping.  

 

11182749_769649833153837_629084999079113

 

 

 

So I sanded it with 36 grit to finish shaping it.  I know you're not supposed to sand lead, but the 36 grit is so rough that it doesn't make fine dust particles.  I was wearing a mask of course.

 

10380217_769649836487170_406545998132145

 

 

 

The 36 grit lead "dust", almost big enough to be called shavings.   This isn't small/light enough to float around in the air so I felt ok about sanding with 36 grit.

Got most of the lead work done, ran out of lead sticks before I was able to finish the last rear quarter/trunk panel seam.  

 

I melted out the last two spots I had left on for reference and blasted the areas to clean out the rust that was underneath. The top pic shows just how far the edge was pounded in from the factory.

Way too soon to think about it now but when your customer gets to working on the convertible top assembly we can supply you with that gull wing shaped header bow for above the windshield. There is no ready source for these as far as we know. We are making a batch shortly, likely a one time thing. Very time consuming to shape. Expensive but correct.

Although I already commented on the skills/talent shown here on this project I am still wide eye looking at your update. To me this is the best kind of restoration documentation be done. Great job. On a side note though it sure looks like your building a car from a bunch of small shaped metal pieces, who'd a known that it could be done that way. :D Scott...

Appreciate the offer.  The owner has many new or good original parts already so I'm not sure if that's a piece we'll need.  Will keep it in mind though!

I cut the jump-seat base out and made a new panel.  This was an easy piece to make... the rest of the rear seat area kicked my butt... :dohh:

11392969_787368764715277_489383643863811

Like the middle pans, the only thing I had to go by for the rear pans were the pictures and measurments taken earlier from another car.  I made a (really) rough draft of a template to start mapping out the bead lines and body mount areas.  The pictures I had were barely adequate to get the measurements correct, so there were a couple areas that all I could do was make the proportions look right. I doubt there will be any show judges crawling on their backs under the car with tape measures. :lol:   Once I had the rough template in the car I made some corrections and transferred that to translucent paper.   That template still needed some fine tuning before I could transfer the pattern to sheetmetal.

The rear pans are mirrored so I can flip the pattern and use it for both sides.

11390072_787368601381960_289827147714738

Checking the fit of the right rear pan. It's not in there straight since the outer rear edge needs to be turned down into a flange to fit against the fenderwell.  Once that's done it'll slide all the way back into place.  I'm 90% finished with the left pan so I can start welding the inner/outer rockers, quarter, and front lower cowl panels in place.  The inner/outer rockers sandwich the floor pans so I needed to have all of the pans done before anything else could be welded in for good.

With the floor pans mostly roughed in I turned back to the section under the back seat.  I had the center section made but needed to make the side pieces.  The left side is fabbed and welded in, just started on the right side last week. 

 

 

 

I bent the back edges of the floor pans to fit against the rear seat floor section.  Also trimmed the rear seat pan to fit up nicely once it's ready to weld in, and drilled holes for the plug welds. 

 

11745802_802851843166969_112730148170449

 

 

You can see how the back edge of the floor pan will weld to the inner fenderwell and bottom of the seat pan. 

 

11542110_801076220011198_665429582794553

 

 

This is looking into the right quarter panel from the inner fenderwell.  The fenderwell should be covering this, so you can't see in...  I decided to go ahead and cut this area out since it was in such bad shape and the rear seat pan edges needed to weld to the fenderwell.

After cutting out the lower front fenderwell and edge of the seat pan.   It's amazing that the car didn't collapse in on itself; this was a body mount area that is completely rotted away.

Holy Swiss cheese, Batman! That sure is looking better by the panel.

 

Swiss cheese manages to hold it self together though!   :lol:  Thanks!    

 

 

 

Really nice work. As I restored a '56 Biarritz with a lot of rust, I'm appreciating what you are doing.

 

Thanks Roger!  I found your model project topic when I joined here and have been reading through it as I have time...  I'm simply amazed by your skill and paitience!!

I have the right inner fender bottom welded in, and the rear seat pan welded in on the areas that I can get to.  I'll have to flip it on the rotisserie to finish welding the middle section, there is about 16" in the middle that I can't reach from the top side.

Been working on finishing the driver side B-pillar inner brace.  I layered three pieces of 1/8" x 3/4" steel to make the 90* turn (didn't have a piece of 3/8" x 5/8" laying around).  I thought that a solid piece would be stronger than sheet metal, and that area needs all the help it can get to help keep the quarters in alignment.  Just need to do some final trimming to fit it to the car.  Making it solid also make it possible to "sculpt" the shape of the "bead" so I could blend from the round lower bead on the floor section to the square upper bead on the B-pillar, matching the appearance of the factory piece. 

 

 

11875163_817380191714134_509198492722019

 

 

Both sides had be previously "repaired" so I only had pictures to go by.

Picture is from the car we were able to document in GA/NC.  His shop is on the state line, not sure what side the car was on. :lol:

 

 

10710783_639810076137814_712069542396105

 

 

 

Also have been working on the driver side rocker.  I made the front edge too round where it meets the A-pillar, so when I tried to test fit the door the front/bottom edge wouldn't clear.  I had to make a couple relief cuts to drop the edge down.  No pics but you can see the difference between the original shape and what I originally made.  I should have made a template of the corners before I cut everything out.  I'll know better on the passenger side...

The B-pillar bracing is pretty much finished up. Had to extend the rocker panel 9" rearward so the outer B-pillar piece had something to weld to along it's outer and upper edges. This was rusted away on the original pieces so I didn't know it should have been longer than I originally made it.  Didn't know exactly how it should look so I just made it functional, it won't be seen once the outer piece is welded on.  Also pulled the rear floor pan back out to recess the area under the inner B-pillar brace.  The rocker extension also had to be recessed.  

 

I should have everything for the left side finished this week so I can pull it all out for cleaning/priming.  Then it'll be ready to be welded in.   All I'm missing now is one rear body mount brace at the rear inner fender; I started on it yesterday.  Also need to blast the original rear floor pan braces, hopefully they'll be nice enough that I won't need to make new ones.  

 

 

Top half extended.

Started on the last piece of the driver side, the fenderwell/floor brace for the body mount at the end of the inner rocker.  Still need to finish it up so I don't have any progress pictures but it's roughly shaped. I'll wait to do the final shaping once the rest of the panels are back in for good.

Pulled everything back out, then either blasted the parts or cleaned them with PPG DX579 and DX520 before spraying PPG DPLF epoxy.  I'll start welding everything in next week.  

 

 

Don't think I mentioned it before but I made a stainless table top for the bead roller.  It's hinged at the back so it can be moved out of the way for round parts, and it's height adjustable to compensate for different bead depths.

One thing nobody likes to do is attempt to reassemble a car that another person took apart.  Parts are usually scattered out, hardware is misplaced, labled wrong, or completly missing.  Even if everything is there you still didn't take it apart yourself to really see how it was assembled.  Since I wasn't familiar at all with Packards I was thinking that this could be a huge problem with the build when we first considered the job... thankfully I couldn't have been more wrong. 

 

The owner completly documented the car before and while it was being dissasembled.  All of the parts are in boxes that are labeled with the contents, and inside each box are all of the needed parts and hardware for that respective part of the car.  There are full size color pictures in each box of how the parts go together- no guesswork involved.  Many of the parts are already restored, with new hardware included, ready to bolt on and go.  This will save countless hours once we start the reassembly.  It's already been helpful with the few things we've needed while doing the metalwork.  The owner definitely wins the "best customer ever" award for having everything organized to this level of detail. 

 

 

I needed to make sure that the seat mounting brackets were in the correct location before welding in the floor pans.  So I pulled out the seat frame and "seats" box, and found already-stripped/painted seat tracks, new hardware, and clear pictures of how they're assembled.  Had it together quickly since I didn't have to hunt for random parts scattered in boxes.  

 

I also double checked the location and height of the floor braces.  All of the body mounts are shimmed with the same amount of spacers to keep the body braces level with the frame.  This will make it easier to mount the body for the final time- no guessing with how many shims go in each location.   It's all solid mounted with no rubber bushings at this point, hopefully this will help the body to remain in the correct alignment once the bracing is cut out.

The driver side seat bracket had alignment holes through the floor braces on both ends so I went ahead and welded it to the cross braces. The passenger side didn't have any way to locate it so I bolted the seat tracks and seat frame in the car and positioned the right side with clamps to hold the passenger seat bracket.  Tested the tracks to make sure they weren't in a bind, then welded the passenger brace in and coated the top side of the braces with POR15.  Took a little extra time to fit it all up but there won't be any surprises later once the seat is upholstered and ready to bolt in.

I've started re-fitting the panels so I can mark the spot weld locations.  I like to prime the panels, then mark and grind the primer off only where the spot weld will be.  This keeps more of the seams protected from rust in the future.

Used the patterns I made earlier to mark the location of the convertible top ram bracket.

Impressive work !  

 

Scary the owner was driving this around prior to your work.  

 

Also, I have seen plenty of 41 and 42 Packards that had frames without a single rust pit yet had spots in the body - and it does not take as much abuse as you think - they definitely do not have the quality of steel in them as in prior years - do not know if it was gearing up for the War or they just were doing such for cost efficiency,  volume, or......   And, the same goes for a GM, Ford, and …..

Excellent work so far! I bet it felt like finding a pot of gold when you realized everything was labeled. I'm looking forward to seeing this progress.

 

It's going to make reassembly so much easier and quicker.

Thanks!  It's amazing that it was holding together still.  

 

I think that most of the rust problems come from the metal not being sealed very well when the car was built.  I haven't noticed any seam sealer, other than lead over seams in the door jambs.  A lot of the major rust is in the seams, were two layers overlap.  I imagine that laquer primer was used on the floor pans and inner structure which does very little to seal the metal.  If there were any moisture to ever come in contact with the floor padding then it wouldn't take long for rust to form.

I need help determinig the location of the rear floor pan braces. I assume that a Coupe would have the same pans and bracing. Can anyone photograph these braces so I have a reference to go by? 

 

The ones in question are the two longer braces that stretch from the rearmost cross brace to the back of the rear floor pans. 

 

I have a picture from a '39 2 door sedan, but if I place the braces in the same location on the Convertible they come up short.

I have nearly the whole left side welded in; everything except one rear body mount brace against the inner fenderwell, the outer quarter panel, and lower front cowl panel.  Lots of final fitting/trimming/reshaping to get it all fit together well. This is where good patterns would have helped a lot, but the original parts were in such rough shape it was impossible to make 100% correct patterns.  There were 308 plug welds so far. Next step is to fit the outer quarter and cowl panel, then lead all the door jamb seams.

This is a great thread! Thanks for posting this. The only downside is that it makes it clear to me that I will never be able to accomplish a project I had in mind!

Would this have been significantly easier if you had a donor car with good metal?

Yes, instead of hand fabricating every piece going back in I could have only had to trim/fit donor sections to weld in. The floor was cut out already when I started the project so we've had to find another car for pictures and measurements so I could make templates for the missing sections. Many of the sections I'm replacing are in bad enough shape that I can't make dimensionally correct templates to make new pieces that fit 100%, so some of the new pieces need tweaking to fit before they can be welded in. So a solid donor car would have been a huge help.
