My 1910 Mitchell "parts car" project

That I did. Sadly, all too many great old machines with lots of life left in them have ended that way.

Even though I'm stuck with woodworking right now some progress is being made.

This arrived earlier this week. The grey surface is a result of the nitriding used to harden it. This also allowed us to leave the ends soft in case they still need some work. Since I made the timing gears and my friend made the cams (in Australia) it wasn't possible to fit the gears to the cams as they were being made.

Unfortunately, I won't know how well it works until the engine is back together but it's another major step toward that goal. I actually had two originals... both in terrible condition. For some reason, the Mitchell company used a flat lifter profile on their later Model T* engines even though the car has roller lifters. They also incorporated an oil pump, which the earlier car didn't have. We chose to make the cam with a roller lifter profile and to add the cam that drives the oil pump. The timing of the cams was taken from a study of Model T Ford camshafts as the nearest we could come to a modern scientific study based on the rpms and breathing characteristics of early engines.

 

I know it is hopelessly confusing now but it probably wasn't so in 1910... the Mitchell 4-cylinder touring car for 1910 and 1911 was designated the "Model T". Their 4-cylinder runabout was the R and their 6-cylinder touring car was the S.

I misplaced the router bit I needed for my window project and had to wait two days for a new one... so I took the opportunity to do a little work on the crank bracket. I bushed the hole with thin wall, iron-bearing bronze. This is a material intended for shafts that turn intermittently but under great pressure – ideal for the hand crank. It took 3 bushings, one on top of the other to fill then entire hole and, because they have thin walls (1/16") and are tight, I made a little aluminum plug that fit into the bushing and still passed through the hole. I actually neede my 20 ton press for this. I then drilled and rethreaded the hole for the little Gits oiler and discoverd, NOT to my surprise, that the hole wasn't in the center. This really doesn't make a difference,. All it does is allow you to put a drop of oil on the shaft of the hand crank but it annoyed me so I've fitted a 1/8 pipe plug that I will mill off. Then I'll re-drill and thread the hole so it is in line with the crank handle.

The piece of heavy angle the bracket is bolted to will allow me to machine it without having to rely on grasping the highly irregular casting in the vise.

Hello Joe,  Did you get your window project done so you can work full time on the Mitchell?  Nice work on the crank assembly.

Not yet... Thankfully, we're having a mild winter so far. Of course, my notion of too cold and any normal person's are at odds. I've lived with a marginal heating system for so long if the temp gets above 45 I think it's almost hot!

Never MADE the time in the 10m years here!! Wow, a day of balz out frenzy by me..moving SO many things lost in storage boxes for years.. Look at the cool old coffee table (I repainted only it's top at 8pm!) Dried FAST near woodstove!) I added as the last thing late last night!!!   This morning  I put a "few things on it" >> Hey!!!... I am putting ONLY special to Me, and MY son Joe's things in this room...a big couch was nearly the only thing in there...a SLEEEPER couch..we will use this for friends or anyone who "needs" a place to stay, for a day or....who cares!!

I agree... but I wrote that on the 12th. We were having a mild winter. It's only since then that everything has gone to hell-in-a-handbasket.

Good to see you back Frank... I'm to busy just surviving in this weather to do much about cars right now.

BUT..hey, since I posted 3 hours ago?  My faithful VW wagon had to get towed home....first EVER time it did not get me home in ten years as my ONLY daily car!!..! Snow not a dusting like was said..My son got a call from my Banks teller, (I don't NEED a cell!! or triple A)..he is Ice fishing in town with other Big boys... they grabbed me to go get our trailer 10 minutes away, snowing good,.. we got her loaded FAST,,,and home...fishtailing the big black 4 door Diesel K3500...we ROCK!   I did want to stay at the bank while they fetched the trailer... oh baby... I sure can chat dem purdy cuties!! We were gonna go tobogganing if customers slacked off from the snow!!!

Well, not quite asleep but not paying attention. I noticed what you'd written AFTER I typed the response. It's damn cold here and I hadn't started the fire yet or had my first cup of coffee!

 

Cheers,

Well I left just before Christmas to come down here to Florida to visit family for the holidays and will be heading back tomorrow into that cold that we just missed. The wife is not thrilled for sure but I’m looking forward to getting back to working on the cars, cold or no cold. I don’t do well with this relaxing stuff. Happy new year all.

Hey, Cold?  I was up at 2am today to stuff the woodstove as it was FIVE BELOW F !  No end in the forecast to this "natural?.. LOL" severe and RARE frigid cold in sight!!  I just (9am) looked out our South windows to our lot..my sons big black 4dr K3500 Diesel is still sitting there...He and a friend went out for Diesel additive last eve, as most all Diesels are now gelling as they go down the road...it's the added wind-chill on the fuel lines & filters...! Ok, he had said even some gas jobs are failing too!  So I then looked out to the top barn where my 66 K20 Camper Special is garaged... no tracks in the snow, so he did not try to take that one to get to his Town DPW job this early morn... I KNOW that ONE will START! and will get there!  LOL.. 

 

 

 

edit...I just called my son, thinking he got a ride to his work...nope, he is in his end of our home...he did try to get there in that truck, (the dashboard outside temp showed 10 BELOW Zero!! at 6am!)but he had to turn around and fight it back home, it was gelling-up... we do have more options for two! spare reliable vehicles that are here, my 66 k20 and his unregistered vw late model gas-engined jetta,...oh... my own daily driver1970 vw t3 wagon broke down due to a non working efi fuel pump on Saturday just as the snow started at my bank, but not fixed yet, and I do have spares...and we will carry on... no biggy...lol

Well Joe, the NWS forecast keeps going up fast...The drifting due to super high gusts ...then they say trees down, followed by more zero temp spell...but it breaks on Sunday night! staying a tick under the normal to Me "Jan/Feb-20F nights"..  I am lucky, on a MAIN State Route! AND wow, I have power coming from the North to my shop and streetlight in my lot, AND power comes from the south to my actual home!  I learned that from TWO past texter accidents taking a pole down on either side of ME!!   I have a vintage generator that can run the fridge, and a small "suitcase honda one for small stuff.. I have a LONG new cord to run up from shop for maybe to start the fridge? Not sure on the long length of cord dropping start up amps/volts loss?

 

But, I don't get why it is  to affect NORTHERN CT and Northern RI?  Not like a coastal ?Nor~Easter really?  Sky was so weird this morn near daybreak! Vibrant pink and sky blue stripes, down low, due south! Bright Sun now!  Well, I won't see my Son for a long spell as it gets here tomorrow night!  His phone went to recorder instantly??, when I called to see if his diesel truck got him there at 8am.. I said rest up buddy! drifting snows later on, after snow stops, will keep the crews on for another day? >> IDK, the weather just is too weird these times, to know anything at all!  Bye.

Frank,  I've laid in a stock of wood and a tank of propane for my auxiliary heater. This cold snap has left me with some serious plumbing problems that I'll have to address next week. At times like this I fall back on the old saw "that which doesn't kill us makes us stronger." Unless the predictions are way off (as they very often are) I'll stay home tomorrow and plan how I'm going to reroute the water lines. I'm half through sorting through my "plumbing box.".... I'll finish that up on the weekend and round up a friend to help with the fixes next week.

 

Take care,

I'm just fine here...Son will be gone, and he ran us out of heating oil...well he did order it yesterday, but was told it will come today OR next...but during heavy snow tomorrow?  IDK, as it comes from barely 1/8 mile away!!...lolol...Guess what, I simply don't care, I use wood on my 2/3rds! Ok, no running hot water now, but I can put a big pot on the gas stove OR the woodstove....just like 300 years ago!  If his underfloor heat pipes blow, I scrap the oil hot water system for good!  Use a 2nd woodstove! Simple, Eh? and CHEAPER, not tied to oil greed barons..I went shopping with my 1966 truck, had a blast as it was SO crowded with so many ethnics!! Rockin it easy here! 

 

maybe tonight or in Am?..Going to make a BIG pot of stew like?..... "kinda" soup?, got some tips from maybe a young grandma or elder Mom? from PR, She can't speak "Englaise", nor I can speak "Hispanics"...lol...but we got it all sorted out!! (her stuff in her cart made me ask HER!)She did not offer to come help though! maybe if I said I'd peel the taters? IDK!!

 

got more wood split, easy fun task!...then covered everything for high winds...brought in 2 days of wood... I am good to go...fragrant candles bought today, even bought stick matches like the old days...lol.. aaahhhhhh...

 

oh, felt like a new type of lyme flare up at the store. legs giving out a bit, had to cancel 11am Lyme Dr visit tomorrow due to me not going out in that NWS predicted-mess! I run ME, not them!, it's only 10 minutes from here!...was just a mid-treatment speaking meeting, can be done by phone! .......see??..easy if you do what you need...for YOU! 

 

EDIT next morning, at 5:30 AM, the oil guy shows up! My son Did put in 20 gallons of diesel last night in case the oil trucks could not go in the snow!  and he could not get the furnace to bleed out and fire...so daddy had to show him AGAIN!! lol.. we are golden now! He is at work, rolling, as I just let him know we got oil! Should be a wild storm,. oil guy says they have been going 15 hour days! for a week?, and is hoping to get all the "low-on-oil calls" done before the drifting starts! Bye again..

Hey Joe and Friends who like OLD cars.. I kinda went for a walk in the snowstorm yesterday, scouting a possible way to go to the Oil Company to pay my bill,,,with my newly built Star Doodlebug.  I was like being a Kid again, walking slowly in light snow, no wind, exploring on foot, then...GO get that STAR!!  I had a blast, and boy, the snow was a challenge with the outback trails! But I made it there, then took the main road home, as I knew I'd never get back the way I came! Enjoy my "Teen Years" pics if they work!!! LOL

Back in the 50s and early 60s my uncle used to borrow his neighbor's 1926 Lincoln to drive into Providence in weather like this. The car was known locally as the "stinkin Lincoln" though I've no idea where that name came from. It was a Dietrich bodied cabriolet, bought new by a neighbor's father and was the only car in the neighborhood that would go through the heavy snow... he lived on a private road in North Kingstown and worked at Brown & Sharpe. I''m told that occasionally he'd have to pick up another neighbor, Henry D. Sharpe, to get into work. In the late 60s, my cousin Geoff bought the car. He built a garage for it, to store while he was in the Navy but never got around to restoring it. A few years ago he sold it back to the son of the original owner who is, I believe, having it restored.

Seeing the photos of the Doodlebug out and about reminded me of a story my Dad told me. He lived his youth up here in Northern, Maine in a little community called Parkhurst Siding just northeast of Presque Isle. Its claim to fame were the rows of potato houses lining the branch of the Canadian Pacific that crossed the border at Perth-Andover and ended at a station and turn-table in Presque Isle. Both my Great Grandfather and Grandfather were section foreman on it. During the war there were no new trucks available for the potato farmers so they had to make due with what they had. Even when the war ended it was hard to find a new truck. However, one farmer did find one - it was a brand new International KB5 or 6. I had a KB5 for awhile - I pulled it out of a farmers back 40 and paid a whole whopping $100.00 for it. Even though it had sat for 10 years it ran like a top though the tires had long since fossilized and it had no brakes. Shifting into third was always an adventure because you were almost guaranteed to smack your knuckles into the dash.

 

Anyway, One day, shortly after he got it, his boys rolled it over crushing in that nice domed cab roof. When the local body guy told him he could fix it the "Old Man" simply pointed to the top of the cowl and said "Cut the son-of-a-bitch off right here!" (famous northern Maine lingo) and it duly was - the entire roof, windshield, everything - from the top of the cowl up. Everyday, all winter, my Dad saw those boys driving that truck to school in Presque all wrapped-up in horse blankets - with the Old Man following behind in his Caddy making sure they enjoyed every moment of the trip.

Every time I think I could move to Maine I remember that you get several months of this weather every year (as opposed to a few weeks, and not every year). I've never had any desire to move south but I have lost any affinity I might once have had for cold or snow.

I decided to take a break and make something for the Mitchell. One of the really cheesy features of the engine is the oil filler/breather... they screwed a 1/2 NPT pipe elbow into the side of the crankcase with a short section of iron pipe as the filler tube. I presume it once had some sort of cover that allowed crankcase ventilation but that was long missing. Here's the crankcase...

 

IMG_0317.thumb.JPG.e05c88e80c4e4253cddb6ae192565541.JPG

 

However, there is a boss of some sort at the front edge of the case with what looks to be a plug in it although the plug isn't visible from the bottom. This is the place where the breather/filler should be, at least according to PM Heldt's engineering textbook.

 

IMG_0318.thumb.JPG.9e6a55415417dfe4dec64be8180f844e.JPG

 

I decided to move the filler up to the front and to make it from odds & ends from my boxes of scrap and miscellaneous bits that are "too good to throw away." The first part was a piece of a valve left behind by the previous owner of the building I'm in.

 

IMG_0316.thumb.JPG.be7a8ad416fdddaed6f24536edab416c.JPG

 

The piece is gripped by a section with a 3/4-16 thread. I will screw that into the crankcase. I turned the other end down to 1.070 and shortened it a bit.

 

IMG_0319.thumb.JPG.74d5d8e1a23f4180ffbca537342feae3.JPG

 

The vertical tube is an old bronze pipe nipple with the threads cut off one side...

 

IMG_0320.JPG.d41862fd25a84f08e402dafec3f3faca.JPG

 

The inside dimension is 1.070 so this will slip over the base I just made. The other end of the nipple was turned down, supposedly to 1.25 but I made an error and took a little bit too much off so fitting the upper end of the tube will take a bit longer. For that end, I raided the scrap bin for a piece of brass. I have a few brass offcuts purchased on ebay for very little. This piece is too big, but cheaper than actually buying another piece the right side. I'm going to want a finished outside dimension of 1-1/2" and I think this is close to 2-1/4.

 

IMG_0321.JPG.14396338e27bae2292ce0760be40be05.JPG

 

The top end goes in the lathe to be bored to fit on the tube. Those remnants of the threads are actually useful as they will help the solder joint.

 

IMG_0323.JPG.2fc475c8e778edaa99a5d1430604f639.JPG

 

With the top bored to fit the tube, I soldered it together. I sometimes use this little setup for soldering, a camp stove to heat the pieces. In this case, it didn't' work though I think that was because I was using the wrong solder and flux.

 

IMG_0322.thumb.JPG.053a20261c7c21a6bedc5d253d288382.JPG

 

The next morning I brought some in from home and did it over... this time it was very successful... and I used my acetylene torch to heat the parts.

 

IMG_0324.thumb.JPG.8166d34e1ab592c8dba5b7a7d2be80a9.JPG

 

All soldered together, it went back in the lathe to have the end trimmed and the diameter of the upper end reduced.

 

IMG_0325.JPG.575454ce98f24e6a5ac7da7069bb971d.JPG

 

All that is left now is the threading. I have two broken water pipes to fix tomorrow but if I get them done, 'll go in Sunday and thread the top end. The really tricky part is the cap... but that will have to wait for Monday.

Here's the filler/breather set up in the lathe for threading. I'm using 16tpi, a fairly fine thread. There are several reasons for this. Fine threads are shallower than coarse threads, the Silver Ghost RR filler cap, which is what I'm "sort of" basing this on also has a fine thread and, most important, the fine thread will simplify making the cap which is actually the most challenging part of the job.

 

IMG_0327.thumb.JPG.f5d46721b196e459f93a623358d1b0c5.JPG

 

Here is the finished piece. This will now serve as the threading gage for the cap that will made from the scrap of brass on the table next to it.

Nice job.  Could you post a picture showing how you have the indicator attached on the cross slide?  I'm guessing this is the indicator you talked about using to measure the depth of cut.

Sure, I'll take some photos tomorrow. It's a very simple system and has made a world of difference in my work when trying to hold a close tolerance. This would be an excellent addition to your lathe. You can see it better in Post #16 and post #25. Take a couple of photos of the back of the cross slide on your lathe and I'll give some thought on how to adapt it.

Here are some photos of the indicator mount on my lathe. The goal was to attach the indicator so that it will travel with the crossfeed. It has its limitations in that it doesn't act on the compound but so far that hasn't been an issue at all. In this case, the bar that holds the indicator is attached to the cover at the rear of the crossfeed. I also thought of attaching it to the side but didn't want to take it apart to drill and tap the necessary holes. Nevertheless, that might have been better although it would prevent the tailstock from being positioned up against the saddle.

 

The piece of 1/2" rod at the back allows setting the indicator at zero regardless of the size of the workpiece. Again, it doesn't always fit and at least once I had to remove the back piece but so far it's been useful on about 99% of the occasions where it was important to hold a tolerance of .001. I used the largest diameter B&S indicator I could find... the larger graduations make it more precise and I can see them more easily.

And... for the oil filler/breather, I selected another piece of brass scrap for the cover and set it up in the 4-jaw chuck.

 

IMG_0335.thumb.JPG.d8ee5a4f001312c267945f3462ee8fcb.JPG

 

This was drilled and reamed to 1" so that it would fit easily on one of my expanding mandrels. I wanted to get the faces square and the outside and inside absolutely concentric.

 

IMG_0336.thumb.JPG.033bb631db56a12bfa3995e742afc66d.JPG

 

With that done, I put it back in the chuck and used the mandrel as an indicator point to perfectly center the piece.

 

IMG_0337.thumb.JPG.aa19a8cb18683f4c0f247806ad7c5088.JPG

 

I then bored the piece to 1.418 – the minor diameter of the threads I cut on the breather tube. I may have slightly miscalculated that because it turned out to be a tiny bit too small. That only wastes a little time where getting it too big would have ruined the part.

 

IMG_0338.thumb.JPG.28134924f05b6e6623dfa180431d2021.JPG

 

IMG_0339.thumb.JPG.df022682001528609bf9fd30fa585d15.JPG

 

With the piece bored, it was ready for threading - and it looks as if I forgot to take a picture of the threading operation. The threading tool looks like the boring bar but has a 60-degree "V" cutter. When threading, I take very small cuts, no more than .005, so it is tedious and you have to be very careful because the finished size sneaks up on you... a few thousandths over and the part is loose. In this case, I got very close and used a little 120 Clover to finish lap the threads. I'm quite satisfied with the result.

 

IMG_0340.thumb.JPG.5b89a506a4fe8de69b35ad5dc8257bb1.JPG

 

IMG_0341.JPG.0690e8f8fa18dd008e81d43863f292d7.JPG

 

The cap piece is about twice as thick as it will be finished. That square of brass with the red dychem on it will be the top of the cap but it was 4:00 PM when I finished this so I'm leaving that job for tomorrow.
