Default Making A parts with lathe

Does anyone here makes (or made) his own model A parts with a lathe ?
If so, what did you fabricate ? (pictures are always nice to see).

Custom bushings for the steering sector output was one case.

The bushings they sell do not seem large enough, at least the ones I bought, for new sector shaft. That is the sector shaft fit in without needing to hone to size. I reground a very slightly worn (a bit over .001") shaft and made a bushing that was honed to fit the smaller diameter.

I have made some tools up here and there. Usually to fix stuff most people dont fix.

I have a short be Southbend 9" Model A.

If anyone is interesting in getting a lathe just check craigslist every day. You never know what shows up- CHEAP. I got one that had a little bit of way wear for $300 with some tooling. A guy at work got one that was basically new for $300. Bought another for $300 for the metal table and the 6 jaw chuck. Sold the lathe for $325 a few years later when my brother picked up an almost new 4 1/2' bed SB 9 for, yes you guessed it $300. I have to say, usually the SB 9 in decent shape can sell for $1000 with some some tools.

I was recently in need of some throttle plates for Model B Zenith carbs, not available through normal sources, so I figured out how to make them on the lathe. Now I can restore the ones with bad throttle plates. ( People thought that it was a good idea to drive a punch on the plate to loosen a stuck shaft.)

I use our lathes for making all type of parts for our Model A Fords. I have restored worn out Model A shocks using my lathe. Parts that were worn out beyond use have been welded up, and then I turned them back down to like new specifications. Door pins, brake rod pins, spring shackle bushings, drive shaft seal area restoration, speedometer drive gear speed adapter restoration, special bolt sizes, and the list goes on and on. The lathe is also useful in building those special tools one needs during the restoration of his Model A Ford.

The unique thing about a lathe is it's the only tool that can reproduce itself. An amazing fact, even if only partially true. Most of the time I am using my South Bend 9" is to make tools to work on the Car. Bushing drivers, a contraption held in a vise to mount a wheel and indicate run out, The Barrett tool for centering brake shoes, tool for fuel level, tools for using an I beam when measuring and straightening frames, and toe gauge. Having more fun on the lathe than working on the car.

A well equipped lathe is a very versatile tool. Turning, drill, knurling, polishing, chasing threads. When I started my apprenticeship in 1967, the lathe was the first machine I trained on. My shop lathe is a 1960s Clausing Colchester, 13" with a 48" bed. I bought it in 2001. At that time, used small lathes were more expensive than larger lathes. Guys with home shops don't have space for a 20" x 84" machine.

There seems to some little job I do on the lathe most days. Some small and easy, some a challenge. Those little 1/4" balls for the throttle linkages when I make a new linkage after fitting a downdraught carburettor would be about the simplest I've done recently. Sometimes, I surprise myself with what I remember from school days when we were taught the basics. I'd be lost without my lathe!

Hey George,
Your skills and creations are amazing...to me !


Timely subject this is. Today, I went to help an older timer with one of his projects.
He is a former aircraft machinist and marine. He makes small parts while I watch at times. He makes it seem so simple.


Well, today, I made my first part ever on one of his large lathes ! Wow, fit perfect. He stood by and verbally guided blind hands to success. First he went thru a litany of the machine part names/nomenclature(?).
This guy builds almost everything that he needs for a car, very custom.


He smiles as I tell him of the crude tools/methods that I use to make something and/or something to fit something i.e.- grinder/vise/hand tools.


Wonder if I need to get a lathe now !!!

I have a South Bend 9"

I have made many tools and parts.
Tools such as bushing drivers and for setting up rear end gears.
Parts such as thrust washers for distributors.
Have machined 7 tooth steering shafts for new lower bushings
Have bored out 2 tooth sector housings for a seal (using an expanding arbor that I made on the lathe).
Have used it to check runout on drum hub flanges

I am sure there is more...it is a great tool to have.

In my day, that quote originally was meant to read: "The milling machine is the only machine that can duplicate it's self". Now you also have the digital duplicating machines too. I also use our lathes to turn down the commutators of the model A Ford's starters and generators.

I chucked up the gears in my trans in a lathe to get them nice n square. Just kept slowly creeping in till it was just barely cutting all the way across the gear tooth. Very quiet trans now that shifts like it has synchros.

Make special model A tools, rework reproduction parts to make them fit, weld up and turn down wore original parts. Repair parts that the wife brings home from work. You can chuck a tight pickle jar lid in it and unscrew the jar. Face flywheels.

My answer is yes you need a lathe. There is not much you can not do on a lathe.
make sure you get a 4 jaw chuck, that is what I use most of the time.

Ditto on the 4-jaw chuck. Having both inside and outside jaws is nice too. Even better is a collet set.

Used my old Montgomery Wards (Logan) to make my babbitt molds for T,A,B and V8. Really don't like those other ones, just A's.

Undercut the oil pump shafts and any other thing that seems in need of a lathe.

I make parts for the 1934 Ford on my lathe with a 12" swing. Here is a look at some of them. Roadster pivot bolts, and extended nuts to mount the Dual Temp Gauge. No one is showing what they make for the Model A so I am showing what I make for the V8!

In 1960 we cut one bank off of a 283 Chev block to make a 4 cylinder engine for a midget race car.
We made the crank from a 6 inch round SAE6150 billet in a lathe.
The engine made 240 hp on the dyno and won the first 4 races it was in but the block broke from lack of support from the missing bank.

A model A crank could easily be made in a home shop this way if someone had the ambition.

That's a LOT of Ambition, too much for me.

One of my fellow racers has Bruce Johnsons old Crankshaft lathe in his shop.
A massive hunk of iron.

I am on the lookout for a good cam grinder............J

I've turned down brake cross shafts after building up with weld, similar to KR500. I've turned up new carb venturies in brass, made bushes for front axles, modified 7 tooth steering column shafts to take chevron seals, new lower bushes for the same, gudgeon bushes for my Durant. Windscreen frame pivot bushes for dads Phaeton, and more including various tools. I also have a mill and repair parts and make tools with it as well.

I have subscribed to the homeshopmachinist.com for 30 years and even as a journeymen toolmaker . They have lots of small projects for the lathe and mill. They also show you with prints how to make small flathead engines like the rupnow , hit-n miss and others.

Slammin, You are undoubtedly right. Whenever I have contemplated a machine purchase, I make sure I can get everything that belongs with a machine. In buying a lathe a drawbar and 5C collets are a nice addition. I had trained on a lathe when I was an apprentice. The company I apprenticed at (Bell & Howell) had everything. The old timer made sure I knew how to use all of it. Cutting right hand, left hand, double lead, and triple lead threads. The lathe I used as I recall was a Monarch. It was equipped with a lock in feature to have carriage feed pull the tailstock in for drilling or reaming. The lathe is only limited by your imagination. Seeing George Miller using a Winona or Sunnen grinder for doing a crank proves this out.

Thank you George, I will print those two off. Very interesting.

I assume the electric motor/grinder on the cross slide can slide backwards and forwards in the angle iron frame as the crank turns.

Yes it is really a grinder we used in my Dad garage to grind rod journals in the car. Some times some one would have one rod bearing go. With this you could grind it in the car. We did it for other repair shops also.

earlier in the week a friend had a Model A front axle the spring perch was wore out. So we put a bushing in it with my mill.

But that is a job you could do in a Lathe. It would be a little harder but doable.

Many thanks briphaeton, that is very interesting. It looks very similar to George's equipment.

It was accurate, but it took a lot of operator skill to get the tapper out and stop grinding at the right time. We did many and never had a come back. It made the journal round and to size. I think the biggest problem was the rest of the bearings had went the same distance. We always replaced all the bearings not sure about the ones we did for other shops.

I agree with George. A older auto machinist friend used to grind crankshafts and bore cylinders at the customer shop, yard or home in the frame without removing the engine. Tractors and diesel trucks mostly. I ran across the photo of the crankshaft grinder to show him. I think the tool is only as good as the machinist and only a poor machinist would blame the tool for mistakes. My machine shop teacher showed us, he could cut a good thread on a worn out lathe that did not repeat.

Yes we did that to boring the block in the car happened a lot back then. People did not have a lot of money and many came from the depression time frame. So they only want to fix what they had to.

The boring machine has a vacuum setup that sucks the chips out as you bore.

Interesting, as that 'job' (cutting good thread on a worn lathe) is the first/only job that I did several days ago. 'Teacher' advised me that his machine has some wear and how/why to make adjustments for that wear.
I have no idea whether he was just training on the worn idea, but he seemed to be a perfectionist at his trade.


For those who do not know George, if they look at past threads (of his work posted here) they would see that he makes OHV Heads on a lathe !

I make a lot of parts for cabby's and a400. Most of my dies and patterns are made on mill, lathe, drill press, shop press. And of course several types of welders and plasma cutter.
Also English wheel some
