Hey Bob. Looking good! Very nice! Glad you are moving forward. We are just now working on getting old tires off. We found some fairly new white walls in Tucson Az last year. Still don’t really know what we are going to do about the engine.

Thanks Roy, 

Hopefully something will work out with your engine soon. Good deal on finding the tires! What a relief it is to have a good rolling project. I’ve learned a lot and hopefully I can help you with information on your car.

Coming along nicely... Great job on the water pump shaft repair!

Thanks, I was concerned that pressing off the impeller to make another shaft would break it. So luckily I’ve got access to our flamespray equipment. I undercut the shaft .035 and then used a coarse steel shot media blast on it. The material was applied is four light coats. This allows for less heat saturation which provides better bond and eliminates distortion of the part of which it’s being applied. 
 

The chrome, nickel and molybdenum takes special care when turning but makes an excellent seal surface. Abrasion resistant far beyond the mild steel of the shaft and perfect for the rope seal and bushing areas. This really saved me a lot of time spent in fabricating new parts. I did have a friend spray the shaft of whom is the best I know with the application of this. There’s an art to it, somewhere between painting, welding and torch cutting. 
 

Last week and this week progress is slowing unfortunately. Mowing and taking care of things for my in-laws and dealing with other family responsibilities will slow me down a couple weeks. Along with my pesky full time work gig! Lol

Headed four hours away to my dad’s after I finish my coffee this morning! Tis the season for zero turn mower, 4 wheeler and tractor repairs.

I realized this morning that I’d not put you in the earlier thread thanking some folks. You’re in the group. Thanks for your help with information particularly with the Boyce parts!

I pulled the big by large starter off. It’s a large Leece Neville unit. I cleaned the brushes and commutator along with the bendix. 
 

It spins well on the bench but I believe needs to be completely torn down and gone thru.

L-N units are typically 12 volt even in the teens. Seems they were popular on aircraft engines more than cars and trucks. I’m guessing it’s a two wire system.

After spray welding the shaft I’m surprised it could be cut on a lathe. I would have expected it to be so hard that only a grinder would touch it.

If it’s applied with too much heat you can’t cut it. It cuts well when applied correctly but cut it to fast and it work hardens then you’re done. When applying the metal powder it it’s too hot it basically burns the material. Too much gas pressure on the acetylene side can do this. Or, too much buildup too fast instead of light passes allowing for cooling and not heat soaking the material. 
 

We typically use ceramic inserts when cutting it. Small jobs can be done with carbide like the brazed tool I was using in the picture. The carbide breaks down when turning  larger items.

The manual says I can use a 6 or 8 volt battery. The starter and generator are very well built. Heavy duty internals on both. Working on such solid old pieces  is really enjoyable. I wish everything was built with such durable and serviceable materials and engineering.

Chapter 9 

 

The old Rayfield carb needed to be disassembled and cleaned. Luckily everything was is great condition but dirty. 

I forgot to take good before pics. After disassembly and hot tanking the carb, the main body got a very gentle glass beading. I didn’t remove the the center assembly. I was afraid the screw that anchors it to a butterfly could break. I cleaned everything well and washed the carb again thoroughly. 
I’m very impressed by how well made this carburetor is! The Rayfield M3 all cleaned up and ready for reassembly. 

After reassembly it looks like a piece of industrial art to me! This has been a very fun project. Time is becoming an issue at the moment so I’ll be adding updates as I can.
