    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. 

    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.

    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.

    Just two quick photos of work that even a tractor mechanic wouldn't do.............

     

    Model J Duesenberg rods......with JB Weld to ballance them..........yes, this is a real photo of an engine that someone paid to have rebuilt. You can't make this stuff up. And YES, it was a numbers matching open car that was very well known. Remember, the guy who did this is still in business and charging for his work. You can see the newish pistons on the rods. And to answer the question before anyone asks........it's not a car from our collection.

    To be PC I’ll say WTF on such an assembly. Did the builder think it wouldn’t be driven?

    I am curious:  What is the proper way to balance rods?  

     

    Thanks,

     

    Paul

    Typically you’d weigh all parts of the reciprocal mass and have them equal before dynamic balance. Add or subtract weight to pistons, pins or rods before assembly. Typically find the lightest in an assembly and remove weight individually to match. The crank is dynamically balanced and has weight added or subtracted at the throws. You may look at a crankshaft and see what looks like a drill tip in the counter weight area. This was a point specific area of weight loss by drilling material. Sometimes babit is added to an assembly. 

    I hope this is helpful

  5. XW2500 Dixie Chopper repairs, 4 wheeler maintenance and repair along with all types of outdoor power equipment tune ups. Of course there was tractor activity! Box blading a drainage swale for Dad off his new garage. The view from the garage overlooks Cumberland Gap Mt. 30 miles away. Beautiful part of the world 

     

    @edinmass I did respectable tractor mechanic things!!! 😂👍🏻

    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.

    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.

  8. Chapter 7

     

    With the water pump straightened out I turned my attention to making a new Hardy joint and cleaning up the generator and distributor. 
     

    I had to cut the old joint apart to get the assembly off. With nothing available for a Haynes, I got creative. I found some corded conveyor belt that would work for material. Using a 3-1/2 hole saw I popped out blanks. Once two pieces were bonded they were about the perfect thickness. The I drilled the pattern and that was done. 
     

    Then a quick cleaning of the brushes, commutator and distributor. I add a new field fuse, cleaned and gapped the points. I forgot to get more pics of that. It’s a Leece Neville generator unit. I wrapped the frail dual wires from the distributor until I get the correct replacements.

    Bob! Great to see work being done on the Haynes and some excellent work too! 

    Don't forget we have laser and water-jet capability at my work! 😉Thanks for the shout-out above too! I'm certainly going to follow along your progress.

    Thanks Greg,

     

    I wish we had a water jet when I made my hub nut wrench! I crudely cut a scrap piece of 1/2 drop out with a torch and then cut the eight sided 2-3/4 nut profile out on a prototrak mill. Easy but not as nice as it could’ve been had I profile milled the whole thing. That’s more time than the thing needed invested though!! lol 

     

    I sure am glad we grabbed those plugs from you!
