    Ol Dandy Dave is at the western end of PA for the show. The old 1990 Chevy Suburban did a fine job getting us here. Any of you folks around come and see me at the big Sand Box where the construction equipment is set up. I have my one of a kind power shovel with me and my small Agricat dozer.  And introduce yourself if we have not met. We arrived yesterday and will be setting up withing the next few hours. 🙂

    Years ago, when I worked at Catamount Ski Area, we had a bank of Ingersoll- Rand screw type air compressors 750-1900 CFM. Most were powered with Detroit V6-71's. The 1900 CFM had a V8-71. Guaranteed they would suck a gallon of oil in 24 hours while making snow. These ran between 1,900 and 2,100 RPM depending on how many snow guns were running at the time. The sound that bus makes is very familiar to my old ears. One of the 1400 CFM compressors had a Cummings. That used maybe a quart of oil in 24 hours if that. When the Detroit's were getting tired, they would go though 3 Gallons in 24 Hours. That meant it was time for a replace and rebuild.

    A 10 SI (3 wire) will produce about 35 AMPS max. A 15 SI will produce about 65 AMPS max. All depends on how much output needed for driving requirement. No need for old regulator. In some of the newer Alternators the field is hooked up to the B terminal on the alternator and the other wire is hooked up to the idiot light.

    Yes. There is suppose to be a fusible link wire on that terminal. If something in the alternator fails and back feeds, it should prevent a short in the wiring system and a melt down caused by the alternator. 

    Battery charging

    From experience. 10 year old batteries are usually used up. If it has not been charged in years, and you live in a cold climate, most likely the plates are warped from freezing and it will not take a charge. Also, idle battery's sulfate and will not take a charge. In both cases the battery is internally shorted. It is much better to use them and keep them charged than to let them sit idle.

    Agree that you are much better off with a 3 wire Alt. That DELCO was a good reliable unit. I've installed a lot of these on all kinds of vehicles and machinery. The biggest problem with the one wire is you have to initially rev the engine quite a bit to get the unit to start charging. Not the best thing for a cold engine.

    Looking good, keep it up.   Did you have many problems getting the later 230 engine to fit ? 

    Oh yeah. Don't do that. The parts between a 1936 and a 1939 do not all fit well. It is not a plug and play unit. The owner brought me the motor to rebuild before I saw the car that it was going in. He later told me the car it was going in was a 1936 after the engine was rebuilt. ( After all, They're all the same, aren't they?) It would have been much better to find a 36 engine and bell housing. I had to modify the transmission input shaft, Clutch linkage, Starter push button lever. And we are not done yet. Will need to use the 1936 radiator as the 39 Radiator will not fit the sheet metal. I generally don't like doing this as the car is no longer original. More to come. Stay tuned.

    Nice videos.

     

    Fred Starr in the UK has written some interesting papers on valve design. There is a free to access article here:

    There is a more detailed article here (paywall):

    Yes. Valve development has come a long way. A lot was done in WWII on aircraft as the exhaust valves were the weakest link and lead to engine failure. Sodium filled valves were found to help.

    In what application were these typically used? It doesn't look like the typical "hit and miss" engine that you'd see out in hay field. DId these power belt systems in shops? 

    This particular engine was thought to originally power a generator as the size of the flywheel and pulley are key to powering that type of unit. Many did power over head jack shafts in shops to run machinery or pump water.

    Sure enough it is a bumper jack. I remember seeing that style back in the 1970's and the jacks had a few years on them then. Looks like it got tossed because the handle broke off. From memory It is not from any particular make but more of an off the parts, or tool supply store shelf.
