Never mind about ya boots in the shot. When I take a pic from that angle my atomic gut gets in the way.

Glad you are making progress. May not be the camera causing the blurry shot, it may well be camera shake when you press the button to take the pic or similar. To test this theory sit the camera on a solid surface and take a pic and see how it comes out.

got too many projects going on at the moment, currently 5, maybe 8! I have not quit though! if it turns into 8, 3 of those will take priority, those are paying gigs! 2 dozer work, and the other tractor work clearing land. two different roads to build with the dozer. I am going to knock out the smaller projects first or it going to snowball on me and i will never get caught up.

well got the back ache today, so i decided to take on a sit down job on the welder. first coat of locktight liquid tape made its way onto the armature where the insulation is scuffed up. I think I am going to like this stuff, even smells like it is good stuff! its a little messy but it almost looks like the stuff a motor shop would use! its going to get several coats, got to wait a minium of 10 minutes btween coats. i will get some pictures up when its done, may be difficult though its dark in the shop and that armature weighs a ton so it wont get moved just to take some pictures.

well not much to report on the welder, but i had a little time today and so decided to do some work to the cart! got one wheel took apart cleaned up greased and back together. it aint new but does roll pretty nice! that inspired me to do another, got it apart and called it a day. I will take a few pics of it tomorrow. this welder needs to be mobile at least in the shop! I will have no need for the cart if all goes well, but i need the cart to function at the moment.

That's a late model welder! It was made around the time B-17's were extremely busy! 1943.

starting to get caught up and hoping to get back to my welder! question for you guys, how to clean up the steel in the stator? wire brush, sandpaper, scotchbrite on my die grinder? with some small touch ups the amarture can go back in! and will free up some much needed shop space! i know i have been deadbeating around on it but for many good reasons, first and foremost to give it time to air out and dry!

things are starting to look up! its a tripod as of now but does roll quite easy, the center is broken out of one front wheel. no big deal just needs welded back in. so i had a little time today and took the control section apart, can you say OVERBUILT!! nothing in there hurt either! just a little cleaning was all that was needed. the fine tuning works measured from my cheepo meter it ranges from .05 ohms up 67 ohms. I have not checked out the apmrage adjustment yet because it is apart for cleaning. while i have it out i am going to run new wiring to everything in the control box. Its tight as hell in there with the amp adjust in place. I need to get after it before i forget where everything goes, I had that moment today and am going to make a note of it in this thread. 5 wires coming out of controll box, 3 go to the exciter and the other two in the generator. scotchbrite rolock disc cleaned the steel up perfectly. thinking what to use to prevent rust, paint, clear? we used clear in a spray can on transformers on parts that couldnt be dipped. pictures to come, I know how you all like pictures! vanman if you are still following i may have some questions on motoring this thing up with batteries.

Great thread, Tracy... but needs more PICTURES!

3M makes an insulating spray 1602 R, I believe that's the same stuff we used to use for insulating flyback circuits on Cathode Ray Tubes (TV sets)... I'd use that on the wiring, and perhaps even a thin coat on the polepiece/laminate areas you're concerned about...

Virginia car inspections. Another state to scratch off the list in our hunt for a place to live. Crashes are so rarely actually caused be mechanical failure that you can basically say that crashes are not caused by mechanical failure. Just another state money and control grab.

I believe the last photo in the first set is the welding polarity switch?

The last photos looks like a big choke/reactor? Does it have taps? Or a wiper? Looks like winding size varies from one end to the other.
