    OK, the *bulk* of the current will go thru the path of least resistance, all other paths in proportion. Happy now? And usually this is the shortest physical path to the ground cable. If your ground...

    You know, I have used roller positioners that had standard pillow blocks bearings with the current going right thru them. They ran for a couple years on a daily basis with the balls getting all arc...

    I still think maybe the most realistic way to go, is to hang it up on a tree or something, and paint it with truck bed liner. They have it at Walmart by the gallon.

    Most shops I've ever used a positioner in, either bolt the ground directly onto the work (preferred) or use a strap against the shaft. Some guys have rotary ground clamps, they even have magnetic...

    I wonder how does big boats do it, like in the navy? Maybe you could paint it with some tar type stuff? Rubberized driveway sealer or undercoat? Not perfect but its better than nothing. Actually that...

    Basically thats the truth. You buy a grade 8 bolt that looks a bit yellow or gold, thats zinc plating. If I had the time and money, I would lay down a base coat of heavy copper, then go over that...

    Yep, mud wasps in the brush holders. I've lost count of how many times I've seen that on the older welding machines. (Generators) Mine was the same way, a 1950 Lincoln welder. Guy I got it from said...

    Glad you found it, and thanks for getting back to us! Where exactly was it, was it jamming the brushes or something?

    Unfortunately I can't help much but I just wanted to say, Damn that's a beautiful motor. If it just sits there and hums, I would think that whatever starting mechanism it has, is having a problem. I...

    For jobs like that, I like to get the oldest, most worn-out kitchen scrubbie (scotchbrite) that I can find. So worn out that it maybe even has holes in it. Soak the part in very light machine oil...

    It's funny, I've spent my life in the shop on the job, but rarely offer anything. I come here to relax because of all the other know-it-all types at work. And yet at work, I'm usually the only one...

    Yep we used to have an 80 ton Buffalo at work years ago, it would pop a 1-inch hole thru 3/4 plate without making a sound, all day long.

    Never milled plastics, but it sounds like its related to Micarta in the way it uses cloth. Is it a proprietary type? Some quick googling shows this: https://www.wshampshire.com/ryertex/

    Sinker EDM would be my choice. BUT I'm not made of money, so I'll have to keep my eyes open for a shaper. I have no means of making straight things as of now, only round things with an annoyingly...

    In that case you might have dried out hydraulic seals, surface rust and chewed up wiring. I don't think any of that stuff is major, it could be one heck of a deal. Last time I was pricing out new...

    Yep the hydraulics is the big item. Pay attention when moving it, the ones I've used are top heavy, with clearly marked lift points. We never had to get blades, they can be re-ground quite a bit....

    Was gonna say, I would be afraid to run a flycutter much faster than 200 RPM in any case. Even if everything holds together, I can't afford that much HSS.

    I've been known to transport large objects in pieces, a bit at a time, and reassemble them in their permanent location. lo-buck, but effective, good way to build neighbors too.
