Wouldn't you have to connect directly to the rusted chips?
Connecting between the t-slots and the carriage sounds like a dead short to me, and a good way to let the magic smoke out out of your battery charger.

I figured that is what Dave meant Willie and my thought was to make a probe and insulate the sides with some rubber hose. Sort of a (very) poor man's version of EDM (sort of). However, given that the chips are rusted to the inside of the slots, it most likely will be a short. I'll wire a lamp in series which should provide sufficient protection.

no more so then the set up that Mayhem already has for removing rust by electrolysis, just build a dam that will hold enough liquid to keep the anode off the carriage

Ahhh... I see now. I misread Dave's previous post.
The anode would be suspended in the electrolyte running down the center of the t-slot.
Insulated from - not
connected to the t-slot.

Don't worry Willie - it's obvious I didn't read it correctly either
But I was checking in on my phone (so that is my excuse). I probably will still insulate parts of the electrode to safeguard against any shorts. Won't be trying this until I have finished the drilling on the steady rest, as I need to strip down the set up I have in place first. There are just too many things to do...

Nice work, noticed what look like lead in's on the bearing carrier, are they cut with a laser or water jet?
Free advice is worth exactly what you payed for it.

Thanks Greg - I get the off cuts from a laser cutting place, which is why the lead in holes are in my parts.
