I've worked on a number of Milltronics machines. They were all 3 phase input. I would say yours was at least originally due to the 3 phase disconnect and three phase wiring that is in place.

Can vouch for Steve Belanger. Has done magneto work for me.

Re: Identy of small collets

Have to wait for the OP for the answer Bill. I posted the pics of my drill sharpener collets and holder for him to reference.

Re: Identy of small collets

My guess is they are collets for drill bits used on a Black Diamond style drill sharpener.
