Can I use a dremel to cut the comm and if so, how? I can't afford a lathe, and LHS doesn't do it.

[Grizzbob]

Yeah, the whole point of a lathe is to get the comm back to turning as true as possible, & without some way to mount the arm & hold it perfectly still, the cut won't make it turn true, which would not help you any.... :)

I mean if I lock the armiture in the dremel and use it to spin the arm and use maybe fine sandpaper

[Grizzbob]

No, that will not true the comm, just make the surface look better. If you do that, when you put in some brushes & run it, those brushes will bounce badly, & they will chew each other up quickly. that's why the comm must be true(that means perfectly round, by the way), & a lathe is the best way to do that..... :cool:

u know if i were u i would rather not.. 1: the bits that the dremel company supply will give it a course cut unlike diamond bits that will giv it a nice clean cut. 2: with a dremel it will be challenging to get the cut even you might go too deep on a spot and ruin it. so if i were u i would go to your LHS and see if they can cut it for u or go to your local track and have a guy cut it for a small fee, slice of pizza, or a soda.
