I believe most "average" comms are around .300" or so. A standard comm size shouldn't go much below .270." Much lower then this and you will get some really bad shorting, high amp draw, no power, and a ton of heat.

Mid sized comms and large sized comms are different. Check with their respective manufacturers...

If the magnets are still strong in the can,your best bet is just go out and buy a new arm.
If the magnets are weak have someone zap the can if you know someone who has a zapper,if not go out and buy a new motor..

Whether its practical or not, there is (was?) a company that sells the equipment to machine down the comm and install a sleeve over it that restores it to original diameter.

I asked Joe Pillars from Orion about com size and he said the rock bottom minimum is .265".

It's really hard to tell without a gause (sp?) meter and a reading from a newer can to compare to.

I always thought about ordering the kit, but never did. It seemed like too much of a gimmick to really be worth it.

Here is their site:

They don't appear to be doing the comm sleeves anymore.
