He sounds like he's kidding but Ive often wondered if it would be possible to do the "gun drill each lobe of the rotors, balance em," part. Is there any reason this wouldn't be a good idea?

Seems like it would eat a lot less HP to spin lighter rotors... I'm all for reducing rotating mass.

Ron I used to rebuild them at the machine shop I worked at so if you have any questions let me know. The bearings are the same as the small nose bearing and the seals are sometimes hard to find. We had them custom made and looked exactly like the OE seals but there are quite a few places out there selling them if you dig around. They has some crap setup for pressing them apart so where is what I did to make life easy...... I took a bad core housing and sawed it in half- right where the rotors end inside the housing and then I welded on two 1" blocks to raise it up . Drop in the rotors and use a pin slightly smaller than the rotor shaft and press away! Makes taking them apart a snap and is much safer/faster that messing around with a puller or blocks and a press as I have had them kick out under load before and its not fun!

^With Daves advice, I made a jig as well to press the gears off.

There isn't much to the rotor assembly, and I too, and working on offering a rebuild service for them as well. This service should not cost no $350.00 to $400.00 as some are charging, but are they really doing any?

My rebuild will cover the rotors being recoated, bearings, and seals as well. The seals are a goofy sized one I have heard too, but I have a place locally that I can get them through in a large quantity no problem.

The rotors are not Teflon coated, never have been.

Once everything is reassembled, they will be rebalanced as well, then ready to rock and roll.

To answer the question above, yes, in a normal good set of rotors there is a small amount of play on the rotors from side to side, and once installed in the case, end to end. As they heat up, this gets smaller, but does not rub.
