I take it you already have a comm lathe right? This is the best article I've seen online explaining not only how to cut a comm, but also the complete motor rebuild/disassembly process. http://www.motortuningsecrets.com/tunestockmotor.html :)

unfortunatley i dont. How much do the comm lathe machines sell for a decent one anway and how hard is it for begginer with some experience to use it and cut/true comm correctly ?

Im sick of using a sports tuned I want a modifed. Last time i owned a modifed it was a very long time ago venom fireball 19T it did 2 full batt runs before i changed new brushes and that made no difference needed a com cut !

As luck would have it, the May issue of RC Car Action magazine will have a how-to on cutting comms.

A mod motor is a big leap from a sport tuned(i'm assuming you are talking about those black can tamiya motors?). You don't even set the car up the same way! How about going to rebuildable stock motors, then 19T, then mod?

The cobra lathe with diamond bit can be had for 160US new; which is the best bang for the buck lathe in my mind. Buy one of those and a couple carbide bits to practice with and when you get good, put the diamond one back on. Someone at the LHS or track will be able to show you how to use a lathe. It's not difficult but helps to have it setup for you and see it done a couple times in person.

Someone already mentioned the cobra lathe with the diamond bit for $160, and I agree that it is an excellent choice. Most lathes with a diamond bit will cost anywhere from 160-200+ Integy makes several good lathes as well, but you will need to purchase a diamond bit seperately.

That one would also be a good starting point because it comes with a motor and a battery. However, as I said before, a diamond bit is a really good idea. You could use the carbide bit to practice with first and then switch over to the diamond bit later like TEM said.

just my luck its sold out :( how easy is this thing to use for first timers ? and what other parts are needed to cut/true a motor com ?

[RC10racer89]

I would say that it is very easy to learn, although you may want to try a few practice cuts on an older comm you don't really plan on using anyway.

Depending on what type of lathe you get, you will need...
- Lathe
- Carbide Bit (most lathes include this, but a diamond bit is a must have!)
- Lathe Motor
- Battery (4 cell)
- Oil (for lubricating the V-blocks)
- Cutting Fluid http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKUF8&P=ML

Until you get a comm lathe, here's how you clean it (http://www.rc-resources.com/guides/electric_motor_maintenance.shtml), which takes you a long way in efficiency and performance.

Hmm not sure . . . This might be the same thing (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJY56&P=7). There are other kinds too, but I like the fiberglas strand ones. The one shown in the pic was made by Parma.

hmm no pic, says stick (http://www.parmapse.com/rcitem.asp?n=11050)

Leads to a dead end on their shopping cart too.

Don't know! Going to have to hunt that one down now . . .
