comm truing

[tc3guy]

What exactly are the benefits of commutator truing?

[FastDad]

Your motor runs better, faster, longer, and
you will not replace it as often. Just ensure you change the brushes each time it is
trued.

Also, be sure to do it & change brushes at a regular basis. If you're using high silver content brushes(like those for the Trinity P2K or Reedy Rage motors), then you need to change them fairly frequently, maybe about every 4-10 runs. If you try to run those kinds of brushes for too long, you will actually do more wear to the comm than if you change them more frequently & retrue the comm often. I've tried doing it every 8-10 runs, & now do it every 4-5 runs, & doing it more often reduces the amount of material you have to remove from the comm each time(& also adds up over time, I have less overall comm wear from doing it every week than by doing it every other week, including the material removed using the comm lathe)..... http://www.rccaraction.com/ubb/smile.gif

Anybody know about any cheap lathes that are under $160 but id like it to work well. Im not up for using a crappy lathe.

[stormperson]

i use the cobra pro 2000 lathe, and i use the diamond bit, which is a must, well sorta. but its a very good idea. i think stormer sells em for around 160, however get a normal bit which are under 10 to practice with, that way you dont wreck the diamond one. which is alot more.

I use a Xipp mod lathe, it has many nice features and is available through integy @ http://www.integy.com/cgi-bin/webc.cgi/st_prod.html?p_prodid=X-MODLATHE&sid=1b4xXH-4
it is a nice mod motor lathe as you can see it comes with ball bearing V blocks, comm down stop, and a pre-wired swich. http://www.rccaraction.com/ubb/smile.gif

I'll be truing stock and modified motors is there a lathe that can do this?

[B3 Bomb]

There is a Hudy lathe that can do both stock and mod, but what i did is I ditched all of my non rebuildable stock motors and bought rebulidable stock motors and mods.

[Nairb]

What B3 Bomb is implying is that the new rebuildable stock motors (P2K, GM3, etc) can be taken apart and, therefore, can be trued with a regular Mod lathe. So as long as you have newer stock motors, you'll be fine with a mod lathe.

Is Trinity's Tru-Lathe 2 any good because it is very cheap?
