TIRE TRUER's

Does anybody have any experience with the C&M tire truers?  I am hearing
the DC model tire truer is weak and stalls frequently and the AC version
is the only way to go.  Unfortunatley, it's $200 compared to $140.  Iwas
originally looking at the C&M deluxe Trackside Tire Truer ($89) but was
told that was junk.

Does anybody have any experience with a tire truer that works well and
doesn't stall and doesn't cost a fortune or am I hoping for to much?

Thank you in advance for your help.

Matt

I have the "cheap" version of the COBRA Trackside Tire Truer (bushings and
32 pitch gears).  It is noisy (due to the 32 pitch gears _and_ the
bushings instead of ball bearings), but in all honesty that doesn't matter
-- IT WORKS!  Sure, if you try to make a deep cut into long wear ***,
you can bog the _motor_, but that is just a fact of life if you are going
to use standard "car" motors.  The answer: just make smaller cuts!  I will
trade a little of my time for the significant difference in price between
my cheap version and the AC versions, etc.

My tire truer has saved me a ton of money and pain -- I have "saved" tires
that became "coned" by truing them back up nice and "flat".  I tried an
idea from "Doc" Mertes, and repaired tires that had lost a "chunk" from
the outer edge by cutting off the outer portion and then gluing on a
narrow donut piece, and truing the whole tire down to an  even diameter.  

I can custom size tires to a diameter that seems to perform best for my
cars, and I can "save" used tires -- sometimes after the tires have been
on the shelf (like over the summer while we race offroad outdoors), the
surface "skin" will not hookup very well, and I can run them through the
truer and produce a _fresh_ surface that will work like new!  I can
recycle good rims whose *** is "shot", by putting on inexpensive donuts
of whatever *** compound I want, and then truing them down.

I will probably eventually replace the gears with 48 pitch units that are
taken off of my pan cars after they show some wear, etc. (waste not, want
not).  I have also considered replacing the cheapie '05' Mabuchi motor I
am currently using with an old 550 can motor (Kyosho Mega 360) that I have
laying around, but haven't needed it yet.

Bottom line: Sure, if you have more money than you know how to spend, buy
the mega$ versions, but after two years of use, I can say that IMHO, the
COBRA Trackside Truer is worth the money.
