Hello Scott, I am pretty sure that it was not Grove. When I converted my KIS
TR-1 from Matco to Grove wheels and brakes I had to make extensive grinding
changes to the bottom end of the gear to make the Grove brake assembly fit.
Both Grove and Aircraft Spruce will sell you axle shims that will permit you
to change the camber. See here:
http://www.aircraftspruce.com/catalog/lgpages/axleShims.php
http://www.groveaircraft.com/accessories.html
Seven degrees sounds like a lot to change all at once, but you can stack the
shims to get varying results. Playing around with the shims would be a bit
less drastic than pulling and bending the gear.
Why don't you call Robbie Grove at 1-619-562-1268 and discuss the situation
with him -- he has always been very helpful.

Hello all,
Does anyone remember who made the landing gear? Was is Grove down in San
Diego?
My landing gear was not bent correctly originally and I'm probably going to
pull it off and have it adjusted. Right now the camber is off vertical by
about 7 degrees and its wearing the inner part of the tire really fast.

The gear were made by several suppliers untill Lyle started doing them.-
He did the most amount.- Possibly you could just find someone to bend it
on a press for adjustment or use some shims like OC suggested.

Shims will probably be cheaper than a new gear. Even with a new gear, you
may still need a shim or two to get the alignment right in both toe and
camber.

Hello Scott,
When I bought my TR1 with the bent gear, Vance straightened it using a press.
The gear yields at under 4 Gs so can be bent with about 3 tons depending on geometry.
You should be able to find one around to use. If not Harbor Freight
will have their 12 ton press for $89.99 with a coupon from 28 to 31 Oct.

Hi OC,
-
The problem with shims is that that the bolt holes will not align.- It wo
uld work with 1/2 a degree or one, but not seven.- They are way off.- I
have some 5 degree shims I got from summit racing, but the bolt holes will
never be right.
-
I've gone round and round with this in my head and I think just pulling the
gear and bending it to the correct angle is the cleanest thing to do.-

I'm not looking at getter a whole new gear, just increasing the bends in th

7 degrees is way too much to shim.

Hey Scott,
Vance did not anneal before bending or reheat treat after bending. I do not think
the aluminum will need to be reheat treated.
I am not sure how Vance rebent my gear. I kind of assume he used a big V block
of sorts and then pressed the corner he wanted sharper into the V. If I recall
correctly his press was maybe 20 tons but he said it did not take much. The
larger the V block the less the force required. Have you seen the large hydraulic
pipe benders at Harbor Freight? They use rollers instead of a V block
but the idea is the same.

Hello Scott, If you are determined to bend your own I bet you could rig this
to do the bending:
http://www.harborfreight.com/12-ton-hydraulic-pipe-bender-32888.html
I still think that it is worth a phone call to Robbie Grove to get his
input. He may even be able to provide you some undrilled, one piece shims
that could solve your problems. Why not pick his brain -- even if you decide
to bend the gear yourself he may have some pertinent advice.

Hi Scott,
If the gear leg will fit between the plates then the pipe bender may be the best
way to go. The V block does not need to be an actual V. Only the top corners
of the V are actually used. So any two parallel supports 8 inches apart would
work. But keep in mind they are forced apart when pressing. You can search
around for some sort of scrap that would work. You could also get two plates,
drill two holes in each and put in two pins to support the gear similar to
the pipe bender. Or you can cut and weld some metal together. Depending, you
may also want to put a plate along the gear so you do not scratch the gear.
You could also search around your area for a iron or metal working shop that is
set up to bend things. I know of a good one in Zhuhai that would do it for 10
yuan. If you brought it here I could also help you out.
Another idea is bolt the gear to the floor. Then get or make a strong and long
lever arm with fork at the end. Put the fork over the end of the gear and give
it a careful yank. A quick rough calculation makes me think that you only need
about 1500 ft-lbs to bend it. So given your 200 lbs of weight you would need
about an 8 foot lever arm.
Or if you were a real hacker like me, find some guard rail or other closely spaced
posts and put the gear between them to hold it. Then get a section of thick
wall box section tube and put it over the end of the gear and pull it into
the right angle. Use scraps of metal and wood to pad and force the bend where
you want it.
I also miss having Vance around. I really enjoyed taking shop or anything with
him. The best part of the day at High Tec was when Vance would stop by for some
engineering bsing and bring donut holes. I am sure Rich also misses his help,
insight and company.

I still think that it is worth a phone call to Robbie Grove to get his input. He
may even be able to provide you some undrilled, one piece shims that could solve
your problems. Why not pick his brain -- even if you decide to bend the gear
yourself he may have some pertinent advice.
Please read again what 'OC' Baker Says.

Hey Mark,
Wouldn't it be nice if Vance were still around.
So I would press the bend of the gear down into the V block? Were could I get a
V block or would I have to make one?

Hey Scott,
Vance did not anneal before bending or reheat treat after bending. I do not think
the aluminum will need to be reheat treated.
I am not sure how Vance rebent my gear. I kind of assume he used a big V block
of sorts and then pressed the corner he wanted sharper into the V. If I recall
correctly his press was maybe 20 tons but he said it did not take much. The larger
the V block the less the force required. Have you seen the large hydraulic
pipe benders at Harbor Freight? They use rollers instead of a V block but the
idea is the

'OC' and ALL,
I just wanted to comment on my Matco brakes. After 10 years of less than
satisfactory braking on my TR-1 I now have them working properly.
I met George Happ (Matco) at his booth at OSH this year and got to try
his brake simulator that demonstrated the pressure to the brake calipers
with the master cylinder attached at different locations on the pedals.
The difference in caliper pressure was dramatic with just a small change
in the position of the master cylinder on the brake pedal. He had
pressure gauges attached to the lines so you could see the pressure
applied to the calipers as you pushed the pedals. I had tested my
pressure and found that with normal brake pressure I was generating
200/250 lbs., medium pressure 400/450 lbs., hard pressure 600/650 lbs.
With the kit brake pedals, using the hole supplied, you don't produce
enough pressure, with a normal push, which produces a lot of heat and
wear and poor braking. I did melt the end of the plastic line from all
the heat. I was able to drill a new hole in the pedals about 1/2" closer
to the ruder bar and still have clearance for the master cylinder shaft
to fully extend. The result was dramatic and I now have satisfactory
brakes. You need the 600 lbs. for efficient braking.
FWIW,
Tim

My brake power is less than ideal with the matcos too.- I ordered the mas
ter cylinder kit from them that reduces the master cylinder bore diameter s
ignificantly so you generate more pressure with a given force on the pedal.
- I think that will have the same effect, but I'll report back when I ins
tall the kit.

Scott,
I added that Intensifier kit last year and it helped a little. I had
also lengthened the rudder pedal per the recommend length. If you find
that you still want more pressure after adding the kit then moving the
fulcrum point will do the trick. Of course you will have ready access to
the pedals when you remove the master cylinders to install the kit. But
if you do both at the same time you won't know which had the most
effect.
Have you finished your phase 1 testing? I would be interested in your
assessment.
Tim
