Ahh yes the donut holes and coffee.- I really do miss Vance and his ideas
and help.- Not only inovative but the best of friends

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 th
e 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 pr
essing. You can search around for some sort of scrap that would work.- Yo
u 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 so
me 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 tha
t 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 an
d 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 t
hat 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 secti
on of thick wall box section tube and put it over the end of the gear and p
ull it into the right angle.- Use scraps of metal and wood to pad and for
ce the bend where you want it.
I also miss having Vance around.- I really enjoyed taking shop or anythin
g with him.- The best part of the day at High Tec was when Vance would st
op by for some engineering bsing and bring donut holes.- I am sure Rich a
lso misses his help, insight and company.

Hi OC,
I don't think shims will work with this large of an angle since the bolt ho
les will not line up.- What I would need is new axles machined with 7 deg
rees of negative camber, but I think the best thing to do is just to get th
e gear bent correctly.
I should give the grove guy a call and see what options he comes up with.
- I did email grove to ask how much it would be to adjust the camber and
they want $300 which seems insane for what would probably be 30 minutes of
work for them at most.- That was just from a sales drone though, maybe Ro
bbie wouuld be more reasonable.
Thanks,
Scott

Hello Scott, If you are determined to bend your own I bet you could rig thi
s to do the bending:

I still think that it is worth a phone call to Robbie Grove to get his inpu
t. 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 g
et 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 bl
ock 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 m
uch. 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

Hi All
Started to mount the front landing gear to-day but it seems to result in
a very high "nose up" attitude. Is there a spec for the angle that the
fuselage should be while on the gear?
Thanks
Mike
