Paul,

Looking Good! This is gonna be real nice.  What is the OD of the
tubing where the nose gear mounts?  I have to be able to drill a
couple of holes in the washer part  as in the original.

Jerry,  hope you're doing OK.

Thanks,

Steve


I think this is what you are referring too.
I would guess something like .125" thick 4130 would be fine
for the washer part. The washer OD is 2.25 inches. The tubing
coming in must be one inch OD as it is subject to high
compressive buckling loads. A lot of the nose gear loads are
fed into the motor mount and then into the mass
of the engine. Some is taken directly by the center
of the firewall. Those tubes are 1/2 inch diameter as
they are short and buckling is not a consideration.


BTW instead of using a square flat plate to pivot the nose gear
I am using a cup design similar to the rubber bushing holders.
These are much easier to weld the required tubes and Jerry has
a bunch lying around and is very familiar with their use.

One question. What is the diameter of this tube shown in the 2nd
attached picture.

Paul,

I'll measure next time I'm over but I'm thinking it isn't more than
1/4 or 3/8 "OD.  It isn't real obvious from the photos but there are
2 pieces of square metal that  the nose gear pin rests in.  These are
what bolt to the engine mount with 2 small bolts at the back and the
one long one with a sleeve (that you asked about) in the front.  My
concern was being able to bolt the 2 pieces of metal and hence the
nose gear to the motor mount.  If you are suggesting that I don't
need all that and that the nose gear will rest directly in the cups
Jerry welds on, that's great.  He will need to adjust the width by
the thickness of the 2 squares.  Easy enough I guess but how do you
get the nose gear in there?  Maybe I need to go look at my nose gear
again.

Cheers,

Steve.

It looks like it is at least 2 inches OD. Are we talking about
the same part? It is the top part of the nose gear.
