| Subject: | Main gear alignment |
Hi guys,
For those interested in the method I used for aligning the main gear, I submit
these pics. Two 1/2" diameter aluminum rods were inserted into the axle sockets
such that they met in the middle of the fuselage and were aligned with each
other. This told me that the wheels were parallel with each other. Then, deciding
how much toe-in I wanted, and using the magical math of trigonometry, I offset
one gear to the length of the short leg of the triangle. The gear tube was
drilled and the other gear was turned so that the 1/2" rod ends were together
again, and the other gear leg was then drilled. It's easier done than explained.
More than one way to skin a cat. Hope this helps.

| Subject: | Main gear alignment |
Hi guys,
Here's my method for aligning the main gear. Of course, it helps to have a machinist
buddy to make my drilling jig(s).
First, two 1/2" aluminum tubes are inserted in the axles so that they meet in the
middle. That tells me that the wheels are parallel with the fuselage center
line. Then using trigonometry to determine and rotate the gear to match the short
leg of the triangle, twist one gear leg to the desired toe-in (I used 1 1/2
degrees toe-in). The gear socket is then drilled, preferably using a drill
jig. Once that's done, twist the other gear leg so that the end of the aluminum
rods again meet and drill the second leg. Easy peachy, lemon squeezy.
Hope this helps.

| Subject: | Gear socket drilling jig. |
Guys,
Sorry that the basic same message got sent twice, that was my boo boo. I have AutoCAD
drawings of the drilling jigs for both the main gear and the nose gear
sockets. If you have access to ACAD, I can forward the drawings, for those that
want it, or contact me offline and send me a SASE and I'll send a copy.

Here's a couple or three (or four) canopy fitting pics for your review and consideration.
Enjoy.

| Subject: | Oil return bottle |
Guys,
Some mods that I made to the oil return bottle. The fiberglass top and bottom were
removed and replaced with 1/16" aluminum. The internal baffle was also welded
to the new top. Just because, no other reason. Looks more better, less worse.

Guys,
A couple more pics of the main and nose drill jigs. The hardened steel guide is
the only way to go. Enjoy.

I personally don't like to use plain bolts on moving surfaces. Soooo, I used drilled
head bolts. Of course, I had to drill the assembly someplace to attach the
safety wire. Gives me peace of mind.

| Subject: | Rudder cable attach |
Guys,
I had a little issue with the way the rudder cables were attached at the bell crank
behind the panel. Basically, the cable needed to be sandwiched between two
parts (like a hinge.) The way it's designed puts a twisting load on the pin
or bolt. Not a good thing, IMHO.
My solution is to make tabs from 4130 .062" steel and rivet them in place. Voila!
the cable no longer puts an asymmetrical load on the pin. Smart them Chinese,
huh?

Group,
A couple of early pics of my extended wing tip mods. Modifications are now complete
and all of the parts behind the firewall are now ready for primer and paint.
More pics coming....

| Subject: | More wing tip mod pics |
guys,
Since I decided to extend the ailerons by 10", this meant that the tips also would
need a "little" work (yeah, right! a little). The rear spar had to be extended
as well. I'm very glad that's over, it was a bunch of work!
