I see that you are getting questions about the wheels on my plane. The wheels are 5"
Azusalite nylon wheels with 4.10x3.50 x5 tires and tubes. The brake portion of the wheels
consists of AZ-2211 Azusa drums, AZ-2259A Azusa platforms, AZ-2255 Azusa band brake
disks and a cable set from Tracy Obrien. Since the diameter of this tire is only 12" versus
the 20" on Leondard's drawings for his wheel, the gear was extended 4" so that the final
angle was the same. Note also that I did not use the gear springs but just used a
continuous piece of steel tubing and made it a hard gear. I put 192 hours on a Fisher Avenger using this same type hard gear (412 landings) without incident. Other than these two changes, the gear is as shown on Leonard's drawings, .049" steel except that the
5/8" axles are .058" wall.

I now have 62 T/O's and Landings on my LEU gear and really checked it close after
reading about how Harold Pope bent both gears just doing taxi tests. I found a 1/8"
bow in my right gear. I took it to a friend who is a structural engineer and he designed
a light, strong and easy fix. Take a piece of .040" 4130 steel 2" wide and bend a
9/16" angle on each edge. This leaves a 5/8" width. Slip this over the gear tube and
weld it along the center of the tube on each side. Both gear legs add only 1# and
he says it is 3 times the original strength. I have attached a picture showing how
the top of the channel does not contact the gear tube as he says this is how the
added strength is obtained. Some other builders might consider this during initial
construction.

There are metal elbows inside those big rubber boots - no flow director in the pipe "Y" at the carb outlet... It's a Harley carb with altitude compensation circuitry... Carb heat an open item... Engine runs strong...
This is the finished engine installation... Chester Thomas reports that Doug has flown June 2004 - see driveway rollout next:
They look good in Red and White!.. Notice streamlined lift struts and two wing tanks holding 3 gallons each...

Hey Leonard, Take a look at this jig!...
E-mail group: Thought I'd show a picture of my compressor used to preload my springs. Made from scrap 1/4" plate and 3/8" all thread. There is a piece of split 7/8" tube spacer allowing tack welding through its gap (on the left painted white for clarity). I also added a welded spring travel stop so that the lower 1/2" tube could be removed and reinstalled without having to recompress the spring. (painted white on the right) It also takes some of the stress off of the bolt or pin as the bolt does not have to act as a rebound stop. I plan to cut off the extra 3/4" tube to save a little weight.
