It would be much better to stay on top of your top layers of bidirectional cloth. Then simply add a couple of washers or a spacer onto the axle before you put the wheel on and it will give you clearance from the lower bolt heads. This is what I did and it works very well.

This is the way I did it on my KR. Worked out great. -Donald 38TF "Rod Kelso" on 03/02/99 10:46:04 AM Please respond to "KR-net users group" To: "KR-net users group" cc: (bcc: Donald Norris/AUS/NIC) Subject: [kr-net] Brake rotor Netters, Why couldnt you just space the wheel hub out a little with a spacer and not worry about grinding the bolt ( like Dr Deans picture page ) , or relocate the bolts, or counter sink them.

The head of the outermost bolt is fairly close to the brake disk on mine, but as long as it doesn't touch it, I don't think it matters. As for aerodynamic cleanliness, that whole section should be faired anyway (unlike mine so far). That really makes it a non issue.

Besides most of the shear load is applied to the bolt on the other side of the leg. Like Jeff says, if it misses the drum at all its a non-issue but it would sure look much more "aviation" if the proper hardware was used. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290 (Sky Pig 290) ,..Still Building the Cowling... mailto:mikemims@home.com http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo Ca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Trike conversion From: SkyHawk11@aol.com Date: Tue, 2 Mar 1999 22:18:36 EST X-Message-Number: 7 BOBBY SMITH JUST FINISHED A KR2S WITH NOSE GEAR CONV LOOKS GREAT WAITING FOR FAA INSPECT TOMORROW BEFORE FLYING HAS COMPLETED HIGH SPEED TAXIES N808BS BROWNWOOD TEXAS ---------------------------------------------------------------------- Subject: Re: Diehl main gear From: Douglas Dorfmeier Date: Tue, 02 Mar 1999 19:28:48 -0800 X-Message-Number: 8 Mike Mims wrote: > > Hey I was surfing the web tonight and I remembered something I talked > with Larry about a few weeks ago.

I will be installing the Diehl trigear. It would be nice to raise all the gear about 6 inches. How about doing some kind of extension to both the main gear and the nose gear. Maybe this could be an alluminum bar added to the Diehl Main Gear and having an extension welded to the nose gear? ---------------------------------------------------------------------- Subject: Re: Diehl main gear From: jscott.pilot@juno.com Date: Tue, 2 Mar 1999 21:04:27 -0800 X-Message-Number: 9 On Tue, 02 Mar 1999 19:28:48 -0800 Douglas Dorfmeier writes: >Mike Mims wrote: > >Interesting post.

If you ask Dan Diehl about this he will tell you that the aluminum castings he builds for the wings are not designed to carry the additional torque applied by the additional gear length. I have one of two sets of gear legs Dan sold that are 6" longer that he usually sells. The other set is not flying yet, and Dan won't cut them long any more. Dan approached me at the KR Gathering and advised me to cut down my gear legs due to his concerns about the torque on the aluminum castings. When I declined, his advice was, "Then make good landings." If you ever see my bird sitting on the ground, you will notice the bow in the gear legs that are not present in most Deihl gear legs. This is also due to the additional torque applied by six inch longer gear legs. When the plane was finished, I found that I had to have shims machined to bring the camber back into place on the landing gear due the the bow in the gear legs. Now, if you were to design your own mounts for the gear and use the thicker material from the Grumman Yankee gear legs, you might have a pretty nice setup. I do like the taller gear legs on my bird.

According to my friend Gene there was an almost immediate forward stall and then straight down (nose). He braced himself for death and just before impact the engine must have restarted from the look of the prop (both sides are broke close to the center in the thick part) and with full aft stick the nose just lifted enough to pancake in a little nose down. His Diehl fiberglass legs both broke about half way wheels into bottom of center section and left outer wing bottom. The aluminum fittings that attach to the spar was not damaged. I was really surprised to see these fittings undamaged. I thought this may help some of you decide on the strength of the fittings.
