The Airworthiness inspections I have seen do not address quality, they address if anything is unairworthy, ie, binding, loose bolts etc. They could care less about the quality. You must be able to show that you built 51% of the airplane, quality or not, plain and simple. The class rules do not state it is the supervision, it is just one person who was appointed by the group as the recipient. Be extremely careful with this rule.

I got into a bind the other night and really needed a nut plate in a place that I also really needed to glass over RIGHT NOW so I wondered if JB Weld would work. I roughed up the aluminum backing plate and poured a little JB weld around the nylock nut so that a nice little fillet was formed. I went ahead with my layup and checked it the next day. It works great! Poor man's nut plate is born. Actually, I had nutplates, just no 3/32" rivets to fasten them in with. I now have the rivets for the next time, and just for you naysayers, I don't ever PLAN to need to remove those bolts, but in case I ever have to, I won't have to tear up my ailerons to get to the nuts. Just thought I'd pass on an emergency manuever that works...

Since we bought our Audi A4 I've been frequenting http://www.a4.org . If you have time, check this place out, clicking on a4.org forums at the top of the page. The FAQ and archive search stuff is incredible. There is nothing that can't be found in this database. I'll bet if we took up a collection we could get somebody to create the same sort of database capability for us. I'll gladly throw in $50 toward such an effort. Just something to get your juices flowing. They also have a running "survey" which is about something different each week. They did one on "chipping" engines, in which several hundred people responded regarding what chips they had installed, how it performed, whether there had been maintenance problems, etc. Something like that for engine/propeller combinations, or engine and weight vs top speed, etc would be real handy for us KRNetters too. I can also say that after hanging out on a4.org's forum, you guys are the greatest! The garbage on a4 is mind numbing...

"I never understood why aircooled engines were located at the back of the vehicule. I know it might seem like a dumb question, and there must be a very good reason, but I fail to understand it." ---------------------------------------- Mark I'll go in for $50.00 but do we just sign up with an ISP for this type of service. "Costs", "Maintenance", "Ownership", Server & Disk space, developement, etc... Does Ross, you or any other member have knowledge in this type of internet service? I put the 1998 KRNET messages into a MS Word file so I could search it. It is 13 Meg in size, takes 5 minites to load, slows down my PC and is such a big pain to use it that I don't use it unless I am desperate. I think you've started another long link of discussions here. Good luck and tell me where to send my $50.00 dollars.

It's the same idea as the Great Plains rear drive unit, only it's for the EA-81. $1400 gets you a lightweight aluminum flywheel, the 3/4" thick bellhousing plate from billet aluminum, a dual-bearing shaft support from billet aluminum, a lightweight starter, and the prop shaft and hub. (I think it was included, I'll double-check when I get all their info.) You can see a similar unit at http://www.imflyn.com/images/redrive2-3.jpg only that is their planetary gear redrive. The direct drive unit looks exactly the same except the diameter at the nose of it is continued down the shaft support. This is the unit I've been waiting for, it's a lot stronger and safer than running a 6" extension on the end of the crankshaft, and it has two support bearings for the prop shaft. The fellas at ImFlyn have got the tuning of the EA-81 down pat, in fact their direct drive turbo fuel injected EA-81 is dyno'd at 165hp. The weight is 180lbs minus 12lbs for fluids and radiator. If you don't want to run a turbo, their fuel-injected DD engine dyno's at 110hp or so. Check it out for yourself at http://www.imflyn.com . Their prices seem reasonable. -Tom ---------------------------------------------------------------------- Subject: Re: instant nut plates From: ejanssen@chipsnet.com (Ed Janssen) Date: Thu, 10 Jun 1999 17:34:06 -0500 X-Message-Number: 8 I've floxed nutplates to wood before in an area that would have been impossible to use a screwdriver to put tiny screws in the "ears" and it worked very well.

There are so many things I'd like to have at my fingertips instead of trying to keep a 4 drawer file cabinet full of info I might need someday. Here's my tip in return! Made my bolt access covers for the elevator and rudder in the form of an "E" from .20 alum so I could take them off for inspection and painting. I slip a small retangular piece of alum under the fingers of the E to complete the cover. Since I have to tie them down on both sides of the control surface I got a heavy wall piece of alum tubing from the hobby shop and drilled a hole in 3 places per cover thru the control surface behind the spar. I cut a piece of tubing the width of the control surface and tapped each side 8/32, floxed it in place and hold down the cover with a 1/2" 8/32 truss head machine screw from both sides. Cheap, light and works great.

This was placed inside the spar and floxed in place before closing up the spar. My eye bolt simply screws into the bottom of the wing and the cap nut part of the assembly seals off the environment from the wing spar interior while the tee nut prevents the assembly from turning in the wood along with the flox. The hole thru the spar was sealed with varnish as well.

With the round teeth the air is expelled from the pocket very rapidly (supersonic speeds) thus creating a very noisy belt. It also better approximates the ideal hypoid gear tooth which is designed to ensure constant speed of the gears. Check a book on gear design I haven't read one in 40 years. W.G. KIRKLAND kirkland@vianet.on.ca ---------- From: Eduardo Iglesias To: KR-net users group Subject: [kr-net] wich belt Date: Tuesday, June 08, 1999 8:24 PM Since in Argentina it is almost impossible that the subsidiary of Gates informs me which belt has to use for a reduction gear of 80 hp, 270 mm among axes, 1,8 : 1 rate and with a security factor of 1,5, it is possible that some in the net has the information? Or at least, what width has a belt for that power? Here, Gates informed me that it should use a jagged belt with trapezoidal teeth 14 mm deep, when what I see in all the pictures is belts with round teeth of about 8 mm.
