In about two minutes I took it over to the airplane and wrapped it around the leading edge as a form. I held it gently with a shop rag in the jaws of a pair of pliers and covered the leading edge with a shop rag to protect it from the heat of the plexi while using it as a form. I made three as one cracked while attaching. The other two have been on there for two years now. The Bingelis books say to use your wife's oven or your barbeque at 220 - 320 degrees for 5 to 10 minutes. It shouldn't even make the house smelly. :o) Jeff Scott - Los Alamos, NM mailto:jscott.pilot@juno.com See N1213w construction and first flight at http://www.thuntek.net/~jeb/krjeff.htm ___________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

I'm not familiar with them. Rich Parker >> In WW II these gyros, which are similar in an artficial horizon operation, give two signals which are proportional to roll and pitch of the airplane. During the bombing run the bombardiers would center the target in the bombsight and keep it centered, thus in effect taking control of the airplane. An automatic control system would stabilize the airplane during that time. The gyro I have is part of that unit and is made by Honeywell. When I worked with Honeywell, a gentleman who had worked with those kind of systems loong time ago told me about the operation of 'bomb sight computers' as those gyros were called. Regarding having fun, it was a home electronic project kind of fun.

Ed, Get the Smarttool from The Tool Crib of the North at (oddly enough) http://www.toolcribofthenorth.com/oc-set.html . I paid $119 for mine, complete with the four foot "extension", and I doubt you'll find it cheaper. This thing is absolutely amazing! It beats the crap out of a water level as far as speed and ease of use goes. A water level is better only over very long distances like nose to tail or wingtip to wingtip. They read to within one tenth of a degree, which is "close enough for KR work". I'll be bringing it to the Gathering so we can find out once and for all how far the nose is pointed down during a high speed pass. I won't swear to this, but it's my understanding that a Smart Level doesn't read in tenths of a degree, but I could very well be wrong about that. I'll post a picture of this soon, as it is included in an update to Spar Construction that I'm working on for the FAQ...

This picture was made the other day while checking wing incidence at the root. You can't read it very well, but the line to the far left indicates graphically whether it's measuring vertically or horizontally, and the number to the right is 1.0 degrees. Unlike many electronic things, it's as easy to calibrate as swapping it left to right, although I haven't had to do it yet. I'd highly recommend it to anyone who's a stickler for accuracy. I'm about to get serious about aileron and flap construction. My big job at work is about to wind down enough that I can get back to 40 hours weeks again...which means 20 hours a week on the KR2S...

That's why I believe you must seal the wood(I used epoxy)in each chamber or anywhere that the wood will or could be exposed to 'Mother Nature' either directly or indirectly. In other words, when your KR is complete ALL the wood surfaces should be protected by epoxy or varnish, by having been glued, bonded or epoxied to another piece of wood, fiberglass or other materials, or by paint.

That's what I used with good success. No odors. I think I started with whatever Tony recommended in one of his books but ended up turning up the heat and after a minute or two, the plexi started to sink down around the form. When it had nearly conformed to the mold, I removed it, laid another piece of felt over the top, "wiped" it down to shape and held it until cool. Perfect fit. Make sure you use felt (I think that's right) on the mold so it doesn't scratch. The only trick was in keeping the flat piece of plexi on top of the curved mold and keeping it in the right position so it melted to the mold properly. I think I marked the cord line mark on lead edge , marked the plexi and clamped it with a small strip of wood. I'm sure you can come up with something just as good. It really wasn't difficult. Try it. Plexi is real cheep !!!!!!!!!! I think I started with 150 degrees. Then turned up the heat slowly until it melted. If it's not melting, you're not too hot but increase temp slowly enough for the plexi to come up to heat and respond. A dremel tool or similar rotary cutter is good for cutting (melting) through plexi.

There are Two units available. One reads in one tenth degree and the cheaper one reads to two tenths degree. I got the better unit a few years ago and I believe I paid $89 dollars for it. It came with a two foot rail and a very nice padded case. My case reads Wedge Innovations with phone number 1-800-SMARTLEVEL. The unit is removable from the rail and can be used solo. It is about 7 inches long. I used mine to level the boat (firewall at 90 degrees), and set the outer wing panel washout. Place a piece of quarter round trim or equivelant on the outer rib cord line, rotate to the reading you want, tack rib in place(on forward spar) and set the rear spar. Piece of cake !!!! I used it to verify my wing center section that was built with levels only and found it to be within one tenth of one degree. (I started with firewall plumb, set forward spar, clamped center section of 48 inch rib in place and used it to set the rear spar. Again, a piece of cake) You can use this method for any degree of wing incidence you want if you just redraw the spar and cord line markings on the 48 inch rib to anything you think you want. Look at your rib drawings and the fuselage drawing and this will make more sense. I have pictures and can explain what I did at the gathering. If you can't wait that long, e-mail me. When you have the KR built, you can use the Smartlevel to set/verify all the control surface deflection angles. It's great because you can be fine tuning ailerons cables from the cockpit and read the level attached to the aileron. Can you tell by now I think it's a great tool ?!!!!!!!
