I'm getting ready to make/buy hinges for the elevator and rudder. I waswondering if anyone had any suggestions before I spent the time buildingthe 36 or so parts.Also did everyone use #8 aircraft hardware with a washer to hold theseon?Did anybody just make the control hornes out of heavier gauge acaluminum instead of the airdynamic weldment the plans show?thanks,Greg Yotz________________________________________________________________________________

>I'm getting ready to make/buy hinges for the elevator and rudder.

Soundssoft but I've seen them with no wear after hundreds of hours. Made minethe hard way. Info on Kapler can be found on the BPAN website byGrant MacLaren. >Also did everyone use #8 aircraft hardware with a washer to hold these>on?I recessed my tailfeather edges with a router very carefully to 'sink' thehinges in flush with the surface then used 10-32 machine screws witha 'pan head' phillips style. ps-you need to cut holes in some gusettsto get the nuts on.>Did anybody just make the control hornes out of heavier gauge ac>aluminum instead of the airdynamic weldment the plans show?>This has been done w/ heavier gauge 4130 Steel, but have not seenthem in alum. The thin steel used to form the two-piece control hornswas easier to work than I predicted- but welding is touchy- if you canmake them 2 piece and have them tig welded by a good tig welder-makesa nice clean edge. (ps- those babies are light as can be and SUPERstrong. Bernie was no slacker. Mike C. >thanks,>>Greg Yotz>>________________________________________________________________________________

Hi Greg: Another variation on the theme: Consider using two AN43B-13 eyeboltsand one AN23-10 clevis bolt, with the necessary washers, castle nuts andcotter-pins at each hinge location, slightly recessed like Mike mentioned.Very simple, light, and very strong.Warren________________________________________________________________________________

Vi Kappler has a complete set of hinges for about $27.00, (last time Ichecked). I bought a set, and they are great, just needing a little file workfor perfect fit. Saves hours and hours and hours....Vi is listed on the BPAN page. Good luck! Don C.________________________________________________________________________________

I used some 1-3/8 or so streamline tubing (steel) to form my rudder andelevator horns. They're a little heavy, but Strong! Don C.________________________________________________________________________________

Micheal,I haven't filed them to final profile, yet, but am planning on about 30degrees' travel. The plans don't show that so I'm guessing. Bigdisappointment was no Piets at Evergreen Fly-in last week-end. Where were allyou North-West guys?Don C.________________________________________________________________________________

Same price I paid at Brodhead this year! They come with cotter pins &with the mounting holes countersunk.Don, how much file work did you do -- enough to let the hinge rotate 30degrees each way ??Michael C.Pretty Prairie, KS> Vi Kappler has a complete set of hinges for about $27.00, (last timeI> checked).
