I have just laid up my horizontal stabilizer in the jig and was measuring out where the elevator hinges would attach when I find that the diagonal braces end up just where the outside hinges should go (4" from the end). I can get one machine screw thru the beam, but the outer one should go where the brace ends. I have some 1 3/4" stainless wood screws that I was thinking of screwing thru the beam and brace with a bit of help from T88 epoxy. Is this an acceptable practice, or is there another way of fixing the outer hinge?Rod W.in sunny West Aussie.________________________________________________________________________________Date: Wed, 9 May 2001 08:46:38 -0400 (EDT)

Hi Rod, I'm not sure about your particular hinge location, we all build a little differently, but I plan to use one of the single-eared nutplates for that outer nut. I'm thinking I'll rivet the nutplate to a longer piece of aluminum, and use that to anchor to the wood. I've also thought about just moving the whole hinge inward an inch or two to provide clearance. I'd like that hinge as far out as possible, but I don't think an inch or two is gonna make or break it!! Those are just a couple of thoughts. I saved all that hard work and just went to the fuselage.... I've got several cleanup jobs to do like that before the tailfeathers are fully finished!Good luck!Gary MeadowsSpring, Texas________________________________________________________________________________

Of course this means you'll have to drill out the holes again toremovethe excess varnish.Rodgerstill building, but much closer________________________________________________________________________________

I just finished all the parts of my tail section, and am putting themtogether for the first time. When I built them, I made sure that all of themain parts of the horizontal stabilizer were on the same center line- theleading edge, center beam, and rear main beam. I used 3/16 plywood in thecenter on the leading edge and center beam where the fin attaches, and 1/8ply on the main beam as shown on the plans. I also have 1/8 ply gusset onthe fuselage over the tailpost.Using this combination, as the plans show, I need to put a 1/8 ply spacerunder the front edge of the horizontal stab to make it level. And I need toshim up the front 3/16 ply piece on the H-stab and on the rear with a 1/8ply spacer to make the fin sit flush and level with the tailpost.Did I do something wrong? As it stands now, the fin sits high on the 3/16ply piece on the center beam of the H-stab if I don't use spacers.Thanks for the help,Al Swanson________________________________________________________________________________

Subject: Re: Pietenpol-List: Horizontal StabilizerAl my horizontal stab came out the same way. If you look at thethicknesses of the members and the spacers called for in the plans itdoesn't add up, I put the 3/16 spacer under the center beam so that thestab. sits parallel to the longerons and then filled in te space underthe leading edge . It took a hair over 1/4" spacer. Ed G. ________________________________________________________________________________

Subject: Re: Pietenpol-List: Horizontal StabilizerAl actually a 1/8" spacer under the center beam would give zero degreesof incedence. I may change mine before it's all over, When I did mine Ifigured a little positive incedence wouldn't hurt, Any comments from thegroup on this Ed G. ________________________________________________________________________________Date: Mon, 24 Sep 2001 10:34:43 -0400
