Ok guys-- my first fusilage side is in the jig- all of my struts and braces are cut and fitted, I know I can come up with a way to fit the tailpost which will work, but there must be a proper way to do it. You obviously don't put a 1"X 1" tailpost in each side and then rip them both down the middle when you pull the posts together,or do you ?, So my question is:Do you put a 1/2X 1" in each fusilage side and glue them together when you pull the tail together or do you leave the tailpost out until after the sides are pulled together and then fit it in, and if the later is the case should you put the gussets on before you pull it together. It seems like it would be hard to get perfect alignment with out something solid holding the upper and lower longerons in alignment???????? Everything I've read says simply to pull the fusilage sides together and carefully fitt them together. If someone could let me know how they did this or how it is normally done I would appreciate it much. Ed G.

Thanks Doug Thats the way the plans made it look, but it seemed odd to put in two1"X1"s and then rip them both down to 1/2" X 1"s but I guess thats the only way to get the angle to fit right.

Just to provide a different approach, I pulled the sides together and thenput in the *single* 1x1 tailpost. There is a missing bevel of wood near thefront edge of the tailpost, but not much. Gussets went on after.steve e.-----Original Message-----

I also put the sides together first and then put in the tailpost. It workedfineand is more than strong enough. That was a brow sweater getting the twosidesaligned and straight. I used a string and measured and checked by that, butifyou look back at the archives,, someone mentioned running plumbobs to keepalignment.That idea might be good for you.Carl-----Original Message-----

"walter evans" This is one of those custom fit areas. I had gone ahead and made all of thebrackets for that area ahead of time. Scrap metal time.It turned out to be easy. Keep the aft/ lower brackets per the print. theaft / upper brackets, leave the verticle part per print, but leave thehorizontal piece long( to be cut later) and undrilled.now1.mount the aft/lower bkts2.drill up through the horz. stab. wood3. doing so you "spot" the undrilled upper bracket4. remove upper bkt. and finish drill.5. shape the end of the bracket to look good"This way it doesn't matter how wide the tailpost is. "To shoot the horz stab for being square and even, I put an aircraft nail inthe top of the turtledeck, behind the rear seat. and had a measuring wireor tape ( string stretches too much) hooked to the nail. This way it waseasy to swing back and forth to get the rear tips of the horz stab exact,before drilling to the fuse.walt-----------------------------------------------------Click here for Free Video!!http://www.gohip.com/freevideo/----- Original Message -----

Concerning your query; Yes, thats the way I did it.Put a triangular 1" thick filler block, I think I used white ash,sandwiched between two 1/8" ply gussets then bolted a 12 ga 4130 strap tothat and atttached the cable shackle to that. Used 1/8 cable to theshoulder harness fitting. This is between the top longerons. This gives agood cable angle and the strongest anchor point.----- Original Message -----
