Can I use standard hardware screws to attach the leading edge or is this screwrequired to be aircraft grade? If so I can't find them in the ACS catalog.--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 14 Apr 2012 20:09:15 +0000 (UTC)

I used 8-32 stainless... Fillister head screws. I don't think they have to beanything special. --------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

John,Jack is certainly right, that you would probably not be able to remove thetemporary compression struts after the wing is trammeled, but, since this isa learning exorcise, and you still have another wing to do, you could alwaysloosen the cables and re-trammel the wing later. It=92s really a fun and easyprocess, and you will have the benefit of having it demonstrated for you. As to the construction of the tip bows=85I built mine right on top of the ribtemplate by establishing several =BD way points along the rib, install 3 or 4=94screws, and clamp the laminating strips to those screws. If it takes youmore than an hour per tip you=92re doggin=92 it!! Gary from CoolNX308MB-----Original Message-----

RE: Pietenpol-List: Cost of inspections

Without a repairman's certificate there are still cost savings. You (oranybody else) can make any repairs or modifications desired on anExperimental. Not so for a certificated aircraft. Anything morecomplicated than an oil change or changing a tire must be done by an A&P ona certificated plane.Shop around and be sure you remind them that only an A&P license is requiredto inspect a homebuilt. An IA is not required. It should be cheaper,particularly if they will let you do an "owner assisted" inspection (meaningyou do all the work under their direction and they provide a signature inthe logbook).Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

Gary,My plan shows 4 pieces of 1/4" laminated together. Did you soak and bend the plywoodto shape?

Here's where I am. I could get the temp compression stud out after mounting thewing tip with a saw if I had to. Jack, thanks for the info on tammeling. Iassume it is imperative that the points you pick on the front and rear spars mustline up from fore to aft exactly to get everything square.--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/tram ... __________

My bows are hickory, and less than 1/4", maybe even 1/8"! They're coverednow, and I don't have any close up pics. Still, I would rip 1/4", then seehow well it makes the bend...should do fine. It would probably be easiest toglue all together on the flat, then place on to the template and clamp. Atleast, that's how I did it. No soaking.Gary -----Original Message-----

Additional thought, John...I think it was Skip Gadd who talked abouttrammeling at least 3 times, during each phase of the construct. Seems likeit would be a mistake to trammel the first time after the leading andtrailing edges are on.Gary from CoolNX308MB-----Original Message-----

Correct. What you are doing is making two triangles and ensuring that theyare absolutely identical, as shown:Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

JohnI made my wing tips out of poplar. Looks like I used 7 layers. It doesn'tmatter how many you use. I made them thin enough so they did not needsoaking to bend. To form the tip I traced a wing rib on the back of my wingrib jig. I also marked where the end of the tapered end of the spars are.I then measured and drew a center line down the traced wing rib. I measuredhalf inch above and below to draw the outer lines of the wing tip. Make sureyou adjust the line so it coincides with the wing spars. I covered theboard with plastic wrap, then hammered in 10 or 15 nails along the outerlines. Trial fit the sticks. After I had it all set up, I quickly gluedeach stick with T-88, stacked them together, covered them with plastic wrapand clamped with 1-inch binder clips. After they dried I sanded off theexcess glue and rounded off the outer edges with my router but a plane orsand paper would work too.Some pictures http://westcoastpiet.com/images/Chris%2 ...
