Hi all here are some views on recent building questions.Re gluing ply sides on fuse, strongly recommend leaving these off tillthe very last; also leave off the firewall ply.Suggest screwing on a dummy bulkhead, in fact if you make this verysquare & accurate it will keep everything square up front while gluingsides together.I have had a strong recommendation not to cover any structure witheither ply or fabric until the A/c is assembled, rigged, fuel is in tank& you are ready to fly.This will enable you to check all control runs, bracing cableselectrical wiring, even a check for fuel leaks under tanks & plumbingetc.You may find that some adjusting or modifying is reqd in order to clearstructure from something that moves, this essential step could be verydifficult if the structure is covered.Then dismantle,glue on sides & fire wall, cover, & paint.Re questions on gluing on ribs to spars,suggest making an accuratetemplate out of ply or wood to the exact inside measurement of the ribverticals.Lightly sand the spar until the template slides on with slight friction,Slide on ribs to within =BD inch of final position, coat spar with gluethen move rib to correct position, if you use a liquid type of glue likeWest Systems 105 you can wick in more glue.Some questions re alignment of tail structure, suggest having anaccurate centre line on all members; make sure that all is in line; gluethen taper after it is set.If you find the routed Tee beams difficult then consider making them outof two pieces glued together.I found that the diagonal beam on the tail plane fouled the nut on theouter elevator hinge, I had to relocate the beam to clear this nut bymoving it at the tip end.I am just over half way with my Piet & have asked a thousand questionsof others.I have leaned on Peter Johnson=92s Web heavily & have followed his stepsclosely, it really is just fantastic see HYPERLINK"http://www.cpc-world.com/"www.cpc-world.comCheers & Good LuckGraham Hewitt the 79 year old ex DC3 driver17/11/2007 2:55 PM________________________________________________________________________________Date: Sun, 18 Nov 2007 03:54:30 +0000 (UTC)

Subject: Re: Pietenpol-List: Question about a Pete Bower comment from an old articleI have not read Mr. Bowers piece so cannot comment on it. I do have a short fuselage Piet with a Corvair engine. I was told I would have a w/b problem so I retained the blower fan, cast iron manefolds and the original alternatorso my engine is probably a little heavier than need be. In order to to get the w/b in range with my weight, I still had to move the fusegage about 4 in.forward (wing 4in. back). The empty weight came out to 625 lbs. and it fliesgreat.
