Subject: Pietenpol-List: Dumb questions Pieters,I think I will not ever brag about the beautiful La weather again. It turned foul the moment I sent that letter and it remains, so I'm confined to the shop with details before me. Detail #1. For those completed Piets, did you install pulleys under the seat for rudder cables? Seems that using the holes in plywood sets up a vibration which is resonated by the wooden box fuselage. Probably wouldn't hear it in flight any way. I would like my controls more sensitive. Would those two part round plastic fairleads work in this capacity or is the angle too acute?Detail # 2. I have asked this question many times on this net without receiving any satisfactory answer. What is the DOWN incident in degrees of the crankshaft in relation to the top longeron when using an A-65? ( I may have to order some additional washers.)Detail # 3. I have a 1/4 in plywood firewall now installed (temporarily). I have a sheet of stainless steel, .025, ready to install. Being a simple-minded person I intend to face the plywood. No flanging. Any comments? If this goes well today I should be able to remount the 65 tomorrow and weather permitting, hitch the fuse to the T model and choggie on out to the airport for naked assembly Saturday. Call the FAA man, write a construction log creatively, and wait for the stuff to hit the fan.Corky in La where you wouldn't want to be today. They are even predicting sleet brrrrAnyone remember our Independence (Snow) Bowl last year?________________________________________________________________________________

I build my planes just as shown on the plans and it works fine; can't imagine any reason to change it. The holes in the wood become a fairlead.Not sure on the down thrust for the Continental, but it could be the same as for the A and the Corvair.The plans call for an 1/8 firewall bulkhead and .010 stainless or galvanize from Home Depot is good for a firewall.

Subject: Re: Pietenpol-List: Dumb questions My stainless sheet is 24 X 36 which give me enough to flange the top circle and bottom but it's flush on either side. I'll go that route.All is going well. I think I'll use nylon fairleads unfer the seat as I already have micarta fairleads in the rear where it exits.I'll just washer the hell out of the engine until I think it looks right or doesn't fly right.Corky in nasty La where I'll surprise my bride and prepare her " Les Merveilles de la Mer en Crepes" for her post birthday dinner.________________________________________________________________________________

Mike C.A question on Corky's behalf regarding the downthrust. If you were to buildthe motor mount so that the prop end of the shaft is 1" lower than if therewas no downthrust, do I assume that the rear end of the crankshaft is stillat the original point (ie where it would be if there was no downthrust)?In other words, the question is what is the point of rotation about whichyou rotate the crankshaft down? Is it the rear end of the crank? Theengine mounting bosses on the motor mount? The mounting bosses of the motormount on the fuselage at the firewall (this would give you less downthrust)?I have never had a satisfactory answer to these questions and it does changethings drastically depending on the point of rotation. An inch is not andinch someimes. Just ask Greg Cardinal and Dale Johnson.Chris---- Original Message -----

I believe that the Aeronca Spars are 3/4" stock for the main spar.----- Original Message -----

I knew there was something funny here. I went to take a peek at "Mr.Sam" Piet (nice job on the cowling, sir). Caption said it was 0-200powered. So what does the engine close-up show? A water-cooled 0-200 with all 4exhaust stacks out one side ;o) I note that the tailwheel on "Mr. Sam" looks to be the original Piet spring-type skid but with a tailwheel adapted to it. Is that correct? If so, is it the typical "shopping cart" type of resilient wheel? Oscar Zuniga Medford, Oregon mailto: taildrags(at)hotmail.com website at http://www.flysquirrel.net +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Right, the Ford engine was the original engine in Mr Sam. I flew itfor two years, then changed to an 0-200. You are right about the tailwheel. It is the tail skid adapted for awheel. I tried a shopping cart wheel, didn't last long, changed to a twoinch wheel ( I think it is two inch ) bought from an outfit in Ca & ithas never failed. I will post a pic of the tailwheel soon.
