My name is Sandy and I just recently purchased a Piet with a Franklin90HP. The mounting was done with EMT conduit frame bolted to thefirewall. The engine is placed about 15 to 18 inches from firewall toback of engine. I have a couple of questions. The thrust line on theengine appears to be prop down about 1" to 1.25". I notice in the plansthat for the "A" engine it show a nose low mounting. Would this applyfor all engines. Does anyone have information on mating a Franklin 90 toa Piet.My name is Sandy and I just recentlypurchased aPiet with a Franklin 90HP.

I have a Piet with the same engine. I didn't build it andhaven't looked at the mounting and plans in much detail so I can't help youmuch on that. As on yours there is a lot of room behind the engine. Thismakes the cowling very long but hasn't seemed to cause any problem withflying characteristics. Franklins are very smooth running and the 90 Hpgives nice take off and climb performance (but doesn't help much in cruise!).Jim Skinner________________________________________________________________________________

Hello Oscar,I too don't like what EAA national has been up to. I do however like what mostof the local EAA chapters are doing. I have been a tech counselor for closeto 20 years now. I do like doing that and I think that if we didn't self police,the accident statistics would reflect that. It is the main reason I am stilla member. I also learn a lot with every airplane visit I make. In fact,I probably learn more than the builder does. I usually only spend about ten minutesskimming through the magazine. Nothing very good in there for the lastfew years. Yes Oscar I agree with you and wouldn't bee a member except the Tech Counselorpart.

John I'm planning that it will need some tweaking to fit the mounts. Even witha jig my gear moved about a half inch. Instead of forcing the gear I plugged theexisting holes and moved the gear mount on the fuselage to match.

I started out with a jig and tackwelded the first set of tubes. I started having trouble with the bigger clusterwelds because I couldn't get enough heat on them. So, I removed the mountfrom the jig to weld them, thinking the jig was sinking away too much heat. WhenI tried to put it back on the jig, it didn't want to fit. After consultingwith another builder, I "coerced" the mount back on the jig with a rubber malletand now am planning on re-heating the clusters to relieve the stress. Ihope this works. I have one remaining tube to weld onto the mount and I am definitelygoing to leave it on the jig when I do that.> > Regards,> John F.> Prairie Aire 4TA0> GN-1 / Corvair 164CID> > > > ________________________________________________________________________________Subject: Re: Pietenpol-List: Re: Engine Mount

Jack,If I were modifying this jig, I'd get 4 plates which would be bolted to the uprights,matched drilled for AN5 bolts, maybe 3 to 4 inches apart prior to cuttingthe uprights. If the plates are suitably stamped or marked as to UP, or someway to identify where they go, the frame can then be bolted together, unbolted,etc., to remove the completed frames.My two cents worth...--------Tom KreinerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
