I love radial engines, but I am not a big fan of the- Rotecs. I do not know much about them, but I do know tha t they have an internal gear reduction unit. This unit seems to give them a bit of a whine which I do not care for.- Again, in my opinion, they look a bit large for the Pietenpol as well, both in the number of cylinders and the actual diameter of the engine. - I am looking for a more vintage radial for my Piet., so if anyone ever hear s of such a thing for sale, please let me know! - If Rotec is listening...if they make a 5 cylinder, 90 HP, non whining radia l cheap enough for most home builders to afford...they would make a killing ! ________________________________ Message 2 _____________________________________ Time: 07:45:35 AM PST US From: Michael Perez Subject: Pietenpol-List: Epoxy smudges with varnish Curious, is it necessary to sand off any epoxy smudges prior to varnish? I wonder if the varnish covers them up nicely or do the smudges show through? - Thanks. ________________________________ Message 3 _____________________________________ Time: 08:02:29 AM PST US From: Michael Perez Subject: Re: Pietenpol-List: horiz stab and elevator Well, you will pay a small weight penilty if you use solid 1" spruce on the ends as opposed to the normal "routed" type. One way to get that same shap e is to epoxy two pieces together. (Picture attached)- The other picture is of the tapered sides for the elevators. I modified my elevators some, so the taper is more pronounced. - Looking ahead to covering... if you use the solid 1" spruce, that wide 1" f lat will be visable under the fabric. You'll see that 1" border on those si des, where as if routed it is 1/4". - - ________________________________ Message 4 _____________________________________ Time: 08:41:02 AM PST US From: Dan Yocum Subject: Re: Pietenpol-List: Epoxy smudges with varnish The epoxy will seal the wood just as well, if not better, than varnish. So, unless the part you're varnishing is visible I don't see the need to sand the epoxy off prior to sealing it with varnish. Now, if the part you're varnishing is visible, i.e., in the cockpit, the varnish may not adhere to the epoxy nicely and it may not look as nice. I'd probably sand or scrape (with a sharp paint scraper) the epoxy off prior to varnishing.

It is a mudy mess! I hope to have both the Piet, and the hanger done before the Ohio Piet "Party", on june 19. Putting up a pole barn without help is making me wish I was still in my 20's, it hurts more now than it used to. At least I haven't missed any good flying weather since last week, I think I will go out and play in the mud now, happy flying. "You gotta be tough, when you're dumb."

How are you going to "attach" the trim cables to the elevator bell crank?

The trim cables will go off to the left, so they shouldn't foul the control cables. I'm open to suggestions, though. > >Jeff, > >On 05/11/2010 06:27 PM, Jeff Boatright wrote: >> >>Hey Dan, >> >>I didn't describe the plan well.

From: "bcolleran" So I started today on the horizontal stab as the first piece that I am building. I have about enough room to slide a piece of paper in the tightness of my fit between my diagonal braces. Is that too much or will the t-88 expand and make up for it?

That will be just fine. You do not want a starved T-88 joint any way.

From: "Bill Church" Probably just getting picky here, but T-88 will not expand to fill the gap. It will bridge small gaps, but it does not expand. If the gaps are too large, and you're using straight T-88 (no fillers) you will come back later to find that some of the glue has run out of the joint. But in your case, with a gap the thickness of a piece of paper, you shouldn't have any problem. That polyurethane Gorilla Glue stuff does expand. But I wouldn't use that glue on my airplane. It isn't really strong enough for aircraft structural applications.
