Jerry,I used T-88 & some Resorcinol, but no fancy clamping jigs. I only tried theresorcinol because I thought the dark brown color would enhance the look ofthe lamination. I found, though, that there was little difference betweenthe two, once all the sanding and finishing was done. Clamping was merelydone with several wood clamps.Clamping the struts while shaping was tried in two different ways. #1178shows a simple woodworker's vice. I used this on all the landing gearstruts.Because of the shape of the cabanes, they were a little more difficult toclamp. For those I made a jig out of 2x4. The 2x4 has two pin hole locationson one end as the cabanes are different lengths. This jig accomplishes twothings: first, you can use bolts in the holes to hold the piece down (I putmultiple washers under the strut to hold it up for shaping); secondly, thejig ensures that each strut has the fittings located exactly right.Gary BootheCool, CAPietenpolWW Corvair ConversionTail done, Fuselage on gear18 ribs done-----Original Message-----

That sure does not look like 15 ribs hanging up in the ceiling in that last photo.--------I just hope when it's my turn to reach up and touch the face of God, I don't pokehim in the eye on accident.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Thanks, Gary.I will accept your humility with a grain of salt! Your beautiful workmanship attests to your abilities!The point about laminating to avoid wood defects is well taken, I will follow suit. After computing the costs of the metal struts, I am leaning towards the wood struts! As far as the spars go, they were included in the wood I got with the Sky Scout package; they are spruce. But rather than the 1" thickness, they are 3/4", I think I will sandwich then with two pieces of 1/8" birch plywood to get the 1" (so they fit the ribs). The Hughes Hardwood place in Chico had beautiful parallel grain fir that would have made beautiful spars, cheap, too. Next time I am in Chico, I will check out the hickory. The ash seems to be really dense/heavy (stronger than hickory?). I will try to look it up.Thanks for the response. And yes, I have referenced Chris's web site and printed many photos.... but it makes my eyes and brain hurt!Ray ----- Original Message -----

God Bless America! Great pictures!ThanksJackDSMSlightly off topic, but some very cool pictures. Glad to see Edwards isholding open houses again. Very impressive show of aircraft if you can makeit.

Thanks for the pictures Gary. I think I will use T-88. I am going to laminate thegear legs too. Did you try any stain? I believe I will just varnish withoutany stain.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jerry,You're welcomed! I did not use any stain. I think most woods are beautifulwithout it! My 'varnish' is Min-Wax Urethane Spar Varnish.Gary BootheCool, CAPietenpolWW Corvair ConversionTail done, Fuselage on gear18 ribs done-----Original Message-----

This is great! All these new Piets coming along withwood struts!I had this link from a while back for Aluminum streamline tubing from Skytek. It's not them anymore!Clif"In times of change, learners inherit the earth, while the learned find themselves beautifully equipped to deal with a world that no longer exists."

My 'varnish' is ALSO Min-Wax Urethane Spar Varnish. I like the stuff. Stainingmakes me nervous. I had a pine project ruined when I stained it. The soft grainlooked "muddy".--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 24 Feb 2010 08:35:52 -0500Subject: Re: Pietenpol-List: Re: laminating struts

Subject: Re: Pietenpol-List: Aluminum strutsAllThese are done the same way I did mine in 1995. I have taken mine apart a couple of times to check for corrosion, all looks good. I got my strut material from a kit manufacturer in Kansas. Rans Aircraft I think. At the time the cost was about 1/4th the cost of making them from 4130.Jim BallewPietenpol N38BCollinsville, Ok.In a message dated 2/24/2010 8:00:01 A.M.
