Also can anyone advise me about removing or painting over power coating? I think my springs are power coated and they may not match the color scheme planned.

It has the springs, tubing, washers etc for a turnkey weld it your self shock kit. Leon S.

I am going to use the plans except for mating Taylorcraft axles to the landing gear because they were a gift and I can't afford to turn them down. In one of the older BPA Newsletters were the plans for a split axle gear using the die springs. The tubing sizes were given and I went over to Shapiro and bought all the tubing for the die spring shock set up for $15 last saturday. Hope to have less than $135 total in gear when done. Not that I am trying to skimp, but if you go to Shapiro in person on saturday morning, the guys in the cutting rooms know you and make you a great deal.

From: cat_designs@juno.com --> Pietenpol-List message posted by: cat_designs@juno.com Tom, I have sat in my seat numerous times, honestly I am test fitting not just pretending I am flying and you have to make the airplane to get the fit just right, and I have had no problems with it braking but I am a light weight (160 pounds), I think you could split it apart and glue it back together if it fits together well. If not take it out and put in a new piece. I found the best way to remove things like this is to use a SHARP chisel, a 1" chisel is my preferred weapon of choice. Use a small saw to to make a cut almost all the way through the piece near both ends. You don't have to be to close say 1/4" away. Using the chisel take the bulk of it off in large chunks but as you get closer the the glue line slow down and take smaller slivers of wood. Now as you get close to the ply sharpen your chisel again. Lay the back of the chisel flat on the wood you are removing, at about a 20 degree angle. Now push it by hand don't use a hammer. You should be taking little chunks of wood off, if not raise the angle slightly. When you get down to nothing but glue you can usually scrape it off with a single edge razor blade, I like the heavy duty ones for the razor blade knifes used for cutting drywall. Also round the tips off using you grinder so you don't gouge the plywood. This works great for cured T-88 and I would guess it would work on other types of glue. As for reinforcing the seat you might be able to put a support running left to right under the 4 seat frame pieces at about mid span. support this on the ends from the lower longerons. This may be a problem with hitting the control cables though. Perhaps this one support was higher then the rest and took the full load. If this true the new one should be ok because with the seat bottom installed it will line up better. Just my opinion, for what ever that's worth Chris Sacramento, CA --- "Brants" wrote: --> Pietenpol-List message posted by: "Brants" Wondering if anyone has ever had the experience of their pilot seat frame members cracking. I'm not THAT fat (200 lbs)... I just installed the pilot seat last week and I was sitting in it trying to get a feel for how the front seatback would be layed out. Each time I sat, I heard a small creak. I thought maybe it was the workbench but I figured I'd look around. Found out it was one of the inner structural members of the seat. Didn't crack at the glue line (proof that the glue is stronger than the wood) it split about 1/8" from the glue line, right down the grain. What I think may be the cause is that there is so little support for the wood at that point, other than the glue on the ply and end grain. So, If I remove the member, what's a good way to do it without ruining the seat. I thought I might just pry the split section appart, apply some epoxy in the crack and clamp together. Then add a plywood gusset beneath the back frame member and the 4 other members, tying them all together. Any opions here? Also, wondering if others are using T88 as filler on occassion where small gaps in joints appear or where plywood gussets are held down. I've come accross a few situations where the plywood, although I staple it down, leaves a small gap (1/16" or so). Wondering if filling this void is acceptable. And lastly, any people here fly around the West Virginia mountainous areas? I'm planning a trip later in the summer and could use some feedback on my plans. If so, contact me directly at tmbrant@usfamily.net Thanks! Tom Brant Brooklyn Park, MN The best thing to hit the internet in years - Juno SpeedBand!

A-65 powered 31' oversize wingspan with steel tube fuselage and monocoupe tail. cruise and flat out are basically the same. It climbs at 2125 rpm, flat out is 2250 rpm at 71-73 mph, and throttling back to 2200 seems to make no difference to the speed. Climb is 300-350 fpm and I've found best climb around 58-64 mph. It's wonderful to fly in the morning or evening, and during the thermals of the day a handful. I recently went flying about one hour after a strong system passed over with more cumulus forming. And found it to be a white knuckle, attention getter. 200 ft altitude bounces both wats were the norm. But the flying in smooth calm air makes it all worth it. I also find that landing the Piet well is a challenge. If I come in without power, the flair must be perfect. Otherwise it will slow down instantaneously and drop. I usually fly final at 55-60 mph with 1500 rpm right to the flair. Once I am level in the flair power is removed fast or slow depending on how high the flair was and the stick pulled back. I have inadvertently done some nice wheel landings by not pulling back on the stick fast enough and it just rolled out on the mains.
