Brake Parts cleaner.... get a spray can from your autoparts store and use it to clean your hands and such after mixing up a batch. Cuts right through and cleans perfectly! Make sure you wash your hands with soap afterwards to rinse off the brake cleaner.

Ocassionally I have to revert to my old tried and true paint and varnish remover to get these old paws clean. My bride has made some comments while sitting in the moonlight that my hands aren't as nice and soft as they should be. Could that be the problem?

I have made a point of wearing a good fitting pair of surgical latex gloves, I get these from a local boat builder. For my tools, I wipe the excess off with shop towels and then wipe them down with a cloth and some paint & varnish remover. I use small mixing cups for the glue so I just throw them away along with the mixing sticks ( popsicle sticks) so my clean up is very light. Just throwing in my 10 cents worth,(7.5 cents Canadian) I have also just updated my web site for anyone that's interested, added engine. http://home.cogeco.ca/%7Epietbuilder/index.htm Ken GN1 2992 Canada ________________________________ Message 4 _____________________________________ Time: 07:02:19 AM PST US From: TomTravis@aol.com Subject: Re: Pietenpol-List: T-88 cleanup --> Pietenpol-List message posted by: TomTravis@aol.com I found that "Fast Orange", the hand cleaner in the orange-colored jug works great at removing T-88. ________________________________ Message 5 _____________________________________ Time: 07:38:31 AM PST US From: "Alex Sloan" Subject: Re: Pietenpol-List: T-88 cleanup --> Pietenpol-List message posted by: "Alex Sloan" DJ, I had a serious reaction to the T-88 glue last fall.

Just one comment though. The swing axles have the bungee on the cross struts which allows the axles to swing out as the weight comes on. I don't think the straight axle will let this happen. It would seem to me that the bungee would have to be some where else in the system. I suppose if you made the axle so it would telescope the suspension would work but that sounds complicated. I am sure if I am all wrong someone will tell me in no uncertain terms.

I will do more on another day when I have time to Guess I'm duty-bound to say that you should be above 1000' for stalls, especially power on, if you've never done them in that plane in order to have time for any 'unexpected' happenings. Now having fulfilled that responsibility.... :) Corky's plane, which apparently is rigged well and the wash on the wings is the same, tends to stall straight ahead in both power off and power on stalls.

Speeds will vary as to accuracy of A/S indicator and airplane, so that sort of thing is relevant only in each particular airplane. But my feeling is that you should know your own plane and at what speeds it stalls in all sort of configurations. Remember that with a passenger these things will change somewhat, but with Corky and me both in the plane we saw no ill manners. One last thing: differences in wing wash on each side or differences in rigging of the horizontal stab will effect what happens during stalls, so look carefully at those.

I know how to do them like 'clearing turns, carb heat, etc.) but say in a power on stall. I get a bit spooked by the tremendous angle of attack and view while waiting for this thing to break. I need to practice this before my review is why I'm asking. Do you use full power in a power on stall or cruise ? When it breaks into the stall power on you keep the nose straight with your rudder (to catch a wing that might be dropping) and release back pressure, but do you throttle back some too ? In the accelerated stall I fly it a bit like a slow flight in a shallow left or right turn and then pull the stick back pretty hard til she breaks. Then I rudder it wings level as I add power. Is this correct ? PS-- how much do I owe you for ground instruction ? Thank You !

Combs" Subject: Re: Pietenpol-List: Edwin's comments --> Pietenpol-List message posted by: "Doyle K. Combs" I had a STOL skylane and had some problem with power on stalls. My instructor gave me two options: 1. partial power and 2. accelerated stall, which was nothing more than pulling the plane up rather quickly to make the stall come much quicker. Don't know if this will work in a piet but it might help get ready for the instructor. ----- Original Message ----- From: "Michael D Cuy" Subject: Pietenpol-List: Edwin's comments > --> Pietenpol-List message posted by: Michael D Cuy > > Edwin--- Since my flight review is due this summer I was wondering what are > the proper procedures for a power on stall and an accelerated stall.

Recovery was just as you say... use rudder to keep the nose straight but do not retard throttle... just unload the wing and fly out with power.

That is exactly what I meant. Actually, I just read today that the FAA considers a stall an aerobatic maneuver and requires a completion above 1500'. I agree with the 1500' for safety reasons. I am not sure I am ready to agree that a stall is an aerobatic maneuver. Guess it is similar to modern day definition of a "major" repair...

The gear as in the F&G is well braced as the front view shows. The cross bracing of the gear legs, in tension with cables, is held in compression by the horizontal spreader bars each side of the axle. As you have indicated Jack, a very stout design! The only catch I see is that the inclusion of brakes to the design requires some method of preventing axle rotation. Mike Cuy has a very neat solution to this. The external bracing wires as on the Fly Baby would not work on the BHP design as the axle is held down against the bottom of the V struts by the bungees. The suspension motion requires the V to move down below the axle as the "Jounce" displaces the axle. The bungees return the axle to the rest position "rebound". The Fly Baby has rigid mounting of the axle no suspension.
