I am sure my structure is sound and I have reinforced my outboard and inboard wing ribs, so I will go to the full shrink.

The first drive never worked well - the needle would jump and the male square drive end from the tach cable seems to have been loose enough in the female fitting on the drive that it wallowed out the female end quite a bit. The replacement failed on a flight back from Suffolk, Va. yesterday. The female recepticle for the cable was completely rounded out inside, and there is a lot of resistance in the drive gears. I greased both these drives with white lithium grease before I installed them. I've also lubricated the cable with a NAPA speedometer cabe lube which is a light machine oil with graphite in it. Dirty stuff but good cable lube, I'm told. Both of these right angle drives were from Aircraft Spruce. Wicks has a different model drive, a bit more expensive, but if I keep replacing these ACS drives, I'd rather pay once and be done for a while. Anyone have experience like this, and anyone using the Wicks angle tach drive? Any thoughts on lubricating the angle drive itself. I wondered if the grease is getting too firm at low temperatures. It was in the 50s in flight yesterday and it failed when I started it up after a fuel stop. I'd been flying for about 1.7 hours prior to the fuel stop. I'm wondering if I should try the oil and graphite lube in the angle drive. I notice that the Wicks angle drive has a zerk fitting to allow it to be greased. Any ideas what type grease is recommended?

I have the lower cover on one side. In order to attach the cover, I made a small slit in the fabric just long enough to allow the control horn to protrude. I did a preliminary shrink at 250 degrees, trying to not over shrink near the horn. I still got some gaping around the horn plus the fabric still has some looseness in this area. My question is how do I finish this area off to eliminate the gaps? I am using the Stewarts system. In their video they only cover minor fitting protrusions under the fabric, such as lift strut attachments. In the video, they just covered over the fitting and then slit the fabric after the first shrink. Next they cut a patch that was glued over the fitting. After the patch is glued in place, the area of the patch is not shrunk again. Attached is a photo of what I have now. Rick Schreiber Valparaiso In ________________________________ Message 6 _____________________________________ Time: 11:56:29 AM PST US From: Jim Markle Subject: Re: Pietenpol-List: another covering question I had the same issue. (I'm shrinking to 300deg and using the lightweight fabric.) You can see from the attached pic that the gap (below the patch) had opened up after shrinking. Then I made that "patch" and just cut one slit for the patch to fit over the horn. that allowed me to leave a bit of material up onto the side of the horn to help seal it up. (And yes, I cleaned it up a bit so it doesn't still look so messy!) Hope this helps....

Slip it over the horn and glue it in place. It might still gap a little, but should be a pretty good fit.

After my patch was on, I heated it some to make sure the edges laid nice and the patch had a small amount of shrink/tension on it.

My son made the hubs 6 inches wide stainless steel with stainless rotors. The overall diameter of the tires is 27 inches.Things are starting to come together and look like a pietenpol. It's beem about 20 months since we started.

Part of the problem is my control horns are made from flat sheet and so have little thickness when compared to the formed control horns. When I shrunk the cover near the horn it gapped a fair amount. I was afraid to shrink it till the surface was perfectly level.

You can wash all the old lube out with solvent and re pack with moly from any autozone, etc. If you're concerned about extremely lw temps, you can mix the moly grease with some 10 wt oil to make a really light wt grease; just make sure you mix very thoroughly. I've done this on speedo heads and small mechanisms for years and never had one seize as yours has. Just make sure you're wearing old clothes, as moly cannot be removed from anything. -------- Tom Kreiner Read this topic online here: http://forums.matronics.com/viewtopic.php?p=372175#372175 ________________________________ Message 12 ____________________________________ Time: 04:03:08 PM PST US From: airlion Subject: Re: Pietenpol-List: another covering question I am in the process of covering my wings now and I glued a small piece of 1/16 in ply around the horn.
