I've been using 6" dacron tape and left over ceconite 102 cloth from a previous recover project. It won't pull easily if the resin is a little green, but once it's cured, it pulls just the same as the advertised peel ply.... because it is the same. There is no magic release coating on peel ply. If you look up the uncertified dacron fabric for covering and peel ply in the Aircraft Spruce catalog, you will see that they are the same part number with the same price. I've been laying up quite a bit of carbon fiber lately. Once it's started to set, I'll put it out in the sun for a couple of hours to cure. Once it's in the shade and cooled off again, the dacron fabric peels off very nicely. -Jeff Scott N1213W -- "Ron Eason" wrote: Polyester garment coat lining will do the same thing for about 1/2 or less cost of peel ply from Aircraft Spruce and others.

No cutting at 45 deg and no overlaps (high spots) to contend with when fairing. Just lay the roll at the root and run it to the tip. A sacrifical layer of deck cloth over that will take care of most pinholes and give a surface that needs very little filling. TIP: Just after doing the layup, sprinkle a generous amount of micro over the entire surface and gently rub it in to the weave. If your hands start to drag then you have too little micro. Be sure to wear gloves for this part. Allow to cure and sand away the excess micro and into the deck cloth for a good finish.

So let me rephrase that and say that I'm going to move the CG aft some (by moving the backup battery toward the tail, and maybe adding a few pounds of lead to the tail spring mount) and THEN I might adjust the horizontal stab. Right now I never need to trim the plane down, it's always in the up direction, so I need to do something to get the nose up anyway. Moving the CG aft some may do it, but if not, changing the horizontal stab incidence will definitely do it. I have a pretty big range of movement back there, but I don't think I'll need much. Until I do that, my top speed will not be optimal.

Standard practice is to install it under a spark plug, but Steve Bennett points out that your CHT temps will read high if you do this... by as much as 150F. He recommends installing it under a head stud (location is given in the text in the Flyer, but not as clear as it could be). Long and short of it is that if you're running a VW and have your CHT sensor under a spark plug, you may not be getting readings that reflect what you're really interested in. If Bob Hoover is still monitoring this list, maybe he would care to chime in? If Steve is monitoring this list, maybe he would care to elaborate more clearly on the preferred location? The picture in the Flyer identifies a boss that is used for fuel injection temp. probe, but doesn't say this is the recommended spot (and doesn't seem to be a good spot anyway). The idea is to respect the metallurgy of the head castings by not allowing the CHT to exceed recommended temperature... bad and irreversible damage can result if the metal gets too hot. Oh, and somewhat timely and related to Mark Jones and Mark Langford's two different approaches to cooling plenum on the Corvair, the Beetle Flyer also addresses cooling plenum design for the VW on the above-referenced webpage.

Dubi One other aspect of peel ply is that it helps to save over all weight as you pull it off it removes some of the excess epoxy that you would not other wise get just by squeege process. Mike Turner Jackson, Missouri Dubi You are correct on all counts. Other hints are: A-Using peel ply will leave a smoother finish with less sanding later on. B-If you are using urethane foam, wipe down the cured glass with a lightly dampened (with denatured alcohol) cloth to remove the waxy residue that epoxy generates in the curing process. This will make sanding easier and faster. Omit this if you are using styrene foams. Alcohol will attack/melt the foam if not totally protected. Not all foams require slurry. Some urethanes are dense enough to simply apply wet epoxy to, then lay your cloth on and stiple and squeegee off the excess.
