3D Splitting Cowls made easy

[N2RYD]

Terry,

My father and I are about to split his cowl on his 33% Pawnee. You say to use a thin kerf pull saw how thin of a blade should one use?

I purchased a super thin one, but ended up resorting to a standard hobby style pull-saw. Thin so you don't shorten the height of the cowl and fine teeth so you don't damage the paint works well. You can see my saw in the pic on this post: http://giantscalenews.com/threads/splitting-cowls-made-easy.1827/#post-41876

I believe that is called a Zona Saw

Question. Is there a budget set of equipment for spraying the release agents?

I have a compressor that has a pressure regulator so I just need a way to spray the release agent but I don't want to spend a lot of $$$.

Will probably just use the PAM and electrical tape anyways but wanted to ask.

Yup, if you want to use PVA and don't have spray equipment I recommend a brush. Whenever I'm doing one or two cowls I always use a brush. Just takes a couple of light coats. I think I mentioned that but it's a good idea to note it again so people don't think it is complicated.

Cool, I must have passed over it when quickly re-reading the thread.

I think I'm going to do the cowl on my Slick since pulling it on and off is a PITA. I'll just use the electrical tape and PAM method.

PVA is just but one release agent for fiberglass. If you don't want to mess with spraying you can use paste wax release as well.

True, however the inside of a cowl is not smooth so you would have to gob it in the weave and it would make a mess. Paste wax is a release agent for a prepped smooth plug / mold.

I had plenty of it on hand so that is what I used on my 91" Cowl, I was worried about that but it really was not an issue. I passed a quick 320 over the inside to get rid of any snags but worked wonderful. Parts just fell off after removing the tape.

Super, maybe this would be better than the cooking spray then? I guess if there was excess in the weave the only real mess would be cleaning it out after you are done. Lots of guy's doing fiberglass work use Carnuba paste wax, bet you could get away with that as well.
