sealing coro edges
 

Does anyone have ideas for sealing those ugly edges on coro ? I have thought of colored electric tape but have not tried it . Thanks KEITH

Get yourself some sign vinyl (5 yr vinyl is good). Using maybe half inch strips cover the edges wrapped around top to bottom. It looks lots better this way and keeps the oil out of the flutes. I hate it when it drips while on the wall rack. The vinyl is fuel proof and doesn't weigh as much as electrical tape. Ya can get any color that the sign shop has as left overs if you talk nice to them.

That's a great idea
 

Al,

I was wondering the same thing as I look at the tail section on my JKA P-51B. Love the ease of working with the stuff but hate the look of those edges. Never thought about stuff building up in them. Does sign vinyl stretch a bit as well?

It stretches fine and very easy to do. When you are done applying it it looks just like the edge was painted on. Using another color just makes it look [finished].

Also hit it with a heat gun...it shrinks real nice like monocote and really seals it up:)

Thanks Tattoo I didn't know about the heat shrink properties of it. Put together a deb today for my brother who is getting back into rc after a 20 or so year absence. He is like a little kid with this. LOVES spads.

I use light weight spakle... LePage Poly Instafill to be exact. I lather it on with a putty knife, let it dry, then sand it smooth. It makes for excellent wing tips and tail leading edges, and adds practically no weight.

It also takes paint well, and is amazingly durable. Although this may not be so applicable for open planes which often do not get painted.

For open planes, I sometimes use very thin MacTac - or sign vinyl.

Right on!!!!

Some more ideas for straight coro edges...those plastic notebook binders thingies work great. Also, LOWES sells what they call paneling edging that works super!

People use plastic binder strips from office max on the straight edges.

If you have a router or table saw, trim off 1/8" of the edge, cutting off one side of the coro and the flutes, and leaving the other side only. Fold this over the exposed flutes and glue it with CG. Trim the edge flush, I use a belt sander.

Thanks all for your ideas. Now how about the open wing tips . I might try hand carved foam plugs . Any more ideas ??? KEITH

I just Gorilla glued on a couple of tip plates to my Spazzler. When the glue dried, I trimmed them flush with the airfoil (nice, symetrical one). It trimmed really nicely with a combination of # 11 xacto blade and a dremil wood carving bit.

Icarus,

I've never used Gorilla glue. Is that what you build your SPAD's with? How long does it take to dry and does it hold up well?

Thanks
Don

I just tried some monocote on som scrap edges . The results were not to pleasing . Don't heat rounded edge. I also tried covering the flat sides . Ugly wrenkles in line with the flutes ??? I was able to pull it off but i think it would fly. I cleaned the coro with lacquer thinner . I recently painted some coro with automotive base coat - clear coat urethane . I can not dig it off . Warning this is EXPENSIVE paint . I am in the body shop buisness. Have a Spad day , KEITH

Sears carries Gorilla glue, as does most hardware stores. Its polyurethane glue, and must be used with water - follow the directions. What makes it good for the wing tips is that is foams up and expands, forming natural glue gussets INSIDE the wing tip, so you can feel free to trim the tip plate completely flush on the outside, and there is still plenty of glue on the inside... all from a tiny bead to start with! It's good for lots of SPAD stuff, but it takes several hours to cure.

I've sealed coro edges with clear packing tape. Very nice and very tough.

Is this the same as Elmers "Pro Bond" Polyurathane glue . It expands a lot while curring . I have heard someone talk about mixing with water . I have used it on wood and it takes only a little bead and then expands into a firm joint . I have not tried it on coro. How do you clean your coro prior to glueing?? KEITH

I think the Gorilla, and the Pro-Bond are the same idea. I've flamed and cleaned off the coro with acetone as usual when I have used this glue with excellent results. It really works great on wing spars and other places where you don't mind the expansion and overflow around the edges. :)
