Best method for wrapping spars

[balsaaddict]

I have reviewed the thread on best materials for wrapping spars. I have kevlar tow and will use it to wrap the root panel for a Majestic and then switch to kevlar thread to do the mid and tip panels.
I wrapped a couple of bays with the tow tonight using 30 min epoxy on the top and bottom spars only. It is not a very good job and I hate working with epoxy to begin with.

What is a good method to actually do the work? Should I cut a length of kevlar tow and spray it with 77 spray and wrap and then cover the top and bottom with epoxy and then saturate the sides of the shear webs with CA? How tight should the wrap be? I tied the start and then wrapped after coating the first two bays of the top and bottom spars with the epoxy. The tow tends to either bunch up a lot on the spar or more frequently catches on the ribs and gets all out of sorts.

Anyone with a foolproof ( I am the "balsaaddict for good reason) method that will result in a clean and neat wrap? Any help is appreciated.

If you haven't yet installed the LE or TE, the procedure described here in James Osborn's Building Guide (http://www.charlesriverrc.org/articles/allegro-lite-construction/AllegroLite_Center_Building/) for the Allegro-Lite.will work well and should answer your questions.

What towgadget said. Wrap the Kevlar dry, with good tension if possible. Then saturate with laminating epoxy (West, MGS, Pro-Set, etc), and blot while heating lightly. This is neater and lighter than CA. I certainly wouldn't use 30 min epoxy -- the ones I've used are too viscous for this.

A good way to do the actual wrapping is to transfer the kevlar tow to a large dowel or tube. Hold the dowel down on the carpet with your stocking feet, while using both hands to hold and turn the wing. Alternatively, have a helper hold the kevlar spool and maintain tension. This is much better than using only your two hands to hold the kevlar spool and the wing.

Towgadget and Mark,
Thanks for the information. Unfortunately, the LE and TE were already attached. I had to do the wrap by hand. Got better on each panel and think it will hold up. We shall see. I am now looking for a local source for laminating epoxy. I think the local boat repair folks will have West Systems or similar.
