Yeah this is exciting! I’m a big fan of cottage industries and like supporting them.

It was time to glue the cowl on permanently and thought of this “clever” way of using a long bolt to capture the cowl to the firewall. Bottom line is that it didn’t work as good as simply holding the cowl to the fuse with my finger while dripping CA glue into the seam.

Before attaching the cowl I glassed the firewall, tailskid mounting plate and rubbed epoxy into the inside of the cowl. The dark area is just end grain balsa soaked with epoxy, it was replacement wood when I cut out the old tail-skid mount. Itís cross grain for no particular reason.

Was happy to confirm that the nose ring of the cowl aligned with the drive washer on the engine after gluing the cowl on permanently. Also happy that I could slip the motor mount and engine in AND install all 8 screws with just a minimum of cursing.

Soldered small washers to the inner part of the axles, bushed the wheels with brass tubing and used a pair of those little nylon push-on retainers to keep the wheels on.

Decided to glass the nose. Gonna try to do it in 4 pieces of .75 oz. cloth with an extra layer of 3 oz. on the bottom for those inevitable nose-over landings. Laminated a roughly 8Ēx12Ē piece of waxed paper to some light (.75 oz.) cloth and still had a patch of 3-4 oz. cloth left over from glassing the wing. Iím going to cut these 5 patches to size then tack them all to the nose and in place first, then squeegee on the epoxy.

Hereís the heavy piece that went on the bottom.

And hereís the lightweight (.75 oz.) veil that gets tacked on top of the heavier cloth. That large piece of what appears to be waxed paper is a laminate of waxed paper and fiberglass veil. Theyíre attached to each other with spray glue. Amazingly the sharpy magic pen leaves a line on the waxed surface. I oriented the patches so the glass fibers were at 45/45 because I think the pieces are better able to conform to the compound curves at the nose.

Next will be the side pieces.

The laminate is easily cut with a pair of sharp scissors and the best part is that the edges don’t fray. Each piece is tacked down and it stays there until you apply the resin.

Left side patch

Right side patch and top

I love using this method because all the cloth is securely tacked in position and won’t move and you can apply the epoxy whenever you’re ready.

I use the West Systems resin with the 205 hardener. The ratio is 5 to 1 resin to hardener. For this project Iíve been mixing up 3 gram batches (that exactly what was needed to glass the nose) 2.5 grams of resin and .5 grams hardener. It amounts to about a heaping tablespoon and think the can says I get 35 minutes of working time although I donít like to push it.
