First spar will be ready for plywood tomorrow. I have worked with alot of epoxy but never t-88. This stuff is great. Long working time and it dosnt run when your turning parts around to apply on multiple surfaces. And cleans up easy enough. Splicing the root filler block was easy and i feel comfortable with it thanks to the input. You guys are more than awesome.

How critical is the 29° angle for the strut brace? $:-\$ Mine came out at about 30~31°. I bought an angle finder for the rest and plan on getting them right on 29°.

Shouldn't be a problem. You can still mount the fittings at 29°

Ok befor i go and make two left wings i want to clarify that if i were standing behind the airplane and this was the right front wing spar the plywood would go on the front correct? And on the back of the rear spar? Also the strut braces and solid root piece will have double 1/8" ply over them in the front where it calls out in the plans? See attached. Also is there a grain direction i need to worry about with the ply?

I am learning lots from your posts/pictures/questions. One of these days it there will be nothing left to do on the airframe and I'll have to start on the wings. Keep posting.

Front wing spars get plywood web on front face and rear spars get plywood web on rear face. I'm not sure I understand your question about doublers but my left wing photo shows how I did mine. I ran the grain direction of the outer ply layers spanwise.
