I've decided that I want to use the Sika process for installing the tip-up canopy for my RV-7A.
I'm at the point where I need to build the "roll bar". This piece must be trimmed in the center, before assembling, so that it fits the fuselage side-to-side.
I know that the Sika process requires 1/4" Sika to glue the rear fixed portion of the canopy onto the roll bar. My question is, does this imply that I should build the roll bar 1/2" narrower than the fuselage, to make room for the additional 1/4" thickness of the Sika on either side (vs what would normally be the width if I went the screw/rivet route)?
For those that have gone before me with this process, can you comment?
