Okay, I think I'm overthinking this, but always good to check. I'm following Bret's log (
http://www.flightinnovations.com/canopy.html), and it seems as if my frame is following the same pattern. Mine's so far looking to be 3/4" high at the roll bar also, like his, with minimal adjustments needed along the side tube profiles to match the side skin / longeron curves.
First question is whether or not I account for 1/8" for the Sika at the roll bar height, considering the windscreen will also be Sika'd? So instead of the 3/16" height the plans call for, would it not be only 1/16" higher than the roll bar we're aiming for at the front canopy frame? Or not, again since the windscreen is Sika'd? This will determine how much of the bottom front tubes to cut down.
Next, measuring the ideal front frame bow width, we have the fuselage width - 1/2" per plans, then another 1/8" subtracted for the Sika. Got that.
The aft bow width, the plans are confusing. Is it fuselage width - 3/8" side skirt inset, and then another 1/4" subtracted for canopy spread? Or was the 1/4" part of the side skirt 3/8"? And then I get it, another 1/8" subtracted for the Sika fillet.
Finally, same idea, the rear height should be not 1/16-1/8" below the aft top skin, but rather 3/16-1/4" when adding in the 1/8" Sika fillet.
Is this all correct?
