probably a dumb question, but why fillet at all?? fillets are stiff, brittle, blobs of heavy epoxy(for their size).(for this argument anyway!)

if light, very comformable glass is being used anyway (say 3oz real satin), why not use the babina/greenly strip inside-seam approach and small hotglue blob every 6in or so, say 2in bias cut strips of satin and let that set up. or say 1in 'tape' for the first run, 2in 2nd. the glue blobs'll hold it tightish to the inside edge and in place while messing around. 2 simple separate steps- tack the 'tape', epoxy the 'tape'.

pull the wires and lay in a 2nd tape layer that you would do anyway. and then the full glass. so you end up w/ abt the same vol of resin, but always an extra layer of struc glass.

that way you get a little more toughness as well as strength. instead of glass microballoons you get glass tension too. And maybe feel better if decide to dispense with the whole inside glass step for the superlights.

do the fillets add that much extra stiffness to the assembly that this wouldn't work? is this approach worth the hassle?

fillit or glasset?
