Say I have an aluminum tube/pipe that has a 5mm
wall. on the iside wall (the inside of the hull) the pattern attached to this
email is on it. with the raised areas (the black bar) "replacing" the need for
bracing straps. think of the white spaces as being 3mm "deep" so that the
majority of the hull would be 2mm thick, but the waffle pattern behind it would
make it 5mm thick in places providing "bracing" built right into the hull. Thus
saving me time/money and weight... I really need to trim ~5kilos of my latest
bugeye design somewhere. I cut it way too close for BugEye II and it was
slightly negatively bouyant.

Casting question
George,
D'you have a drawing of what you're proposing? I don't
follow...
thanks,
Alec
Does anyone know if I do a waffle pattern on my
Preasure Can's inner hull if that can substitute for welded in place braces?
(Aluminum casting, inner pattern is a wide waffle pattern)
Or should I just stick with a straight pipe and
weld the braces/ribs in it like normal?
Fiigured I'd ask before I tried this,
Considering the lack of space I have it's a production to do anything with
casting. but if it'll work I'tll probably be worth it.
Thanks.
