does anyone know of any clever ways to join sheet metal together with using any mechanical or chemical fixings ie. screw, revits, spot wel ect.
Not too sure if this process exists but I can think of folding the edges of the sheet metal together… pressing I suppose.
check out the links on the thread below …
then register and check out thefabricator,
article on adhesive joining
books (especially OLD ones) are, IMHO, still the best source for sheet metal design details.
‘Notches and Hooks’
