Have a whole bunch of springs mounted on a board spaced appropriately for your cells. You'd probably need a lot of screws to hold the board flat (unless it was an especially thick and rigid material). You would still have to solder/weld a wire/fuse to each spring..but you could do that at high temperatures without risking cell damage. The contact/connection may not be as good as bolt on terminals, but for 18650 cells you could probably get away with it without excessive force. Flashlights do it all the time....(I know, I know...lower current...)
