" What's the best way of cutting the sheet metal "
Depends on how thick but....
How about 'Irwin 10504311 Aviation Snips - Straight Cut'. I have bought a pair from amazon, waiting for delivery, but seems to be able to do it. there a a few different makes/ types on amazon quite reasonble too.
I also have a problem working sheet metal. How to easily cut slots out? I have drawn some plans for my own stove to be slotted together simillarly to the nimblewill (but a bit bigger) and I need to cut slots 1.5mm wide 30mm long. I have thought of 1, drilling either end then hacksawing the middle bit out. 2, drilling lots of holes knocking material inbetween out then filing edges smooth. Both seem alittle longwinded for my liking. I have research various hole punches (most seem to do round holes, but some can do rectangles) but these are far far too expensive for my little projects.
So all of you who have made a flat packable stove, how did you cut your slots out?
Thanks for any help.
