Floor cutting - isn't alu supposed to be soft?!
Been trying to cut out the floor panel today. I'm going with what I could get for free - which is a 3mm thick sheet of alu - no idea what grade - but it is an old pub sign.
Anyway - i'm getting through jigsaw blades at a tedious rate. I am assuming this is because the alu is so soft it is clogging the blade. The cutting disc on the angle grinder was worse than useless - presumably for the same reason. Am I right - and what can I do to cut the alu more easily / without the constant snapped blades!

You can get Ali specific blades for a jigsaw. They've got extra large teeth!
Might have a hard time on 3mm stuff regardless of blade though, you're best bet, as Davidimurray said, would be some proper discs for the grinder. I've used them for a few pieces and they go through it like butter!

I must whole heartedly agree with Phil on this one, as someone who has just recently left the aircraft industry you are enlightened to the effect that Chromates have on you by breathing them in and believe me when I say it aint good.
WEAR A MASK Arfon
