Cutting or sourcing 3mm alu sheet/plate
Hi. I need some aluminium to act as an external flashing.
I need it to be about 3mm thick by 150mm wide and in lengths 3 or 4 meters long. Any of these dimensions can vary a bit, but those are the ideal.
I have rung Capral and a few other suppliers without success 6mm x 150 mm or 3 x 100 are the nearest I can find, which is a bit far from spec.
So I’m thinking of buying a sheet of 3mm and cutting it into strips myself. I have a Ute to get a 3 or 4 meter sheet home no problems.
I would want the edge to be reasonably clean, but most of it will be concealed so doesn’t have to be perfect.
However I don’t want the resultant 150mm strips to be all coiled up or with excessively wavy edges, a result I fear I would get from manual snips. So I guess I’m more concerned with how it lays then how it looks.
What tool would I use for this ?
My first thought was tablesaw, then I thought about kickback, so that’s out (I’m overly scared of kickback after a previous mishap).
Then perhaps some sort of metal shears or nibbler. I’ve never used one however so don’t know what is required - do they leave a neat edge - can they be manual or is 3mm too thick - is there a handheld powered shear I can get from a hire shop which will follow a line?
I am not experienced in working metal so any advice is welcome.
Cheers
Arron
