Flattening small ali panels
Been busy cutting some smaller ali panels from 0.7mm with my Makita shears and snips and some of the panels have a slight warp and a corner or edge
turned up a little.
What's the best way (or a good way) of getting them dead flat?

as razman says unfortunately pat.
with them shears, when it cuts, it stretches one half when it rattles it, and makes it go wavy. unless you can shrink it, it'll keep popping
back.
you need the fixed blade to run on the piece, and the moving blade to run on the scrap.
.7mm's always gonna wobble all over the place though, no matter what you cut it with.
home made guillotine?

Jigsaw, fine blade and masking tape to stop scratches.

Pat,
I have a hammer that I believe is designed for this job. If it's not, it works very well anyway!
I've no idea what it's called but the entire head piece is a large bar made of what appears to be nylon.
I got it free but it doesn't look like it was very expensive.
Not a lot of help there really I spose!
Cheers,
James

When you cut with shears, the metal on the right hand side should be the off cut. This metal is bent as it curls around the shears. The metal on the
left should be clamped flat with wood and should not distort anyway. TIP....do not snip to the end of the blade with each cut, only use half of the
blade, this stops those small marks from appearing on the edge.
I hope this isn't a grandmother and egg situation !

Depends how small they are but a Stanley knife is excellent for cutting thin ali. Just make sure it's on a flat surface. Run the blade down the
lines a few times using a steel rule or similar and it's dead easy to seperate. Knackers the blade though, oh and be careful with your fingers.

IO can confoirmt that works; you can make a score then bend the metal near the cut so it fatigues and then separates.
