How to attach 1mm aluminium sheet to 3mm hardwood neatly.
I cant rivet it as its going on wood.. Screwing may be tricky as Id like the ali to be flush.

The sheet will be sat on more than one section of wood,

Any thoughts from the forum massiv ?

Thank you

Please look at the attachment

Is the 3mm hardwood side visible to the end user?
If not, how about a thick angle bracket riveted to the hardwood board, then a countersunk screw bolted through the aluminium plate into the angle bracket.
This will not be massively strong as it is only held on by the top part of the countersink. It will also need accurate countersink holes drilling but it does give a flush solution.
If you don't want to see the screw head then maybe you could glue the bracket to the aluminium sheet.
