So I know this has been discussed previously but wondering if anyone has thoughts or ideas on this.
When I go to use Plywood I find that the material is usually not flat and obviously that will cause problems with the focal point.
I purchased some approx 8mm plywood yesterday and found that when I cut the sheet to sections 20"x20" they had a warp in them.
The solution to store them flat with a weight on top is a great one and I’ll look to get some material stored like this for future use but that doesn’t solve the situation when you need it straight away.
I have used spring clamps to hold down the pieces to the frame and the table but I have to sacrifice cutting area for that.
I recall seeing somewhere that someone hand some “hooks” the used to go over the material and either through a honeycomb table or a blade bed to clamp it in place.
Does anyone else do this or have seen this? or any other wonderful suggestions?
Interesting idea. I usually flip the ply (3mm, never worked with thicker yet) so that the bow is facing down then magnet my corners/edges down (galvanised steel cutting table & neodymium magnets). Then the centre doesn’t poke up like in that video @Nigel_Conroy . You could use the same method he does with the little clips on the edges for thicker wood (since magnets may not work so well on your thickness or you may not have magnetic cutting table), just face the bow down if possible.
