I’m trying the Proofgrade Thick Maple Plywood for the first time and I’m finding that it seems to be very brittle and easy to break. Is this the nature of the material or do I just happen to have a bad sheet? I’m not a wood worker, but I’ve been reading that grain direction may have something to do with strength regarding the cut direction?
Attached is an image of some robot arms I made for a toy project I’m designing. Size wise, they fit into a 2.75" x 1/75" bounding box. They break in the areas that are the thinnest, at 1/8" -1/4". They break while simply trying to remove the protective tape! So not much pressure at all. The surface designs are symmetrically engraved on both sides, so I’m wondering if thats weakening the material? I’ve been prototyping with the Proofgrade Draftboard and dont have this problem. But I do understand that its a different material.
I’m wondering if I should use the solid Maple instead? Or laminate two pieces of the Medium Maple Plywood together?! Is this the nature of the product or a defect?
