The feeds and speeds spreadsheet from IDC woodcraft is a great resorce for saving time on your carves. and plywood sucks for carving.
I think plywood type, bits used, and the desired outcome of the project design plays a big part in whether plywood is an acceptable material or not… I’ve had my wins using it when appropriate
If your plywood problem is tear out you might try a few things.
- sharp bits help. I’ve had some projects where by the time I got to the 10th carve the edges were getting fuzzy.
- you might experiment with climb versus push cutting just to see if you get a better finish.
- there are some bit types like compression bits and down-cut bits that might give you better results with plywood. https://www.cadencemfgdesign.com/shop-1 This is a link to Cadence manufacturing and design. They have a good selection of bits that might help you. Other bit makers have similar products.
Wow, it must be me, or the pine plywood scrap I used.
I used a 1/4 downcut bit, I think it might have been poor quality wood.
