I was cutting a pattern by Grampa. I was using 3/16" underlayment without a backer. It is not a difficult pattern but the tiger's whiskers are quite fine. some are little more than a couple of blade widths apart. All went well until I was cutting some of those. I will still use the underlayment for many things but I decided to determine how thick is the veneer on that wood.
I saved a small piece that flaked off. Here is what I found The piece consisted of one layer of shelf liner, pattern and veneer. the total thickness of the little sandwich was ..0220. Subtracting the thickness of the shelf paper .0034 and the thickness of the 50# pattern paper .0040, the remaining left for the veneer is .0146.
That is why it is cheap. I don't know how thick the veneer on quality BB is but it is substantially thicker as well as free from imperfections.
Kinda ruined a great pattern. Looks like Woodcraft, here I come.
