How thick is 1/4" Acrylic? How wide is a 2x4?
I use a lot of Polycarbonate (Lexan) and some Acrylic (Plexiglas) at work. I have long known that 1/4" is really 0.236 (6mm) thick. The material I ordered from rlplastics.com was advertised as 0.250" thick. Usually when someone specifies a dimension to that precision, you should expect to get it. I really did not care if I got 0.236", but would prefer the 0.250".
Everyone knows U.S. 2x4 lumber is really like 1.5" x 3.5", but if someone were advertising 2.000" x 4.000" lumber, you should wonder what you are getting.
Anyway, what I actually received is 0.205"? Their web site actually has an F.A.Q. saying 1/4" is 0.236 and beware of companies that might supply material as thin as 0.220. So whats with this 0.205" stuff.....awaiting answers.
Now, all my stuff is cut thinner than expected. Most of the parts will be fine, but some have tapped holes in the edge that I am worried about. The two X Axis really should have the added stiffness too.
