I am in need of a couple things to be more accurate in my work, both machine setup and measurements on wood pieces.
One is a straight-edge/ruler. I would like to get a combined one, rather than separate pieces. I believe most metal rules are not guaranteed to any straighness spec?
Most of the ones I've seen are either 24" or 48". I think 36" would be perfect - long enough to set jointer tables, but short enough to not be unwieldy when measuring/marking wood parts. However the only 36" straight-edge ruler I've found has machinist fractions (0.01") rather than imperial fractions (1/32", 1/16"). Can anyone point me to a manufacturer making an item like this?
Second, I need a set of squares. One 90-degree and one 45-degree should be sufficient for most of my needs. This includes setting blade angles and checking assembled parts for square. Does anyone know if the inside corners of a 90-degree square is spec'ed, or just the outside? In other words, if I want to check an assembled box for square, is the inside surface of an engineer's square any more accurate than a bisic combination square (which I have)? Again, any suggestions for where to buy a good set are appreciated
