“You guys are the best. I just received my order and literally every time i describe my specifications on how the fretboards should look you guys deliver 10/10. the two long scale indian rosewood fingerboards looks simply spectacular and the ziricote is glorious. I usually dont take the time to write these but this time I had to. Thanks for years of wonderful service guys. And if you can find the guys who helped pick my recent boards, make sure to personally tell them how happy I am."

Calipers, Dial Thickness


8 1/4 inch throat, SPCSM


12.5 inch throat, SPCM

The SPCSM calipers are for measuring the thickness of tops and backs. This extremely well made caliper is manufactured in the USA with a dial gauge made in Germany. The gauge measures up to 30mm in 0.1mm increments. The body is CNC machined powder coated aluminum. The throat has a 8 1/4" capacity.

The SPCM has a deeper throat than the SPCSM to measure wider tops or measure farther across regular tops. Notice that the thumb lever pulls the dial measuring pin from the top so that there is no interference between the caliper frame and the wood being measured. This die-cast aluminum tool measures in .1 mm increments mm with a maximum opening of 30 mm.
