“I really appreciate the extra mile you guys are going to make sure your customers are satisfied. I have a degree in business and I've studied all that stuff about how companies are doing their best to keep their customer satisfied through marketing and incentives, but I can't think of another company (in any field) that makes me as satisfied as you guys do. I'm sure there are some places that sell materials here in Japan, but even with extra cost of shipping and customs fee, I prefer to buy from LMI, because I can trust LMI's service and quality of materials. No marketing and incentives can match the solid good service and I'm a very happy LMI customer.”
This tool is great for marking and cutting the rosette trough, the soundhole, and the soundhole reinforcement material. It is well suited as a marking/cutting tool whenever a radius is called for. The SPCC is milled from aluminum and the radius is adjustable from 1 3/16" to 4" radii, with a fine thread mechanism. A ¼" drill rod is used as the registration pin. The blade is high carbon steel made by Ron Hock and is held in place with an Allen head cap screw. The blade block is locked in place by an Allen bolt. Wrenches for each are included.
Beginning with a compass, mark your rosette or soundhole lines. Set the depth of the knife. Mount the cutter on the 1/4" pin that protrudes from your backing board and soundhole centerpoint and begin cutting. Your soundboard should be thickness sanded before attempting to cut out the soundhole as the blade cutting depth is limited.
NOTE: Make sure that the flat side of the blade faces the ledge that is to be 90 degrees. On the initial pass, rotate the cutter slowly as you move into the grain to avoid tearout. Be sure to keep your blade sharp.
Luthier and instructor Robert O'Brien shows how to set up and sharpen the blade in the LMI circle cutter.
