Just wanted to say that the quality of all the products LMI has sent me is awesome!
I was shocked at the outstanding quality of the wood sent with my kit. All the wood in my kit is stunning! I can't wait to work on this project. The quality of the services is top notch and the tools I bought from LMI are top grade.
I am glad LMI sets a high standard in quality all around. I look forward to this project and many more knowing that a place like LMI exists with these standards.
I work in a manufacturing environment so I know the work it takes to keep such a high standard. I know LMI couldn't do it without having good people doing the daily grind. Please let your co-workers and shop staff know that I said thanks for the work they do.
I hope LMI continues this tradition of high quality, it can be hard to find a place that values a high standard.
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.
