This is a neat little guide kit to produce perfect irregular seams or inlays in Solid Surface Materials. You simply make a template of 1/2" material of the seam or inlay you want to produce. Attach the template on the material to be cut. Then, with a special collar installed on the template guide provided, you route around the inside of your pattern throwing the waste away. You then move your template to another piece of material, remove the collar from the template guide, and route inside the template again, this time saving the inside cut. That inside cut drops into the first cut producing a perfect match. Test the repair kit on scrap material before starting the job. The inlay kit is available with a 1/4" diameter - 3/4" depth of cut or a 1/2" diameter - 11/4" depth of cut.
