I have a bunch of sheet goods I needed to cut dados in. I took the necessary time to get router centered on the base plate and attached it direct. I bought a 3/8” downcut spiral bit to cut my 3/4” dados. It works flawlessly as advertised with the adjustability to fine tune the width of the joint. I also used a piece of 1/4” plywood as a spacer that I can line up on the mark and butt against the track to get dead on positioning of track to joint, repeatable every time. Will make a spacer for every bit I will use. Would buy it again in a heartbeat! I feel all their products are value priced and the quality and accuracy is heads and tails above the competition! A well thought out product with features no others have! Lastly, Jacob has always followed up with all my purchases to make sure I’m satisfied with the product! Who else does that!!! Keep up the R&D, look forward to what they come up with next!
