Rob Cosman's Dovetail Square

This invention is very helpful! A consistent, repeatable process makes things go so much smoother! When you put the piece in the same spot every time- it removes that variable from the equation and allows consistent results. And its all the thought that goes into this- the 10degree cut on the top corner so that you can get a reference before you make your cut, to the smooth side and the squared up sides of the square- just thoughtful design! Thanks Rob and team- keep coming up with these improvements!

So simple but so extraordinary. Do you absolutly need it? No, but it is worth the cost. From perfect boards clamped in the vice evey time to helping train that oerfect 10 degree Dovetail cut, i reach for this every time I do dovetails and honesty mst od the time I clamp something in the vice.

Rob’s dovetail process enabled me to cut my very first set of dovetails that went together and made a passable joint it just wasn’t very pretty bc i need more sawing practice. By the 5th one i have no gaps on anything. Love his willingness to teach newbies and i hope to get up to one of his workshops one of these days. Can’t recommend his tools enough, they’re high quality and enable a beginner to make beautiful joinery with minimal practice. First and 5th dovetails pictured for reference. Ps, it’s pretty awesome and unheard of these days to have received a phone call from rob thanking me for my order after i placed it. This gentleman knows how to do business and I’ll definitely be a returning customer bc of it!

I thought this was a bit gimmicky, but after trying it during the Train the Hand Workshop, I changed my mind. I find it simple to use and very helpful for lining up my work piece both vertically and at the correct height for my plane.

Great tool that makes squaring up very easy.
