If dovetails aren’t your thing
TailSpin SQd (squared)
Tailspin has something for you “squares” out there.
The patent pending TailSpin SQd has the same ease and accuracy for 90-degree applications. Use SQd to layout box joints that are far more interesting than your tablesaw jig, or mix and match with other TailSpin tools for stunning half-dovetail variations.
Use physical registration to carry joinery layout all the way around a table leg or story marks to an edge or opposite face.
One side has our patented calibrated collinear design; the other works with the tools you already own. You’ll find it a useful addition to your shop.
