I'm in the process of making multiple small boxes for a project with dovetail joints. Hanging on to the pieces during transferring the tails to pins was somewhat slippery so I turned to Robert Ingham's jig for help. Mine is a variation of a theme. Primarily for small stock, its adjustable. If you note the cuts in the angle pieces it also applies pressure to hold the pieces in place once you push the angles toward the stock.
The angle is 1/8" stock and I wish I used 1/4" as it would be easier to push against the stock (skinny stuff hurts my thumb!). The jig can be used tails to pins or pins to tails.
Cheers,
Kent
