Not sure why nobody mentions the Dovetail Template Master, originally patented and sold by Richard Stottman, now sold by Milescraft.
Bought one on a visit to the US in about 2003, have not found better value for money. It does not do true halfblind (need to glue on a cover board) but does through (fixed or variable spacing), angled through, box joint, even wooden hinges.
I have one of the generic quick clamp half blind jigs like the HF one, works fine after setup and provided the wood does not slip under the quick clamp cams. I am talking about occasional use. However, one is limited to the template or templates supplied.
I recently made some drawers for an instrument cabinet. I looked at the half-blind jig, then thought of drawer lock joints as less hassle. But then I remembered making some Stottman designed jigs from the template master 15 years ago. Work off a router table, bearing guided bits, no fussing with guide bushes, etc. Piece of cake. Banged out the drawers in no time.
Strangely, Milescraft do not mention the S3 and S4 jigs on their manual. I still have the original, can scan it if anyone is interested.
