I recently purchased a leigh dovetail jig, which by the way is a great jig, and fairly simple to use. At least once you learn their process. I made my first set of dovetail drawers this weekend and now need to glue and clamp them together. I was trying to figure out how to go about this and figured instead of trying to reinvent the wheel I would go to the well of woodworking wisdom and find out how the wizards or woodworking clamp their dovetail joints together.

Any advice you all have on doing this would be greatly appreciated.

thanks much

I have the same jig, usually the fit is pretty tight and they don’t need clamps. However if I have any loose joints I’ll just use a bar clamp across the face of the box, which only really gets tricky if you’re doing half-blind dovetails.

according to the manufacturer of titebond glue, clamping is required to achieve a proper bond.

I always clamp mine, and yes the jig is a bit complicated and I always have to take out the book to set it up since i don’t use the jig enough but I think it is a great tool

As Garage said ”..just behind the pins with light clamping pressure.”

Use cauls. It ensures the best application of pressure and protects the surface at the same time. Here are some great examples.

I’ve also used just soft pine over the ends of the pins/against the tails and the pressure from the clamp actually creates dents in the pine from the pin ends. This only works well if the joint is close to flush to begin with (which is usually the case with jig&router cut dovetails.
