Hello fellow Lumber Jocks! Although I have been doing woodworking for a little while, I am just now starting to jump in with both feet. I have just gotten to the point where I am starting to "get comfortable" enough to actually spend money on wood instead of scrounging for scraps and using Home Depot specials.

One thing I have always wanted to do was dovetails. I have seen (what I refer to) as "Double Dove Tails". I have no idea what the correct term is.


Can you guys/girls shed some light on…
1. The correct term
2. How it is done
3. What tools are needed

I'd appreciate any and all comments, suggestions or ridicule of any form or fashion.

I don't understand why anyone would say you need expensive tools for this. People have been doing hand cut dovetails for ages. This is no different. Do your dovetails a little larger into a different material then cut it square again. Then follow through with slightly smaller dovetails in the normal fashion. It can be done with through or half blind dovetails the same way you would cut them if they weren't double. Just have to do it twice.

I've seen these called double dovetails and inlay dovetails.

You can do them with just about any tool that can make dovetails. Essentially you cut one set, fit in the walnut (for example) plane it flat again and then cut the second set.

If cutting by machine with a jig you will need to change dovetail bit diameters with a larger diameter for the first, and a smaller for the second.

Most of the jig out there can do them, Leigh, PorterCable (even the less expensive 42xx series) etc. Just be sure that you use the right diameter dovetail and straight bit when you cut the second one so they fit. Cutting them by hand is also doable but you have to pay close attention to you sawing angles to keep them even.
