Default Woodrat Large Dovetail Bit

Has anyone used this dovetail bit before?

WoodRat USA: WR-H-6-50-28

It looks to have a cutting diameter of 28mm (1.10236 inch) and a cutting length of 50mm (1.9685 inch).

I have one in that size range that was billed as a stair tread bit which I got cheap on ebay. I haven't used it yet. I assume the stair tread description was to put a dovetail socket in the riser and dovetail the ends of the treads. My plan was to use it to dovetail the ends of shelves instead. I haven't gotten around to a project that needed that yet.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Used one like it. It is a dangerous cutter, only in HSS, not carbide.
The neck is as narrow as they get.
If you must use it, pre-plow with the biggest dovetail bit in the Leigh jig armamentarium. And pre-plow that one with a straight bit.
Not good to waste the whole profile with this cutter at depth.

Chuck,
I just bought a Hybrid Pantorouter and thought how easy it would be to make a template for it based on the size of this bit. It could then be used to make tail vises like that in the picture. I can actually envision a number of applications for it.

Rob,
So let me see if I got this right, you are going to use this big bit to cut dovetails with so would you size your wood by the length of the bit? I assume you are going to use a template to route these dovetails. I am just trying to understand how useful this bit would be. Seems to me if you were going to make dovetails that big it might be easier to cut them on a table saw. I don't know I'm just asking

Chuck,
I am going to build a split top roubo like the one on Wood Whisperer. I had to sell my last home build bench last year when I moved from the west coast to the east. I was going to cut the dovetail joints for the end vise on the bandsaw, just like in Mark's video. However, I bought a hybrid pantorouter, saw this bit and thought how awesome it would be to make a template to make the cuts. It is something I am considering, but I have a couple of options.

Chuck,
The pantorouter can accept custom, homebuilt templates (but CNC is much better!). The picture below depicts four of the tool's variably spaced dovetail templates. I can envision making two large templates, based on the router bit (above), and making the end vise cuts pretty easily.

I've seen a version similar to it Rob. If you try it I would do like Pat Warner suggested and plough out the center with a straight bit at the least or you could do that with a table saw too. You could in fact cut out the entire dovetail (as long as it's a through dovetail) on a table saw by tilting the blade as the other Chuck suggested and then just use the DT bit for cleaning it up as the saw blade will leave a slightly off square cut at the bottom.
jj777746 and copythat like this.
