I've been reading posts here about dovetail cutters they they got me thinking. How to work around them if you can.
1. I've thought one way was to make three pieces with the 60 deg angle cut on two of them and then screw them together.
2. Another way was to grind your own tool and using arbor press shave the material away like a shaper.
3, Use a shaper.
4. Then finally how they probably make them in production. Broach them. That tooling would cost way too much for a home machinist.
Then I came up with another way. My KDK tool post doesn't require that the bottom of the dovetail slot be the "correct" depth to work.
In fact it never comes into contact with the tool post. It just holed the holder against the post with the dovetail.
So I came up with the following. I made the first one out of aluminum first to test the idea (I knew it would work). I'll end up using it
to mount my indicator.
First I start out like you normally would with a slot.
Then I'll mount in my 30 Deg tooling
The machine the angle.
Done
It works perfectly. Since the bottom of the dovetail doesn't even come into contact the missing material makes no difference.
It won't work for all projects, but where it does it's very fast and easy to do.
