Problem with Dovetail Gadget

Postby piccyman2 » Fri May 13, 2016 9:01 am

Hello
The small problem i have is when cutting the fingers, the drill bit cuts down to the bottom of the finger then moves along the hole than comes up, surely this cannot be correct and it must put too much load on the 3mm endmill.
Looking at the videos it looks like the bit only moves when the above the material, but i cannot be sure.

What ami i doing wrong?

To be honest I don't understand the question. How do you expect it to work if it doesn't move through the material?

The bit moves into the material at full depth rather than the bit coming out of the material and then moving and then plunging into to the material.
I am cutting at 18mm and moving a 3mm bit into the material at full depth isn't very good for the bit.

Have you checked the pass depth on the bit in the tool database? I haven't used the gadget for a while and I'm not at my main machine at the moment but I don't recall it cutting in a single pass when I used it.
