watched this today and thought a DIY type may like this. It is a simple tubing notcher from another DIY guy on YouTube.

I have been watching his videos, except for the cross cart stuff

Nice video! I had to check out his home page just to find out what a crosskart is. Now I know.

I really like that idea. Let’s say I were to build something similar, then disconnect my x servo and plug in this one in it’s place.
How would I figure out the math for the cut without using G code, but using a drawing program instead?

Like if I have a 2” tube and I want to cut a standard notch for a 90 degree joint in another 2” tube. I get that the cut, if laid out flat, would be kind of a smooth V or sine wave shape. Shouldn’t I be able to just draw that shape with like a 1/2” height and 5” width? Any ideas on how I would go about drawing that shape without just doing trial and error?

For a 90 degree I would draw a circle and break it in half then flip one of the halves around and join them to form like a double hump. Circle would be the diameter of the tube.

Wow, I guess it really could be just that easy. For some reason I thought it would be something more like this, but now that you mention it... it's probably that simple.

I'm going to have to look into that I think...
