...after a long time, I've made a grinding rig but something went wrong

Hello everybody. It's past a long time since my last post. The last months were, you know, troublesome.
This project, that was kind of an experiment, was prompted by the need to cut at an angle steel parts to make the dovetail ways for a cross slide of a DIY lathe that I'm building.
So I conceived a rig that, exploiting an angle grinder, should allow to make a titled, quite precise cut (that was the theory) on steel bars. But things not always turn out as expected.
This is the video where I show the making of, and what went wrong.
Cheers.

Thanks for the video on your Grinder Video

Hi Claudio
You my get there if you provide a depth of cut adjustment for .1 mm passes, this type of grinding needs rapid passes with small cuts, very time consuming but I dont think that will bother you too much. Dry grinding generates a lot of heat very quickly and the wheel will expand as well as the metal. Angle grinding wheels are too hard for this kind of work. Maybe a belt grinding set up would work but still needing some fine adjustment. Good luck with it and thanks for the enjoyable video top marks for enthusiasm.

Thank you mate. You are right about the depth of cut. I admit I was a little bit lazy and made this rig just as an experiment without paying too much attention to details. However now I feel kind of revenge desire :) I'm thinking to make a new version of the rig, but sticking again on the original idea of cutting rather than grinding down.Attachment 35604
