a friend of mine brought me a few blunt inserts he had, got the idea of making the holder the 'easy' way: I'm pretty sure some more skilled hands could get to nicer results in minutes.
I a nutshell, I milled a large pocket into the back of a chinese carbide tool, drilled and tapped a hole into whatever position looked good and screwed in the most blunt carbide insert of the 'set'.
The pocket was made about 3mm larger then the insert, with the intentions of quickly filling the gap through electrical welding.
Do not want to tell You how much time later, here's the result of my efforts:
Ugly, I agree. Much worse than the out-of-focus picture shows.
But it worked well, to the point I used it to remove the scale from some cast iron I had at hand.
The picture below shows also a couple of the SH screws I turned to a 'better fit' with the insert.
The next two holders, I made more conventionally (to save some time and electric power)
The tool on the left was a perfect fit, till when I misplaced the hole for the screw. :-((
