At a car boot sale, I found a really heavy duty triangular tool insert
holder. When I got home, I found that it would not fit in the tool
post of my huge Herbert 4C Capstan Lathe. No Problem, - sez I,
because I also have an old Denbigh Milling Machine, so I put in a
suitable tool and tried to reduce the thickness, by slicing a bit off
the top. I got a lot of smoke and sparks but very little cutting. I
wonder how I can resharpen one of my slitting saws?!
The tool holder is pretty obviously hardened. So I rigged up a clamp
affair on a heavy duty emery wheel and started to take small grindings
off the top of it as the tip of tool has to be about 1/4 of an inch
higher to line it up with the centre of the chuck. I have made a
spacer to set it correctly, but about 4 hours of grinding, measuring,
cooling, grinding, measuring, sweating, swearing, etc. I have only
done about half. It's a big toolholder.
There must be a better way.
Does anyone know it? Please.
Thanks George.

Gordon Brown has to a large extent removed my ability to actually
spend any money on anything other than essentials like wine and beer.
I have accumulated a host of useful things, without also acquiring a
mechanical engineering background. I was a Mainframe Computer
Engineer for about 30 years and that skill became useless within about
3 weeks after stopping doing it. The generous salary stopped about the
same time.
Ho hum.

Get a couple of the 1mm thick slitting saw wheels for a 4-1/2" angle
grinder and slice the excess off.
For anyone who hasn't come across these they are bloody brilliant.
So quick and without all the fuss of grinding everything away.
With a bit of care they are also neat.
I chopped a 6" square out of a stainless water tank to remove the
heater element which was spinning.
Repaired the back and welded the same plate back in the hole.

They are great, and less than a quid each! I chopped 6" off a
knackered 1" x MT3 drill to make a face mill for my X2 and it works
well. Very little wear on the disk. Perfect also for chopping out the
end of a piece of HSS if making a grooving tool. Far quicker than
grinding it off.
