Quick and dirty die-nut.

Good job, I haven’t seen a can of kasenit since I left school. :coffee:

I have a can of Kasenit which I'm very protective of.

I'm jealous of anyone with an old tin of Kasenit.

Following that line of thought i've just ordered some potassium ferrocyanide. Looking at old MSDS sheets for Kasenit it's listed at about 50% sodium ferrocyanide. MSDS sheets for the more modern stuff only list small amounts of potassium nitrate and chromium oxide (but not which kind). I've got a small amount potassium nitrate hidden somewhere so I could try throwing some of that in, but I wonder what makes up the other half of the old Kasenit. Going from the colour of the stuff it could just be powdered charcoal. Sodium ferrocyanide melts at 400°C so I don't think anything extra will be in it to make it famously stick.

It doesn't look like there was much left for threads there, so I'd not trust it to hold up for very long before stripping out again.

Not really necessary, the spindle has virtually zero axial load. The nut just holds a bearing spacer and grease plate in place. The machine operator took the plate off for routine maintenance, damaged the thread, and rather than report it, tried to force the nut back on, hoping it would somehow be ok. Of course it wasn't ok...

Now, I'm sort of having a new workshop, my ersatz case hardening compound is in a plastic container- probably cheaper than the original 'tin' but designed to do exactly the same as the original tin- but the plasticiser would degenerate- and go to powder.
Have a nice day or whatever

I'd like to meet the person who first thought it was a good idea to pack stuff like this in plastic containers. :wack:
Brazing flux is a particular gripe of mine. I get through quite a lot of the stuff at work.
But plastic and hot-bench work just don't mix. One careless moment with the oxy-prop torch and there's another canfull heading for the bin. :palm:

Spilt borax? You should have no trouble with ants.

Of course, you could wash your dirty overalls in it.
