Chemical blacking tools

[David George 1Participant @davidgeorge1]

I have just collected my Knurling tool, Lathe spindle drifts and boring bar holder from CBS engineering who has treated them to chemical blacking. It looks great just like bought items.

I note that CBS Engineering use the hot caustic soda process for blacking mild steel, one of the two consistent methods for blacking.

For anyone interested I feel that knowledge of this company is very useful.

Thanks

Caustic black can be done at home, but it is a bit messy and involves some pretty corrosive chemicals.
