You know your stuff. So, I do come upon a lot of drill steels that have had heads flattened and remade into crowbars.
Anything interesting to tell us?

Drill steels from the era of compressed air drilling will be made from cast steel, but given they need to be shock resistant I'd guess on the lower carbon end of the scale. That will make them easier to forge, so to the eyes of a smith they're almost ready-made - just put the curve on the lifting end and taper down the hand end and there you go!

Thanks for that, as I was wondering if the tip had been added for greater resilience. IP: 209.93.13.81

We used to use beef tallow for lubricating screws when making Ash joinery - we used to use ALOT of American White Ash.

Was never tempted to taste it although it didn't smell too bad.....



I remember my father having a Sanatogen tin filled with what was always described as “Russian tallow”, which was used for any screws that might need to be removed at some point. I presume it had been liberated by a relative who worked at the Carriage Works in Derby. Reading your mention of it brings the smell to mind immediately.


If I recall correctly we used the tallow in preference to any other sort of grease as it didn't stain the timber, even over time. Never heard it referred to as Russian though.

Drilling steels had a habit of breaking clean in two if "whipping" was involved, by that I mean using long drilling steels to start drilling a hole with, I had a near miss on more than one occasion as a drillers mate collaring holes for some drillers that insisted using 8 foot steels to start the hole to save on drill steel swopping time.....very bad practice, a jack legged 303 with a drilling steel stub with sharp edges heading full force towards your back isn't good.
