Lathe Tools from Oil Hardening Steel
Lew_Merrick_PE:
What you Brits call silver steel is called tool steel here in the States. It (here, at least) is available in rounds, square, and rectangular shapes with fair distribution.

If its a form tool I will drill through the rod and work round the hole to form a radius tool, or more holes for something more complex. I use silver steel as it's what I have to hand, not got any gauge plate. I make press tools from silver steel to use in the arbour press, and they are oil hardened.
A little off topic, but the tools are machined and oil hardened (10W-30 motor oil). I take stainless tig wire and heat to red let it cool naturally so its soft. I can roughly bend the shape with my fingers then size the ring in the press tool, that helps work harden the ring a little. It's used in some bespoke parts I make and sell. I do a batch of 25 rings at a time, the tool has made a few hundred parts now. So you're not just limited to lathe tools.

:thumbup: That is great. I believe that will come in handy for me in the not so distance future for making other tools. Thanks for sharing

I'm in Australia and call it Silver Steel, but we are the Brits criminal cousins haha..
Interesting, do you also call it drill rod as well? I actually thought it was. Well that is what I have been describing it in the past :doh:

Here in the States, at least, drill rod is round bar tool steel.

Square may be a little hard, but flat stock is used to make drills. Holtzopffel's five volumes show the tools in use in the 1800's.
