JRB; Yes indeed some of them were Monarchs. I can't recall for sure now which all brands had the flame hardened ways, but am pretty sure there were others beside the Monarchs. Workwd on a large Sidney for a time which was herringbone geard & am thinking it had the flame hardened ways as well. It was about a 24" swing & with those herringbone gears you could hardly here it run. Except for one bad feature was probably the best engine lathe I ever worked on. That feature was that when you lifted the start lever there was virtually no clutch action, it just came on at set speed all at once. I bet that Sidney was quiet. Those herringbone gears were good for side thrust too. I have an advertisement for the Sidney dated 1947.

Looks like this method been invented in Russia about 30 years ago. Also I recall something about "transparent" pieces of flash hardened rolled steel as side effect.

Something similar for cogs where the end result was case colours of 1/32. Is that a typical case colour depth? Hello Raimey, From what I remember reading in Dr. Gaddy's articles, case colour depth was in the microns. JC

In the full article they show a cross section of the plate's hardness. The inside is harder than the outer surfaces. Kind of opposite of case hardening. I'm not sure of the applications in guns but the potential for high stength, thinner, lighter products is huge.

Thanks, Jaycee. I'll have to revisit those articles in DGJ I assume? That dimension is a few magnitudes above stacking elementary particles???
Geno you do know that we are on a 30 year delayed cycle in the rediscovery of the advancements of the Russians don't you??????
Kind Regards,

Hello Raimey, From what I remember reading in Dr. Gaddy's articles, case colour depth was in the microns. JC Raimey, I think you mean case depth, as opposed to case color depth. JC is right in that case color is very thin. Case, on the other hand, can be several thou thick, thicker if you are patient with the soak time. Case is the hard metal "skin," whereas the case color is a thin layer of "oxides and stuff" loosely bound to the surface ("stuff" is related to layer material that makes heat colors of steel). I also understand that the modern samari sword guys have a process that produces case of 0.015" - 0.030". This is offered as the explaination of how a sword can maintain an edge to cut through a phenomonial number of reed bundles in a single heroic blow. Clausing lathes also have flame hardened beds.

Ramey, don't you know most important ideas belong to Russians? And in US as well. Brain drain. Just recall Google for example.
