Oh, BTW... I looked at the MSDS for some of the commercial synthetic and semi-synthetic quenchants and they all seem to contain polyethelene glycol (PEG) as the main ingredient. That's the same main ingredient in most of the flood coolants such as Synkool. I suspect the products are very similar. I'll do a few tests next time I do some heat treating and let you know how it goes. Our weather warmed-up along with some humidity and the desire to do this has dropped-off a few points...
Much thanks for the thoughtful reply and product links.
The stuff I work on is either for my own shop-made equipment (in which 1045 is just fine) or for adaptors of various sizes to convert pulleys, sheaves etc. and a handful fabrication parts for lawn mowers and tractors that do not really even need the surface hardening. This is all a lead-up to the bigger picture/plan I have in mind.
