Re: Hardening 4130

Note that most metallurgical information is presented for items with cross sections of 1" the information needs to be adjusted for thinner or thicker crossections. How did the pieces fair that were tempered at 450 degF? 400 degF? 375 degF? Checking at one rather high tempering temperature doesn't te...

Re: Eye protection for hot work?

I knew a fellow who had been a professional smith for over 60 years when I met him. There was a period when his output dropped way down due to cataracts and then surged up again after cataract surgery. There was also a fellow over at swordforum using thermite to do all sorts of interesting steel all...

Wow; I've been tracking women's skirt lengths for about 50 years now; say mid 1960's to now, in mainly a single country, USA and in that time alone they range from ankle length to "micro mini" and at times *both* extremes could be found at the same place; both of them saying things about the educati...

As a blacksmith I would NOT suggest a sand pack if you are working hot.

Re: Forging deep vessels

That is the Dupont linkage as used on a Little Giant power hammer. It is used to store energy so that the top die is actually thrown down with a snap instead of just flopping up and down. Also powerhammers need some degree of freedom to be able to work varrying thickness of metal. If the linkage was...
