Rojo Pedro Posted March 21, 2021 Share Posted March 21, 2021 My lovely wife left me for the weekend and I wanted to make a lining hammer so I started with a piece of 1” 1045. I bought this and some 4140 from the ebays, my first known steel. Moved pretty much like what I expected medium carbon to do, RR clips and such... used my new S7 punch made from a pharmaceutical pill punch I bought from Larry Z. Worked a treat used a couple different coil spring drifts to get to my new jack hammer bit hammer eye drift. Drift is a bit long used my guillotine and a lot of heats! as forged. Spent about 6 hours and did a bunch of other stuff including an S7 chisel and drift. Super happy so far and tomorrow I will grind, heat treat and handle. Cant wait and thanks for looking. I will update with finished hammer Quote Link to comment Share on other sites More sharing options...
Rojo Pedro Posted March 22, 2021 Author Share Posted March 22, 2021 First hammer = FAIL! quenched in water and cracked. Maybe because I only normalized it once. Maybe too hot. Not sure. I used it for a while and it works as intended in fact it works pretty well. i hit it very hard on my mild chunk and it feels and sounds good. Im happy with the hardness just not the cracks all in all I learned a bunch and will make another. This one is a bit too extended but I am happy and had a lot of fun. Thanks for looking Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted March 22, 2021 Share Posted March 22, 2021 Probably the water quench caused it to crack. Quote Link to comment Share on other sites More sharing options...
Rojo Pedro Posted March 22, 2021 Author Share Posted March 22, 2021 Yes but I thought 1045 was water quenched. Will use oil next time Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 22, 2021 Share Posted March 22, 2021 Save the extended head one, a day might come when you need to work deeper into a curved piece and it will be exactly what you need. I had one hammer that was on my rack for over a decade as "useless" until I was setting rivets in the peak of a conical helm and suddenly it was *priceless*! When doing heat treat I usually try warm oil first and then if not getting enough hardness go to a more "brutal" quench like brine. Having had some trouble that way before I finally sprung for some Parks 50. Quote Link to comment Share on other sites More sharing options...
Rojo Pedro Posted March 22, 2021 Author Share Posted March 22, 2021 Thanks Thomas, good advice with trying the oil first Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 22, 2021 Share Posted March 22, 2021 It's easy to go from oil to water than from water---crack!---to oil. Once you know what that alloy and that mass and that shape requires, then WRITE IT DOWN in your shop notebook and go on to 1 stop quenching.

Ted Ewert Posted July 4, 2021 Share Posted July 4, 2021 Rojo, very nice first effort. The most important part was that you had fun making it. My wife was telling me recently that as we get older we forget to play. I told her that my shop was my playground. There is nothing quite like walking into the shop and wondering what would be fun to build today. Quote Link to comment Share on other sites More sharing options...
