that's the temps Wholesale Tools gave me on the phone and the pins turned
out file hard. That's drill rod. I thought it should have been heated red and quenched first but, they said no. Just bake it in the oven so I did and got the results I wanted. They seem to be holding up good so far. No burrs, no bent pins, etc. Isn't that what we care about most? Sucker rod steel tempered right won't need an edge put back on until they're abused against something "too hard". Like trying to cut the face of a rail, that will do it. But, drilling several holes in concrete foundation, or rocks will barely take the edge off those. I've never made much with the drill rod yet. I may learn different once I start making other things beside's dies and this set of pins. So far, that's all I've made from it. Thanks for the comments, you may very well be right. This is the first I've bought and used drill rod. So far, I've made three sets of bushings to neck case's down. From half inch to .191", polished with 1200 they're "polished good enough for this use". Sure, there's extremes with compound, but, this hasn't been needed on what I've made so far. Maybe for a proper die polishing they 'should be' and I'm just at the starting point.

drill rod is a general name for tool and alloy steels there is a-2,w-1, o-1,d-2, low carb. and so on a file test really isn't telling you much if the file is new i can nick mid 50's r,c. heat treat if it's dull you will get about the same reading as 30 r.c. this is why they have rockwell testers and heat treating ovens this is a little more of an exact science.

THAT'S also why us back yard shop guys can't afford Exact Science stuff like that too. Way too pricey. How much of that kinda thing do you have at your home shop?
I'm retired on SS and never felt a need to spend that much on those kind of things. Sure NASA and shops have the bucks to buy such tooling and fine abrasive's and such where a guy tinkering out of pocket don't. I've found over a lifetime of messing with things of all kinds. No matter how good you get, or how fine a polish, or how fine a tools, or shop you have. There's always someone come's along that has more and better. Sounds like this is the case between us. Wish you well, thanks for the input.

george not trying to get into a pissing match with you but you are correct after 37yrs. of tool making i agree there are places that have larger budgets, i have worked for some such as us gov. ordanance and smaller shops. this is more about good tool making practices.bullet dies are precision made this includes dies and punches. yes you can probably turn out punches with emory paper but are do you really think you are holding plug fit tolerances on dia. and squarness of faces with out grinding?also dies need to be in the single digit microinches for internal finish otherwise ejection becomes a BIG problem. as for home equipment between my partner and myself yes we do have a heat treating oven but its more cost effective to send out. heat treating is minimal by lot charge and parts are right where you call out on hardness. if it matters we also have od grinders, surface grinders, lathes, mills,saws, and measuring equip. down to .00001 and yes the 0's are correct. george

No, I'm not claiming perfection. I am claiming and saying: The 1000grit is GOOD ENOUGH for bullets to plink, and shoot pr/dogs with. That's my goal, not perfection. Take care, wish you the best.

George,
We have not thought about using a draw die as we were unaware that a die like that existed. I will run this by my bullet making mate and see what he thinks about investing in one. I imagine Neimie would make one for us if we asked him. Thanks for the new idea. Pete |

Pete:
Believe George U is confusing us a bit with his usage of the proper term: draw die. Actually I believe that's the same thing as a sizer die like Lee makes for sizing cast bullets. works the same, shrinks whatever is pushed thru them to the size it's bored at. Also Pete, I've got some stuff here for steve. IF there's anything over here you'd like to get. Would be a good time to share shipping costs. Also, he's been talking about the many buckets of .22lr's they have around the farm. Be great if you guys could/would join up and get bullet making dies and get into the business. Seems like there's a great need for such in your parts. On: www.castboolits.gunloads.com/swaging. Thor has a .25 cal bullet that looks mighty fine stuffed into a .22lr jacket. No kidding, check it out.

george, theres nothing confusing about this a draw die is used to reduce the dia. in this case we are talking about the for mentioned jackets that are oversized but available to him in australia. these die's have been around for at least 50 yrs that i know being i have an original b&a from the 55-57 era. george
