Isnt it cool how when the punch gets to the bottom, the job lifts it's self up off the bottom die.
Thats when you know that you only have a wafer thin slug to punch out when you turn the job over. Our starting punch that we use under our press is 90mm dia so I suppose that is what size hole we punch. Can go larger, just would need to make a larger starter punch>

hmmm me thinks u need to come watch me some more the other day jay and i punched a 120 hole straight off only cause that was the smalest punch i could find while he stared at me like a dead fish. hmm you will have to get a pic of the pics of the rings sitting on the saw at the moment and take progress pics i am lookin for the pics you have been takeing latley but i think it is just sooo u can look at my prowess because i cant find any around this website

boo i fill the job cards out correctly and put my hancock on it too

1045 can b quenched in water from 850 with no grate hardeness affects and it shouldent crack are u sure it was 1045 ? and as evfreek said typically speeking u should pull it out and temper straight away DONT let it fully cool out if it is somethink a bit better ie.1060-1090 (oil quench) fully cool out temper while stil warm but it can be fully cooled but i am just saying what the books say but beeing a apprentice we allways let stuff fully quench and tember a couple of days later but i have seen hammers crack because they have been fully quenched and left 4 a day. you just have to kno what u are quenching really and anythink with sharp edges like a punched hole will crack if not tempered imedalty
