Making a Jewelry Reduction Die

Project:
Making a jewelry reduction die for a neighbor

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
I'm saving up for a DRO but because I don't want to take it out of our regular budget, I put an ad on kijiji advertising that I can do some minor machining jobs because I just plain enjoy doing it. I got a call from someone yesterday and after talking for a bit we agreed that I would make him a jewelry reduction die for his press because the one he has doesn't have holes big enough for what he wants to do.

He asked where I lived and it turns out that he's my neighbor from 4 houses down the street. I thought that was pretty awesome. So last night he walked down to my house with the die he already had so I could measure it and make him a second die with bigger holes.

This job actually turned out to be rather time consuming because I had to dial in the 4 holes individually on the 4-jaw chuck (once in the front and then again in the back) and it took quite a bit of fiddling around until I had them all lined up.

After the part was machined, I heated it up to a nice bright cherry red and quenched it in water to make it a lot more wear resistant than if I had it left in its annealed state. A quick sanding with some sand paper and it was ready to go.
