Making your own chamber reamers

[pamrick]

I used my oxy torch to heat treat, bringing the color to cherry red and holding for about 3 minutes. Then I quenched in used motor oil, using a swirling motion to cool the reamer as quickly as possible. I didn't draw the reamer, choosing instead to leave it glass hard.

Some final thoughts on reamer making:
1) Use quality stock for a predictable out come.
2) pay attention to the dimensions and watch the temp on your work. The stock heated up quickly and added a few .001" to the work. I let mine cool a while before final sizing. When it is cool to the touch, I start working again.
3) When reaming, watch chip build-up. Clean swarf often. I didn't expect the reamer to cut so well and consequently, I let chips build up in the chamber. I don't know if this will impact the cartridge performance yet since my dies just arrived and I haven't procured bullets yet.
4) After a reasonably successful result, I will probably make the majority of my reamers from now on.

And yes, in case you're wondering, the cartridge in the picture is what the rifle is chambered for. I'm sure Snailpowered recognizes it. I'll let him tell you more about it since he's home now from the sand box.
