Angle Plates

Made a new set of angle plates yesterday from 1/2" thick 4140 hardened and ground, I already had a set of plates that were 1/4" thick and another set that was 3/4", but sometimes the 1/4" thick plates aren't wide enough for stability and sometimes the 3/4" thick ones are too wide to fit where I want them.

These new plates are the standard 30°-60°-90° and 45°-45°-90° but I made another plate with an angle that sometimes I could use which is 22.5°, so I made a 3rd plate at 22.5°-22.5°-135° which will come in handy once in a while.

I didn't take any photos of the machining and grinding processes just a couple photos of the comparison of the 3 sets of plates.

As always thanks for looking and happy machining

Doug

Beauties Doug. Quite a collection of metrics on your table there, always things to measure. Thanks for posting your new additions!

I don't recall seeing any of your posts about your heat treating systems (quench, treat, temper, etc). Is it a commercial oven or shop built? Would love to see/hear more if you are up to it.

Thanks PJs
I do my heat treating using an oxegon and accetylene torch with a 3/4" diameter rose bud tip, it gets the temp up pretty dang fast, I just go by the color of the steel, been doing it that way for many years ol pal, it's something you learn in time and through trial and error.

But I am collecting parts and pieces to build a forge, not to make knives or anything just for heat treating, these large bottles of oxegon and accetylene I have are getting real expensive to refill.

Thanks PJs

Like you, I use 4140 in many of my tools because of the high chrome content making them almost totally rust proof. I have some tools I made over 50 years ago and they look almost good as when newly made.

Yea I hear You
4140 and O-1 are probably my most two favorable metals to work with, their are others but those two are my first choice.

rossbotics,

When I was working for a living I used a lot of A-2 because we were always sending tool steel out for hardening. Now in my home shop I am too frugal to spend the money on outside heat treating so that is why I have gone to 4140 PH and O-1. I can easily harden the O-1 with a torch and oil quench. On an emergency basis, when I was still working, we used to heat treat A-2 with a torch and allow it to quench in still air. It also works.
