I need to pull some beqarings off a shaft. Not having a bearing puller, I was thinking I'd machine a couple of slotted wedger out of oil-hardening stock rather like the wedges used to remove drill chucks. If I try to harden the finished wedges, I'm concerned about properly getting the toughness of the thicker parts of the wedges without losing the temper on the thinner parts. (If that makes any sense.)
I don't have a treating oven, and will be heating with a torch (propane, propane/oxygen, or OA). The last time I did any heat treating was 40 years ago when I made a chisel in high school.
Can anyone offer some advice?
Thanks, Ed Bailen
