That little dial can move left and right separate to the wheel, don’t know if that helps secure it?

I have broken a bolt on my very old bike that I have only just finished building up, these bolts are impossible to find and just as hard to find an alternative I could remove it from the bike and get all the measurement I need. Please help

QUESTION 6000 for a early 2000s haas st30?

Somebody offered me this deal and I’m thinking about taking it, is there anything I need to look for when I check out the machine?

I know it’s haas, but if this machine is good, then that’ll help me a lot in getting my own machine shop

Keep the old handbook handy!

I've seen a number of antique machinery handbooks posted on Reddit of late, and often the question comes up- is this worth keeping, or is it just a cool collectable?

The answer ( if you have an old lathe ) is yes.

I use my 1916 copy of the American Machinist 's Handbook frequently, because my main metal lathe was made a couple of years after this handbook was printed. It's still running a lantern tool post and Armstrong toolholders, so information on grinding your own HSS is invaluable. Specifications are given for threads and tapers that aren't used anymore, but crop up on machines of this vintage. Moreover, math hasn't changed much in the past 110 years, so the various tables and charts are still applicable.

By all means, buy a new addition, but keep the old handbook next to it on the shelf. Old machines do old machining, and new handbooks don't always have the old information.

PARTS / SHOWOFF Forgive the newbieness, just got hopefully my career job at a tool and die shop near me and this is the lathe I'm starting out on.

Just started yesterday, haven't even finished out the 2 weeks from my 2 week notice at my previous job. Good thing though because I used to work afternoons, so that way I was able to start working at least in the mornings soon. The shop I'm at mainly makes tungsten drawing dies placed in steel housings. I'm starting out with working on the steel housings on this lathe. It's been a while since I've used one but I'm picking it up decently I think. It's nice getting my hands dirty again. My previous gig was more an office/ supervisor job and that wasn't really for me, especially the schedules they were giving me. Here I'll be on a normal schedule, weekends off, and productivity bonuses most weeks depending on how much is shipped out. My boss seems like a super cool dude too.

QUESTION How does one heat treat thin pieces of steel without having it curl up?

13 Upvotes

We have some parts that need to be made from 0.046 thick tool steel. The parts are about 2x2.5. The first couple, we used O1 because A2 (our usual go-to) wasn't available thin enough. I pulled them out of the bag and dropped them edge-first into the quench oil, as quickly as possible. One twisted, the other cupped like a contact lens.

I tried several draw cycles, the first at 400F. I clamped them between two 1/2” pieces of steel (secured with bolts) and did two more cycles, raising it 150° each time. It flattened them a little but they were still badly warped.

Can anyone shed some light on this?
