    That's been decades, but didn't you have to group parameters together and write them as a 4 digit hex number?

    I doubt if your 10" cylinder is good for more than 4,000 psi, might be 6,000. But I have never seen 10,000 psi on equipment. You will want to check out the maximum pressure on your cylinder before...

    Also know there is a sliding sleeve on the left end of the lead screw, at least on older machines. When slid to the right, it disengages the lead screw.

    The brass makes me think it is for welding. The construction makes me think of some kind of precision welding, such as tig. The age makes me think its to old for laser.

    They are rear tires, they don't actually do much. So I wouldn't worry to much about changing to a heavier ply rating. An older tire wouldn't bother me, the rubber gets firmer the older it gets.

    How long do you need each section of the profile?...

    How long do you need each section of the profile? Lots of ways to do this if you want 100,000'. Lots of ways for 12" pieces as well, but completely different from the previous.

    I would scribe the radius and mill close to the line with a 3/4 rougher. I would then finish it with a boring head.

    If you are fabricators, I'd rough the radius in with OA torch (or plasma, if...

    I wonder what the hardness would be if the parts were simply retempered.

    As for the high hardness, I expect the self quench is a much more severe quench than using a quenching medium.

    I seem to recall surge brakes are not permitted in some states. Surge brakes don't work worth a darn in the mountains, and don't help when the trailer starts to sway.

    I have used a small mag chuck on both a manual and cnc mill many times. The cnc jobs had fixture plates with pins to stop sliding. Fixture design takes thought to avoid trapping chips.

    Large spindle bores have tradeoffs. Bearings are more expensive. Top speed is usually lower. Price is usually higher.

    It looks like that machine had a recent Chicago job on the saddle. Make sure the ram has some flaking for oil. Lots of sliding contact there. Its not hard to pull the ram from the machine for a...

    I think the items mounted on the wall in the second picture are honing mandrels, probably for a Sunnen. The mechanism on the tailstock intrigues me, looks like a collet closer.

    Yes, I think that's a "small" lathe. My small lathe is a few hundred pounds lighter, the others much heavier. But it is still a very nice size for an only lathe, depending on one's work. I...

    I would rather have a machine setting on a poor floor than anchored to it. And if its a good floor a small machine like your lathe doesn't need fastened to the floor for normal work.

    You don't say whether your plastic mallet is a dead blow type or not. I have dead blow hammers, but they aren't as good as a rawhide or lead hammer for seating parts.
