    Before pressing them out, check whether they are the kind that are split and expand into the hole with a screw.

    I would add that high-quality cermets like Kyocera has produced for 40 years are in a different category of chip formation entirely. It would take quite some fancy camera to show that. Turning 1" Ø...

    I just reread adh2000's post about the dies and I don't know where I got the impression he had to make multiple die pairs. Duh. So probably they were rotary swaging the parts, but they would have had...

    LOL...Yeah, he used to cite Acceptable Techiniques, Aircraft Maintenance and Repair on every other page. Then he'd claim brazing as giving results "equal to, if not superior to, a welded joint." Some...

    What, three or four posts relevant to the subject and the rest nothing but flamewar? Wrong subforum. If you actually own or run a business and your response to the OP is the typed equivalent of SJW...

    The sand contains voids which compress and spoil your bend. To cold-bend it, try a low-melting-point alloy and thread caps into the ends. To bend it hot freehand, don't heat the outside of the bend,...

    OK, I'll try. A 10" long rotary swaging die looks more or less like this. It's nominally 10 inches long; the other dimensions vary with the machine, mostly the height of the hammer dies which...

    The "slipping blade" as a safety measure works on a hand-cranked Bridgeport but not on a powered cut. If you have arbor spacers with key clearance, use a Dremel to grind a keyway in the saw and let...

    I have to wonder about a $70 or $85K "poverty line." I'm not saying it's not effectively true in the areas mentioned, but FFS if it is, why not just leave? Yes, moving a machine shop is logistically...

    Makes one think about roll cages, doesn't it? The late racecar guru Carroll Smith wrote almost 50 years ago in Prepare To Win about "exploding the 4130 myth." Some of his opinions (like "excess...

    No, 4130 is NOT stiffer, that's an old wives' tale. All steel has the same modulus (a hardened steel rod will deflect exactly as much as a soft steel rod of equal diameter). Stiffness in a welded...

    Maybe it has an internal redistribution of mass that relieves chatter...like drilling holes and partially filling with lead shot. Only neater.

    Nope, sorry, all steels weigh the same.

    Un-heat-treated (condition N, sort of process annealed) 4130 in diameters below 2" and wall below .095 isn't significantly stronger than 1020/26 DOM. Its...

    In NASCAR 4130 is not allowed. Mild steel only. In practice they use 1020/26 DOM and have it centerless ground to get down to the minimum (.090) rulebook wall thickness to save weight.
