    The marks on the edges suggest a progressive die to me, so these were probably made from a continuous strip and not on a turret punch.
    But definitely a 100% press job, blanking, punching, and...
  2. One last thought. Is the blank short enough that...

    One last thought. Is the blank short enough that an outrigger support count be moved into the free end of the blank to help support the cantilevered end of the die? If they are punching on the ends...

    0.190" inch deflection!?! They are lucky this thing hasn't busted off in the middle of a cycle and hurt somebody. I was expecting "flexes horribly" to mean something more like 0.025"!

    OK, other...

    Huh. I thought membrane dryers were specific to water vapor. And it does say "membrane dryer" on it, not "membrane filter".
  5. Yeah, the giant clothespin on the right is...

    Yeah, the giant clothespin on the right is generically a vise, and with padded jaws and operated by a foot pedal, for something quite light duty, like stitching.

    The other thing... My first...

    I haven't used the push pump oilers, but I've got a couple of Abnox lever pump oilers and they are really well made. Even those were hard to find in the US, but I did manage to buy from a...

    Yeah, I'm not sure why you must have the cadmium, but if you're willing to experiment with non-cadmium alternatives, I second the suggestion for BAg-7.

    If you're bonding carbide, the braze alloys...
  8. Hardness is not going to affect deflection,...

    Hardness is not going to affect deflection, unfortunately, and practically all alloys of steel have essentially the same modulus of elasticity (rigidity).

    I'm assuming this is a horn press, so the...

    Yeahbut The telco supplies the electricity from a massive battery bank, not live converted from powerco supply. At least if we are talking POTS landlines. And it's not at all unusual for telcos to...

    That was a decade ago, ConnorMakes. You may have better luck sending an email or private message direct, rather then praying they'll monitor a thread that's been idle for 10 years. Click on the...

    That was my thought, but the two scales (which are not cm and inches, wrong ratio, although maybe the bigger units are cm) made me reconsider.

    Well, either OD = 18mm is a mistake (for pitch diameter = 18mm) or this gear calls for a non-standard, custom gear cutter.

    It is good that you know the pressure angle and tooth form!

    Is this...

    In the link Video_Man gave, the cutter is for 0.75 module. If you follow the link, it actually says "Module Pitch 0.75" in the little table on the catalog page. 0.75 module is much bigger than the...

    What are the intellectual property laws like in Afghanistan? (Thar's where your profile says you're from.)

    Ah, thank you Video_Man, I was not aware of that the metric cutter sets use #8 for the rack, where the DP sets use #1 for the rack.

    What's the pressure angle? 14.5 degrees? 20 degrees? Eyeball gauge suggests it's 20 degrees, but you better know for sure before you start cutting anything.

    Given that the dimensions are...

    I am speculating here, as I've not seen bits like that before. But I wonder if they were used in finishing bells/bores for musical instruments.

    MAAP, that was nine years ago. Rather than expect RDUPA to cruise decade-quiet threads, why don't you send a email or private message direct?

    I wear contacts for distance correction as I'm terribly near-sighted. Now that I'm old enough, my distance accomodation is also shot, so I need reading glasses for near work. Fortunately, I found a...

    I have purchased used machines where the grease literally had turned to wax. And lots and lots of old tooling where oils have mostly turned to varnish. Agree with Colt45: solvents and heat. I...

    It definitely has a shelf life. I don't use a lot of it, so the small roll I buy from ULine expires long before I use it up.

    True brazing works better with HSS than O1, because brazing temperatures (over 800F, BAg-7 at 1150F) will take the temper right out of O1, and if you reheat the O1 tip to requench (1400-1500F),...
