    I don't know, but the dead crap from the last batch of bugs makes good food for the next batch.

    Exactly right: double the time making tools traverse the same path is eminently inefficient. On a tool change frequency optimization basis, multiple parts could/should be fixtured to make the tool do...

    T handles are a lot more comfortable to use if you put about a 3/4" diameter tube for the handle. Helps to minimize hand injury.

    Agree with eKretz: better to harden them in oil than to use as is. Make sure you get them hot enough, it is my impression that, compared to a plain carbon steel, it takes just a tad longer at high...

    I've turned a few rotary shear blades to sharp. I'd typically turn them the conventional way (using the tool tip) until the nicks were machined away. That would leave a burr on one side or the other....

    Strangely enough, my shop made welding positioner carries full welding current through ball bearings with never a problem. I built the thing with old, used bearings from the local motor rewind shop....

    I had this happen years ago with a DC stick welder. My angle grinder was laying on top of the welder and plugged in. Its cord started smoking!. It's the kind of the thing where you can't believe it...

    I'd seriously think about what it means to become some customer company's JIT slave. You can't manage that part time, and if you have guys to crack the whip over, you'll have to do that as well,...

    Exactly! What, the parts get wet in the rain, and then go in the scrap bin because of it? Some customers...do they think a machining center is a sterile environment?

    I test ran a small lathe that would drag the boring bar really bad when withdrawing from a bore. The saddle was cracked at the back of the front V guideway.

    The 'price' of the boring bar has...

    What kind of ways, cast iron, or steel?

    Welding on cast with steel rods will give a very hard deposit and very prone to cracking because of the lack of ductility. The deposit is not really peen...

    I've been using First Data for the last couple of years. The terminal costs something near $1200 IIRC but you can rent it monthly if you wish. I bought my terminal outright, so remaining monthly...

    It is just a matter of the scale resolution. If there are parameters that you can set, then you can 'lie' about what the scale resolution is and perhaps get a diameter equivalent reading out of it....

    Is there some requirement that there be 3 round wires welded onto a tube? How about just milling (or actually hobbing) the feature on the tube as a form of an interrupted spline?

    Might be a 17mm x 1.75 pitch if you are shopping around. Puller screws are often a buttress thread form as well.

    Somebody built it and somebody put it together, so there's no reason it should be a boat anchor.

    I puzzled over the parts diagram I found online, but I can't make out from that where the...

    Is it possible to also cut the wires with your laser welder? What form is the raw wire stock? I'm imagining long pieces of wire. Load the 1/16" tube through the fixture, thread the wires through the...

    Nice work. The micro welding is daunting to me, so without that knowhow, I couldn't price it. I'd be trying to think of something else, like perhaps crushing the tube into a triangular shape or...

    You must be referring to them new-fangled quantum reamers, are you? :D

    But for a newbie, using an adjustable reamer correctly is difficult to do, so I wouldn't recommend it either. You'd need to...

    The taps that I've seen come in a helicoil kit are not ground thread. They cut as good as a hardware store tap, which is saying kind of shitty. A bad thread form could easily damage the helicoil. So...
