    I have machined a little bit of Titanium on simple manual machines and didn't find it very hard. Like Stainless Steel but more so, the heat seems to transfer differently and it would seem to work...

    I don't post a lot. I can be an "askhole". I make a living with my manual machines and provide others with jobs. Most of my work is probably hobby levels and I wonder how any of us without multiple...

    275550275547275548Done deal! Made the part, lathe is working as it should. Due to dyslexia or something, I ordered 954 bronze. I don't know anything about bronze but was surprised by how tough the...

    Thanks guys! I'm going to try the bearing bronze. I ordered a 1/2" x 2" x 6" chunk of 932 off McMaster.

    You will have to put a prop. 65 warning on them anyhow, may as well go for it. The state is taxing federally illegal product, it's a weird deal. One of us could never get away with such nonsense. ...
  7. Bronze type to use for brake shoe inside a SB lathe

    I'm appealing to the amazing brain trust we have on PM. Mt 15" lathe uses a spring loaded brake in the geared head to prevent the spindle from "rolling" while in neutral. Mine has worn to the point...

    3” cutter. The chips were pretty hot. I used those speeds to reduce the size of a 1” square Usa made tool holder (insertable) that was barely marked by a file. It cut with a nice finish so a...

    Today I cut some 4140 ph with my only insertable face mill, the finest chinesium 5 x TPG on a 2” wide part. I took 0.060” cuts at 120 rpm and just over 2 ipm, nice chip formation but the lack of...

    I make them in small quantities, a hundred or two at a time. We use 5-600 a year. I’m buying the filled Teflon molded and skived to my specifications and then use a small jig which I push the band...

    I’m fascinated by those machines. I won’t pretend to know anything about them. I worked in a shop many years ago which had many running all the time. I loved the sound and smell. My job involved...

    That vise looks as if your granddad may have built it. I’m quite sentimental about such things. I suggest fixing the screw so the handle goes back on as was intended and leave the rest of his work...

    I can provide details. There is a problem or two but I think it is good. Let me know what photo or dimensions I can provide. I was thinking of an other use for it but if I can get something for it...

    My friend with a “real shop” laughs at me when I talk about “layout”. I still do it on my manual machines (the only kind I have) to save myself from often made mistakes. I still use a dial...

    Aluminum to Granite in one big step... yikes, don’t want that one ;-)

    Folks do “live on” through their contributions and that’s still a somewhat unprecedented phenomenon. Loosing internet friends...

    In my opinion the double indicators are not a good setup as they degrade the accuracy compared to a single indicator. The nod is the most tricky part and for me it helps to extend the quill and...
  18. Thank you Stephan!

    If you did this in the EU, I would pretty quickly get into trouble.
    Stephan,
    The only reason I can hope to claim to be a “professional machinist” is because I have been providing my family with a...

    I find it both enlightening and mentally enriching to read the different approaches to the problem. If I dont repair it, I will still have learned things.

    Hi folks,

    While not at all inline with my regular gig, a customer/friend brought in a broken part from a rare old bike. Basically it is a simple shaft that connects the two peddle cranks and is...
