    Default It lives!

    My lathe once more turns! Hooray!

    A quick motorectomy, creating a new control box with safety switch, and adding a tachometer. All good. Almost time to start making some chips!

    That was quick! Congratulations. I wonder what the first project will be....

    Thank you! There is still quite a lot of setup and cleanup to do. I think I'll use that time to contemplate what to actually do. After all, when in doubt, procrastinate...

    I don't know about procrastination, I was going to one day, but never got around to it. (Sorry....)
    Starting out and prioritising the purchase of tooling, and from where, is a challenge. The investment can mount up pretty quickly. Needless to say, it's worth it!

    Want to know how to end up with a small fortune with this hobby?
    Start with a BIG one!!
    All jokes aside, this is a fantastic hobby, the best part about it is, that you can honestly say "I made this" or "I fixed it myself"

    Got that ) Still, though my life I've been involved with both professional yachting and motor racing teams. Gives me an idea of what throw good money after bad can really be about

    That's probably not a good place for any switch (let alone a safety switch) or the tacho display
    Switch should be accessible without needing to reach across the work
    Display is going to get covered in swarf, and coolant/ lube if you run it.

    Safety switch should ideally be in front of the lathe, mine is located so that I can operate it with my thigh - it does tend to get switched off accidentally from time to time but I'd rather that that find I can't reach it.

    I agree with BobL, the exposed belts is another safety issue. Maybe make a cover for the belts and mount the tacho/safety switch control box in that area?

    Funny, but I hadn't really thought that through and you are 100% correct. This is the location of the original switch and its mounting plate and, without thinking about it, I used it. Time to reconsider before I start it up in earnest.

    Thanks, Bob!

    There are covers, just not installed while I mess around with the drive belts. They'll be returned before I start working.

    ...and reinstalled )

    Here is the new power/safety switch and tachometer installed below the gearbox, and under the tray. Easy to operate with hand or knee, yet out of the way of mess and accidental knocking. And I needed to adjust the position of the Hall effect sensor a fraction to clear the back gear lever (who knew that is the way to get the second set of speeds?). Then reinstalled the guards, squared away the cables, install the QCTP, and I'm almost ready to make a mess... ;-)

    As a BTW, I've attached a pic of the control box (not quite the final version but close enough). The fact you can get this stuff so cheaply in such compact modules continues to amaze me. We should enjoy it while we can.

    That's come up very nicely. I have also used those tacho modules with hall effect sensor. Amazingly cheap and easy to install. I assume the perforated steel electrical box is the power supply for the tacho?
    Looking forward to the next photos where the lathe is covered in swarf!
    Cheers, Tony

    Yup. It is a 240v AC to 12v DC 2A converter for about $16 on fleabay. It made all too easy.

    I have a few more cleanup tasks to do before spinning it up in anger, but I'm definitely getting closer!

    ...have to start somewhere, and facing some brass seems appropriate. Hooray!

    So it all works. A basic summary: new 240v motor, safety switch, and tach; AXA QCTP; the quick change gearbox needed a bit of help, mostly cleaning and some new oil; the power feeds all work, including the crossfeed; new primary and secondary drive belts (one of those fancy pull-apart belts, works well); the four jaw chuck is up and going again (elbow grease, kero, and oil); and only the fixed steady to restore. Happy with it so far, the restoration (such as it was) has been fun. Now down to (re-)learning how to do some machining.

    One of the first steps is going to remember how to grind HSS tools properly. The surface finish on this brass facing is rubbish! )

    Always satisfying when something you've had in bits actually works when you put it back together!!

    First thing would be to turn your compound around so the handle is somewhere between the 3 and 5 o'clock positions.
    Will stop you having to crank the cross-slide over so far.
