    14x40 lathe clutch issue

    That is an adjustable slip clutch. The lathe at Protospace ran into this problem when the carriage was run a little too hard. When I took it apart, I found the springs were all bent and compressed. I stretched them out to a semi-consistent length, then re-installed them. I just installed the set...

    Princess Auto in Calgary Moving

    I understand how offensive it was to be driving along in the winter and seeing the PMS sign. It instantly triggered me and made me sad as I thought about my Parked Motorcycle Syndrome. In fact, I am now sad as I look at the snow falling and am reminded that the cure is still a couple of months away.

    Princess Auto in Calgary Moving

    Ah, but for real PA withdrawal try moving here from Winnipeg in the 80's. I was used to shopping at the original PA mother-ship, where PA surplus was a large warehouse of its own beside the PA store. The PA here only had an isle dedicated to a few surplus items. It was a sad transition. I'm not...

    Jacobs chuck at amazon.ca

    Good deal, but it is now listed at $158.02. I guess ya snooze, ya lose!

    anyone willing to do some figuring?

    So, a starting point on figuring it all out is that when threading in CIII mode with the "a" gear at 48 teeth, you have a 1:1 ratio between the chuck on the lead screw, since it cuts 16tpi threads in that mode. The lead screw will rotate one turn for each rotation of the chuck to do that. From...

    anyone willing to do some figuring?

    What is the pitch of your leadscrew? 8tpi or 10tpi would be common if it is an imperial (vs metric machine). Is there a lever that does "I", "II", and "III"? If so, I think something in the chart is wrong, since there is no reference to "I", and two references to "II" settings that give...

    anyone willing to do some figuring?

    I've built a couple of these spreadsheets. For an House of Tools 12x36 and for a Colchester 14x40 clone. In both cases, I came up with a few threading possibilities that were not documented for the machine, or which were close enough that it did not matter. i.e. an error of 0.001" in 10" will...

    Members Meetup Calgary | Coffee Shop | Saturday, Sept 17th.

    I'd come, but I'm busy this Saturday. Just bad timing in my case.

    older Millermatic 130 auto arc

    Great idea on jumpering with a fuse. In all the electronics work I've done, I've never tried that. I will add it to my mental bag of tricks (if I remember). Light bulbs are also very effective current limiters when you are jumpering stuff. I often use them for safety when playing with 120V...

    older Millermatic 130 auto arc

    There are only a couple of reasons it would be shutting down. The first is easy - the thermostat has requested that it turn off. It won't immediately turn off. It will shut off the gas relatively soon (within a few seconds), the burner air / exhaust fan (usually the same motor with a fan on...
