  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Surface grinder wheel hub

    Bought a collection of tools that included a surface grinder wheel hub that fits my SG spindle, but the wheel securing nut has a right hand thread rather than the left hand thread of all my other hubs. I know the R and L hand threading is to keep the nut from loosening when torque is applied to...

    Making a surface grinder wheel arbor

    I have never felt comfortable drilling stones either. Sounds like you missed my earlier comments about adding five minute epoxy to both sides of the stone on the "side" that is light when balancing, then removing some epoxy with a sanding drum on a dremel tool or some other way until the stone...

    Another stray machine followed me home.

    In my experience, the arbor does not have a recess. Your picture is for the wheel mounting hub that does have a recess. I suspect that this makes the hub easier to remove when changing wheels. It is preferred to have a dedicated hub for each wheel, so that once trued and balanced, wheel/hub...

    Drilling using Tool Post

    While this may be helpful, I prefer a lever operated tailstock because it provides a great feel for the drilling process and allows quick swarf clearance when drilling deep holes. I salvaged a tailstock from a Big (to me) Japanese cnc lathe found at a salvage yard, sawed off the original mount...

    Truing a L0 chuck spindle bore

    Excellent idea. I will have to give it a quick try to see how true I can get it to run. Tried to Google "ablative die stones" but Google has no matches.

    I am impressed.

    Truing a L0 chuck spindle bore

    I am being picky of course. I get 0.004 face runout and .002 radial runout......on a four jaw chuck one probably will never find it an issue. Just a solution looking for a problem I guess.

    Truing a L0 chuck spindle bore

    Perhaps you are right. But stoning concave surfaces would be challenging. It occurred to me, as I drifted off last night, that perhaps I could ink up the bore and sweep the surface with a ...say 1/2 in. dia. drill rod and see if any high spots show up.

    Truing a L0 chuck spindle bore

    Just bought a 14" four jaw chuck that just fits my nominally 14" Celtic Mondiale lathe with an L0 spindle. The chuck is used, and it looks like the previous owner didn't bother to clean the spindle and bore many times. The chuck body is a one piece casting. The L0 taper bore has lots of...

    Tool post grinder design

    The way I think about it is that I want the axis of the spindle to be parallel to the work I am grinding whether it be cylindrical or a taper. That at least allows for the most economical dressing of the stone. For a cylinder parallel to the lathe axis, I have a diamond point dresser in a right...
