  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click 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!

    Cincinnati No 2 Cutter Grinder Restoration

    ball or roller, not urban legend although I suspect of the table is firmly strapped down things would be ok. When I've done it, they come out before transport. The issue as I understand it is that the table is held down by gravity so even small bumps cause it jump and the impact on the rolling...

    lathe chuck (D1-5) and collets, $550,

    I had a look on the weekend, and my :Jacobs Rubber flex had the D1-6 backplate integral, no way I could see that it detaches. I still think they may have come both ways, as I have a smaller Rubberflex i'm going to put on the 10ee that is without a backing plate. You probably need a D1-6 lathe...

    Tool Does Anyone Still Use a Wiggler?

    In that first photo, it looks like you are supporting the rod at the TS end .... shouldn't it float so the end in the centre punch mark is free to move about?

    Good stuff John .... Deepest respect for a project that starts with you own castings!

    Bed Grind-Harrison Lathe

    My first thought is I wouldn't worry about it, what's the win in filling it? .... and there's a downside ..... you're changing the geometry. Whatever you put in there could be tricky to get back in to the same plane as the mating way surfaces.

    3 sided precision straight edge

    a rail that you attach optics to for demonstration, experiment etc. Lets you move things to different focal lengths while maintaining alignment

    3 sided precision straight edge

    The handle suggest the optical bench idea is incorrect. I've always thought "straight edge" that we use to describe the recondition tool is a bit of a misnomer in that they reference flats not edges .... I guess those really are straight edges :) Can't see them being of value to scraping, but...

    3 sided precision straight edge

    I would have guessed that a triangular optical bench rail, how is it advertised?

    lathe chuck (D1-5) and collets, $550,

    I'll have a look at the D1-6. I have smaller Jacobs in need of back plate (going a D1-3) so at least some came with it.... but no sure if some were integral and some not.

    Bed Grind-Harrison Lathe

    Perfect application for scraping. It is very difficult to grind V way geometry to be exactly the same so it mates existing geometry. The usual process to make a lathe, at least back when the fit mattered lol...... was to grind the bed then scrape the components to fit the bed. Also why when...

    lathe chuck (D1-5) and collets, $550,

    , This is opinion not finite element analysis .... don't worry about it. not knowing how long a piece of string is, I mean how big an arbour is :), it's still a beefy mount and the spindle is designed to hand the extremes without issue: biggest lathe, chuck size, biggest work, biggest cuts etc...

    Headstock Bearing Races

    Ah, so all the preload is from the spindle nut. I just did an account of replacing a taper bore roller bearing (taper on the shaft the inner race is drive up on) but that won't apply to yours.

    Headstock Bearing Races

    I haven't had call to do so, but the usual advice is run a tig bead on the inside and as it cools it'll shrink and fall out. When I've had to, there were small holes you can get a brass drift into (protect the bored surface with you life lol). What type of bearings are they?

    lathe chuck (D1-5) and collets, $550,

    I've three D1-6 collet chucks, all 3 pin. Agree with That Guy, comparably, collet work is light work as are the chucks.
