  • 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!

    It Looks So Easy and Straightforward ON Paper But...

    Moving ahead. Here is the setup I came up with for holding and centering the boiler blowdown valve body reversed in your 3 jaw chuck when there is virtually nothing to hold on to and your 3 jaw chuck is well used; the jaws are likely bell mouthed and perhaps even sprung. I am deliberately using...

    What Ever Happened to All of the Great Canadian Machine Tool Builders?

    Hi All, Like Standard Modern (made in Toronto) and Excello (XLO, made in London, Ontario)? They could compete with the best in the world at one time. I always wanted a SM lathe or an XLO Knee mill or automatic surface grinder since I went to a technical high school and saw and used them there...

    Does Anyone Recognize This?

    Hi All, This was thrown in with a number of other items which followed me home many years ago. Do you know what machine this is from or what accessory it may be? It looks to be quite well made and there is a small internal taper in the output end of the drive shaft which some other tool fits...

    Do you have a mill and what kind is it?

    a 1973 Millrite MVN Manual Knee Mill - the largest table model (8" x 36"), R8 spindle, 1 HP variable speed motor, no digital readout or power table, 1400 -1500 lbs all up weight. I have acquired many, many accessories, special tools and fixtures for this machine over the decades. It is my "go...

    A Quick and Dirty Way...

    Hi All, Ok, I shouldn't say this, but a quick and dirty way to show how good your 3 or 4 jaw chuck jaws are. It is also a very good test to perform if you are buying any used lathe chuck. Chuck a free machining piece of 1" diameter steel, aluminum or anything else in the chuck which is stuck...

    It Looks So Easy and Straightforward ON Paper But...

    Hi All, On to the next bit of nonsense. The machining instructions given at this point say (and I am now paraphrasing) now reverse the part in the chuck and proceed to turn it down for the threaded boss parts which will thread into the boiler. Well, in my case, this means first machining down...

    How to Produce A (Deep/Narrow) Precision Slot

    Hi All, Moving on to the finishing operations. One needs to have a new or freshly sharpened side tooth slotting saw not just one having phepheral cutting teeth as an excellent finish is important here. I used a 7/32" width side tooth slotting saw followed by a 1/8" thick side tooth slotting saw...

    How to Produce A (Deep/Narrow) Precision Slot

    Hi All, To continue. First rough out the blank and mill it dead rectangular, square and parallel leaving it 0.015" oversize. This is important for if you get this wrong all subsequent machining operations will be wrong also. Ink and layout the central slot leaving the layout lines 0.010"...

    It Looks So Easy and Straightforward ON Paper But...

    To continue with the build. Producing sharp internal 90 degree corners is not all that difficult IF you know a few tricks. The problem is that at a corner you are cutting on two surfaces simultaneously which suddenly increases the force on the cutting tool tip from two directions. This can and...

    How to Produce A (Deep/Narrow) Precision Slot

    Hi All, Guys (and ladies)(I guess there are a few). I don't know why I am telling you all of my secrets. Nobody taught me this; it was only learned through the school of hard knocks. It is probably one of the most difficult of all machining operations. There are many ways to do it wrong and...
