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...

    Yes, you could do it that way but you would still need to make the offset 60 degree cutter to start as close to the shoulder as possible. The limit, as stated by others, is 1/2 of the pitch of the thread. I do not have any shoulder recess either at the moment for strength considerations as if I...

    Hi All, Preparing to thread the spigot 1/8 NPT. I spent an entire week preparing the various possible toolbits which could be used. The spigot threading arrangement here is rather unique as with the part (spigot) being recessed within the 4 jaw jaws, one needs to use an internal threading...

    A Bit of Canadianna

    Hi All, I know that this forum doesn't deal with history but as a "Canadian" website I don't think many of us here are aware of this bit of Canadian history. I guess I can say that I am one of the first true Canadian citizens being born here in Toronto in 1947. Prior to that year, there was...

    Hi All, Moving on with the actual machining. The very tense part came with the eccentric machining. No matter what tool bit I used, it put a lot of force on the workpiece (as one was constantly turning into a corner) and at one point the workpiece was definitely starting to wobble so...

    A Special Lathe Tool Bit

    Hi All, Here is a special lathe tool bit which I have used many times to get one into and out of a tight spot/corner where no other tool bit will do the job. And if one takes light cuts, it will also leave a beautiful surface finish. This one happens to be ground from a standard brazed carbide...

    Hi All, More test work before I can proceed any further. Part of the problem of finding an alternative way to thread the spigot 1/8-27 NPT and not use a threading die would be if I could single point the thread. This would reduce the gripping and torque pressure on the valve body half...

    Hi Peter, No, you won't drill into the backing jaws as the offset steam through hole intersects with the front recess which you can see in the first photo and in the x-section of the print. Also, the small diameter (which is the rear face of the half body sticking outwards has many more other...

    Hi All, On to the next operation as it gets worse and worse. I am deliberately showing every step by step here to show all of the important details left out in all the other construction articles that are out there. Until you actually have to do it yourself, you really don't know what is...

    Hi All, It just gets trickier and trickier. Proceeding, I decided no further work on the part until I had made up a test piece and I am glad I did because it solved one problem but created another! Why did I need to make up a test piece at all? The problem is the original LBSC construction...
