  • 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!

    Quote for Small Screws for Camera Lens Repair

    Take a look at old hard disks - they contain a lot of small torx head screws exactly like this.

    Shop Microwave metal casting - some of the best videos I've seen

    Silicon carbide grit is available from any lapidary supplier. The grit size matters (not too coarse, not too fine) and I have acquired a 5lb bag of 150/220 grit which is perfect. It is known as Stage 2 grit if you're looking. Harder to source in any quantity is the sodium silicate (water...

    Shop Microwave metal casting - some of the best videos I've seen

    It is worth watching his series from the beginning - there are lots of tips and tid-bits in there. But the magic answer is that the silicon carbide crucibles he makes absorb almost all of the microwave energy and convert it to heat, without the energy causing arcing in the metal.

    Boring small holes in drop forged wrenches.

    I had a similar problem, drilling 3/16 through a hardened shaft. None of my bits would take a bite, even a solid carbide end mill, but HiRoc drills made by M.A. Ford did the job perfectly. They require a very rigid setup, so don't try it on a standard drill press.

    Product Anchor Lube...

    No, it's not for oiling anchors.... I came across this stuff at KBC, and I've been using it exclusively over the past two weeks instead of the usual cutting oils. It is a creamy, water based goop that stays put and doesn't fly off the work. I like the fact that when tapping deep holes it...

    Taper

    Regrinding the chuck jaws might correct eccentricity in the work, but not a taper when turning. When aligning the lathe, the first test is to fit a fixed centre in the headstock and another in the tailstock. Shim the tailstock or adjust sideways (there should be a lateral adjustment) and shim...

    Best outdoor paint for steel?

    Is that the Enduro 2K product, the 2-part ?

    Best outdoor paint for steel?

    I recommend Tremclad over a zinc primer on bare metal. My railings were put up about 8 years ago. The only rust stains are at the bolts holding the stanchions into the concrete.

    High speed CNC router spindle question

    Yeah, thats where I'm going too. These integrated spindles with their built-in collets are efficient and obviously useful in typical routing applications where high speed is needed and the materials are relatively very much softer. My application is for a small benchtop surface grinder using a...
