Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance.

  • 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!

    Well I assume you make a 55-deg HSS tool with the proper nose radius similar to a conventional 60-deg thread. - you have the pitch setting on your lathe - I pasted a Gemini response calculating diameters to the custom pitch - link shows Whitworth specific wire diameters to measure PD (unless you...

    I less familiar with Whitworth but is 1/4-22 even a standard thread? I see 1/4-20 (BSW) and 1/4-26 (BSF) and G1/4 BSPP (Whitworth pipe thread) = 19TPI. I mean theoretically you can make any thread form to match some specialty fastener situation if you know the underling formulas, but there seem...

    CA-ON Small Fasteners

    These are good ideas. Am I understanding correct? Red = stock diameter. Yellow = reduced diameter. The SHCS are kind of fine tuning traveling steady's? I guess it would pretty much be a single pass operation but that should be perfectly fine for screws where the head is not appreciably bigger...

    CA-ON Small Fasteners

    Thanks, good to know. It kind of smells like a vendor specific choice unfortunately. Or put it this way, I'm still getting other (RC) hobby hardware from UK supplier no problem, arguably more potential customs hair on it than teeny bolts. Probably not a good time to order anything if its coming...

    Shop Has Anyone Used...?

    We have discussed this quite a bit in the past but the probably strewn about various posts. The answer is it really depends on the shape of part you are holding & what kind of machining forces are occurring. You can readily stick a thin plate down (high surface area relative to low stick out)...

    Benchtop Hobbing Machine - The BHM

    Looks like F360 does not have the equivalent of SW 'lightweight' components? Poop. That functionality provides options to deal with big assemblies in different ways that better utilize memory & faster processing. Or in some cases just processing without failing. At a certain stage of 3D...

    Nice models. I suspect you are probably looking for scale-ish miniature hex head bolts (left) not hex socket head cap screws (right). Unlikely to find hex head in a typical machinery supplier, more than likely a specialty miniature hardware supplier like the aforementioned link. Here is another...

    This is an example of something I've been doing more as of late. When you want to fit something with some degree of snugness but the printer tolerance and/or part tolerance can vary a bit so it becomes a trial & error repetition. Sometimes its easier to make the cavity match the actual part...
