• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. 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. Face to face interactions are required. Please report suspicions to the forum admins. Stay Safe - anyone can get scammed.
  • 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!

    Benchtop Hobbing Machine - The BHM

    Lots of updates and tuning after the shakedown test! Lesson #1 don't rely on set screws. Lesson #2 Turn on brain before operating machinery. I rebuilt the column and key as mentioned before, which improved the column rotary lock significantly. The head is now rigid with respect to the base...

    Help from the electronic gurus

    Its the LED driver. It provides a constant current to the LED. That specific shape and size is probably proprietary, but there are others. Just match the input (115AC?) and the output (usually 12v, sometimes 24 or 36v) to your light. They are available on Amazoom, but it might be less moolah...

    Anyone using ChatGTP?

    I find these AI systems to be immensely useful. I had been using ChatGPT for research (excellent) and coding (not so great) and for "what-if?" questions. More recently I changed to Gemini Pro after wasting a couple of weeks with the chatGPT coding tool CodePilot. Even the latest versions of...

    I can do it. Do you have the stock and a drawing? Based in Abbotsford.

    Benchtop Hobbing Machine - The BHM

    No it does not, unfortunately. The memory/complexity/Euler-math-fail is very probably the source of the problem in Fusion. Over the years I have found a few strategies to help - for example making certain that every component is completely self contained and fully referenced with a foundation...

    Ingenious! I had not heard of Theodore Olivier so I dug a little deeper... Théodore Olivier (1793-1853) was a prominent figure in the development of descriptive geometry and the theory of gearing. He was a professor at the École Centrale des Arts et Manufactures and also lectured at the...

    Shop Has Anyone Used...?

    I don't recall exactly - I ran out! It was a tough plastic tape with a strong adhesive on 2 sides. Used for carpets maybe. I'm pretty sure it was a 3M product.

    Shop Has Anyone Used...?

    Or make a tooling pallet - this one has M6 holes on a 20mm grid. The hold-downs are small and versatile. If you need to finish the entire top of the part, I have found that thin red 3M tape to work very well or a couple of MiTeeBites (sp?) which push from the side and downwards. When the part...

    Benchtop Hobbing Machine - The BHM

    Lotsa learning this week. Mixed in with a load of Fusion Confusion. The F360 models are quite complex - 9 major subassemblies with around 350 parts and synchronized motion. Every once in a while, at random and for no possible cause and effect that I can find - an assembly will disintigrate. All...

    Shop it seems simple, but I need help........ Hammer organization

    Horizontal Piling Spaces are at a premium in my shop, and I agree, hammers are a pest to store and find when you need one. Make a zip tie noose and hang 'em high.

    And the root cause of the vibration under high load..... These things. I used these couplers on the X and Y axes. They are fine for light duty rotary transmission - but axially, they are springs! Under the light loads when cutting plastic and brass, any axial movement was not noticed, but...

    So..... Brass m0.6 gears are not a problem but cutting a steel (1045) m0.8 gear was a real shakedown test. Literally. This is an m0.8 25 deg steel helical being cut just before I abandoned the job. I had it set to a full depth of cut (1.8mm) with a very tiny feed of 0.25mm/work...
