  • 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!

    Tips/Techniques Eccentric turning advice needed

    The longer nose on that design is something I'll incorporate before cutting metal. I was considering making hobbing cutters with this - my lathe is imperial only (no change wheels) so making metric hobs is probably not an option on my machine. I have modelled the Eureka in F360, for metric...

    Tips/Techniques Eccentric turning advice needed

    I am starting to build the Eureka form relieving tool from Model Engineer, Volume 168. This gadget cuts the relief behind the cutting edge of a milling cutter, such as these involute gear cutters. The drawing shows the mandrel which is a triple eccentric turning. I have double-guessed myself...

    iPhone for real-time measurements

    Not very scientific! I just laid the iPhone on the mill table and recorded a spectrum at various speeds. Some runs had a flycutter in the chuck to induce vibrations. There is a better app for visualizing harmonics and modal frequencies though - try (App Store) Vibration Analysis by Dmitriy...

    iPhone for real-time measurements

    I thought some folks here may find this interesting, I came across this app for the iPhone which allows the phone to be used to take physical measurements using the phone's sensors. So far, I have used it for inclination, audio (my dog has a 110dB bark) and vibration monitoring on rotating...

    Tips/Techniques Workshop Organization- things that have made a difference for you

    Keeping the stockroom organised made a huge difference in my shop. Longer stock, up to 40" is kept in these. They are made from baltic birch plywood with heavy duty urethane casters. I have four like this for aluminum, steels, plastics and misc stuff. Shorter pieces and offcuts up to 18" are...

    Blanchard / Surface grinding or just machining

    While the photo is for a different job, the process might work for your project. ("blanchard" grinding a face using a rotary table and a flared cup wheel) If your mill table will allow, after clamping and shimming the work, use a 4" flared cup wheel 320 grit at about 1000 RPM, taking slow...
