  • 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!

    KBC 830 Mill Tach Install

    The Shopsmith has continuously variable speeds provided by a sheave assembly that operates similar to a Reeves pulley. At the time, it seemed very important to know how fast the spindle was turning, even though my edition of the Machinery's Handbook doesn't have SFM charts for turning arbutus...

    KBC 830 Mill Tach Install

    very nice Mike - I have a similar setup on my wood lathe, but my mounts are much more ghetto... I sacrificed an old cell phone charger to use instead of a battery, wiring it in parallel with the motor. There's a few seconds lag after the motor comes up to speed and the tach catches up.

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    Jim, earlier you reported that you are limited to 50 amps for the compressor, plasma cutter, lighting, etc. Compressors typically draw much more power during start up than while operating. Will you have sufficient capacity to run your plasma cutter and compressor concurrently? That PA 120V...

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    Also, short and fat air supply lines and high flow air filters water/oil separators are a plasma cutter's good friends.

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    https://www.hypertherm.com/en-US/resources/faqs/what-size-air-compressor-do-i-need-for-my-air-plasma-systems/ If you want long, uninterrupted cuts, or continual short cuts then you'll want to focus on SCFM flow rates and duty cycle rather than reservoir size. If sufficiently sized, the motor...

    UPS Charges

    You can avoid some of the UPS charges by clearing customs yourself. You do this in-person at a CBSA Inland Office (I use the one at the closest international airport). This page provides a relatively current step-by-step of the process -...

    Shop Made BXA tool holders

    I use a salt bath @ about 950F to anneal brass. I try not to waste any of it, but a few drips escape, and when they land on steel they turn it a nice black.

    Using the built in levelling system.

    Exactly! - With only centre-line attachments between bench top and lathe, when making an adjustment between the stand and the floor, there are many other components that will twist or compress before any significant torque is applied to the lathe bed. Makes sense to me - with the short bed and...

    Using the built in levelling system.

    Guys, I really appreciate your advice on alignment and how to reduce impacts of using a wood top under a benchtop lathe. Back to my original question, and I'll try to be more clear. On a benchtop style lathe with only 2 mounting bolts (one near each end), is it better to align the lathe (for...
