  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click 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.

    vacuum switch/relay help

    You can wire this either way. Just depends on that parts that you have / can find. A low voltage switch with a relay to control the AC line. Or a switch that controls the AC directly.

    Tool Tools to set angle on compound fairly accurately?

    To set the compound to a specific angle, one good method is to measure the length of your compound. Use that length as the hypotenuse and then calculate the length of the opposite side (multiply by the sine of the desired angle). Make a spacer that long and adjust the compound so that one...

    Tool Digital protractor or digital level?

    I chopped off that part of my post. Making a linear measurement is the easiest and most accurate kind available. And 3 decimals at 3 inches versus 3 decimals at 3 feet imply a lot less acuracy

    Tips/Techniques Cutting High Strength Steel Forging

    if you have enough power, then I think you could do high speed and high load, but i think you might break something. there is certainly a time factor when discussing material 'failure'. Microseconds matter. At a certain point you are looking at something like the 'viscosity' of the metal

    Tips/Techniques Cutting High Strength Steel Forging

    re high pressure and low speed. Metals are composed of interlocking sets of crystals. When you 'cut' them, you are tearing some at the edge out of the main body. Work hardened material does not have clean edges between the edges of these crystals - they have been smashed together and are...

    Tool Digital protractor or digital level?

    The key point about using a bar + trig is that you can use the larger size to improve your accuracy. And you can make the bar very long if you want versus the small dimension within the rotating part of a protractor (maybe 1" max?, but a bar could be feet long)

    Tips/Techniques Cutting High Strength Steel Forging

    one think to note about that particular drill is that the two points won't line up and there will be two alternating profiles at the bottom of the hole. That means that neither insert will cut along the whole length of both leading edges. And more importantly, because they are not centered, no...
