• 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.

  • 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. Don’t be shy, sign up and come, or plan your own meetup!

WOW, Speed of Machining

Yes, sorry, 18tpi, 2B tolerance.

But "Walking on Water" status, has to include multi-start metric threads (on an Imperial Leadscrew)!!

It also has to include the time to swap out the change gears (gearboxes are for the weak ;)) but then find out you need to order another change gear because the last time you used the one you need, you crashed the carriage and broke off some teeth, but then after ordering a new gear you remember you have a 3D printer which can make change gears for cheap, so you have to call in to MotionCanada and cancel your order and then you design your change gear and finally 3D print it but you mis-measured the bore and the gear is to loose on the shaft so you have to print it again and but then the teeth immediately shear off so you embarrassingly reorder your change gear and then when it finally shows up you realized you were looking at the wrong line on the threading chart and you had the change gear all along so you finally cut your threads.

How long does the American Pacemaker manual claim it takes to do all that? 38, maybe 39 minutes?

Onward or backward! Don't stop.
And when did those lathes come out? In the 40s?

shucks...the DSG has an imperial LS but lets you cut metric without change gears....and has a spindle device letting you do up to 8 starts threads.

I love my lathe <throbbing heart smilie>
