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!

What does the handle look like? I have a 6" Cylinder square that came with a Kijiji lot I bought. No idea how a handle would work, but open to ideas.

Photos show an adjustable lever handle, I’m assuming so you can set it so that it doesn’t stick over the edge. Having a handle keeps your skin acids off the surfaces of the square and makes it easier to pick/put down straight away from the surface plate.

Fowler shows a U-shaped handle attached in two places on the end of their 22” tall square.

I think I’d rather have the wooden box as it would pick up some of the moisture rather than condensing on the plastic any thoughts? I don’t think this has ever been brought up before. Wood should last longer hinge wise.

Maybe, depends on your shop: I don’t have a rust problem in my semi-conditioned basement, but run a dehumidifier in the Winter (enough A/C in the Summer). I also put Zerust Tabs in boxes that I rarely open. I have some wooden boxes, but mostly steel & plastic.

I would agree about the hinges since the box is one-piece and the plastic hinge will eventually break. However, the hinges on most wooden boxes like those aren’t very robust (but you can replace/upgrade them).

For those that aren't in the know, you can 'prove' any cylinder square. Buying an inexpensive offshore one is just fine. The way they *have to* be made makes them provable.

What I mean by that is you set up your scratch gauge as a squareness comparator, and check it from 4 or 6 angles around the square - by rotating the cylinder square. It is easy to calibrate a cheap one to half-tenths. It doesn't matter if it is off a few tenths, as long as you document it.
