    You could probably get 100 or 200 $ on eBay for it fairly quickly. When I need one, which is when I am making more than about 10 of the same part on my DSM-50, I improvise from a couple of tall pipe...

    This. I feel very sorry for shops that are captive to one customer or even one industry (oil, automotive).

    Heard a report on the radio yesterday that Boeing was planning to cut about 10% of a 160,000 workforce. Some layoffs, some buyouts, most from the Seattle area plants.

    I will be interested to hear how well the solder does after a few years. My gut reaction is that solder makes a terrible bearing material and a worse way material. I'd also think that chips would...

    The 0.02mm/m vials are definitely sensitive. As practical matter, use a less sensitive level first to get things in the ballpark.

    Level Developments makes some vials even more sensitive, by the...

    I used to work for Sequent Computer Systems, not a household name because they sold $million machines in the 1980's and 1990's to run large corporate databases. Sequent was frequently asked to come...

    I bought one several years ago and still haven't had it all the way apart yet (no need). It came set up for Index B42 collets, but I haven't tried popping out the collet taper sleeve. Presumably...

    I seem to remember stark warnings from 30-40 years ago about how dadoes on a radial arm saw was a fool's game, but I never had a RA saw rigid enough to even consider that task.

    Talk to the folks who make air gaging equipment. They can probably do a custom head for that feature, and putting the head on the end of a 22+" shaft would be no trouble at all.

    It's an adjustable gage, like a snap gage but with a larger range of adjustment. With the tooling balls, I'd guess it was intended to test IDs or possibly shallow tapers. If the latter, the faces...

    The taper on most collets is less than 1" long, and considerably less than 1" change on diameter. I'd say you can use any dial indicator for the radial measurement, and if you have a micrometer dial...

    It would not surprise me if that RRG-3 straightedge were a custom job for a guy or a company whose initials are RRG. That thing has a very narrow bevel, so I think it was not a stock casting. ...

    Seriously? Sweden is noteworthy for how poorly they are doing compared to their neighbors right now.

    ptross, you didn't mention the specific collet series this chuck is for (could be 5C, 2J, 22J, maybe some others). Whichever it is, you can find the nominal collet taper angle. Using that, a...

    "So treated" is the key. I have one Sjogren D1-6 mount where a previous butcher turned away most of the locating taper. There is only about 0.050" of contact between the chuck internal taper and...

    Sorry, was going off "5/32 is too big" and didn't notice that was not a close upper limit. If you want something bigger than 1/16, then 5/64 and 3/32 are both standard Allen sizes, too.

    I don't know about 1.75mm, but 9/64" is definitely a standard Allen wrench size.

    The perforated leaning bars are an 80/20 brand extrusion, part 9701. The yellow painted fingers I welded up from 1/8 x 1 HRS. (Or was it 1/8 x 3/4? Not at the shop to check.) They have four sides...

    I don't have a photo of it all loaded up, but I made a cart for chucks, faceplates and QCTP blocks. Collets, spare inserts and toolholders live in other racks or cabinets.
