All my measurements are in inches. So one revolution of my lead screw equals.050” That is because I installed an inch leadscrew. No more manual conversion. Dick -- http://www.homemadetools.net/

One millimeter is 0.03937 inches. For convenience we usually round up to 0.040 when making back-of-the-envelope calculations, but that rounding error will compound over the length of the leadscrew. So

Looks like great fun but dangerous (from a wallet draining point of view)… luckily I’m in the UK so will avoid the risk! :-)

To maybe return this topic to something about machining, Unimat vertical columns were being discussed.? I happened to get an Email with a Harbor Freight coupon for 15% off anything.? If you need a

Hi Gang: Here is the white blank with black inserts: This is the vernier for a 7.5° dial. So 10 spaces equal 1.1°. See it at Cabin Fever next week! Who else will be there? Carl.

If you are making your own, an old hack from the Gingery series is to get a very thin metric measuring tape, like the pocket ones that are about 1/4" wide. Turn a dial to the correct diameter for that

Little Machine Shop is located in Pasadena. And even the parts of the county not on fire currently are probably over-run with refugees. I grew up out that way, and the population has about doubled

Yes, the Unimat is a metric machine, having a leadscrew of 1mm pitch.? The practice of 40 divisions is a carryover, saying that 1 division is .001.? 1 division is actually .03937".? So with a 50

Hello: Why 50 graduations? The lead screw is a 1mm pitch, or 0.040". Wouldn't 40 graduations be more useful? 1/50 would be 0.00078" while 1/40 would be 0.00098". Also I just made a dial from white

I think because they were talking about a supplier called The Little Machine Shop, which apparently is located in Pasadena, California (in the USA).

For my needs I will use a dial with 50 graduations as I use imperial measuring tools. I have been using this system all my life. No point in me changing now at my age. -- http://www.homemadetools.net/

Where is the connection between lathe dials and wildfires? I am super puzzled. Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ Sent: Friday, January 10, 2025 8:12:21

If you don’t want to make your own resettable dials you’re only other option as I see it is to purchase what you need. It may be a challenge finding them right now due to the wild fires in

Sherline has adjustable handwheels for their metric lathes, but they cost about $50 plus shipping and I don't know the the size of the shaft hole.

I was able to spend some time on the Little Machine Shop website earlier today and found a dial and handwheel that are listed as replacement parts for some Micro Mills. The dial shown has 40

The 40 type is generally for us as amateur machinists who think inch to metric to inch concepts. For my brain, with a Unimat, a 50 dial is a lot better.? 10 being .2m , 20-.4, and so on. A pre-made

I thought it might be worth noting that the Little Machine Shop 40 divisions is meant to make a metric unit lathe emulate an English unit lathe. They use 1 mm screws (with the exception of the "true

I searched online and on Ebay, and found no resettable dials/knobs for Unimats.? On Littlemachineshop, I found a graduated dial 40 divisions, which is labelled for 7x10 mini lathe.? Is there one for

My needs are different from yours as I am going to install an imperial lead screw in place of the original Unimat lead screw as it suits my messing needs. Dick -- http://www.homemadetools.net/ forum/
