Re: Jewelers Loupe Head Band?
I have tried this light and did not find it bright enough.? Instead, I suggest buying 2 Ikea Navlinge lamps in whatever version your prefer, and position one on each side of the the work.

Re: Jewelers Loupe Head Band?
If you use the optivisor then take a look at the Quasar Lighting
System.
It fits
over the front of the lens plate & has a LEDs top &
bottom on each end & the centre.
It gets rid
of shadows very well.
I had to
see a dermatologist some years ago & he was using the
optivisor.
The second time that I went I took mine with the LEDs with me.
He tried it out & told his nurse to contact the Jewelery
Supply company to get them for his own use ;-)
I did find
that the wires sometimes pulled a bit so I put a plug &
socket on - eBay has ones for DC power connectors that have
screw connections if you don't want to solder but they are quite
big & clunky.
It also
allows me to plug into a plug pack if I am working at the one
place for a long time.
Regards,
Brian.

Re: Unimat 3 Mill/Drill Attachment Question
Thanks. At a minimum couldn't see how it could possibly work without pulleys.

Re: Unimat 3 Mill/Drill Attachment Question
I think this is a milling column / mount assembly manufactured (or at least marketed) by jjg-tools in Wales. They have a range of U3 add-ons, ball turners and the like.
Looks like you would still need the U3 milling head from an original assembly, so it appears to be an ¡®upgrade¡¯ for owners of the original equipment.

After recent discussions it would be interesting to know what the play is in the alignment (groove) feature.

Unimat 3 Mill/Drill Attachment Question
I have a discount offer from an eBay seller for a mill/drill attachment I put a watch on just to see what it would go for. It's different from others listed and I don't know if it's different item with the wrong name, or simply missing components the seller may be unaware of. The price just dropped to $200 USD from Pounds with $44 USD shipping. Appreciate the education.

Re: Emco Unimat 3 Keep Plate Material?
Hi Gang:
At a hydro
electric dam they use wedges of Lignum Vitae for the main shaft
bearings. As it slowly wears they just push the wedges farther
in. It was cool, the shaft only turns about 12 RPM and water is
the lubrication.

Yes, Lignum Vitae was used for propeller shaft bearings in
ships, quite remarkable I think.

Policeman¡¯s truncheons and bowling balls (lawn bowls) attract

Vitae. I guess the wood turners like a challenge!

If you find a job shop to do it, regardless as to whether you can manage to find out how they did it, please report back.?
Thanks everyone, interesting stuff. I¡¯d be far more likely to get any work like this done by a proper machine shop I think.
?
Yes, is a wonderful site, a true treasure trove. Great for trying to work out just what that piece of machinery on ebay is!

Re: Emco Unimat 3 Keep Plate Material?
Excellent! ?Good to hear you can get an equivalent over there ¡®across the pond¡¯. It¡¯s even green!
?
I don¡¯t use oil on my U3 (not on the bed anyway), and as the original keep plates were a plastic material, an oil-impregnated nylon seemed like a good idea.
?
The ¡®lifting¡¯, or play, issue in the carriage on the bed is a subtle one but very annoying.
?
I have no desire to file away at the carriage, so using thicker material, lightly rebated then shimmed gives me the option to try out solutions in a non-destructive way.

You can machine a groove of any shape inside a tube using an 1850s method that works quite well.?
Get an oak or ash rod or broom stick that is more than 2x the length of the tube. Machine the wood dowel to a slip fit inside the tube. Mount the part on the cross slide rigidly and the rod into a chuck and center on the headstock. Midway in the rod cross drill 2 holes in line about 2 or 3 inches apart.?
File them square for small HSS square bits. Then run a slightly oversized fine thread bottoming tap from the back about half way thru it.?
Grind two short bits with top rake and side and front clearance angles. Position one bit facing each end and a fine grub screw behind it.?
Set up the part and rod on a lathe. Adjust one cutter sticking out a bit. Run the carriage down the rod to the end peeling a bit of metal out. Then adjust the second bit out a little. Run it back down in the other direction.?
Rinse and repeat until it¡¯s deep enough. Slow but effective. You can make the rod out of steel if desired. If you rotate the rod you can use this setup ?for line boring instead of broaching.?

Although I don¡¯t like his lost foam method here¡¯s one way to get your own shaper.
? ? ? Yes.? Shapers were once pretty common.? The production drawback was the time wasted on the back stroke which, of course, does no cutting.? They are designed (usually a straight mechanical design but a hydraulic scheme came later) so the backstroke is faster than the cut stroke to help at least a little bit. Since this group has a small machine focus, there have even been hobbyist sized shapers, notably by Adept in England (almost made a small lathe popular with hobbyists), that are hand powered.? You can see that here: A planer (for metal, not like a wood planer) is another machine some may not be aware of.? It is a cousin to the shaper, but typically larger, much larger, where the tool bit is stationary, and a long table holding the work piece moves to and fro. Charles E.

Re: Emco Unimat 3 Keep Plate Material?
Nylatron is moly disulfide impregnated nylon. It¡¯s very good engineering plastic, tough and slick.?
Delrin af is delrin impregnated with Teflon if I am not mistaken. UHMW ultra high molecular weight polyethylene is quite tough and very slick.?
McMaster Carr has quite a selection of all these plastics. UHMW is also available as thin stick on strips that can be used backed by metal. It is used on tables saw tools and is cheap.?

What size of "oilon" is used?? Has anyone here used this before, and where do you buy in the US?? The cheapest that I found on Ebay is $105 for 12"x12"x.250.
