Re: tailstock end of Unimat alloy bed...

In the wee hours of the night, I had an idea for an extended bed Unimat SL/DB to play with. I know some folks here have cut down an alloy bed to use the headstock end for a milling setup. I'd be interested in the rest of the bed... I want to put a set
of longer rails on the bed, with the tailstock mounted to the right of the original tailstock end, so the ends are constrained. Anyone got one they'd be willing to let go for reasonable money?
Almost have my office and benchtop ready to work on my Unis.

Re: tailstock end of Unimat alloy bed...
He wants $50 for a useable bed. I don't want to chop one up, but know at least one got chopped some time back to make a more compact lathe & mill set up. I was perhaps a bit grouchy about it at the time, because it took me nearly 50 years to acquire one of my own. But a guy who needs a setup like that needs it, so it isn't wasting a good machine.?
And apparently they're still more common than I thought at the time, too. :) I'm a tool user,? not a tool collector. Ok, not exclusively a collector. :)

Re: ALERT eBay’s Latest Attempt to Fleece Buyers and Sellers
I suspect ebay's changes to deposit money into your bank account relates to an underlining issue has been a tax issue from governments for sellers who are not reporting income.
I still enjoy the eBay marketplace, and would rather pay shipping then get into a tricky situation meeting someone in person, whom I don't know on FB Marketplace and having purchase
a few items on Marketplace this past year, my credit card company has not been very happy.
I think of eBay as a figurative box of chocolates, where you never know what you will find.... I have found some treasured items, but I remind myself it is a situation of buyer beware.

I use an armature dressing stone.? ?It is made of abrasive imbedded in a rubberized substrate, I chuck the armature in the drill press or hand drill, and undercut the mica with a hacksaw blade or razor saw.? ?

And I have adequately repaired many auto generators by manually filing the armature "round" and undercutting the mica with a broken piece of fine-tooth hacksaw.? The "poor boy" method...

You could certainly use a Unimat to turn a commutator but might have to raise the head and tail stocks even higher than what is possible with the stock riser blocks.? And you would have to rig up some means to do the mica undercutting.

I see, the thing is in the *standard* part.? 8^)
I now recall having read that 14x1.0 is not a standard thread.
So, if I understand this correctly, to make *any* size x1.0 thread, I just
have to use the gears for the 1.0 pitch.
ie: Z50, Z25, Z25 and Z50.
The chart in the post is not Emco issue but it seems to be a copy of the
(corrected) original which was just as confusing for me.
Would have been easier to just match 'gear arrangements' to 'pitch'.
Like the thread chasers for the #150250 accessory, one for each of
the the available pitches. ?
Thank you very much for clearing this up for me.
Best,
JHM

Re: SHERLINE TO UNIMAT 3 THREADING ATTACHMENT ADAPTER DRAWINGS
Pick a 1.0mm pitch from the chart and turn your material to 14mm then start cutting your thread. The chart is only a guide to standard metric pitches. I have cut a M22 x 1.5 pitch thread with this setup. ?

Yes, I've been there quite a few times.
But have not found anyhting on how to make a non-standard thread (like 14x1) with this accessory.
But I'l have another look.
Thanks for your input.

What is needed to get a properly installed grooving tool on the carriage/slide to move/cut towards the headstock at 1.0mm / revolution on a piece of round stock larger than M10?

Hello,
if Jeff decides not to buy the steady rest, I will.
I am located in Spain.
But Jeff has the first chance of course...

You might say it has potential, but there again, potential (difference) seems to be what’s missing.

Brilliant idea to turn your lathe into a generator! ?Just apply electricity to the commutator and then harvest power from the plug. ?Handy if you don’t have, errm, electricity.

Here's one I bought some years ago on eBay. I cannot find a better picture of it.
