Re: Mark 1 & Mark 2 details
I went to lathes.co.uk and viewed the 1954 catalog.? The tailstock in the catalog photos looks the same as the one that I have.
The catalog also shows a clamping screw on the carriage, but different than the carriage clamp on the one that I have.

Re: Building an Encloser Box
Happy to hear Mert is doing well. He was such a wealth of great advice.
Best wishes to him.

Re: Building an Encloser Box
I think you are correct. I do believe it was Mert and in the photos I have, it appears to be well done. The vertical milling column appears to provide added support.

Tell Mert that he is missed, he was a great source of knowledge here.

Hi--
Mert's daughter here. Dad's doing fine in his new apartment, but he's no longer online and not doing anything with his unimat.
Dad was living in Barre MA, when he got that base made, and the foundry is still in operation.
Hoping that helps!

Re: Mark 1 & Mark 2 details
Zitat von "John Hutnick" <johnhutnick@...>:
> Attached is a photo of a short bed(12 1/4") iron Unimat.? I have installed a Holland 70w motor with a new line switch and cord.? The details mostly match what I have read for a Mark 1.? However the carriage has straight in horizontal rear locking screw, which is provided for with a boss in the casting.? Lathes.co.uk indicates that the Mark 1 did not have a lock on the carriage.? The clamping method is different than what is shown for a Mark 2.

> Can anyone elaborate and provide more information?
Tailstock looks like Mark 2, on my Mark1 is no locking screw

Re: Building an Encloser Box
Is Mert done with online stuff, or just not back online yet??
Thanks.

Re: Building an Encloser Box
The CAD design I referred to is by Roman and is in the Files under "cast iron base".

Re: Building an Encloser Box
I did just that for my "big lathe" and it has worked well.
Getting the bottom drawer higher than the bed of the lathe helped
a lot.

I may build a 8¡±-12¡±riser on my work table behind my DB-200. On it
I could place my 18¡± wide oak felt lined Gerstner tool chest that
holds all my Unimat accessories. The riser could house the
electrical wires and electronics and have a control panel on the
front (forward, reverse, speed control etc.
I think this could look nice and tidy if well done and easy to
access everything.

Kevin,
Thanks for the pictures. I especially love the one with the lower drawer.

Re: Building an Encloser Box
There was a widely available wooden base with a single drawer, but it's not so easy to find now. These days it is more a matter of finding or making something suitable. I would glue a few bits of wood together, maybe leave the bottom screwed on to give access to the electrics, and a thin panel of plastic or metal on the front for the controls. An alternative I have considered is a simple flat base, with a smaller box on it containing the speed control. I've also considered using the box as a base for a small tool rack, for things like tommy bars and Allen keys, and all those little things that always go missing. I would then put the 24 V power supply somewhere else on the bench, so that mains voltages do not get near the lathe. At the moment I have all the power and speed control in a box at the back of the bench. It is not convenient to reach over the lathe to change the speed, or just to reach the ON/Off switch, but it does avoid having 230 V wiring next to moving parts. I will be looking at placing the speed controller with the lathe on my next 24 V motor conversion - two to do!

An old treadle base would really be cool if you could run the lathe with your feet!
Some years ago at the Guildford club model steam rally there was someone with the whole workbench, centrepiece a DB/SL, all driven off a sewing machine treadle. The only thing that wasn't was the lighting, and I suspect that a small motor used as a generator would be enough for modern LEDs these days. Far longer ago I remember seeing a hobby locksmith using a treadle to drive his Myford. Back in them days electric motors were expensive, and hard for anyone outside industry to buy.

I have several pictures that were sent to me a few years back by a
group member of a riser base with integral enclosure to mount the
Unimat lathe. It was made from a cast iron wood lathe base and was
set up with both horizontal lathe and vertical column. It have
been unable to find a base like that on EBay or anywhere else.
Does anyone on this group remember that setup and the source of a
cast iron base??
Thanks, Dick

The interior spaces can be used to house some electronics, speed controller and hide wires. The front of cast iron base becomes the control panel.
