Re: Case / base for newly acquired PC/basic
I did something like this a while back, when I built a bench specifically for making miniature parts for an F1 team. I was aiming to use my SL & U3 lathes, plus the little Proxxon mill. I made a cubby

If you don't have a person or machine available to modify this, let me know - I know a man who can.

Re: What is the Best Unimat ? and WHY !
The best Unimat is the DB200. Why? Because it is ¡°Cast Iron¡± and the one and only Unimat I have at present. I also have all the tooling and accessories to go with it and all kept in an oak tool

Huh? There are 59498 messages. This is a fairly busy group for a niche item. Did I misinterpret the message? Neil Morrison

Re: Case / base for newly acquired PC/basic
This as I understand it, this is a Unimat PC, not a regular Unimat DB/SL.? The PC has bed bars of a larger diameter, and should be more rigid and require less support.? Has anyone here used PC

Anybody remember the Sears Craftsman "Rotary Tool Bench"?? I always thought it was sort of bad idea and likely annoying to use.? But I do wonder if, for a small machine, a scheme where it stayed

Re: Case / base for newly acquired PC/basic
Hello Powster: I've built several lathe bases and the heavier the better. My first base was a whole cabinet, four drawers for parts, 3/4" steel slap with tapped holes and a cover, all made from 3/4"

Re: Case / base for newly acquired PC/basic
Mert Baker used a cast iron griddle for that purpose, on one of his DB or SL units. I'd imagine it should be in the photos section, but haven't seen it in quite some time. I tend to use Mert's feats

:/ Meh i would not use plywood but bolt it to a trolley or perhaps if you really want to lift it add yet more weight and use a steel frame but you don't want to add twist to the frame and then to the

Re: Case / base for newly acquired PC/basic
Use 3/4"/19mm plywood, and it should be quite strong enough. Make it just barely larger than the base area of the machine set up as you wish. Put runners of hardwood or perhaps metal under the base

Case / base for newly acquired PC/basic
Greetings everyone, I'm new to lathes and after a few months of yearning, I finally came across a PC/Basic in great condition. I don't have much work space and thus need a semi mobile setup (I.e.

Re: Unimat 4 cross slide screw
I've had a look at off the shelf screwed parts that might do the job. M8 left handed, yes, but not M8 ¡Á 1. I can't get to it at the moment, but I might be able to do this on my brother's slightly

Re: Unimat 4 cross slide screw
The thread is M8 ¡Á 1 Left Handed. You can get dies for this at reasonable prices from China, so after that you need a way to screw cut the initial thread. Larger lathes should manage this. I think

Re: Unimat 4 cross slide screw
Hi Gang: To avoid threading, use two threaded rods and tap the larger to match the smaller. Lock the small thread in with a cross roll pin. Carl.

You can buy threaded rod in nearly any pitch and diameter you can imagine. For that matter, you can buy taps and dies likewise. Right or Left-handed threads, too. I believe I'd buy the tools to make

Re: Unimat 4 cross slide screw

Hi Beck, around July, 2021 I purchased a set of parts to replace the worn out ones on the original cross slide of my 1985 U3. The idea was to improve the overall precision of the cross slide, however
