Re: Unimats as collectables
caryscotthere
Hello Terry,
The 'MK' designation is one I thought up some years ago. I had discovered that there were several variations on the theme for cast iron Unimats. If you watch ebay for an extended period of time you will probably see all of the types for sale. For a full description of each type (MKs 1a thru 4) go to: Then to ENCO, then to DB200. You will find a long read and a lot of photos of these interesting Unimats. The first, MK1a, was only 12 1/4" long at the base of the bed and the way bars were mounted in bored holes and retained by one set/grub screw per bar. They were painted in black crickle paint and the motors were only 40Watts. I have one of these and so does the owner of 'lathes.co.uk', Tony Griffith. Both are complete with original paper. I think his is a little better than mine. There is a early MK4 now offered on ebay. It is not quite pristene but is quite nice and has lots of original accessories in the same silver- blue hammer tone paint. This one will not go cheap if anybody is paying attention. It has the big Dutch made motor of 95Watts. Do go and check out lathes.co. It will give you a better understanding of the differenses in the early cast iron Unimats. The same site also has information on the die cast SLs and the Unimat 3/4. Also a rather extensive collection of information on a broad list of machine tools from all over the world. Best, Cary Stewart |

Re: T rest and gravers?
In the files somewhere there is a copy of American Edestal's price list
circa mid 60s complete with B & W pics of most of the accessories. If you are in a hurry to try your hand at turning on the Uni someone once said that they just chucked up a 6" peice of 3/8" round stock in the milling vice attached to the crossfeed and maneuvered the entire jig to work as a very servicable Tee rest. Smaller sized wood turning tools can be purchased from Micromark as well as Woodcraft Supply amongst others. Good luck. Tom Angell |

I never heard of a MK1a type. Here I though the DB200 was the first model. Thanks for the interesting info.

Hello Terry, Probably the most valuable/rare Unimats are the MK1a type. I have only heard of a total of 5 being offered on ebay in the last 4 years. However, unless you want a relic they are probably the least useful of all the Unimats and they are smaller than those that came later. Now, there was a cast iron Mk4 DB200 in silver blue hammer tone paint with a U90 motor that just sold for under US$200.00. The paint was chipped and there was some rust but it was all there for someone to clean up and use. It was just a good user and not collectable. So sometimes cast iron bargains do show up. Of the DB200s the MK3s are the least seen and the MK4s are the most seen. Either of these types would make good user Unimats and will accept vertually all of the DB/SL accessories. Collectors are looking for the little used pristene examples and are willing to pay big bucks for them. The cost of Unimat 3s has seemed to be stable now at about 1 1/2 time their last new price. I have seen quite a few of them up for sale on ebay in the last few months.

Re: Threading pattern
Thanks everyone for the info and ideas on the threading pattern. I think I will give a try at both solutions, turning a Unimat style pattern and making up a Mert type guide. Can't have too many attachments for a lathe.
While doodling up the adapter and plugs for Mert's threading guide I had the thought that it might be possible to make up a set of guides all with the same OD that screw onto the spindle end. Makes cutting the followers a bit more of a challenge, but thats why I do this. Art, thanks for the references. Just the discussion I was looking for. Jan |

I have made very successful thread masters identical in appearance to the originals on my DB200 Unimat. Outboard thread masters are fine but if you want to get together a stock of master threads for those occasions when you say to yourself, "I just wish that I had such and such thread", then slowly making a full set may be the way to go. I now have a full set of metric and imperial masters, almost half of which I have made myself. I made them last year and message 9712 gives you a quick summary of how I went about it. If you are interested, get in touch with me offline and I will give you more details. Mike -----Original Message-----

Subject: [UNIMAT] Re: Threading pattern Hi Jan There are a couple of pics of the thread former and follower in the "Photos" section in an album "Unimat SL/DB Thread Formers", with a reference to msg #11593 for the dimensions. There is also a pic of a "Custom Threading Arbor" in an album of that name there as well. See info in msg # 11738. Also if you check from msg #11720 forward (and perhaps a few earlier) you will find some discussion on this subject as well. Hopefully this will give you some insight into other methods to consider. Im not sure of the need to hand crank when threading, as it takes repeated passes to cut a thread and unlike a normal threading setup, you just lift the thread follower and slide it back for the next pass while the spindle is running. A slow speed attachment would make things easier. Mert's design is proven to work, but adapting it to the factory attachment runs into using a longer shaft and a smaller spindle pully. I also seem to recall a member describing how he made his guides, but a quick look for it failed. Just some ideas to consider. Hope this is of some help Regards Art --- In UNIMAT@..., "jwitnberg" <jwitnberg@...> wrote: > > When I got my SL1000 it came with a threading attachment.

saw one on e-bay once and he was asking a flat $695.00 for it. I don't remember if he got his price or not. They seem harder to find. There also seems to be ones made for different markets such as the UK (seen on e-bay). Maybe only different labeling though, I don't know if they are cast iron. |

Re: Hemingway Vertical Alignment Device for Unimat 3
Geoffrey,
It would make me very happy if you would sell me the watchmakers spindle part #102200. I would also consider the collet attachment part # 102?00 or I would take it all if the price is agreeable. I appreciate you consideration. Thank you. AL THOMPSON athompson4@... _____ From: UNIMAT@... [mailto:UNIMAT@...] On Behalf Of Geoffrey J.

It is available in the UK and I believe they do a worldwide subscription service. It is a fortnightly magazine so at least 26 copies a year I think. There is also Model Engineers Workshop by the same people which is more concerned with tools than steam engines. This is only 10 issues a year. Have a look at www.magicalia.com If you are still stuck get back to me. regards David At 17:21 12/01/2007, you wrote:
