Refurbished Unimat SL for sale. 3
I have a Unimat SL for sale. It has been refurbished. The machine has been completely dismantled and cleaned. The spindle bearings have been regreased. The countershaft roller was fitted with new bearings (the old bearings were no longer usable due to lack of lubrication) A new tailstock sleeve was installed. The lathe chuck was dismantled, cleaned and reassembled with fresh lubrication. All feed spindles were cleaned and reassembled with thrust washers. The machine is driven by a 24 V DC Dunkermotor. The machine was repainted before reassembly. New PU drive belts were fitted.

Unimat 3 conversion 2
I've just finished renovating my Unimat 3. When I got it it wasn't in a good state, someone had tried to change it to a 24v motor using a 3 amp power brick, but had done a bad job. They had taken off the metal plate the hold the motor etc and replaced it with a small electrical box that flexed so I had to add a bracket to hold the motor. The drive was via a round belt single pulley and they had filed the lathe spindle to get the pulley on. I turned the spindle so I could fit a timing belt and fixed the rest of it up and used it like this until recently. I scrapped an FDM 3D printer that had blown the main board, so I took out the 24v 15 amp and used that with other bits I had for this latest conversion. I 3D printed a new housing for the 24v power supply and also added a new 3D printed hosing for the drive. It works really well now, more power and smoother. Photos of before and after. Lez

DB/SL bed bars to centre dimensions 2
I'm being a bit lazy but doing an accurate measurement seems like a bit of a pain... Does anyone have the dimensions (or a drawing) showing how the bed bar position relates to the lathe spindle (or tailstock!) centre line please? I've been looking through the files section and found the bar diameter and spacing but not how the bars are positioned with respect to the centre. I'm looking at modifying a Taig steady BTW and want to draw up the modifications that I will need to make Thanks in advance. Regards, Andy

English translation of U3 book, and looking for two other Emco publications 7
I ran the German version of that U3 book through Google Translate, and uploaded the English version to the Files section (might not be perfect, but it's pretty good). Thanks again to Herman for scanning it! It has some great info: /g/Unimat/files/Unimat3-BasicTechnicalKnowledgeAndPracticalApplication-ENGLISH.pdf Given how useful that was, I'll press my luck and ask if anyone has two other educational Emco publications: "Emco Unimat Basic Course Instruction Manual" or "Emco Programmed Exercises" These are listed in the bibliography of DJ Laidlaww-Dickson's "The Book of the Unimat." Foreign language versions welcome! And I can help get it scanned if you need assistance. Cheers, Joel

Pinol feed gear
The Pinol drive on my Unimat MK 4 had caries. It was already missing several tooth segments. There are a few suppliers online who still sell such parts, but the freight costs were too high. I ordered 1 pinion with 10 teeth from E-Bay. I needed a total of 2 sprockets for a Pinol drive. These are 10 mm long without hub and grub screw. The rest of the material was still available in the stock. The shaft was turned in the collet chuck. The pinions were drilled out to ?5 mm and reamed. All parts were joined together with Loctite High Strength and the two gear wheels were aligned with the teeth. After the adhesive had hardened, the transitions between the two gears were smoothed with a very fine needle file.

ER 16 collet chuck Unimat DB. 2 #db200
In my search for a collet chuck device for my Unimat DB, I have unfortunately not found what I was looking for. The problem is the ES collets, which are almost impossible to get. I have made my own collet device for ER 16 collets. I first pre-machined the basic body from 42CrMo4 heat-treated steel on the large lathe. Both the fit for the holder and the taper seat for the collet. The thread was turned in the same clamping as the collet taper. I then set the headstock of the Unimat to the collet taper and turned it on the small Unimat by only a few 1/10 mm. this way the taper runs with a maximum deflection of 1.5/100 mm. I bought the clamping nut from the Chinaman. You can find the pictures on my homepage. https://mueller-bruno.de/emco-db-200-1000.html

"Basic Technical Information" U3 book? 17
Does anyone have a copy of the book "Basic Technical Information and Practical Applications of the Unimat 3"? I saw it in the "HobbyProducts_(NeilsCompressed).pdf" catalog from the files section, but can't find much at all about it online. It seems to have only been mentioned once in this group. If anyone has a PDF I'd be grateful. Or if you have a physical copy, I'd be interested in helping you get it scanned. Thanks! Joel

Someone using U3 threading attachment? 5
I have a U3 and some of the parts for the threadcutting attachment. But I don't know if it is worth searching for the parts I don't have. I can't see any pictures of some U3 with this attachment mounted in the Internet. And no Youtubes either. Is it a attachment someone use? Is it difficult to use? I have seen homemade attachment for threading. Maybe be better, easier? Please give me some advise.

SL motor heats up and.. 12
Hi, These days I am having more time to get used to the Unimat SL I purchased months ago. I have started working on some new stumps for a watchmakers staking set, and After 5 to 10 minutes, the (SL original) motor heats up a lot, and then suddenly shuts down the house¡¯s fuse. It happens again and again until I quit and leave the thing alone to cool down completely. Any ideas about what can I do to improve this? TIA

Interesting turning technique 18
Watched a short Unimat video where the operator advances spindel instead of the cross slide to turn down a small part. Very efficient. https://youtube.com/shorts/OO0_LObYHh8?si=qcS9be79qkBnPgeP

Union Hacksaw Frame 3
I acquired an old Union hacksaw frame some years ago having a wood turned handle. I like the feel of the single wood handle. The saw frame is shorter than most modern hack saws but is very well balanced and is comfortable to use. In use it feels like a fret saw.
