In my case, I’ve found the U3’s original motor well adapted for the lathe… no on/off duty cycles such as with my SL. However, I did find it useful to adapt a second motor to the U3 milling column. In my case, I already had a Chinese sewing machine motor, essentially an oversize scooter motor, on hand. The extra power it provides has been welcome.

Friendly regards,
Alan

Doesn't look too bad. Light rusting on the bed can be cleaned off with a pot scourer - Scotchbrite or similar. That would do for most of the other rusty bits - then polish them up with a good wax polish. The painted parts will clean up with a damp cloth. As for extras, I would get collet holders for the headstock and tailstock, and a plain toolpost to use in place of the compound slide. Only fit the compound slide if you need it - it reduces rigidity.

I can suggest these things with full confidence as it's what I use on mine. The collets make accuracy so much easier - although the three jaw chuck on mine has a runout less than 0.001". Collets also give you more working space over the bed. A live centre for the tailstock might be useful, although I haven't used mine yet. It all depends on what you hope to use it for.

At some point I will be fitting a 24 V DC motor, as discussed many times here. I have the motor and I think it is an easy swap, but I might make up some new pulleys at the same time. I will use a speed controller as well, but I found on my SL I still used the pulleys most of the time for speed changing.

Does your photo show all that you have, or were there some more bits and pieces with it?

Better than the SL for turning - more rigid - but not as versatile. Although I use my U3 these days, sometimes I really need my old SL - but it's in Australia now which is not very convenient.

Absolutely! female M14 to male M12 (not M13). Sorry for the typo.

Just had this delivered:
The owner fell ill quite a while ago and can no longer use it so his son moved it on.
Now it's my turn to clean it up and get it working again, it is in a sad state but if all goes well I will replace one of my SL's with this one.
Not many parts came with this so will be looking to add to it at some stage.

Hello,

?

Doesn’t look that bad at all ? I’m guessing you’ll enjoy using the U3. One thing you might consider straight away is getting is a M14 female to M13 male adapter... Allowing you to use some of your SL accessories fornow (and even beyond).

?

Friendly regards,

Alan

Re: 3D Print of Unimat Logo

 

stl can be imported into fusion, as a mesh (i have just imported a 3d scan of a part I wanted to make an insert for, admittedly I didnt edit it (just used it to build a model inside))

Re: 795, 895 (etc) DC motors

 

I have been having trouble with some motors from China at work, where the power, voltage and current figures just didn't make sense, so I've looked again at the spec for these motors. I haven't found reliable information about these, but I found a very similar motor with detailed figures. At the rated power of 85 W, on 24 V, the rated current is a little over 4 A, which makes sense. This makes me very suspicious of the previously given starting current of 10 A. However the figures I just found give a stall current of about 35 A, so a power supply with a good cutout on it would be a good idea.
?
I think some of the people writing these spec sheets really don't know what they are doing.
?
The spec for the motor I found (Rotalink D5269-5030) is:
?
Voltage DC 24 V
Max speed: 8800 rpm
No load current: 1.4 A
Stall torque: 0.85 Nm
Stall current: 35 A
Max power: 195 W
?
At? maximum efficiency:
?
Speed: 7850 rpm
Current: 4.85 A
Torque: 0.1 Nm
Power: 85 W
?
This all looks quite sensible.

From what it looks like - the site is still there and some of the content is still accessible. However all of the HTML files appear to be MIA. I was able to access the content by grabbing some urls off the Wayback Machine at Archive.org.
Most of the site has been archived there. Appears the html went away sometime between Jan 2023 and Mar 2024.
I noticed that his last YouTube video is at least 2 years old.

Re: 3D Print of Unimat Logo

 

Thanks. Still have a long way to go. I get extremely frustrated, I mean chest pain level, with 3D software. I think I've tried 5 at this point. What I could do in PowerPoint with simple lines or delete seems to take a dozen more operations I try to memorize as I go. I've about given up on trying to modify work that others have done. I did this in the Bambu Studio.
