Nice lathe and interesting mods, I have always liked the Sieg SC4 lathe ever since they were first introduced and offered by a few other dealers in the UK before Arceurotrade started selling them. I have a few larger lathes from China and the UK which I have owned for many years now, but I am thinking of down sizing a little and the SC4 from Arceurotrade is possibly at the top of my list. One other thing to check, if you haven't already, is the pair of steel gears inside the headstock that drive the spindle. These are sometimes assembled at the factory with rather dirty and grimy looking grease, often also contaminated with metal swarf. So a good washout and rinse then fresh lube will make them last a lot longer, and sometimes quieten them down a little. Anyway, I hope you are happy with it and it serves you well for many years.
Thanks for that - I will have a go at the headstock gears in the near future, and hopefully make some improvement. It's not too noisy, but it is more so than I had initially expected. I'm really happy with the lathe, and it's a good match for my SX2.7 mill, also from Arc.
Hey nice video! I have the same lathe with a different name which it is jetco jml-3s. They are exact same lathes. However, I have a problem on my lathe nowadays. I made lathe work a couple days ago and turn off the lathe and then turn it on again about half hour later but the fuse that on the front panel which is above the green light pops out. I replaced the fuse with same one but pops out again. I tried 5-6 times but each time it just blew. So I've checked the control board, servo motor, screen boards etc. I didnt see any damage on them, and even the fuse on the control board was working. So, do you have any idea what's going on my lathe? Thank you.
Hi - I have no detailed circuit diagram / schematic for the lathe control system, so I can't offer any useful suggestions. However, previous experience with other equipment tells me that electronic faults are not always evident in a simple visual inspection: components (ICs, capacitors etc.) can fail internally without any external sign. Sounds like a call to the supplier is in order, but I fear they may recommend replacing the entire control board - $$$ :-(
Hi Steve - I was wary about how the SC4 would perform straight out of the crate. In practice, for my everyday use of making simple mic stand adaptors and the like (not particularly tight-tolerance stuff), I have found it quite usable as-is. Mindful of the significant time and effort I had expended getting the tailstock aligned on my previous, smaller, lathe (CL300M), I've taken the 'ain't-broke-don't-fix-it' approach in the case of the SC4, and have opted to defer any finer setting-up till I have a more dimensionally demanding project... Breaking tailstock bases sounds like really bad news :-(
@@reqordist Yes, I've made a lot of parts that were not to tight tolerances but was frustrated on smaller/longer stuff where I was constantly turning tapers. I have (yet) another tailstock base on order from Axminster but they have said it takes 6 months to get spare parts for their lathes. I bought the last one from Arc and had a friend mill it down to suit, but the adjustment lugs inside are so brittle that they snap so easily when turning the grub screws.

Interesting video. How precise is this lathe? Does it have any play? Did you measure the concentricity error?
Finally got round to measuring runout on the spindle chuck registration boss - measures as 0.4 thou (10 um) total - that'll do for me!
A carriage lock mod is also nice.
I agree - will look at that soon - just using an allen key on the locking screw atm.
Any problems with tailstock alignment? I've spent hours trying to get mine adjusted and the bases keep breaking!
