Members ke6cvh Posted January 10, 2018 Members Report Posted January 10, 2018 OK, on the threading. Here is a video in Spanish that shows the threading. Really doesn't need to be in English as it is shot pretty good. I see the 460/13 in this video uses a curved needle. Our Merrow and our 39500's use curved needles. Our US39800, Juki, Brother, and Singer 1842's use straight needles. The advantage to a curved needle like yours is that the needle enters into the stitch triangle easier (it is much easier to adjust loopers if ever needed) and curved needles are more precise as well as likely faster but what I do know for certain is precision needle placement and ease in adjustment. The trade-off is that the needles are more expensive and have to be ordered off the net. I prefer curved needles most of the time. If you search youtube you will likely find more videos showing the threading. Best regards, Mike
Members ke6cvh Posted January 10, 2018 Members Report Posted January 10, 2018 forgot to ask...what is the serial number? It is pretty easy to cross date of mfg. with most Singers based on serial numbers using the ISMACS website. Not all industrials can be narrowed down really well but typically it can be found. For example, our 112w-139 and 112w-140 both are mfg. in the 40's but I can't nail down the exact year because "W" machines (industrials) are not as easily found all the time. Just curious but my S.W.A.G. is that this machine likely is around 1960. Would be fun to find out. Best regards, Mike

Members ke6cvh Posted January 14, 2018 Members Report Posted January 14, 2018 it is likely going to be on the cast iron somewhere. It was common to have an oval shaped piece in the casting. You can then go to the ISMACS site for serial numbers and try to cross it to a date. The 460 is a later model preceded by machines like the 246 series. That is why I guessed it to be around 1960 time frame but that is only a S.W.A.G. It is certainly going to be a self oiler being it is capable of up to 6500rpm. I do not have personal experience on this machine but the basics are pretty fundamental. Anyone used to 3 thread machines would certainly be able to figure out fairly quick the threading. If you have to break the case open (unlikely) you would be able to easily make a new gasket for it and seal it again. If it is like a Merrow there will be a plunger pump on it. The Merrow m-3dw-4 I have here actually has two plunger pumps and a filter but I did not need to break the case. It was semi-frozen upon receipt. I moved it back and forth to free it up. I then filled it with kerosene (light lubricant) and ran a belt off the chuck of my Dewalt 10 amp drill for a while. THen drained and put Juki M oil in it (light machine oil). The manual called for light turbine oil but my experience is this is ok. The manual specifically stated to not use stainless white oil (mineral oil with possibly some inhibitors like the Shell Diala used in power transformers). On the other hand our Union Specials use mineral oil. In the end an older machine like this would likely never be run at 6500rpm anyways and taking it down a notch or two to 4-5k rpm should be just fine. I see loopers and knifes on eBay for this machine. I had an old guru teach me the trick to sharpening the upper knife. It is done in one direction only. We did this to our Merrow before we got new knifes for it. My wife was using our Merrow and our Brother the other night. She now only uses the domestic Juki for light work and not as often. I'm happy to see her using the industrial sergers more and more. They are true work horses of the garment industry. Looking I see there was a "K" on some models. The K is for machines made in Scotland. The W's were in USA. Best regards, Mike
