This Saw has served me well over the years. The bearings are not all that are needed to get it restored. Unfortunately I've discovered that this Saw has some other issues. It will need to be taken down an disassembled, cleaned and reassembled. In this Ordeal I have to wear all the hats and NONE of them fit very well, to accomplish this. Is there or would there be someone that can give this SC the procedure to follow to take down the machine, and to properly put things back together & aligned. Any an all suggestions, instructions & assistance with this matter would be very much appreciated. Thank you very much! IV 62-66

It's not terribly difficult to restore one of these saws. I bought one off of Craigslist a while ago and it was in a lot rougher shape than I thought. Just be sure to take pictures as you take things apart. Lots of pictures! But there aren't a lot of parts really. The link that Robin posted will be helpful. You won't need a lot of tools, but I did need to buy a cheap 3 jaw gear puller set from Harbor Freight to get the pulleys off of the arbor shaft. I replaced the pulleys and the belt since they were worn and bent. And the small bearings on the carriage are same as those used for skateboard wheels, so it's a good source. The arbor bearings can be found locally or on eBay. I was lucky and didn't have to replace any factory type parts, but I hear that Lortone is pretty good to work with if you need something like a new arbor. Aligning the blade to the carriage was tricky, but not all that hard...just took some fiddling. Hope that is helpful to you. Just go slow and you'll be fine!

This SC had a senior moment and decided to disassemble the whole unit. In a way I'm glad I did, but who would of thought to take pictures  . The arbor bearings needed replacement as well as the carriage bearings. Also I will need have to rethread the channel carriage, as it has become sloppy, and also possibly the vise carriage. A couple of things if you will an are able to recall? Please keep in mind that my unit is an older LS 12 and some things have changed on the later models. What is the best way you found to remove the vise carriage? Also the carriage ways? And then the setting of the carriage bearing to the carriage ways? There is also the matter of the threaded feed rod removal and re installation. These were a few things that I fooled around with and didn't go all that well. Thanks very much for taking the time to assist this SC. One consultation is that this will probably be the last time I will have to do this, if I can get it close. Kindest regards ....

Hi Ivan. Best way to learn a saw is to take it apart I think! But, I'm no expert in the matter, so buyer beware of what I say. On my saw, I didn't have to remove the carriage ways, they were sound. Nor did I remove the threaded rod for the auto feed. It was in good shape and the bearings on either end of it appeared to move freely. I did run out and look at my saw, it's an older LS 12 as well, so probably similar to yours. If you want to remove the carriage ways, it looks to me like you can just loosen the jam nuts, then back out the bolts from the brackets on the ends of the ways. I think they would just come out. If I'm remembering correctly, I had the saw on its side when I took the carriage and vise off...the bottom pan removed. I loosened and removed the bolts holding the carriage bearings, and took the bearings out. There is a spring holding the split nut that grips the threaded feed rod. Take the spring off and open up the nut. I think the whole assembly will just come off as it pretty much just sits on the ways. I don't know if that will help or not. I'm attaching a couple pix that might be helpful, one is the carriage way bracket with the jam nut/ bolt/ and bracket that I mentioned earlier. And the other is the back end of the threaded rod assembly. Attachments:

The one I have did not have or come with the hinge. Thank you for sharing. IV |

Ivan, I happened to find a picture of the bottom of the carriage/vice assembly of my saw that I took when I was taking it apart and cleaning it. It's pretty gummed up, but maybe the photo will help you a bit. Attachments:

It's pretty gummed up, but maybe the photo will help you a bit. The picture has helped out very nicely. The bottom looks somewhat like mine when I decided to take it down. In the process of putting things back together an in order. I don't think that I'll have to replace any major parts either. So far ... Arbor bearings and vise bearings. Will try to post a final update when I get it back together and take a cut or two to see how the alignment went. Thanks again for taking the time to post the pictures and your input was appreciated. I think you will like and get pretty good service from your rebuild. IV |
