Thanks for the pic's of the Nelson, I have a similar one I got a while back. As far as a price, I was thinking about selling mine at the shows this winter, I was going to ask $500-600, I would be happy if I got $500 for it. Tim

Cool old Nelson. I would love to find one locally.

glennz01, not sure, but I think that Coos Bay Ironworks manufactured the Nelson Machine Works saws. Read on this website that they were made in the '50's. "Nelson Machine Works-Coos Bay Iron Works were founded in 1888 and may be the oldest and biggest machine works left in the USA. I understand they are still operating, but as a working museum. Nelson made a variety of saws, grinders, and combo units around the 1950s that were built to last. The highest serial numvber I have run across is 89." Source: tomaszewski.net/Kreigh/Minerals/Homemade.shtmlHere's the Coos Bay Ironworks website: Maybe you could contact them to find out more about your saw? www.coosbayironworks.com/

Looks like it could be an old sewing machine motor. If the right angle drive will come off, first try turning that by hand. If it won't turn by hand, it could be something as simple as dried grease. Pull the drive apart for a good cleaning and new grease.
On the motor, what Stephent said would be correct. Clean between the commutator segments with a piece of sharpened wood. Don't use metal for this job. Also polish the commutator with some very fine emery cloth, being careful to remove all of the dust. If the brushes are worn down very short, replace them. Any sewing machine repair shop should have replacements. Replace the power cord with a 3 wire grounded cord. The ground wire can be attached to one of the screws holding the motor together.

Just to make this thread a bit more complete as a source of Nelson's, here's a thread that has several sources of info, and photos of saws owned by Beefjello and Orygone. These saws were built solid. The vice and sled on my 12" weighed 30 plus pounds when removed from the saw. I need a stand and a blade shield for mine to make it original but will probably have to fab both.

I'd take it to an electrical shop and have someone who understands motor brushes, and windings look at it. It may be simple but not fixable in the hands of the innocent (myself included so no insult intended). I too want to see that saw. Don't discount oil until you run it with oil. Its just so handy to not have to worry about rust and it keeps my hands smooth. Tom Yuppers,I use mineral oil,in my saw,works like a charm... As for the old motor,do you live in or around a "farming" community? If so start asking some old farmers if they have any electric motors sitting around,some would let them go cheap..

You might look into getting it rewound.

Probably needs more than that... the manufacture said they no longer have the plans for that motor also.

Here is a Nelson saw for sale locally in the NW where lapidary equipment is generally lower priced. The price on this 18 inch saw at $1500.00 is not at all out of line. portland.craigslist.org/clc/art/4609820657.htmlI sold a 16 inch Nelson saw to a member of this board for $700.00 a few years back. He brought me several buckets of very nice rock as well. Nelson saws are the Rolls Royce of rock saws IMO, truly built to last forever.

First thing I did with mine was to cut and install oak jaws, the jaw liner material and the inconvenient feed engagement lever were the only downside to the nelson IMO.

I hope to get one of these in the workshop eventually. I always hear they are built to last.

Ok, i have seen online that one like mine 12 - 14 inch blade that is not running goes for $2,200 but we all know how trusting online like things are... (well some people see the asking price and think they have a small fortune)
It is the only nelson like mine i could find for sale to get an idea.

i am considering purchasing azrockgeek's Nelson which is a 14" for around $500. slab saw prices are all over the place. the forums will be more of an honest good price rather than ebay or craiglist (at least here in California).

A Nelson 14"? Sure it's not a 14/16? The Nelson 14" I had for a short time was a different kind of open saw, ie not in a box. It also had a grindstone on the other end of the arbor.

Not sure if you can read the tag or not. Not a 14/16, did not verify this with a measuring tape as it has never been in question. LOL

I believe he posted a pic of it in this thread. Basically means mine can run a 14 or 16 inch blade right? (because I put my 16 inch blade by it for comparison and it looks like it would be tight). I also think this thread has turned slightly away from my saw and more towards others hence the confusion I think.
