Topic tags/keywords: question tablesaw manufacturer mystery branding union machinery jet jet jcs-10

This is my first post and I am glad to be a new member to the site.

Last year I went to a auction of the estate of an older deceased cabinet maker. I acquired this man’s table saw, which reads 1991 on the manufactures plate and is in great shape. The manual, that was with the saw is for the Jet JCS-10. In the manual, instances of the trademark JET logo, where it appears in photo layouts are literally been blacked out. Whoever blacked out Jet used a permanent marker, as the ink bled through the paper. Interestingly, where JET is used in writing, as in the product description and parts lists, there is no blacking out. Here is the mystery, this isn’t a Jet saw.

The saw is all but the same in its manufacturing as the Jet JCS-10, as described in the manual, with some key differences. The saw has no JET branding. Where the Jet branding would read on the front of the cabinet, a worn sticker reads UNION MACHINERY. Below the branding the plate stamps read model MATS012UAM and serial no. 029240. The motor specs, 2HP, 230 V, 16 Amps, 1 phase, are the same as the those listed in the Jet manual. Another key difference is in the cabinet’s shape. The JCS-10 has a square cabinet and mine is square on 3 sides with an angular protrusion in the front, where the control box lies. It is also gray, rather than the blue of the original JET JCS-10.

Everything else seems to be the same on the surface. I started digging into the parts list because the fence is not firm. I have to replace the eccentric cam and foot to make the fence hold to the rail. The foot mechanism happens to be the one thing that is different in the make up between this Union saw and the one in the JCS-10 schematic.

Does anyone know anything about a company called Union Machinery? Is this saw some kind of knock off? Did Union Machinery make a saw and become acquired by JET? I have found a Union Machinery from another era, (early 20th c. and a Union One Machinery that makes machine tools today. Union One Machinery makes production machinery and is out of Taiwan. I am perplexed.

Many, if not all, of the older Jet saws were made by Mao Shan in Taiwan at one time, as were many other brands….some major, some obscure. It’s very possible that you have a Mao Shan made saw.

A pic is worth a thousand words.

knotscott,

Thank you for the information. This makes a lot of sense considering the first four letters of the model MATS012UAM. I have emailed Mao Shan to see if they can help me acquire replacement parts/ manual. I will post a photo after work today. Thanks so much for your help! I had not heard of this company, and although I am in my mid 30’s, am new to woodworking.

I’m not familiar with the Union Machinery name, unless it’s the same brand that used to make hand planes 75 years ago. It’s not unusual to find off-brands that are nearly identical to some of the more recognized names. When you post the pic, it should give us some more clues.

Without seeing it, the 2hp motor could indicate that it’s one of the early hybrids. If the inside looks anything like what’s pictured below, the Jet manual could be a valid cross-reference for parts. Does the drive system consist of two belts? Another note worthy hint would be the existance of two connecting rods as an arbor carriage between the front and rear trunnion brackets.
