Shopsmith Forums

This is weird while at the same time interesting. Who originated the joint-matic and who now owns the rights? From what I have just read, it seems that Strong, Delta and Shopsmith have all had their fingers in this pie.

Now we have this individual, who reports to me the son of the original designer, contemplating a resurrection.

Unless he does a major redesign (or has permission from the current holder of the patents) I don't think he can do that. How long do patents remain in effect? The answer to that question may say it all.

Until 1995, patents lasted 17 years from date of issue. At present, they last 20 years from date of application, IF you pay your maintenance fees.

The joint-matic was available from Shopsmith when I bought my 510. From that, I conclude that the patent rights that Shopsmith had (if any) would have expired.

Once issued, can patent rights be extended?

BTW - CDR38 - I seriously doubt that there is a market for a new version of the joint-matic.

An original patent cannot be extended. However, improvements to an preexisting patented design can also be patented, and patent protection for the improvements (only) can stay in force for another 20 years.

A simple Google of Joint-Matic brings a lot of information. I also did a Google "image" search and got a small batch of pictures.

I've heard great things about this tool. The control is supposed to be great. I haven't used it, but from a recommendation, the thing is worth getting your hands on. I've seen some come up on ebay but the shipping was a bit much. I'd like to see where this thread is going and maybe someone who owns one can do a YouTube of it in use. Supposed to offer fine control of the attached router very much like a horizontal milling machine, kinda.

I think some of the responses this poster received were nasty. If they were asked to do a such a poll and do it in confidence I see no reason to be so nasty.

Frankly I think doing a poll on Shopsmith forum would probably only result in opinions from existing owners of the product. And without more information most people that are unfamiliar with the product could not begin to give an opinion.

I think the question was poorly stated and that might be the reason it was rebutted with such nasty answers.

I'm of the opinion if someone was thinking about making my woodworking easier and asked for my opinion on the product I would be happy to answer them no matter who they are. But they would have to tell me what the machine was, how it worked and how it would save me time and approx price to get a reliable answer.

Question as stated was like asking if I would buy an Estwing hammer. For everyone that ever owned one they would probably say yes. For those that never bought one they would probably say it depends on price, warantee, looks, material it is made from, head style and etc.

He missed a VERY important response in the survey. "I don't what a joint-matic is" That's me so the other options don't apply. If it follows the trend of so many other wood working tools/gadgets, it will most likely be out of my price range for the foreseeable future.

Nasty comments? What nasty comments? I must be reading the wrong forum.
