Re: set screw of blade arbor
Do not overlook the need to rock the wrench so the setscrew comes to contact the flat at the center of the tapered flat.

Brass Tipped Set Screw
If Shopsmith has determined, for any reason, that the original arbor set screw (222458, $0.80) should be replaced with a brass tipped setscrew (516240, $2.14), it would sure be appreciated if they would notify the customer base. A simple post here on the forum would reach many of the users but it certainly would not reach the majority.

Re: set screw of blade arbor
Here we go again. 
I wasn't going to get into this but just can't resist. Dusty, you are right on point. There have been thousands and thousands of arbors sold by all the companies who owned the SS brand over the years without brass tipped set screws. Has there ever been a problem. I don't think so that we know of. At some point SS started selling 5/8" saw arbors with brass tipped set screws. Apparently, that is the only arbor that has them so why? No logical reason other than some engineers idea of a better way. Is it a better way? Maybe, but how about when the brass tip wears out (and it will) after 30+ years? What is left? Who checks their set screws on a regular basis? Maybe it should be a maintenance check. 
If it is such an issue as Ed seems to think it is (I honestly do respect your opinion Ed ) then why are not all new arbors that way? We have had non brass set screws on Shopsmith's since 1947.

Re: set screw of blade arbor
It is not my opinion that counts it is shopsmith opinion that counts and they made the change and I believe they did it for a reason. You don't add more expensive parts unless you have a reason.....
You can't use the brass tip ones on other arbors or for that matter on other places where a shorter set screw is needed. Simple not enough room for the brass tip and the number of threads you need.
You either trust shopsmith on this or you don't. Just that simple.

Re: set screw of blade arbor
Like most topics, we have had this discussion several times. That's a good thing.
Here are a couple of them:
http://www.shopsmith.com/ss_forum/begin ... t8249.html
http://www.shopsmith.com/ss_forum/maint ... 13948.html
You can also do a Google search on:
Self locking set screws
You might get some ideas there. Some of those have a nylon insert through the body of the screw that sticks out a bit farther than the threads for more friction.

Re: set screw of blade arbor
Just a comment for what it's worth. Reminds me of the thread concerning the dimensions of the SS miter bar. I commented then I thought they probably used "Bastard" dimensions to keep a captive audience and this might be another example??? I have been using box store Allen Head set screws for some 65 years and don't recall one coming loose that was properly tightened.

In the past they used ones with what are now non-standard hex socket sizes(to keep them 5/32") but I believe no one will make them any more. Some screws are unique but they serve a unique purpose.

Re: set screw of blade arbor
If by "Bastard" you mean "non-standard", I do not believe there are any used by Shopsmith.
Now brass tipped set screws are not available everywhere that you can purchase set screws but I suspect that is due to "low demand" (not worth maintaining inventory). I do not consider "brass" tipped set screws to be "bastard".

I believe that the 47/64's size of the miter bar was the standard when the 10E's came out.

Re: set screw of blade arbor
you guys are missing the point. I am not saying SS is using "Bastard" set screws. I am merely making the point that using a set screw with a brass tip is unique as far as I am concerned. Or in other words something to sell. The only function I can see is that the set screw with a brass tip will not "Marr" the shaft it is setting to. Possibly the brass being softer may grab the steel shaft better than steel but that is debatable.
