JPG, I'm not exactly sure what you mean by straighten the arm. What I mean is; do the arms need to be brought closer together? Is it the difference between the arms that will cause the new pork-chop to fail? I'm not sure, confused:

The wear shown in your pix shows that the worm gear no longer aligns with the center of the porkchop. One of the arms that the roll pin passes through has moved thus allowing the skewed alignment. The arm usually opens up the spacing and allows the porkchop to slide to one end.

The arm needs to be restored to its original position. This usually requires squeezing the arm back towards the other arm(the arm spacing = the porkchop width at the roll pin).
I prefer doing the squeezing with a vise so as to not 'slip' and over stress the arm. The amount of 'motion' is tightly controlled with a vise.

Thought, I would bring everyone up to date concerning the repair of the quadrant. I tried to locate the allen screw mention locally but to no avail. The only way to get the screw is to buy a hundred at a time. Have made contact with Bill Mayo and am waiting to hear from him regarding cost of the allen screw. I like the idea but it seems do difficult to attain. Was wondering why Shopsmith
does not carry a repair kit. I understand too that Bill may not be feeling well. Hope he is feeling better as most of you do too. This probably should be under a new thread but what the heck. thanks to everyone for their help.

Allen screw??? I'm confused. Are you talking about the fix for the problem discussedhere?

If so, this post by Bill Mayo gives you the details forhis fix.

I know about the fix Dusty. The problem is that the Allen screws are not available in the 2 1/2 length just anywhere, I've done my looking around. As I stated in my previous post the screws can be bought but only by a hundred. That can be pretty costly when you only need a few. And my question again: is why does not Shopsmith offer this fix it kit for the quadrant?

Bill's quadrant fix and the parts that he uses are ideal. The reason why the bolt is hard to find in a hardware store I believe is because it is shouldered.

A shouldered bolt is not absolutely necessary. Here is a photo image of the quadrant in one of my machines. It works fine with hardware available at Ace. Also, it does not need to be done with an "allen head bolt. There is plenty of room for a hex head bolt

Thanks, Dusty, I thought, that there had to be a shoulder bolt. Bill may have already sent the Allen screw kit. Have not heard from him, so don't know.

Any one who needs the free bolt kit, please send me an Email. My computer Windows Email had problems for the past month or so after switching to Verizon FIOS but believe I finally solved the problem by switching to Google Chrome as my Email web brower.

I do buy the bolts by the hundred so it is a very small cost for me to offer the bolt, star washers and nylock nut for free. So far, I am into my third batch of a hundred bolts with noone having any problems with using the bolt for the past 8 years. Hopefully, I can interest some of these Shopsmith owners to check with me for reconditoned parts and service when they have a need. I include a instructions on how to use the bolt kit and set the initial high speed adjustment.

I believe they do not because like bearing replacement, 'they' consider it beyond the typical mechanical skill level(tools) of their customers.

Within this forum(and some others?) you will discover 'alterations' or 'fixes' that attest to the fact that that assumption is not applicable to all who frequent here.

The unavailibility of the screw attests to the slow demise of true hardware stores. A shoulder screw is 'better', but full thread will work as Ed mentioned. I prefer two nuts(jammed) to the lock washers. The nylock nut in Ed's pix is another good way to ensure they stay tight.(the nut(s) - the porkchop must be free to pivot between the arms).

Thanks for the input Guys. It is appreciated. Left to my own thinking, I can get into a lot of trouble. These forums sure helps to put things into the right perspective. thanks again!
