When this issue came up I went ahead and ordered an adapter from Packard ($16.90 to my door).

I did this because I have two other adapters which take the shopsmith to 1-8tpi size and their adapter gets me where I want to go in that manor.
The one I ordered is really a PSI model which I guess you can order from them.
The adapter arrived today so I went out to see what I could see. I'm often not so happy with PSI items so I was thinking this could be a bust but was pleasantly surprised by the results. Yes the part is made off shore somewhere and the machining and feel reek of that but it is the function that I was most interested in. I paired the PSI adapter and gave it a test run, well first I re-prepared the wood to get everything back round and square. Then rotated the fixture 180 degrees, it was far better then when doing so with my make shift bolt, and in fact useable.
Next I paired the parts with my other 1-8 adapter from Best Wood Tools. The Best Wood Tools one is made in the USA, very nice workmanship and finish and has the set-screw at the "shopsmith" angle. Yes it costs a lot more but it is a much better choice if you can afford it. Testing this time was about as perfect as I could imagine it! A big thumbs up for this set up, but it might not be the most cost effective with the Best Wood Tools adapter depending on how you value things.
Here are a couple of pictures that might help you see what I've been writing about.
This is the adapter that allows 1"x8tpi lathe chucks, face plates and the like to mount on the shopsmith.

The adapter I purchased from Packard then attaches to the 1"x8tpi part and gives you a 3/8" x 16 tpi end for doing bottle stoppers and pendants or attaching the indexing and off set adapter from Ruth.

Put it all together and you have this.

Here is a side by side of the two 1" x 8 tpi adapters, note the Best Wood Tool one is the shorter unmounted one.

At this point it is pretty safe to say the problem was with the bolt adapter I made. While it works for turning bottle stoppers or things that are not indexed it is clearly lacking for the purpose I tried to use it for.
Keep in mind I have also ordered the new mandrel from Ruth, should have that may be tomorrow. I'll keep posting as I check this one out.
I have also as Rick to make me one that is just for a shopsmith. This will be the a direct fit on the shopsmith and have the correct angle set screw. When that comes in I'll have a look at that as well. This is an x-ray view of what it will look like.
