Tried again. I think I was able to resize it.

Now show us the part to the left between the pipes.

And, well it appears the whole set-up is on the other side of the headstock so a whole picture is of interest.

So how does that differ from the normal setup?

The tool rest bracket is mounted in line with the rotation axis rather than off to the side.

Question for the original poster: Why did you mount the bowl on the left side of the headstock (above the auxiliary spindle)? Normally, turning is done on the Shopsmith on the right side of the head stock so that the tool rest can go into the carriage as was intended.

If you have been turning on the left side of the headstock, there's no carriage and thus no place to put the tool rest -- except perhaps the holes for the SPTs (Separate Power Tools). This might be feasible, but it certainly isn't as intended and the geometry of the tool rest would probably not work as intended, as you have found out.

I know on stand-alone lathes sometimes there is an advantage to turning on the left side because there is no lathe bed there and thus you can increase the swing of the lathe. But on the Shopsmith, there is no advantage because the way tubes extend on both sides of the headstock.

Accordingly, I think I would remount your bowl on the correct (right) side of the headstock and use the carriage to support the tool rest and try again.

This entire thread is about the fact that what he is trying to do will not work using a typical setup using the carriage mount.

You may be correct, but that's far from clear to me from the thread. He never once mentions the carriage and there are no photos of his original set up and the problem he experienced.

Pictures, no. Description, yes. One has to visualize what he is describing and what he has described as a 'solution'.

With the tool rest support bracket mounted in the carriage, it can only reach towards the bowl at an angle. The bracket is 'sloped' and that lower portion will contact the rim of the bowl as he attempts to position the tool rest INTO THE BOWL. By positioning the bracket in line with the rotation, the bracket can extend into the bowl further before it contacts the rim.

Now why the back end mount, I do not know unless the needed 'reach' is less.

Give him credit for original thinking!

I have two shopsmiths one has a dewalt planer mounted to the end and I use this one for most of my turning with the normal shopsmith set up. As I progress with a bowl I find it is difficult to get the 90 degree set up around the bowl to do the sides and bottom of the inside. Tool overhang becomes a problem and it becomes unsafe. After I finish the outside of the bowl and most of the inside I move the bowl to the other shopsmith away from the carriage end allowing me to get the bowl very close the my homemade tool rest resulting in very little overhang of the tool. It is much safer and I have less in my way when finishing the inside and bottom of the bowl. My home made tool rest Is on the left end of the shopsmith where I normally mount my band saw. I approach the bowl from the end as opposed to the side. I get better light and fewer things in my way and a more solid tool rest. I have since cut off the pipes that fit in the tube holes allowing more room to move the shopsmith tool rest. It will almost go 90 degrees if I need it. I have tried to post more pictures but can't seen to resize them correctly.
