So I just installed ball bearing swivel set screws on the blocks... didn't really notice a difference. So if you were wondering, probably not worth the cost.

What I did notice was that the front screw caused a huge shift in position. So I tightened the side screw to finger tight, then the front, then tightened down the side, then the front, and I have the nozzles pretty close. I'll try a dual print tomorrow... or whenever I get around to getting the QR extruder up.

Not sure what you are saying you did. Can you show a picture?

It's basically a set screw with a ball bearing on the end.

If the screw size was much larger, I could use a better option, a set screw with a swivel tip that has a flat base.

I actually found a set screw with a ball bearing interface with the screw end and a flat end interface at the other end. I replaced my homemade "cylinder" screw solution with these. Big downside is they are way expensive. I got 4 for $43 -- including shipping. $22 for the shipping from England as they only ship FedEx 2nd day.

I haven't played with them yet. I will report back on how they work.

I ordered: Screw Clamp Pad - Plain or Serrated (WDS 652-2005) from WDS Component Parts Ltd.

intrigued, lets us know how it turns out, so these are M4's?

these might work with a new tap job:

Yes, M4. Not sure about tapping them and then using that thumb screw. The reason is that there is very little metal available to thread and it looks like that swivel pad uses up a lot of threading. That is one reason I dumped my own method and went with the new ones when I foudn them. I keep the majority of my threading and also get the swivel clamp.
