Glad you got it rolling. Great tool once you have it set.

Resurrecting this thread. After a number of months, I finally got around to setting up my squeezer with a base and regulator but ran into a problem. I bought my unit without yolks since I have a full assortment of them already that I use with my pneumatic squeezer. When I tried to fit my yolk to the new squeezer I found then holes were slightly misaligned.

I sent the unit back to the manufacturer and they said their yolks fit perfectly. However, they manufacture their own yolks so it makes sense that theirs would fit.

So a couple of questions:

1. When you bought your unit, did you also order yolks or did you have existing ones?
2. Did anybody else have this problem with their existing yolks not fitting the Numatx squeezer?

No problems with mine. Lines up with all my other yokes easily. All my other yokes are CP214 style, as I think is the case for most but not all. Is it possible that the yokes you have are not the 214 style?

I bought them from Cleaveland Tools starting in 2017 and adding as I built. I called them a while ago to confirm they are using the CP-214 standard and they said they were.

I found a manual from Chicago Pneumatics (the CP in CP-214) that had some detailed dimensions for the yolk interface to the body today. I'll do some measurements on my yolks to see if they match.

The pneumatic squeezer I bought from Cleaveland has a ram that is a loose fit that can accommodate some misalignment, but the Numatx design by necessity can't have that slop in it.

It is hard to tell anything from the photos. I have an Avery hand and XX Pneumatic, I got an extra pair of pins and one set is a tad larger and much harder to get installed. You might measure the pins to be sure, but it sure sounds like a bad tolerance stack up.

Do you need pin distance numbers from others?

Same here - hasn't been an issue.
