Yet another setback.


A few days ago I really thought I had all of my bases covered, and that I was ready to install the mechanism into the cabinet.

But, sadly, once again I was wrong.

So what's the issue now? This:


That's a record sitting in the Magazine (as seen from the rear of the unit), and the record hits the Gripper Arm when the Magazine rotates! Yes, the Gripper is fully open, it is not damaged (it has the same dimensions as the other ones I have), the Magazine is in the proper fore and aft position (actually, it's not adjustable), the Gripper Housing itself is not damaged.....

From a previous post you may recall that I swapped Gripper Housings a few days ago, and I've been comparing critical dimensions between this unit and my spare unit/parts unit for a couple days. So far I've come up empty.

So, here's what I'm up against. On the old/parts unit the Gripper Arm seems to have equal gaps between the front and the rear of a record, as things should be.

* Front gap of (roughly) a 3mm on the "parts" unit:


* Rear gap of (roughly) 2mm on the "parts" unit:


Compare those numbers to these:

* Front gap of (roughly) 5-6mm on the restored unit:


* And rear gap (or lack of gap!) on the restored unit:


I really don't know where the problem originates, but all of the dimensions I've compared between the two units are identical. In fact, I've checked so many things that I'm starting to think I messed-up something when I reassembled the Record Magazine, so tomorrow I'm going to swap them out and see what happens.

(I was so close!)
