Hi all,

In my question to produce fully punched tape, I acquired this LPR35 BRP unit. I hope to replace the hanging chad unit in my ROTR. I have NOT yet installed this on the ROTR base, I’m just getting familiar with it first.

It appears to have some modifications for tape feed out. Perhaps some automatic tape feed out control as might be evidenced by this solenoid. Remote? Interfering? Non-interfering?  Blank tape feed out?

However,  manually actuating the solenoid does pitifully little, I can’t imagine how this could do anything. Maybe once things get in motion through the motor, this will do more?

My current ROTR’s LPR has a lever which I believe is manual LTRS feed out function.

There is this hexagonal attachment on this shaft which seems to be possibly related

Now for the problem. As I picked up this unit with almost no force on it, this piece broke off.

There were two screws that attached it to the hexagonal shaft.

these two screws look like they sheared off, but I suspect they were previously broken and just sitting in the holes with some grease. I can’t see how what I did could shear two screws, but alas, here we are.

here is the rear of the shaft.

I plan to order replacement parts from Mr. RTTY but I wanted to understand what I’ve lost and what I’ll gain from replacement parts.

Anyone familiar with this set up on the LPR35? What do I have? Once I replace the shaft, how do I actuate that solenoid? AC line voltage? Dc voltage?

Any pointers greatly appreciated.
