I just finished working on my GS1200 which I bought with a rewind / forward stopping problem. The problem was the nylon/brass gear directly on the motor shaft. I was going to buy one from Leon Norris who was very helpful on the phone. But, I couldn't get the tiny set screw loose on the brass sleeve to remove the nylon gear which was cracked. So I did the next best thing. I carefully removed the gear of the brass sleeve, then using super glue gel, glued it back in place. I clamped it to keep the cracked closed. Then I let it set for 30 minutes. The important thing is to make sure when glued the crack is completely closed. If it is even slightly open the cogs will not mesh. After re-assembly it works perfect. I wanted to pass this on for other members who might have a similar problem.

And now our feature presentation!

Not to jinx you Pat, but Nylon is notorious for being hard to get adhesives to (umm)...adhesivate!

-especially over the long haul.

Same happened to mine last year Pat and did the same as you. It didn’t last although you probably did a better job than me or perhaps the angle of the split may play a part. Was lucky in the end to find an Elmo spare part and its been going fine ever since.
Yay!

Well I used the gel because it spreads flat creating a much better bond than the regular liquid super glue. Plus , the crack was at the exact angle of the cog. By removing the gear and filling the knurls in the sleeve it gets a much better adhesion or as Steve says it "adhesivates" better! If it lasts fine, if it doesn't then I will buy a new gear. However, they are 50.00 brand new. I'm always experimenting to find a less expensive way to repair or replace something. RE: The halogen bulb conversions I do on the old projectors I rebuild. It makes the hobby more fun. [Wink]
