Keystone Model K100G 8mm project issues

[Greg Haxton]

I picked up a Keystone K100G 8mm projector the other day. But I have am experiencing issues with the forward drive on the machine. Reverse works fine but the forward spins but does not seem to catch on the cogs and turn. I was wondering if anyone has run into this issue before. Also is there anyone you might recommend for parts in case I need to rebuild the drive? everything is working up to the film drive post. (photo's attached)

That looks to be in need of a thorough service. The K-100G is from 1959, so the lubricants most likely are dry and sticky. The control cams no longer move correctly. Disassembly, cleaning, the whole procedure is indicated.

Thanks, I will do that to see if it corrects the issue.

Thanks to Simon for assistance/guidance. Pulled apart the take up reel arm and found the plastic gear had a tooth folded over stopping the action. I pulled the gear out, cleaned then heated the gear with my wife's hair dryer moved the gear back into position. Once cooled and reassembled it is working fine.

Bravo, that was worthwhile!
