Removing Sprockets on a Bolex H16?

Recommended Posts

Hi gang!

 

So I am taking the crazy risk of filing one side of tooth from my Bolex H16 to be able to accept R1 film (one side perforation film). I did stuff like this before, not on a camera, I have some basic tool & dye filing knowledge, tools etc.

 

The question I have - ho on Earth do you take those sprockets out?

 

I took out the two screws that are keeping in on the axle but they are still not popping out. Both of them. I don't want to force anything, so I was wondering if they should come off together with the loop making mechanism also?

 

any tips more than welcome!!

 

thanks a lot!

Gabi

Dom Jaeger knows a lot about bolexes and often drops in to a thread like this and helps out. Hold off filing metal as long as you can.

 

Till then, is the whole sprocket assembly a stack, with the sprocket itself machined from a thin plate? If so, why not dissassemble that stack and replace the sprocket with a non sprocketed spacer.

Simply order a pair of one-side sprocket drums at Bolex International.

 

They should be mounted by a specialist because it takes a gauge for the correct height.

You could have your camera revised at the same time. Cleaning, lubricating, adjusting

 

From the fact that you have an H-16 with double-side sprocket drums we know that it

must be at least 60 years old. Time for a checkup
