Converting camera to 24fps

[Stewart McLain]

I have a Minolta XLSound 42 that I'm interested in converting to a 24fps capable camera per these instructions:

 

http://super8wiki.com/index.php/Minolta:_how_to_modify_XL-42%2C_XL-64_to_add_24_fps

 

I'm curious if:

 

1) Anyone here has tried this and can give me any insight into the process.

 

2)  Does anyone know how a modification like this might affect exposure readings?  Will they be accurate at 24fps if I make this modification?

 

Thanks for your help!
