Development of the Catican Cotton Gin Mark II continues. If you're new to the topic, I grew cotton this year. I harvested it, but it's full of seeds, hence the need for a cotton gin. A gin is simple - two counter-rotating rollers, pressed together that pulls the lint through as it squeezes out the seeds. I made an initial cotton gin, but it was horrible. On to the second version!
Disappointed with my second attempt to make wooden gears, I spent some time clicking around YouTube. Jackpot. I came across a brilliant idea - take an automotive timing belt and glue it to the rollers. Dig the photos below.
Ready-made, well-fitting, compressible teeth that you can apply to the rods.
Now all I need to do is get the ends of the rods lathed so the timing belt rests at the same level as the wood of the rollers.
