How To Gin on your Roller Cotton Gin

This is the thrid video in a multi-part series on making your own simple Hand-cranked Double Roller Cotton Gin. I haven't seen the first two videos, go watch those or this won't make much sense:    • How To Build a Roller Cotton Gin For $20      • Add Gears to your $20 Roller Cotton Gin   This video simply demonstrates how a double roller cotton gin works and that it will indeed gin Sea Island and other long-staple (blackseed) cottons. In it I take the double roller gin you saw me build in video 1, and then modify in video 2, and gin a few seed of Sea Island Cotton I grew this year. This video also demonstrates how it won’t gin Upland (short-staple/greenseed) cottons. A double roller gin functions by grabbing and pulling the lint between the rollers with friction and rotation, peeling the lint off the surface of the seed coat. Blackseed cottons, like Sea Island Cotton, can be easily ginned in this manner with a simple Churka-style gin like this. The lint of Upland Cotton clings too firmly to the small, soft seed in its center and more often than not be crushed and pulled between the rollers on this style of gin. Historically, Upland Cotton was ginned with a saw gin (the machine Eli Whitney invented) which hooks and combs the lint off the seed. Long-staple cotton can be ginned on a saw gin without issue but the forces involved are often overkill and will tear the longer staple, reducing the fiber length and thus defeating the purpose of growing the more labor intensive Long-staple Cottons.
