The story of how I grow and spin my own cotton is still continuing<\/a>, this years crop looks like it will be a big one (relatively \u2013 how much can you expect from three or four plants?). I still spin the cotton direct from the boll and have not gotten around to building a cotton gin based on Ely Whitney\u2019s model, but I have found that spinning from the boll still inevitably leaves some cotton adhering to the seeds. I don\u2019t want to waste any of my home grown organic cotton, so I just stored them away to await further processing.<\/p>\n

On one of my expeditions on the net, I cam across a photo of a cheap and easily constructed cotton gin of a novel design \u2013 there was only this one photo from one angle, with very little detail, so I had to work out the construction details myself. The gin is based on a wire mesh tacked to a frame with a backing board, then a \u201cflicker\u201d is used to draw the cotton though the mesh, leaving the seeds on the other side.<\/p>\n

One bit of detail in the source was that the wire mesh was \u00bc\u201d squares (about 6mm). I found this a bit of fun to get hold of. The local Bunnings had a roll a metre wide by about 30 metres long for well over $100, this was a tad more than I intended to spend so after I got up off the floor I continued searching. A hardware local to where I work had some gutter mesh which was 190mm wide and a few metres long \u2013 enough to make 20 of the things \u2013 anyway an investment of $11.00 or so didn\u2019t seem to much to pay.<\/p>\n

To make the top frame I used 19mm x 42mm DAR maple ( a bit more expensive than pine but less prone to twist), the width of the wire mesh set the limit of the width of the gin to 237mm (to the outside edge of frame) and for no good reason I set the length at 380mm. Having cut the timber to length I then used by small band saw (you could use a hand\u00a0 tenon saw just a s well) to cut a half lap joint at each corner. The corners were secured by two 15mm wood screws, holes pre drilled and countersunk. I then just put a tack in each corner and one in the middle of the long side to secure the mesh to the frame, this size frame allowed for 2-3 meshes overlap for securing the mesh. Note \u2013 make sure the long wires on the mesh face the top, so you can pull the flicker along the long axis of the gin.<\/p>\n

To make the base I placed the top frame over some 9mm thick 5 ply, drew around it and then cut it out with a hand saw. After a bit of a trial I found that there needed to be some clearance between the mesh and the back so I screwed some 10mm (anywhere between 6 & 10mm would probably be OK) off cuts the same width as the top frame to the back board, applied two hinges and viola! A cotton gin!<\/p>\n

I had to buy a flicker from Viginia Farm Wool works which cost me less than $12, to pull the cotton through. If you made the gin wider you might be able to use a wool card if you already had one, but that pre supposes you could get wider mesh.<\/p>\n

And the damn thing actually works! You pull the flicker first one way then the other across the top of the gin and, hey presto! The fibres are pulled through, getting caught by the wires of the flicker and the seeds (most of \u2018em anyway) stay on the other side.<\/p>\n

If you had 400,000 acres of cotton to process, this would get awfully tedious but for small amounts of home grown cotton, or to use it as I do to reclaim otherwise waste cotton, it is well worth the effort to make.<\/p>\n","protected":false},"excerpt":{"rendered":"
