Was on the interweb last week, and came across seed winnowers made by canary owners who had come up with a way of cleaning the chaff from seed. Youtube it for some vids. Anyway, went and bought a 12 volt computer fan, a 12 volt controller, a bit of clear polycarbonate and a length of pre-painted 65mm X 12mm pine moulding. Runs off a 12 volt sealed motorcycle battery, so i can take it out the back and not get in trouble blowing chaff all over Ms T's patio.

Thanks for that, I think I might have to get one made for me - I am not a make your own type of person, lol
I can give more detailed info if you need, Rowan. the bit of ply at the back is about 450 X300. the pre-painted board was about $5, the clear poloycarbonate was about $20, around $30 each for the fan and controller - so not cheap, but scrounging materials would make it much cheaper. A rather longer, "Director's Cut' vid here - Note never-before-seen dance sequence third of the way through...

I drew the design onto the backing board using a piece of the 65X12 as a guide, just eyeballed it really. Then used the drawing to take the lengths off, cut with a handsaw and a mitre box. handplane to chamfer the seedbox edges, cordless drill for the screw holes. I like that this is about A3 paper size, so easy to store in a corner somewhere. I definitely wanted something relatively compact. The tradeoff is it restricts the amount of material you can process per run.
Design mods I would make - perhaps use 90X12 or 90X18 board - this would give a wider device, with deeper and wider seed trays- upping the process volume, without compromising the compactness too much. The sloping board that the seeds get sorted on could probably be longer on the exit end, giving a bit more sorting room, while still allowing speed decrease at the top.
A 'normal' box style computer fan rather than the sexy looking one that caught my eye in the electronics store would definitely be cheaper, and with the extra width might give a better air flow - tho frankly I'm surprised at how even the air flow seems to be despite the fan outlet only being half the board width (I was going to make a super thin 40mm thick version, until I realised this would seriously limit the processing volume - but had already purchased the fan

wilscase: I'm a graduate student at Oregon State and have been working with populations segrgating for different color genes such as the B gene in Cucurbita. I'm curious if anyone has experience with crosses in Cucurbita maxima between grey blue types and orange?

wilscase: I have been backcrossing to the grey parent for 4 generations and have finally selfed the heterozygotes (for the Bmax gene) the populations have segregated for diffuse bicolor (pink/blue, orange green), blue green, blue, green, pink (salmon) and orange
Oct 18, 2022 21:36:29 GMT -5
wilscase: The genes involved are Bmax and bl. I have observed that Bmax is incompletely dominant to wild type (green). I have read that bl is incompletely recessive to Bl(wild type). I'm curious if anyone else has observed the behavior of Bmax in a grey/blue type
Oct 18, 2022 21:38:28 GMT -5
wilscase: It appears that bl and Bmax are interacting to produce different shades of salmon and pink.

wilscase: I'm also interested in any other color genetics, especially the relationships between B and L genes. In the right background these genes can dramatically increase Carotenoids (vitamin A)
