Hi Dan,
Thanks for taking the time to reply, with the help of doober i found some bearings. Flanged ones seem far trickier to find. As you pointed out ebay.com was my saviour and i got some main bearings for under $4 each, i'd have like to have used simplybearings but the cost difference is huge and would end up being extremely costly. I've all parts printed now, i have a CR-10 3d printer so was able to do the blades in one piece. Hopefully the bearings don't take too long and i can assemble it to supplement my 100w of solar on my playhouse project which has 4.4Kwh of recycled lithium batteries. I'll pop up links to the ones i purchased to help people, also thanks for the amazon link, the machine screws should be such a simple thing but dang they tricky to find in decent pack sizes, have prime so shall get that ordered today.
