Alpha Herring spinning wheel bobbin

thingiverse

This is a bobbin specifically designed to fit only the Alpha Herring spinning wheel. As it screws onto the spinning wheel, I used a metal insert with thread because I was unsure about the durability of plastic on metal. I ordered the insert from Amazon for its ease of delivery, but the same item can be found elsewhere. Below is the UK site, and by checking the details, you should be able to find somewhere that sells something similar. https://www.amazon.co.uk/gp/product/B07GZRMRS5/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 I used an epoxy resin to secure the insert in place. I believe superglue could also work, but I haven't tried it (I'm a big fan of epoxy). The UK Amazon link for the one I use is below, and again, I'm fairly certain you can get it elsewhere. https://www.amazon.co.uk/JB-Weld-Original-Cold-Formula/dp/B0044US7SY/ref=sr_1_9?crid=3BE01L317CQYM&keywords=jb+weld&qid=1574595854&s=diy&sprefix=JB+%2Cdiy%2C145&sr=1-9 You will need to print one core and two ends. I have designed them as separate pieces because my printer has a small print area, and also because I like to be able to break down my bobbins for storage. The ends are identical, and they screw onto the core.
