Here's a pic of the winder with a 30x54mm bobbin, bit of play on the shaft though due to not having any bearings, secure enough for medium sized jobs. Not enough meat on the frame to drill out and fit bearings.

The plastic gears are only used for the 8x mode, for 1x everything is metal.

The plastic handle was rough/sharp round the edges, I had to smooth it with 400 grit wet/dry sandpaper.

The handle tends to bump into the other shaft and needs to be set carefully. When in 1x mode I had to file a flat edge on the shaft to secure the handle better.

The shaft has a 10mm metric thread, has a centred hole at the end so could be secured there.
