In the BfB extruder tutorial video (which now works wonderfully) it is suggested to wrap solder around the thread of the main bolt under the bearing. What kind of solder is best for this, and what dimensions. Also does anyone know of a good UK source for it?

well.. since I guess it's metric thread M8 (x1.25) I think any 0.5mm solder will do (one turn is 1.25mm wide, half mountain half valley... you need to fill the valley.. that's 0.625mm but the solder is round not triangular and who cares anyway... so 0.5mm solder)

Sources.. well ummm

I used 0.7mm solder as you want it to be proud of the thread before solder i used PVC insulated wire (normal wire) all you are trying to achive is that the bearing is central on the bolt when you tighten the nuts so absolute size is not critical just that it is a tight fit as the bearing is push/ bolted over your choosen material. Hope this helps.
