I fully agree with Will. The journey is sometimes much more enjoyable than the destination. Keep on fixing them Andrew and I'll be watching from this side of the pond. :D :D Cheers :beer: Don PS: Looks like DavidA beat me to the explanation. I guess that makes it unanamus.. |

Today I finally made a start on making a replacement take up spool. The original spool is in a sorry state. The two sides screw together to allow taking the used wire off easily. The threads have stripped, and some previous owner has wrapped the male side with PTFE tape to allow it to grip. Also the side cheek on one side has cracked and been rather crudely glued - time for a replacement. |

I decided to use polycarbonate, as it machines well and is pretty tough and resilient. The original spool cheeks are moulded, with a tapered lead in to guide the wire provided by a perspex disk insert. To replicate this I chose 6 mm polycarbonate sheet which I can taper on the lathe having cut the basic shape on the CNC mill. The hub diameter is a nominal 60 mm and I found a suitable rod of 70 mm on eBay for an acceptable price |
