Thank you for the comments
I am sure some one will make him self known soon .
The large pulley involved some outside square thinking .
I started with 3 mm thick plate brass as per the original inserted. Hub and turn true .
Now the rim is wider so i got some 7 mm round brass rod . Milled a 3 mm slot the length of it .
Rolled the rod around the disc the silver soldered in place then turned to shape .
Cheers
