This is my link to what I did. The pictures should help as it shows what the insert looked like before I installed the knot........ https://theshaveden.com/forums/threads/tims-pewter-brush.58664/
Appreciate it much. Got the old knot out down to a depth of 15 mm. Will shoot for a 50mm loft with TGN Finest 22mm knot. Hole is 22.5 mm wide. Bill
Hey Jim - got the new knot into my Ralph Lauren pewter handle. It's TGN Finest (two band). Haven't lathered it yet but it should bloom nicely. Set it at about 50 mm per instructions fro Tony at TGN and also Rudy Vey. Many thanks for you advice. Bill
