Am I happy I took the wife out to the pub for a meal tonight to make up for neglecting her over this week ? Well yep, too right. Bumped into Jim the bike who sorted me out with getting the tapered roller bearing seats out of the headstock. Jim nipped across the road to his house and came back with a right nifty wee tool for getting them out. Back from pub, in the shed and 10 mins later both seats were out . Frame ready to take to Triple S in Bingley for powder coating now ... small step for mankind, great leap for me ... no need to piss about with dremels and cutting discs. Procedure documented below:
Photo 1: Bearing seat in top of headstock
Photo 2: Nifty wee bearing seat removal tool
Photo 3: Tool in place on top of headstock
Photo 4: Drift inserted from bottom of headstock
Photo 5: Couple of whacks on the drift with a rubber mallet and the bearing seat is out
Repeated all this at the other end to get the bottom seat out ... bit more triky as this seat's diameter was about the same as the headstock inner diameter and was flush into the shoulder, so next to nothing for the tool to grab onto. Expanded the tool as much as possible and the first couple of thumps on the drift moved it enough through friction to get a gap between the seat and the shoulder it sits in for the tool to get a better grab on it. Easy peasy when you know a man who knows how and has a tool to hand. Well chuffed I am.
