MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Alu frame back from powder coaters with some overspray into bb threads.
Will try Nitromors and gentle brushing, but if this does not work, then should it be a quick, easy and cheap job to do?
Or could I do it myself with a tap or is it a die?!?
It's a tap. Best to get your LBS to do it, although I have used an old steel cupped bottom bracket (shimano square taper) to do it once.
as above i used an old stainless steel bb to do one the other week and it was fine
Cut some slots in a steel BB cup, and your good to go. Nice and steady does it.
Really nickc? I'd have thought without a taper and a way of aligning the axes (plural of axis) there's be a real risk of cross threading.
Note - I am into my bodging!
1/4 section of an old steel cup & gentle working should do it.
I bought a Rock Lobster from Merlin once & had to send it back due to overspray on the b/b threads. It was bad though, totally un-masked during powdering.
