Powder coat problem :(

(1/4) > >>

Gizmo:
Hi just got a frame back from powder coating , but the bottom bracket cups won't fit
as they powdered inside the bb  :(
Had a 4lb sledge hammer on it ( with a block of wood either side lol ) & nothing
 
Any ideas ? Part from dont take it there again  :LolLolLolLol: ta

pickle:
I guess you could file off the powder from inside but it may chip bits off the BB  ???

You didn't send it to Dan then

gavking:
Get a stanley blade and cut the powder coating away around  the inner  edge of the bottom bracket tubing and then scrap the powder off with said blade insinde the bottom
bracket till the coating is off!! this should stop you chipping the stuff on the parts of the frame you can see!!

I had the same touble. I was told to stick the bearing cups in the freezer for a couple of hours, then take em out and you can push them in easy with just your hands. Worked a treat as no need for hammer or any tools :daumenhoch:
