Tapping Dropout Eylets.
Hello to All,
I thought I posted this earlier. But I can't find it. so here is the short version.
I need to clean up the threads on the droupout eyelets of a new-to-me olde bike. Could have been paint, or poorly threaded eyelets from the frame maker. But on this new/olde frame, the bolt will not pass alltheway through like it should.The thread information on the bolts I got that fit the eyelets is:
"5mm x .8-20"
Another bolt that fits is from a rack mount kit. I think it is a Blackburn.
The tap I got from the hardware store would not pass without too much force. I tried it on a throwaway frame to test. The bolt I have did pass, mostly. I looked at some online bike tool and general tool sites, and I could not find an exact match. I know they are out there; we usta use them to clean up rack mount eyelets in the shop. It should be out there somewhere. I know that others have a need for this. It should cost like less than about $14USD, shouldn't it?
Can anyone point me to this tool? Thanks.
