redline flight help please

[crusty]

i have flights with sealed bottom bracket the spindle seems a bit loose in the hole is this normal or should it be a tight fit i would imaging the later but would like advise asap as i'm trying to build bike today
thanks to anyone that can help

[harris]

yes they should be a shoulder fit nice and tight not over tight thou.if they are loose they will damage the bearing .

[Bren Gunn]

The bearing you are using needs a very fine top hat shim to make the internal size smaller. I think the spindle is 19mm and the bearing 3/4" ... could be the otherway around

you might have 20mm bearings
