[Closed] Just had my frame powder coated and............

Yep, but you'll have to find a shop with a seat tube reaming tool in the right size, which may not be all that easy.

Should be able to get the worst of it out carefully with a knife or a file, I'd have thought....

left over grit blasting media, scratched all my seatpost up, give it really good clean out..

emery clothes glued to a tube.
And some jet washing before putting the BB in.

old sacrificial seatpost as a reamer 🙂

or an undersized one with a bit of sand paper on it

the frame is a 853 steel, 27.2mm, but like it ieda of a smaller post with sandpaper on!

Dremel?

Careful application of a bit of paint stripper, powder generally comes off a treat.

I think sandpaper on a broom shank should sort it.

Cheers all!

I used a long straight allen key that came with bombers, duck-taped a bit of kitchen sponge and some fine sandpaper (that green stuff?) in a spiral (if that makes sense? so they're both taped to the metal shaft) then put the other end in a drill.

Then took it off again and reversed it to match the direction of the drill.

Worked pretty well (after I got the amount of sponge right to get the right pressure on the paper). I couldn't and can't think of anything better for the job. I'm not an engineer though!

is it just me who would get the powder coaters to sort/pay for sorting it?

or is that not the done thing in such situations?

Then took it off again and reversed it to match the direction of the drill.

no just reverse the direction of the drill? most have just such a feature nowadays.

depends who did it and how much you paid.
35 quid from a generic powder coater i'd do it myself.
100 quid from argos or similar and you might start asking questions.

this one didn't! my grandpa's old drill.

Paint stripper (carefully). You want it back to the bare metal without taking any metal away.

Depends on the amount of paint too, are we talking a bit of overspray, or have they totally coated the inside of your seat tube all the way down?
