I am building up Merckx Corsa Extra this week, and there seem to be small pieces of what I can only imagine is rust rolling around inside both the fork and seatstay. I thought about vacuuming them out, but there are no vent holes to be found.
Is there anything I can do about this, or should I just build up the frame and forget about it?

Doubftful that a sealed tube has flaking rust large enough to be heard. Most likely left overs from the welding process.
A picture would make this thread way more interesting!

You sure it's rust? I'd guess brazing material.

probably not rust...probably flux.
if there aint any holes, nothing you can do about it either way, just build and ride the thing ;)

you could add vent holes so you can clear out the torching detritus.

If you have access via vent holes, spray the interior with Frame Saver. If fortunate it will trap the bits, not allowing them to rattle.

Or drop some paint inside, that will trap the suckers big time.

Thanks for weighing in! With no vent holes, I guess there is nothing I can do but build up the frame and ride. I'll have photographs soon.

Sometimes the holes are not at the bottom but at the top of the seat stays, check that out.
THe fork it is interesting because there's only one guy I know that brazed w/o making holes. And he did not work for EM and besides that he died a few years ago so...
Always you can torch that a little bit, hope the bike needs a new paint job.

I don't think there will be any torching this time!

U are going to send your riding partners to a mental institution :)
Remember a guy from my team back years ago, everybody he was there in the back due to the clic clic thing he had going one just like you inside of the frame :D It was annoying but was driving other teams riders crazy.
