Only on a bike forum can you post something with the title "need to ream out my seat tube" and expect serious replies.

Good luck with the repair.

I'm not sure what size the packaging on mine was but it measures near 1.25 inches and it was perfect for a 27.2 seat tube. they compress a little. I used it to clean out the oxidation in the seat tube. before honing I stuffed a rag down the tube so that I could bring out the debris when I pulled the rag out. I used one of those claw thingies to fetch the rag.

Not too sure if this will help OP's issue, but maybe it will help another with similar problem.
I recently had to clean a series of burrs out of the lower portion of the ST on a new aluminum prototype frame which was scratching the crap out of my Thomson
I asked FTW/"The Man" (http://www.frankthewelder.com/) what I size/tool is best for the job, and this is the info he gave me, "J, if the seat post size 27.2 it's a 1-1/16" ballhone. The ball hones don't change the shape of the hole, only polish it. A cylinder hone makes bores round and flat walled. You can rent one of those from a good auto parts store for $10.00. Don't bother buying one of these unless seat tube is really amess and you are into spending big money. The cheap ones are useless.
For Ball hones, McMaster (http://www.mcmaster.com/#=d98rnx) is what I use. I would get 1-1/8 and 1-1/4". I use them on frames after reaming and they are awesome.
