Another snow day and working in the shop. Seat post seems to be a bit tight when a 27.0 is inserted, so I get out the junkyard tools for the repair. SLX tubing should be 27.2 and when I get the 27.0 past the first inch it is sloppy so I figure i might have compressed the binder area with the re-weld of the stay. A heavier grade of reaming paper and a few minutes of work and the 27.2 post goes in to within an inch of the post head. Pics of the junkyard tool:

The tool is a spool of wood mounted on an all thread rod, and used with a drill for creating a circular motion of the grit paper.

The paper is mounted with a piece of masking tape and the length of the paper determines the thickness of the reaming diameter.
