Or put it squarely in a vise and cut right at the edge of the vice (so
the hacksaw teeth are scraping paint off the vice).

Cutting a Thomson post

What is the best way to cut a Thomson post down to size?

I’m thinking of using either a pipe cutter or a hacksaw. The pipe cutter has given me better results on other seatposts, but the Thomson has a weird ovalized inside diameter that might cause problems for the pipe cutter. A hacksaw would work, but I can never get a straight clean cut with a hand hacksaw. I don’t have a powered hacksaw or bandsaw handy.

John,

Thomson gives an answer in their FAQ’s…

Wrap some shim stock(roof flashing) or a leather belt around it to mark it;
cut along dotted line.

Try the pipe cutter first and have a hacksaw handy. Cut near the bottom of the post so that if you do mess up it that piece will be cut off anyway. Finish with the hacksaw if nescessary.

John-

I’m going to go machine hub parts tomorrow. Call me or e-mail me if you want to use a bandsaw to do your cutoff. I think I’ll go in before noon.

all of these are good ideas

the one thing i would suggest is which ever way you chose to cut it,cut below your target area as a test ,of your chosen methed:)

I’ve cut down a couple of Thomsons and a couple of others by using this
simple method. Put seatpost down on edge of bench. Step on it with one foot.
Hold with one hand while cutting with hacksaw in the other. Works perfectly.
You just file down the edges slightly when done to make them smooth.
