My bikes almost finished. Pics here

[02gf74]

Quite marvellous. A frame from when peeps could be bothered to fill and smooth fillet welds...

It's carbon ;-)

I stand corrected - looking the pics on a big screen there would have to have been a lot of filler on those joints

Re: Re:

If seatpost is aluminium then a pipe cutter will do a neater job without leaving burrs on the outside. If using hacksaw, fit jubilee clip to act as a guide., then use file to put small chamfer on outside edge, avoids scratching the seat tube which then avoids scratching the post.

A pipe cutter might not work on a Thomson post. Reason being that rather than using a standard gauge pipe pressed or welded onto the head they started with a billet of aluminum and machined the shaft and lower head out of it, and then machined the inside of the shaft oval to save weight but have strength in the direction it's needed. It's probably overkill for a seatpost but you have to admire the attention to detail.

Here's one I cut earlier (with a hacksaw) to show the inner profile -

I would be very surprised if it wasn't an extrusion.

I stand corrected, the inner profile is extruded, the rest is machined - https://www.bikethomson.com/product/elite-seatpost/
