Reaming/cleaning seat tube

    Started trying to build up the Colnago steel frame bought recently. Installed the headset and was looking to put seatpost on but it was not not going in more than an inch (careful now…).

    27.2 standard seatpost

    Emailed the shop and they suggest reaming the tube. Obviously I would have expected this to be done before it left the factory, and I am not doing anything to structurally change the tubing, so am looking to see what homemade tool I can use to see if removing any excess paint or oxidisation from the internal tube will allow me to actually insert the seatpost.

    Anyone have any experience or suggestions?
