Here is an o.g. seat post that my friend Bill sent me to copy.
I had to file a bur off of the large diameter to get the large nut piece to slip off. This is also the seam where the .5 threaded part presses into the upper piece. I can not tell if Sears sweat brazed the two pieces together because of nickle plating,
I decided to make the seat post for my cannonball bike one piece, which meant a lot of turning lol.
Here is the piece almost done, I still have to cut a groove in it and drill a hole for the top bolt, but you get the idea. The other ones that I plan on making will be two pieces just like the originals.
Nice work on the seat post. Did you see that Excelsior one that sold on ebay about two weeks ago for something like ~$250? all worn out too. crazy. Mine's in decent shape, I just had to make up a new bronze bushing for it.
