Seat Post Trouble

Your hot frame, cold seatpost will work but then you have to get it out.
That becomes tricky so I would try to avoid it. Have you tried greasing
the seatpost? Have you tried reaming the inside of the seatpost tube
with sandpaper on a stick or something? Is there a weld bulge inside the
seatpost tube or a burr? The seatpost itself is probably plated and you
wouldn't want to sand it down because the plating would come off. That
produces potential rust spots. Cleaning up the inside of the seatpost
tube is better if possible.

i tried to grease it up but it didn't help much. I havent looked for
burrs though- thats probably what it is.

I've had the same problem.
This is a manufacturing problem.
Sometimes the tolerances for seat posts are too low.

I told my reseller, and he sent me another one for free.
Throw away that thing, It'll only destroy your frame!

well on an attempt to try it again, it is stuck in my frame... badly
stuck. Ill send it back, but i need to get it out. of i use a metal pipe
a little smaller than the size of my seatpost ill hammer it through the
hole on the bottom of the seatpost tube (Near the wheel) i think that
will get it out.

I had this problem as well, i went to the bike shop. He stretched out
the top of the frame very very slightly near where the clamp goes.

If you have access to a metal lathe it's relatively straightforward to
cut a few thousandths off of the seatpost to make it fit.

WD-40 would be good to try and get in to help get it out, but for
getting it in in the first place, WD-40 isn't particularly good. It
isn't actually a grease or oil, it's a breakdown fluid used to dilude
and break down old oils and greases, thus freeing up parts. It will help
prevent corrosion okay, but grease or oil is better. There aren't really
any places on a unicycle that would benefit from a shot fo WD-40
compared to oil or grease. WD-40 stands for Water Displacement 40, if
that means anything to you.

Wouldn't that take away the chrome finish (assuming that the post had
been chromed) and leave it vulnerable to rust?

I had the same problem when i switched from the KH saddle and post to
the Miyata saddle and post on my Bedford frame, but not even close to
the extent that you clearly have. To solve the problem i just spun a
(cylindrical?) wire brush, by hand, inside the frame stem to clear out
some rust, burrs, and dirt. That did the trick pretty well. I still
need to torque the seat a little to move it up and down, but it's fine.
Good luck with getting you post out now that it's stuck.
