20" Seat Post

Greetings!

Hope all you Uni Dads had a great Father's Day.  I got a 24" Semcycle Deluxe
for my Father's Day present!  :)  ( I share that with the group because
everyone I work with could care less!)  Unfortunatlly I won't be able to
enjoy it for about a month while the torn ligaments in my knee heal.  :(

But, that's not why I'm writing.  I have another dilemma.

I had to weld the stock on my homemade 6' giraffe for the second time.  The
pole that the seat post fits into broke the weld both times.  This happened
 because while I was learning to ride, I would fall off and the seat would
hit the ground, bending the metal.  I would then try and straighten it out.
 The stress from doing this a few times breaks it right where the top piece
of stock goes into the crank assembly.

Has anyone experienced this before?  The second time we welded it, we really
drew a heavy bead on it, so I don't think it was a case of poor workmanship.

I'm thinking of making the pole really short and getting a really long seat
post so that if anything bends, it will be the post, which is easier to bend
back, and replace.  Where can I find a 20" seat post?

Thanks!

This is always the weakest (most stressed) point on a giraffe frame. A
shorter post above will not make any difference. You might have to replace
the crank barrel (lots of welding) but don't take chances with that weld.
If it goes while you're riding, it can really hurt.

Contragulations on your Father's Day present!
