stuck seat post

[Voyager Al]

On my Monark Silver King, the seat stem is sorta like a quill steering stem,and the bolt was missing when I got this bike. And the stem was tight. I tool a long phillips screw driver and pounded the wedge down, and the stem now rotates, AND I got it to raise 3/8 of an inch. And it is tight, and not coming up anymore. I had a pipe wrench on it, and beat it up to where it is now, but the stem is mutilated. If and when I get it out, I will put in an altered steer stem. The big problem is I dont have a big bench and vise to hold the stem while I twist and pull on the frame, and cant find my 5 pound slide hammer I once had. Anyone got any ideas? Besides taking it to a machine shop? I cant take stuff in and out at my work, where we DO have the equipment to do it.Its worse than airport security. Its a NO METAL inspection, as we do precious metals. Anyone around me with a heavy vise/table combo? DogDart? HELP!!!

The best way I have found is to strip the frame down to make it easier to handle, stand on the chain stays and attach a clamp style seat to the post then twist and pull. Little WD-40 helps too.

its stripped, and I have a 1/4" hole in the post that I put a hardened rod thru to pull and twist. No good. PB Blaster has been sprayed in it for a week...

Might try to rinse it out and put a little oxalic acid down in it to eat away the rust and corrosion then try again.

I had a wedge nut stuck in a steer tube that no amount of beating could remove , I ended up fashioning a spacer big washer combo and used a bolt to draw it up , similar to using a steering wheel/ harmonic balancer tool .

aluminum frame, so oxalic acid is a no-no.
Im really hesitant in using a puller that bottoms out on the 80 year old aluminum.Im hoping to either use a large dent-puller slide hammer, or mount the stem in a vise and twist and pull on the frame. The stem is LOOSE totwist.

Oh alloy frame, Errrr. I guess just keep oil soaking and pray, curse, beat on it, twist it, and oil it some more.

I had one stuck and after days of PB blaster and WD40, I got it to come out by using a pipe wrench to turn and pull upwards. It was a real bear...but persistance won.

Got permission from the security officer to bring the bike in the shop. We cut the stem flush with the frame,then used a scroll blade in a saw-zall, and split the stem,twice. Pushed it down in the tube, pulled out the outer sleeve, turned the bike over and the stem fell out. 1/2 hour,tops. My boss is a git'er done kinda guy. Security x-rayed the frame on the way out,to make sure I wasnt smuggling out the good stuff..... Now I gotta alter a steer stem to work as a seat stem.....
