Ammonia didn't work on my frame, I'd try the other. Caustic Soda

I had a very stuck seat post to extract out of my Saracen. I tried all the usual methods to no avail so finally dug out my welder to weld a length of steel flat to the saddle subframe.. At the time I wanted to save the seat post too. With the leverage provided by the steel flat I was able to smash the bond between the 17 year old post and frame.. See below..

OK!
I have found a chap that has a pilar drill in his workshop. I have bought a couple of large drill bits and aim to clamp the bike into the pillar drill and simply drill out the alloy seatpost.
Has anybody tried this? In theory it should be an easy job as the alloy is so soft. I would imagine the drill bit will eat through it.
Fingers crossed!

I've tried it on the infamous Brodie frame, handheld drill with a drill cup on a long extension. It works, slowly. It very noisy too. (I have to get ear protection before giving the last blow to my frame, and get a new cup, the first is gone).
Just stop every now and then to let the metal cool down and prevent the seat tube from warping... not that I should talk about being careful...
Good luck!
