[AT] OT: Rosebuds! The oxi-acetylene kind...

Dave if the part is such that you can do it without messing something else 
up
you might find you have better success, and cheaper, by just building a big
fire and throwing the part in the bed of coals for a while.

Subject: [AT] OT: Rosebuds! The oxi-acetylene kind...

I'm pretty ok with cutting & brazing, but have never used a rosebud to heat 
something, and my experience today has me scratching my head.
The project at hand is freeing up a cast iron wheel hub, stuck on a keyed 1" 
shaft. This is on an old Gilson / MW garden tractor transmission.... the 
idea is to liberate a set of 4 of these hubs to make dual adapters for use 
on another tractor with a FEL.

I have soaked it for quite some time and have a puller tensioned on it, but 
it's not moving... so now it's time for a little heat.

I bought a new victor 8-MFA rosebud and lit it off as I would the torch, but 
when I try to get a blue flame, it flames out with a pop!

What's going on here? Do I not want a hot blue flame, or do I simply need to 
feed a lot more of both gases to the torch? Or??  Any insight into these 
things would be appreciated!

   btw, I'm on digest, so it'll take a day for me to respond (:<((
