Dunk,
I was just enquiring about how far the extension had gone in so I could propose a solution that we use in the shop... which you sort of
allude to in your last post.
If there is not too much extension up the mast and you can get a long metal pole down the from the top of the bottom section of the
mast then you can have a go at the following.....
Saw the end of the extension off where it comes out of the bottom of the mast. Then with just a 'new' hacksaw blade cut slots up the
length of the extension and be careful that you only just break through the extension. Continue this procedure around the extension
until you have got slots all the way around (or you are too pissed off to do anymore.... which ever is sooner ;-) ). This weakens the
extension and makes it easier to shift. Then with the long metal pole down the mast hammer the pole or turn the mast upside down and
ram the mast over the pole while the pole is on the floor. Be careful that the extension doesn't launch it's self like a rocket
though.....
I have used this method on only a few of the most stubborn extensions and have had 100% success rate. It does however take a while to
do so be patient, after all a new extension is cheaper than a new mast....
Hope this helps,
Hans.

Hans
Have bitten the bullet and tried your method (bearing mind I was using it as a not ideal mast for my 4.7). I sawed the end of the mast
extension (but left enough extending with one hole for purchase) and have got a handy little handle that will hold a hacksaw blade from
Homebase. Found that it's quite difficult to keep a straight cut without bending the blade and to keep an even depth in the cut.
I'm thinking along the lines of some sort of lever to force the extension out by locking against the old Radz collar (to protect the
mast) and locating the other end through the remaining extension hole. Have tried to use a car jack but couldnt get enough rigidity in
all the connecting joints.
Anybody got any ideas?

stuck mast extension
Just read the posts about stuck mast extensions cos I just got one. Best plan for me was to heat the metal extension (flame of any
description) to just bearably hand hot, then with a sturdy bar in the extension holes tug the mast horizentally, with a pillar or wall
corner restraining the bar. You can get a lot more force this way rather than using rotational, and you are moving in the right
direction rather than just round and round. The heat helps agreat deal too.

Much better than hammering on something poked down the mast is to drop a heavy metal bar (several kg) into the mast. The with the mast
held vertical shake it up and down such that you bounce the metal bar against the extension.
This is far far more effective than trying to transfer a hammer blow via a rod/tube.
Soap sounds like a good idea too.
Good luck
Dave
