Works every time. I found it only needs about 2 minutes to soften the loctite enough to get it off, using something to get more leverage on the allen key. Chances are that no matter how careful you are, you'll still wreck the old aluminium hammer, but you won't be needing it again, will you?Originally posted by elrikos
i found the best way is to remove the hammer assembly from the marker and stand it, hammer side down, in a pan of boiling water for 10 minutes or so. softens the loctite really nicely. then get a bit of corugated cardboard, wrap it round the hammer and use some mole grips on it. that cardboard is surprisingyl grippy and means the mole grips won't scratch the hammer.
thats how i did it
