Hacksaw blade appears to be doing the trick. This is the product of 3hrs of constant sawing. Haven’t made it the full way through lower down but reckon a hour or so tomorrow and should be there. Once the two slots are fully cut I’m hoping I should be able to get the rear half loose by hammering something like a screwdriver in behind.
I would be very careful about hammering a screwdriver down the back. it's a good way of either splitting the seat tube, or getting the screwdriver stuck as well...
