There aint no easy way.It's the hacking knife and hammer.Be careful not to let it dig into the timber and split it.There is an optimum angle that works best but you will need to practice to achieve it.

A bit of heat sometimes helps and for awkward stuff I use one of these Fein Multimaster but it wouldn't be cost effective unless you used it a lot. BTW they work just like a plaster saw in a hospital

Normal use for a router is for cutting wood, plastic etc, well you can also use it for cutting out old putty, and many other things.

Er but what happens if up a ladder they are quite heavy, plus I cant see how a router would get in the reveal of the window opener, I think its quite hard to do. (ex Glazier)

I find an old chisel and hammer works quite well,

...another vote for the above, but it helps if the chisel is sharp, then you have more control over it.

As well as the putty that is visable from the outside, you will also need to pay attention to the putty on the inner reveal of the unglazed opening.

This needs to be removed to ensure the new putty can be pushed in there and the new glass pressed against it evenly. A chisel used with the beval vertical (ie underside of the chisel facing you) along with a few light taps from a mallet, should help in this case.

It actually takes a lot of time to clean up a frame to reglase it. Also, if you have time, paint some quick drying primer onto the exposed reveals to further protect the wood.
