Hi, We've got some original 4 panel doors in our Edwardian house.

In order to get a little more light into our kitchen I'd like to remove
the top two wooden panels from a door which leads from our kitchen to
our utility area.

I'm not quite sure how to remove the wooden panels as they were fitted
when the door was made and are held in place by the thicker boards
which make up the remainder of the door.These boards taper inwards to
the panels and it is this tapered bit I need to saw to fit the glass
and keep in place with putty or some other bits of wood.

I'm assuming I'll have to use a circular saw though I don't actually
own one and have never used one. Is this going to be easy to saw or
should I be using some other tool.

As I will also have to purchase 2 panes of toughened glass (along with
the circular saw (£20-£40 ish ?)) it's not going to be a cheap task
and I did consider buying a door with glass fitted from wickes/homebase
etc which cost £50ish. However as my door is at least 3 inches shorter
and narrower than the standard size I don't think that's feasible.

Any advice?
