Tool for rebating a window frame.

Nobbie1967

Most of the house is double glazed, but there are two original single glazed wooden windows at the back that are solid, but single glazed. Rather than replace at £££, I’m looking at fitting double glazed units into the frame.

Currently the single glazing is held in by glazing bars, but the recess the glass sits in is too shallow for the double glazed units to fit. I need to deepen the rebate and would usually use my router, but as the frames are inset into the brickwork, the router will foul on the brick. Any ideas for the best tools to achieve a neat rebate to accommodate the glazing units?

can you post a photo? Is it possible to get a multi tool into the gap to create the rebate?

a router with the correct bit inserted - palm routers can be had quite cheaply. otherwise a hammer and sharp chisel!

I think I’ll have to use the multitool with a good sharp blade and concentrate to get a straight cut, unless there’s a tool like a router without the overhang which will foul on the rest of the frame.

Actually, having just looked at my own photos, once I remove the glass I can route perpendicular to the frame and just use the multitool for the corners👍
