Chisel for mortise project - what size?
I want to install some sash pulleys in some old windows and will need to mortice out an area for each faceplate. (There is nothing there now, they are guillotine windows.) I am looking at buying one very good chisel for this one time project. What size chisel do I buy to do this?
The wood is very old and very hard. The dimensions are listed as follows:
Dimensions. Faceplate: 4 3/4" H x 1" W x 1/8" T. Wheel Diameter: 1 3/4". Housing: 2 1/2" H x 1 5/8" D x 3/4" W. Backset to center of wheel: 5/8".
Since the face place is 1 inch wide, do I get a one inch wide chisel? Or narrower? I found a butt chisel on the internet. What do you think? Would someone with small hands have more control with a shorter chisel like this?
I understand that I have to drill out the area for the housing. This question is about what's best for mortising around the opening for the housing.
