My next job is to make a imitation sliding sash window with curved top, this has to look the same as the existing window in the house. Instead of both sashes sliding up and down the top sash will be fixed and the bottom sash opening inwards.
Fist job is to glue and cramp 3 pieces of 4" x 2" timber together to make the right size timber for the head and the top rail of the sash.
After the glue has dried its time to mark out for the curve, then cut with a jigsaw.
The marked out timber ready for cutting.
After the timber is cut I am left with a curve rail 3" x 2". I only need 1 timber this size for the top rail of the sash but for the head I need to glue 3 timbers together to make a head 6" x 2".
Next job is to make the sashes,
The two sashes are made and now its time to make the frame.
The frame is made and now time to cut the head to fit.
The finished frame ready for a coat of primer. Time to fit the beads now.
I have put slots into the top parting bead to enable me to bend it to suit the frame.
I did the same to the outer staff bead then filled it. Now its ready for a coat of primer and fitting.
