Venetian sash are those where the frames are divided by mullions into three or more openings, in this case the centre pair of sashes is hung, the smaller side ones are fixed, the solid mullions are there to divide them, the cords for hanging the centre pair of sashes are taken through the top of the mullions over pulleys into the side boxings.
Start with the sill with sloping shape and joints for the box-linings and mullions.
The top and the sill, with the joints for the mullions
Inside of a mullion lining grooved to fit onto the mullion
Top of mullion
Top part of pulley grind off, so that the wheel can be brought close up to the head of the frame.
In the mean-while I started on the wood for the windows.
This is a plate that will cover up the cord that will run over the top of the fixed sashes.
Cord run behind the plate.
Frame parts ready to assemble.
Frame glued, screwed, filled and sanded.
Fit the windows.
Waiting for glass, all glass beads cut, pre-drilled and everything undercoated.
Now that the double glazing is in place I can cut the lead weights, hang the windows and make them slide.
Sash is running nicely, all prepared and ready.
