Shop Window II

Here are some progress shots in the long process of making a simple window.  I have a much greater respect for the tenacity of our ancestors.  After having  joined and glued [with liquid fish glue] the sliding window sections together, I used some small square birch dowels to peg the saddle/bridle joint at the corners, they are put into holes made with an awl.  This does not remove any wood and when the moisture from the glue is introduced they swell back around the square peg, making for a most secure joint. 

I wiped the completed frames down with a mixture of alum and water to make the fish glue waterproof and to raise the grain.  I allowed it to dry then sanded down the raised grain.  A coat of Moses T’s St. Johns Oil and allowed to dry for 24 hours.

I then cut a couple pieces of glass in preparation for glazing the windows.  I laid down a bead of oil based glazing putty in the rebate and pressed in the glass until it made a tight but thin seal between the wood and the glass.


I then cut some triangular glazing points from some sheet zinc.  Zinc is preferred for this application and I happen to have a sheet of the stuff, which I also used for the dividers between the windows.  Easy to cut with tin snips.  Using a flat ended putty knife, I gently pushed down on the glass then pushed in on the points.

Then another coat of glazing putty finishes the sash and it is ready to install.

Unfortunately, I deleted a couple of photographs of the process of using a stringing cutter with a single serrated blade to cut the thin slot around the inside of the window jamb that accepts the 1/2 inch wide piece of zinc.  It was set in half way, 1/4 inch.  This piece separates the two windows and because it is zinc it will weather well.

The view from outside.  I still have to remove the tape residue and the door could use a coat of paint.

I will probably add some trim pieces, a small wooden awning to shed the rain.  I will also have to make a screen for the window when the weather warms up.

It was well worth the effort as I now have light and passive ventilation in my new shop.
