Thanks for the compliment on the blog Colin. I'm making slow progress but progress all the same. I'm on to the box frame now and will be ordering the Glass, hardware and lots of lead soon.
Also looking into Linseed oil (Holkam) paints, I need to check compatability with dry glazing seals.
I am thinking of making the plans available when I've got the the first window completed and fitted and working. But I can't promise anything soon.
