The first of my box sliding sash windows has now been installed for 10 months. It's still looking good and functioning well. The seals are keeping it draught proofed, there are no signs of any joint movement or wear and the double glazed units are performing as they should.
The only slight problem has been a sash cord stretching so one of the weight touches the bottom of box. I just need to move the knot up a bit.
Details and Construction of DG Timber Box Sliding Sash Window plans to Download?
It's now on my list to build the rest. Before I do, I will review the construction details and amend the plans if I can think of any better ways to do things. I'll write up and draw all the construction details, including measurements and installation. I'll also detail the manufacturing using basic workshop tools.
I plan to make all the details available as an ebook, available for a small charge. If you are interested please leave a comment to give me the motivation to crack on.
The sums seem to add up if you have the knowledge, skills and time. A bespoke bought window would cost around £1000 each and a home made window around £300. I've justified equipping my workshop/garage with part of the savings I'll be making. If I could have bought the plans a year ago I would have.
Let me know what you think.
