I cut the struts to length and chamfered the short edges on the Morso. I then cut the trapezium shape by hand with a tenon saw and chamfered the long edges with a bench plane.
The backs are 3mm mdf. As I was planning on using brass hinges held in with screws, I needed to beef up the mdf. I glued a small piece of 6mm obeche (R&H F15) to the back of the mdf to give the screws something to hold on to. I also glued on each edge a length of SL4 to make the back nice and rigid. This also provided the necessary packing to bring the mdf up flush with the back of the frame.
I painted the struts and backs with Prussian Blue acrylic and Polyvine dead flat varnish. The hinges are attached with 10mm screws. As the hinges open up to 90 degrees I needed to attach some ribbon to act as a ‘stop’. I used 10mm grosgrain navy ribbon and folded over the ends and glued with Evacon-R to make sure the ribbon wouldn’t fray and would be strong enough when screwed in place. The backs are held in place with black turn-buttons.
As with a lot of new projects , it is the problem solving that can take up your time. Once I started this job it didn’t take too long to complete and I will certainly make these strut backs again. I only make hand finished frames and it seems right that the strut backs should also be hand finished.
I’ll see what my customer thinks of them tomorrow
