Update with photos
The final design i think. Same as last one but with two 2" supports as seen instead of one 4" will give more even support.
Unpacking 50 metres of 4 oz polyester wadding (40" wide). I got a bit of a shock when i snipped off the plastic straps and took it out. The pictures do not show just how big it was uncovered. It nearly filled half the width of the room and was even bigger when stood up length ways. I had to do some room rearranging so i could get enough room to cut it.
Just about managed :
First effort at covering in 10 oz hessian ( open weave upholstery fabric ). Probably stapled a bit tight. You will probably notice hailstones just starting. It turned into a torrential downpour just after i took these photos.
Kraft paper and 13 mm chicken wire visible on rear of panel.
Front of panel covered in chicken wire, poly wadding and hessian. As you can see i made the mistake of putting the cut corner ends of hessian on top of the rest of the hessian. I will put these underneath the full hessian covering so they are not visible on the rest of the panels and can be secured with the same staples used for the full covering.
There was no wood left to attach the hessian to the rear of the frame due to this been used to staple the chicken wire. I therefore had to trim it around the full length of the panel.
This first panel was actually one of the earlier heavier 1" x 2" frames ( i made two like this before thefruitfarmer made me realise they were unnecessarily heavy for wall hanging ) . They will be used to stand in a room corner.
As mentioned earlier, i covered both the front and rear faces with chicken wire with the intention of turning the panels around for different situations ( absorption for recording and semi reflection - paper - for mixing ).This would stop them sagging or coming out of the frame/losing their shape, but i don't think it is necessary to do both sides now as i have decided to leave the panels in place once fitted. I have decided this primarily because the chicken wire needs to be trimmed off at the 600 mm sides/ends of the panels in order to allow the fabric to be stapled there. As already mentioned by thefruitfarmer, this causes sharp ends of metal to protrude through the fabric. The excess chicken wire from tensioning on the 1200 mm sides can be compressed back into the frame without any loss of tension as long as enough staples are used on both sides. This is allowed by the fact that the 600mm wide chicken wire has metal strips at each side to avoid sharp ends. However at the cut ends this is obviously not the case. The only way i found around this problem was to leave a little excess wire and fold it over the corner of the wood with a hammer. I could not leave too much wire on the rear side as this is where the fabric needed to be stapled. If i just use chicken wire on one face, then this problem can be avoided by folding over a larger amount of wire, therefore reducing the chance of it sticking up.
I would love to know how Zukan and Max managed to wrap and staple fabric all around both faces of their thin wood panels which had chicken wire on both sides. Maybe they just did as i did ?
Also, i would like to thank both Zukan and Max for the SOS D.I.Y tutorial as it helped me to fit the chicken wire.
