back in the 70's the first plaster I laboured for had one, then I went with another plaster and served my time, met new friends and one worked
in a machine shop using a laser cutter to cut stainless sheet, I drew him a sketch, told him what I wanted and gave him a little
coach bolt and butterfly nut, one dinner time he cut the bits for me.
I still use a bit of skirting and a oval or panel pin to rule off mostly but the square does make setting all window and door returns the same, easy.
shame there isn't an easy way to add a sketch on here.[/

Thanks for your info. Noseall has proposed a sketch facility be added to the forum,just for instances like this. Be great if it could happen.
