Thank you! your comments mean a lot! All I used was a vice, a file (both standard flat and round key file), a 9.5mm drill for the mounting hole and a 2mm and 4mm drill for the design.
I used double sided tape and taped my design (the 1:1 scale helped) onto the cheap ruler, then cut off the excess metal with a hacksaw and filed back to the lines and used a right-edge to check everything is squared off. I then used a center-pop to mark the holes for the drilling and drilled out the holes starting small with a pilot hole and expanding.
After it was filed to size and drilled, I used a belt sander (it can be done by hand) and sanded off the ruler markings and numbers and put a slight radius on the front then removed the burrs from the back.
For the bending I mounted it in the soft jaws (Aluminium sheet bent around the jaws in the vice) then used a block of wood and a hammer to bend the clip into shape getting a nice radius and avoiding breaking the metal! after that its done! just sand it back with fine sandpaper and I used a polishing wheel to get the final shine on it!
Took around an hour to do and makes a nice afternoon project! If you want to make one yourself I posted a linky to my design above and you can use my basic measurements to get the basic shape or copy my design all together
! Either way, good luck! and any questions just ask!
