once you have the basic shape put it in a helping hand and carefully solder the edges together to stop it coming apart(don't go to far up or you'll solder the rod/tube to the hinge Not good)




clean of any remaining solder so it's nice and flat and pop it in a vice (i use ally angle as it keeps a nice sharp edge)



remove the rod/tube and mark up the hinge to look how you want it then carefully dremel/file out the waste clean of the burr and re-try the rod/tube




now you have one hinge side follow the same steps for the other side and align the two parts and mark off the waste on the other side and cut out the same as the first. try it with the other side and see if it fits a bit of careful fileing dremaelling and alls good to go fit the rod/tube to the two parts and now you have your own scale hinge
