.i had some bad thoughts about copper, but... works perfectly.
ingredients:
- THIN copper ribbon
-2 brass tubes(thin walled so one could fit another)
-piece of brass rod (goes into bigger tube)
-workshop garbage (brass handle, screw, leather, rubber wheel - as all ppl who have workshops we know that this part will be necceseray some day
)-hard soldering equipment
baking:
so what we are doing with this all stuff? first we need to know the lock if this will work. disassembly one, try overlifting all levers and move bolt. after this little research find two tubes that will enter each other and still will be able to enter the keyway(i had to buy one in model shop).
ok start. cut cooper with scissors to right size. one piece for levers and one piece for bolt. if you do it precisely you will have less work later. fold cooper in way that it will only once grab brass tube but will we 3 pieces of it in place for levers so it will be strong and durable(i hope you get the idea). repeat procedure for other tube. solder this stuff. file down what's not neccessary and distrupts smooth sliding. file down exact dimensions from cooper attachments. solder some brass rod to smaller tube and drill it. attach handle using a screw. i've put thin leather strap on bigger tube and attached rubber wheel to it firmly.
thoughts: adjusting took me 80% of time spend on this project. i've made it portable and didn't put "tensioners" for solid because i might need one of shafts for other lock so it will be dissasembling and adding some extras. utilitarism is my second name
. works great.photos:
