Current Projects chat and miscellany

I was thinking about a bodge to work on a lever without springs and thought about threading a small amount of brake cable through the lever with maybe 2cms sticking out the back, putting a small diameter but long spring on there (like those you get in a biro but tougher), compressing that spring and crimping a brake cable end on to hold the spring in tension. Reckon that might work?

I had identical thoughts (even down to the biro spring), but the work area is a bit cramped and I wanted something which was going to have zero projection from the lever body. There might be a bit more space to work with on Shimano levers.
