Thought people would be interested in the simple tool (two bits of 3mm thick bar with notches) I have made for compressing the new door springs I bought a while back. The extra notches and holes were earlier attempts.

Tried to do it with vice and cable ties previously following Fen Fulvia's method, but it was a bit fraught, since the springs are pretty heaving duty.

I found one of the old ones broken in the frame. I hadn't realised they were missing
