Forward toggle link

The rear of the frame will always be touched by the rear toggle link, as the inside will always be touched by the firing pin retainer.

A good test to see whether the spring is right is the 'tape test'. Stick a small piece of masking tape (paper tape) to the rear of the frame and fire a round. When the spring is correct, there should be an indentation in the tape, but the tape must not be torn.

-Paper torn: Spring too weak/ load to powerful
-Paper dented: All is fine.
-Paper not touched or hardly touched: Spring too strong / load to weak.

One of my VoPo DWM frames had such excessive wear on the toggle ramps that they were not only polished clean, but deformations to the frame ears could be observed with the naked eye. One of the reasons why that portion of th ears was hardened seperately later on (see Krieghoffs).
