Last night, I did find two great MCarbo videos. In an article by Lucas Schatzberg, Waldo (?) shows how to turn the swing once the punch is inserted. Works great’ asa spring compressor!
Problem I experience, all day long, is that when I get a decent amount of tension on the spring (before it is compressed sufficiently to install the remaining end cap or tool-less locking pin) the first end cap pops off because the spring clips can not maintain sufficient tension.
This makes me wonder if the spring clips will retain the end caps sufficiently when actually firing the Sub2000?
I have compressed the spring both 1) holding the base in my hand and also 2) gently in a vise.
Either way, the spring clips release tension just as they do if you simply pulled them 180 degrees apart.
