Sorry about that, I left a few things out. The coil spring for the ejector is sort of a trial and error deal. once you have cut the notches for it you can try different rate springs until you get the results you want but make sure you avoid coil bind. Once you have found the right tension solder the spring in place, clean up the flux and excess solder and you are done. I usually use a rather heavy spring here, one thet gives me about the same tension as a 98 Mauser ejector or a bit more for the big stuff like the 416 Rigby and such.
There is nothing wrong with cock on closing but I like cock on opening so I convert the Enfields to this. Dayton Traster has a good cock on opening kit which comes with a new cocking piece, fast lock time spring and clear directions and a template for cutting the camming surface of the bolt. I have in the past used their trigger but not since I had one where the sear was not properly hardened and it rounded off to the point where the rifle would at times fire when the safety war taken off so a word to the wise here!!!! Timney has a good trigger that will work with the Dayton cock on opening conversion so that is the way I would go. If you want to do your own cock on opening conversion you can but for reliable ignition you must go to a fast lock time main spring in the 24 pound range. I hope I have been of some help with your questions.
