Can someone please explain how the trigger spring tool is used?

I used a soft covered twist tie to keep the trigger spring in place and also to hold the hammer forward while replacing the hammer spring/plunger.

I have the trigger spring tool but from my unskilled take on it the twist tie was much simpler use. Compressing the spring into that tool was a job. I guess I just don't understand how it is set up and used for the rebuild.

If you buy the book 'Craig Riesch' "U.S.M1 CARBINE, WARTIME PRODUCTION" North Cape Pub. Inc. it will help a lot. Around $20. I bought mine direct and didn't pay the Amazon markup.
You can take a nail the same dia. as the trigger pin, but short enough to fit in trigger housing. Put your trigger, sear, and spring together. Put in place and push the pin out with the trigger pin. This really helps.

Couldn't find a vid for the spring tool, but this method may be even better (FF to 55 seconds):

I've seen those tools listed anywhere from $4.95 to $25.00. I can't imagine how the $25 tool would be better than the $4.95 tool. I'm a tool-guy...have to have one of any kind for everything, but after handling the spring, I determined it would be pretty hard to cram up inside that tool. I passed on the opportunity and found the video mentioned by RASelkirk. Practice it a couple of times and it's almost easy.

I just use a loop of string. Loop it through the hole in the spring, drop the end thrugh the hole in the housing, then slowly pull the spring into place. Remove the string and you're done!
