You’ve gone through all the measuring and cutting to bring your 80% to 100%. Now it’s time to make everything work! Disclaimer.
Get your Dykem and files ready because they’ll be used a lot. I first realized I needed a little wider of a channel towards the bottom of each side. Basically to the line that came in the frame. I hand filed it down so I could get the slide to just barely fit.
I brought out my plastic hammer and gave everything a good whack. Dykem to see where you need to file down. After a LONG time and tons of hammering…
Remember to go all the way through (sorry fuzzy picture).
Once you can hammer everything, start with your coarsest grit lapping compound and start going at it again. Get through to the finest grit and it should feel like glass!
