Next up I took the lowered portion off the rear of the top side on the planer and filed a radius from the rear action flat onto the socket face. A quick look at this part of the action will show the need for the radius.

Then with a careful measurement I marked out to remove the majority of the wood to clear for the mag release lever anchor point which is the major "draw" that needs to fit tight so it was left proud and worried back as the smoked action was lowered into place by scraping with the bent file scraper.

With the draw roughed into place it was time to work on getting the action down into place. This bent and sharpened file (I ground off the teeth on both flats and edges befoe bending and sharpening) is almost indispensable for the job and far and away the most usefull way of working on the sides of the action inlet. I have previously used chisels etc to scrape but the bent file it the easiest to direct and use.
