Last winter I built an 18" cabine from a IMBEL "brazillian" kit and an IMBEL Reciever. I used Gunplumbers instructions as well as lots of help from the falfiles.com.
Total tooling probably cost me less than $30. I made my reciever wrench from high density non maring plastic discarded by our tool makers at work. I bought a cheap 1 1/16" wrench from Ace hardware and filed it to fit the barrel flats. I chopped the barrel with hacksaw and crowned it ala "
Gary Jeter" (the king of WESCOG).
I borrowed a sandblaster and compressor and bought two bags of playground sand and blasted everything clean out the back of my garage. I parkerized all the metal using brownells mag park chemicals and a 3 gallon stainless pot from the dollar store on my coleman stove. The barrel parked in a wallpaper tray from home depot.
I found a guy who lived nearby that had headspace gauges and was willing to double check my headspaceing. It was right on. I had used a round of match ammo as my go and match ammo plus masking tape as nogo.
All the plastic was done in bedliner and OD paint.
Overall, it was a blast to work on and I'd do it again. However--I have close to 40hours into the FAL. My AR 15 only took about 1.5-2hrs to assemble from parts (including barreling).
To fun comes when you touch off those first few rounds from a rifle you completly built up with improvised tools and finishing methods and it works perfectly and looks great.
If you have any questions about where to get stuff, or improvising tools, let me know.
Its a great project for the winter.
