I have have change many FFPW rims with no chains, no rim upside down, and filling air using a short air nozzle while facing the rim with no issues. The FFPW lock rim is not the old style that is a continuous ring that you have to work over the rim and hold in place to lock, those are the deadly ones that require cages to hold everything in when they explode.
If you look at the lock ring, it goes into the rim's ring groove and is held by the flat surface area on the ring/rim and the lock ring has plenty of tension to hold itself in the groove and in place. Like Johnd mentioned, it need to be free of rusted iron to fully seat and hold safely in place.
- The tube - I've never used Talcum powder installing a tube, but some do. Once you install the tube and flap in the tire air it up to expand the tube, let the air out and run your fingers between the flap and tire to make sure the flap lays flat, you don't want any flap folds.
Installing the ring - Once ring and groove are cleaned, use a piece of hardwood and 4 or 5 pound hammer to lock the ring in place. Get one end of the ring in the groove, hold your foot on it to keep it place, place the wood 4 or 5 inches away from your foot on the ring and strike it with a hammer, repeat working your way around the rim. No need to hammer the ring, it seats just fine.
- Talcum Power - if you notice, the tire bead will be basically at the bottom of the ring. Here you can apply some powder on the ring to facilitate the tire sliding up the ring. Once the tire starts up, it locks the ring in place. It's a very safe rim.
I have no input on the 8 lug.
