Cant let that one go. Grinding the flange area of a Lakewood does "nothing" to it's ability to stop the granading clutch or wheel.
The scrapnel path is at the center of rotatal mass, probably near the center of the bell section. 1/4 hi-ten steel absorbs probably 20-50 times more energy that a stock piece of alum pot metal. If you have ever looked into the physics it is scary; at 6000rpm the radial velocity is over a 1000 fps. An exploding 30 lb wheel/clutch assy will produc several pounds fragments going faster than a 22 cal bullet. Now tell me cal would you rather have a piece of pot metal or a 1/4 piece of ballistic steel between the fragments and your leg. This is a capital no brainer.
I don't know were the Contemporary frame comes into the discussion of a scratch built frame. Moding or notching the frame is fine; discarding the protection of a scatter shield is foolish.
