I've been bugged about the relative chore of installing and removing the stock blade guard on my 21829 (BT3 clone) when switching between ripping and using my crosscut sled. I wanted the ease of removing the guard and having the Riving Knife stay put, a la Sharkguard, but already had a spare RK unit so decided to modify it and my full blade guard assembly to borrow from Lee's clever design.
I took both units to my chop saw, cut the top off the RK unit (so it sits ~1/8th inch under level with top teeth of blade), and cut the bottom off the full-up assembly (leaving enough for mounting on the RK unit), then cleaned up with grinder and files. Took an angle grinder to the top of the RK unit to cut slots, and drilled holes in the guard unit for short bolts with nuts.
The resulting combo works well - RK unit always stays on, and the guard unit slips on and off fairly quickly (presently requires a screwdriver to mount or remove). Pictures below, thanks for looking.
