CFFD - Chain Front Freewheel Drive

I've been a v-belt drive kinda guy for awhile now, but then got into friction.
Now I'm onto chain drive & wanted to assemble something quick and easy without spending any new money.
I sheared a drum from its shaft on my Dax friction driver & while waiting for the replacement, decided to slap this thing together.
-Its my old racing MTB (Litespeed Obed titanium frame)
-Spread a cheap cromo fork 20mm's
-Install a rear wheel into the fork (thread-on 34T freewheel)
-Mount pocket bike 5:1 transmission (10T)
-run std BMX chain 1/2" x 1/8" (410)
It freewheels which none of my previous project have done. I think this will be better for the engine (no engine braking) & greatly improve clutch wear & clutch spring failures.
I'm planning another future project that will run a chain from a rear rack mounted engine straight to the rear cassettes' big ring & then another chain from the other 8 shiftable gears to a front freewheel single ring.
Here are the pics

Heres a very rough pic of what I'm getting ready to do.
There will be a freewheel crank with 2 chainrings on it, a 9 speed rear cassette w/ front & rear derailleurs & the same pocketbike transmission with Dax drive channel as being used on the front of this bike but locted on the back of a full suspension DH bike. All the parts have been ordered & are coming within a week...
