I just received a bolex h16 with all the bells and whistles etc including a rexofader.

 

I cranked the camera with the levers at MOT and I, 24fps and then I hit the trigger.. absolutely nothing, is the spring busted? 

 

I've been prowling the forums and manuals, and can't quite figure out the problem?

Not necessarily a broken spring, could be something jamming the mechanism.

 

First thing I would do is see if you can manually advance the mechanism. Remove the fader. Switch the lever from MOT to O, and lock the run release to M. Then use the rewind crank in the 1:1 or 8:1 shaft to advance (or rewind) the mechanism. If you don't have a rewind crank use something that will locate in those shafts without damaging them, maybe flat end pliers, or file a slot in the right size tubing and drill a hole in the other end for a rod handle. You might find a tight spot needs to be overcome due to something embedded in gear teeth, or the mechanism was gummed somewhere enough to overpower the spring. If it won't advance easily, don't force it, it will need to be looked at by a repairman. Avoid opening the camera up yourself if the spring is fully wound.

When you say you cranked the camera you mean you wound the spring, no? If so, the spring is not the problem.

 

I suspect somebody tinkered with the camera, loosened the screw on the T-I lever, and now the stop-start wheel is jammed.

Try to pull it up with the aid of a long M2 screw in there, wiggling the side release button in both directions. Once the axle flush with the guide bush lay the lever on the square top and put the original screw back.

wound yes, I tried the rewind crank - still nothing - and nothing seemed to happen when I played with the T-I lever

 

I guess I'll take it by a repair tech

How wise of you, best wishes, and let us know what caused the trouble.
