That should do it. The main problem is keeping the whole rotorhead assembly from falling off the balancer. Either need a long shaft or counterbalance weight or offset the height of the balancer wheel assemblies so shaft rests on top of one wheel unit and the bottom of the other wheel unit (through the hole in the side). Still would have to clamp the balancer stand down to keep everything from tipping over.

I used to use a long shaft that was turned on one end for 8mm and 10mm on the other end. Was made for the High Point balancer that the DuBro is a copy of.

I use a Dubro prop balancer for this purpose.

that is the one i just ordered from tower. good to know that it will work. do i need to clamp it down to use it with the rotor head? as stated by R.J. the weight of the head might tip it over.

If no blades you should be fine, If trying head balance with blades a weight on the base would be needed (something like weighing scale weights would be ideal)

count on having to use a C-clamp or vise-grip to hold it down to the bench.

Agreed - I use a Dubro Tru-Spin balancer and a spare main shaft to do this. You need to clamp the base of the balancer to the table and use a few very small pieces of balsa to lock the mixer arms and see-saw.

When doing it with baldes attached remember to first find the lead-lag center and lock them down at that point.

This procedure has worked great for me - smooth as silk!!

Oops - that's not what I meant to do!
