Building a Harmonic Balancer installer V1.0

Does the bearing allow it to go on without having to wedge something in the fly wheel? This is so bizarre. I just got a piece of all thread and bolt, washers etc. from work. I also thought about using the bearings. Not sure if I still have any laying around. Thanks.
Don't understand the flywheel reference, this is built for the front harmonic balancer install on any engine with a 3/4 NF female thread in the front of the crankshaft. The bearing is a must have component of the system as it allows the nut to turn without undue friction on the washers driving the balancer on the crankshaft.
I just looked at the photos of the $90.00 universal ones and figured I could do better. One improvement over mine would be to have a hardned nut but for casual work, this works fine. Did a really nice job on my install which is detailed in another thread in the small block section. Thanks for the kind comments all and happy DST weekend-------------DR----O:)
