> I have a chain drive for my big rotating tower that was built by K8RR
> (SK). It has a torque limiter that allows the tower to slip in high winds
> to protect the rotor and linkage. The problem is that the adjustment nut
> for this limiter (similar to a clutch) has rusted solid and I can't adjust
> the tension anymore.
> My plan is to cut the nut off and use a new one, but I cannot find a

> But mine is a slightly different thread pattern and size. I need a 3 1/2
> inch nut with 12 tpi. The fastener places can't find one like that for me.
> Does anyone on this list have any ideas where to look?
> I can't identify the manufacturer of the torque limiter that I have.
