Is the taper lock hub something that one can buy? Can a machine shop make this?

Yes you can buy a taper lock at any bearing supply or industrial supply house and if you google I bet you can order them online.
I get a lot of stuff from WW Granger and another is McMaster Carr and I like Bailey Sales out of Knoxville Tn. And if you like gadgets ets "The Suplus Center" has a free catalong with generators and tons of stuff.
Look up "Browning" I think they make the "Taper Lock" brand
Also rember you can order hubs and bushings in different lengths as well as different bores. Order as long or deep a hub you can use as it will give you greater holding power using more surface.
Another is Northern Hydraulics Industrial catalog

Thanks, Tim. I see some on the Grainger website. Please correct me if my understanding of them is wrong:

I will take my shaft, which is 25mm and have the rotor hub made to just fit over it. The rotor hub and shaft can have a key lock. Behind the rotor hub will be a taper-lock hub. There will be a taper-lock hub in front. This will squeeze the hub together. As an alternate method can I have the shaft taper slightly larger so the rotor hub gets tighter the further down the shaft it is pushed?

The taper lock hub works by using the screws to squeeze the internal ring tightly around the shaft so friction keeps them together.

For the F&P go to randysworkshop.com he has some laser cut plates that adapt blades securely to the F&P hubs

I looked into this, but Randy doesn't have the hub for the blades I'm getting. He said he couldn't help.

You can bore your existing hub(if it is large enough) to accept a stock weld in hub that will take a taper lock bushing.
Or a shop could taper bore your hub and drill it and thread it so it would take a Taper lock bushing to.

I think this is what I am going to do. The shaft is 25mm. I can bore the rotor hub to take the shaft and key. I can bore the shaft in front down to 0.875 to take a standard 0.875in bushing taper lock from grainger.com

Will 0.875 steel shaft be ok for an 8.5' rotor?

Jonathan,

As one inch is 25.404 mm you should have no problem finding a taper lock to go with your 25.00 mm shaft.

dom We only ever use the best fencing wire for our repairs!

Taper lock hubs are used everywhere. Any bearing supplier should have them. You can find hubs with taper locks that you can weld on sprockets, pulleys, disks, etc as well.
