Source for heavy-duty flexible drive?

[Dataguy]

So I have an idea for a power unit that could transfer power to multiple different tools (one at a time) via a flexible drive like the ones you can use with a Dremel tool. Anyone know where such a thing could be found? I have an 8-hp gasoline engine I'm planning on using as the power source, so it would need to be fairly hefty.

Eastwood used to have a flex shaft that would attach to an electric motor that would the attach to a buffing wheel. I can't find it online. I will try some of my old Eastwood catalogs.

Can't find the part number online, must have been discontinued.
