Of course the trick is to rotate the fitting, but I think a barrel sanding drum will solve that issue as there available in quite a few different sizes which I already have. I'll let you know...

I wondered the same thing (using a drill) but according to the articles I've read they use a router with an attachment specific to the item being spin welded. 30,000 rpm is the recommended speed to generate the friction/heat. From the way the weld looks, the plastic apparently gets hot enough to flow out away from the points of contact (much like metal flows when welding). Let us know what you find out.
I've watched several YouTube videos where they spin weld metal. If you haven't seen one do a search. It's fascinating.
