I purchased that same rotary. I just finished upgrading my WoodWorker to the Elite, and added this rotary to my setup. I did not use the stock motor, I purchased the Masso motor from OF and did the swap out. I mounted the Masso sideways and used a bigger belt as mentioned earlier in this thread. I just got it spinning and getting excited for my first carve, I could not have done it without the resources mentioned here. If you do swap out the stock stepper with a Masso, you may have a hard time getting the gear pully off of the shaft. In my case, I had to cut the shaft off and tap out the center so I could use it on the Masso.
