High machining accuracy, mechanical stiffness and high natural frequency of vibration are...pardon the pun..paramount. Having a super accurate drive on a bowl of jelly is simply a recipe for astro-imaging misery.

Which is probably why the author, in the documentation on the website writes?
"It is not rational (and no cost-effective at all) to purchase TDM for low priced and weak quality beginner mounts. At the same time, if you have a sturdy and rigid hi-quality or semi-pro mount, the price of TDM is just on a gadget-price level. (The weakest mount which can be rational to use with TDM is the Synta/SkyWatcher EQ6 or Orion Atlas EQ-G. This is why there is no TDM adopter offered for cheap mounts.)"
