I think I solved that problem with a teeny peristaltic pump and a couple of timers rigged to be variable excitation for a mister.
Now I'm in the plotting stage of motorizing a BS-1 clone. Mounting a motor on the rear with a belt drive to the center of the tilt axis, then a gear from there to the worm. And I don't even have the idler shaft for the middle of the tilt axis made yet, nor have I drilled and tapped that hole in the side of it yet. Waiting on more ats-667's, which I got today. But with the woof in the shop, I need to organize getting her 401-k disbursement going to pay the shop bill till whenever... End stage COPD. And I'm running on a 31% pump so I'm not as fast as you younger whippersnappers.
