Hi Jordy. Just a small piece of advice. Don't waste your money with the slow rpm motor. The motor you saw in mine at Greg's was same 34 rpm as the link he posted. When you think about using 10/32 all thread that's only 1" per minute,and it's way to slow. I upped it to 253 rpm 153 oz,in, same supplier and it will still lift over 30 lb, no problem. And it does it in about 20 seconds, much better. Just finished installing a micro switch on it for the down stop and it's running well. Been thinking about making a bronze nut for it as am not sure how long the furniture nut will last, as it's steel on steel. I covered the screw with heavy duty anti seize, but now it will probably pick up dust. On the plus side it sure runs smoother.
Hope this helps.
Rob
