Hi Russlk ,
well ,respect to the mechanical parts I'm already trying to see how can I install it, but ,I'm not sure about the motor, i ask for some advice and some people tell me to use a simple motor like a fan or something ,but the problem is that the fan is A.C and i need a D.C motor ,however , I still looking for it , I look for something similar on internet and i think that a 24v motor will do the job.But if you know what motor can I use , I wil appreciate very much.
by the way, I'll prefer a door that opens like the supermarket. instead of the usual doors.
Thanks for your help!!
