I will build a curved 120" wide (130" diag.) 2.37 SMX screen. additionally, I have been thinking of using that exact same track actuator from this website:http://www.firgelliauto.com/product_...roducts_id=108
I have a few questions for you:
1. How stable is it?
2. What kind of bearing is it?
3. How is the remote control working out?
4. Is the displacement smooth?
5. Fabrication details for mount?
The actuator is rated at 400 lbs and is very stable based on the actuator mount. The sled carrier surrounds the metal frame that encloses the ball screw so there is no failure that could cause the lens to fall off the actuator. The only issue is the fact the carrier is plastic however, its size and the limited amount of cycles that this application requires , should not have a wear issue. The mount for the actuator is made from 1.5 and 2.0 inch schedule 40 pipe and is welded construction. The interface between each section is secured by dual internal wrench set screws.
The pendant remote works fine but will install a remote control system that works with my MX 3000. In operation the tracking is very smooth.
Since I made the mount form scratch I did not make any drawings. Best I could do is detailed pictures. If you are capable of basic fabrication skills most could handle it. As in most DYI designs there are several changes I would make. One, the travel on mine is longer than required to position the lens from in front of the PJ lens. I plan to install an external limit switch to resolve this.
If you need addiitonal info just send me a pm.
