I almost have the actuator fabricated it's as close to yours as I could get working from Pictures.
Some measurements of the main guide rail would be nice I think I have mine a little long! Also the length of the inside piece that slides in the main guide rail.
Also I can't figure out how the spring is mounted on the inside piece that slides in the main guide rail.
And last and most important how did you wire up the motor so it would stop and reverse at the end of it's travel I know that reversing the wires will make it reverse also what voltage do I use for the motor.
As for the door Thank you for clearing up a big mystery about those guide rails I have racked my brain tring to figure out how to bend those sweeping 90 degree bends.
Also for the door I almost have the hinges figured out I may need your help on those.
Love your work this is the first time I have tried to do something like this and I am enjoying it.
