Do any of you fellas actually own Lado retract?... and if so, has anyone ever taken it apart to see how it works? I'm certain he is using a similar stall method in detecting end-points (full up/down positions), vice limit switches, etc...
Looking at mine, it appears that he riveted a circuit board across the two halves of the retract body, so I'm guessing that opening it up to see how it works equals never seeing it work again. If they were plentiful I would be tempted to send you one to open up. However, as you are aware....Doug is pretty much shut down at this point.
Depending on what you end up with for parts pricing, it may be worth it to purchase the air retracts and use your system to retro fit. Always nice to have SOME options out there.
