Also at the stern on the starboard side are two uplift doors, the rearmost is to deploy the oil spill recovery skimmer, this is operable on my boat and as will be the recovery float. The one next to it is for launching the ROV, this is fixed down.
So between getting deeply involved in arduino sketches (operating code) I have been lately working on the lifting door for this part of the build. So far I have redone the hinge parts 3 times and they still won't operate. I had no real drawing that I could take measurement from, just an artist sketch and a photo. The real world hinge certaintly won't work in the model for sure! I cannot get the hinge to swing the door clear of the hull, it catches/seizes in the top of the recess, but I will plug on...
The photo shows the door partially completed - still more bracing to add to the inside. The hinge pivot can be seen with gear drive that will engage a similar one on a micro servo, which I have gutted to leave the motor and drive gear so it is continuous rotation. forward and backward drive of the motor is done by arduino.
