I have gone away from the traditional use of encoders. I have pictures of my encoder arrangement very simple concept and instead of using a fixed encoder for ALT I am using an Inclonometer instead specs here.

This avoids drilling any holes at all. As shown in my picture, I use 3M pull off double sided sticky for just about everything. The stuff i use it oversecure and as i have done on numerous occasion while experiemtenting was to remove and replace with soooooo much ease.
It is a bit harder on the AZ encoder but for the that I have done the same although I will be machining simple special adaption to allow temporary and accurate fitting as well as removal of encoders.
The electronics, I am redesigning sorry no pictures. I also hope to manfacturer a number of these to give a lower cost alternative in different stage in partial DIY to full production.
Before I do that I need to make sure that I cover all step to ensure the consumer is getting the best solution as well as easy to fit.
The USB to Serial convertor is crap but effective, The problem is these annoying blue lights that flash during communications EUGH.
I hope to make 3 designs, first is the pure serial, the USB and finally Bluetooth. All of these are highly acheivable in my design as a complete unit and not put together in a mess.
I am limited by funds a bit at the moment, my wife on a disability support pension is unable to assist and Centrelink require my buisness to run at either no profit or a loss until she is off the pension. A lot harder than you think.
Overall I think it can be a lovely Push to Project, I have tested it with CDC and Worldwide Telescope along with Scope.exe
