Well, the RFT is about done, down to just some tweaks and adjustments before she's ready for first light. I got the tube flocking installed late last week and put it all together. I still need to give the objective a thorough cleaning before final assembly. Here it is, all painted, assembled, and with the accessory bridge plate attached to the top of the tube rings. Note that I mounted it off-center, mostly to give my head more room next to the main tube, since my right eye is dominant and the one I use when using straight-through finders. It also gives me more room under the plate should I choose to use a hand knob to attach accessories instead of a machine screw. 55mm home-made finder in the foreground. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/110mm001_zps67b00... Here's a close-up of the accessory/bridge plate. 1/4" thick aluminum, with a 1/4" wide slot machined lengthwise (done with an ordinary router and carbide bit). The bottom of the slot has a 1/2" wide recess 1/8" deep running it's length, like commercial dovetail plates, to accomodate a washer under the screw head. Note the off-center position. I may change this to a centered position if I find drawbacks in practice (balance maybe). http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/110mm002_zps2f5e9... This shot shows my 50mm f/9 spotter (home-made from a surplus objective) mounted on the accessory plate, but any small scope, camera, or reflex sight can be mounted there. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/110mm003_zps665e9... The completion of this scope pretty much guarantees bad weather for a week or so. Sorry folks! ;-)
