Very professional! I'm sure the final assembly will be a credit to you and should work very well!! Are you going to use a micrometer for grating adjustment? I've just re-done the system on my classic spectro to incorporate a digitial dial gauge and find it very easy to use. Worth considering. (The adjustable stop sets the grating to the zero image, re-set the digi dial to zero then move the arm to the calibrated position for the various lines in the spectrum.)
Keep us posted as you progress....
