In an effort to get this project done I have taken to using those small amounts of spare time. Amazing what 30mins here and there adds up to in a week.
Not quite finished yet but not far off. I have run out of 3/16th" dome nuts for now...another trip to the hardware store. The first time the EQ head has been together for a few weeks too.
At a guess there is 25º of movement either side of centre...The knobs are out of Matti's bag of goodies, that included the RA gear and worm (via Zane I believe

)
Think I've gone mad with all the nuts etc....
A bit more cleaning up and a paint job coming up next.
