I turned these knobs from 40mm stock on a manual lathe during the week, and JI cnc-milled them to shape today.
There's still one bit missing from the wedge: the fine-adjustment piece for the azimuth-angle during polar alignment. I'll try to make it on the lathe next, and then everything should be ready for anodizing.
This is the top plate of the wedge which will be tilted so that the alt/az mount which is bolted to it has its azimuth axis pointing towards the celestial north pole. The side-plates will have to wait until next weekend.
I'm building an equatorial wedge which will transform my new alt/az goto-mount into an equatorial mount. This is the first part which attaches to the tripod. Two smaller side plates will be bolted to this plate and support a similarly shaped tilted plate to which the alt/az head attaches. The design is similar to the "mega wedge pro" (how about that for a product name!).
