A friend from work wanted to break into astronomy and purchased some nice binocs. I still had a stash of mahogany available for some small projects so we decided to build some mounts like the one for my brother. Only this time I didn't have the tripod hand-me-down from the son's 4.5" reflector. So I opted to build the twin mounts from scratch. I designed them in SolidWorks first.

an adjustable leg                                the tripod                                   the business end of the tripod head                       the business end of the pan head

                                                                the full assembly

Then I fired up the table saw and drill and started cobbling things together:

I used some galvanized sheet metal/flashing to make two sleeves for each adjustable leg. One is attached to the outer rails and one is attached to the central sliding leg. Works great!

1/4-20 hardware and #8 woodscrews throughout the construction.  Very solid. Some assembly still to go and weatherproofing. Need to find or build some extensions to connect the pan/swivel heads with the horizontal hole on the binocs (an "L" bracket of sorts).
