Come Together

That’s what Larry, Mark, Steve and Dixon did on a recent afternoon at Mark’s workshop to continue the accretion of parts into a 40-inch telescope. Larry reports he can see his garage floor again, but Mark’s workshop floor has disappeared. Conservation of workroom floors in action.

This is the assembly day shoot for the rocker box.  The pier assembly is already in place and the rotating base is there as well, moving smoothly on the bogey rocker wheels that Larry designed. Today the A-frame that supports the rocker box is installed, and then the rocker box itself, which is held in place with  1.5″ shafts in pillow block bearings. Since we are still assembling and testing, instead of a secondary assembly we have a place to attach weights to give us a feel for how the rocker will move with the mirror installed and the secondary assembly installed. Notice the beautiful altitude bearing surfaces – 25″ circle sectors that the altitude drive wheels will move.

Nice smiles, guys!
