Customer Comments

Patrick Sutton's outstanding 8" Dobsonian on our solid mount with clamshell rings, altitude bearings and tube end rings. Thank you Patrick!

"Mark worked tirelessly with me on my mount project. I had many ideas for customization and changes that I wanted to make and he worked with me on every single aspect of it. He would not rest until I was satisfied and his attention to detail and commitment to his customers is truly amazing. Thank you again for everything you did, Mark. I am truly grateful and very happy with my mount"

Joe M. just received his new Big Bearings and sent these photos and comments:

"Hi Mark. I got the new side bearings you made. They work great. I even raised the bearing by an inch and a half to make the eyepiece easier to reach. -- Joe M.   

Big Bearings attach to your existing 5" or 5.5" bearings to provide a 12" bearing surface. The FRP bearing surface rides on teflon pads attached to a matched support mounted to the outside of your current side boards. Eliminate the clumsy kludgy springs, counterweights or tightening knobs. Big Bearings provide excellent balance while much larger diameter greatly improves altitude control.

Inexpensive 6" Mirror Cells

Stong and lightweight, these 6" three point mirror cells are made of rigid 3/4" baltic birch plywood. Measurement is 2.125" from the mirrro to back of cell, with collimiation knobs extending 15/16". Outside diameter is 7-3/4" including mirror clips. Mount using 1/4-20 bolts and lock-nuts. We calculate the best support position and place adhesive backed pads for your mirror's specifications.
