Ron had us make a mount with bearings for his 10", and clamshell rings with bearings for his 6" to fit the 10" mount: "Stand arrived this evening. Great job! Looks super, works great. The most amazing part is that it weighs 1/1,000th the weight of the original Orion stand!! Geez!! The real reason that I wanted the mount, so I could put my 6" to good use also.

Mounts have round ground boards and are designed for minimum height. Additional height for a more comfortable viewing position upon request. Parts are CNC cut for uniformity and precise fit.

Solid Mounts: Side and front boards are screwed together and contain internal dowels adding stiffness.
Tall solid mounts may have curved internal or external stiffeners for rigidity.

Collapsible Mounts save storage space and fit easily in your car. Collapsible mount boards are all attached as single unit with heavy duty anodized aluminum hinges, fold flat to 5" height and sets up in minutes. No loose parts; all knobs store securely on the rocker box bottom board.

Kit orders are predrilled with all parts included. Wood parts rough sanded with 80 grit. Teflon pieces precut, countersunk and come with screws.
Formica laminate Crystal 42 bearing strips and azimuth ring are precut to size. Parts are dry-fitted before shipping. Requires fine sanding, Philips screwdriver, 2 wrenches, glue, wood putty and paint/finish..

Finished orders arrive assembled.

New: All altitude bearings ride on supports mounted on the side boards instead of our old style on top of the side boards. This prevents lateral slip by capturing the bearings.

Tube fitting bearings have inside supports with an arc cut to fit the outside diameter of your telescope tube, and require a 3/8" bolt hole in your tube to secure it. Bearing thickness is .708". Small bearings are up to 12" diameter. Large bearings available up to 24" diameter.

Clamshell rings provide 1/8" gap around the tube (1/16" on any side). Line the inside of the rings with adhesive backed felt or weather-stripping to obtain desired fit. The clamshell rings two bottom boards are joined with heavy duty anodized piano hinge. The two top board open, and secure together using a thumb screw passing through one board and screws into an anchor seated in the adjacent board. Altitude bearings are diameter of your telescope tube (up to 12").

Finished and assembled mounts can be shipped to US and Canada. Finished but unassembled mounts and Kits can be shipped worldwide.

Materials: 18mm Baltic Birch plywood, virgin Teflon, Ebony Star replacement Crystal 42 Formica laminate and assorted hardware. Finished mounts have up to four coats of fine sprayed polymer sealer with a cinnamon (reddish) tint.
