These mounts are designed with preset sizes to accommodate any
telescope tubes from 8" to 12.5" outside diameter with
up to 23" rocker box swing-through room. We do not modify
this design; if you have a larger diameter tube or require more
rocker box swing through room please see our custom mounts.
Fitting requirement maximums:
box swing through room.
Internal dowels in predrilled holes connect the front board, side
boards and bottom board making them immovable while providing
excellent strength and stiffness. Boards are also secured with
#12 wood screws hiding the dowels and locking them in place. Wood
parts arrive rough sanded using 80 grit.
Altitude bearing construction: Tube facing side of each
bearing has two attached curved braces custom cut to match the
outside diameter of your telescope tube. A 3/8" bolt passes
through the center hole of the bearing into the telescope tube
(you must drill a 3/8" hole in the tube), clamping the bearings
securely to the tube using a washer and nut on the bolt inside
the tube. Bearings ride on teflon pads on supports inside the
sideboard walls preventing lateral slippage and allowing mount
and telescope to be lifted as a single unit.
All parts included: 18 mm Baltic Birch plywood mount parts,
dowels, screws and other necessary hardware except 3/8" bolt
assembly. Bearing surfaces virgin Teflon and Formica
laminate Crystal 909.
All screw holes predrilled and countersunk. Required items: 3/8"
bolt, washer, nut, sandpaper, Philips screwdriver, wood glue,
wood putty, contact cement, paint/finish.
