from outside flat to flat if using tube in a ring set.
If you are unsure ask

Custom Collapsible Mounts

If your tube needs altitude bearings, or you wish to upgrade to larger
altitude bearings we offer two sizes with our mounts:
12
inch outside diameter (left photo) full circle bearings. Hand holds
incorporated. Laminate applied to half the circle.
18
inch outside diameter (right photo) half circle bearings.. Hand hold
openings are incorporated. Laminate applied to entire half circle.
Bearings attach to your telescope through a 3/8" hole centered
in the bearing. Inside facing arced braces secure bearing to tube.
Or:
Bearings can attach to your existing ring set, on the drilled flats.
Or:
Bearings
can attach to outside of clamshell rings we supply. Allows repositioning
forward/back or rolled for focuser position.
We prefer large
altitude bearings - better balance changing eyepieces, finer incremental
altitude movement.
Adds
1.5" to the width of a mount.
Bottom
clamshell boards connected by heavy duty anodized aluminum piano hinge.
Top
boards secured with by thumbscrew transversally through 3/8" holes
into 1/4-20 wood insert. Cannot pull out.
Top of clamshell is 0.1875" separated to allow secure clamping
onto your tube. Add adhesive back felt or other cushioning if desired.

(18mm) Baltic Birch plywood is standard for wooden parts.
Altitude and azimuth bearing surfaces are Teflon and Formica Crystal
909-42 laminate.
All parts are included, assembly of kits is designed for very easy to
assemble; solid mounts usually use only 11 screws and 8 dowels.
Dowel are internal/hidden between abutting front, ground and side boards
