: Anyone have any good suggestions for altitude bearings on a dob base I'm building? Don't like the idea of laminate or aluminum wrapped wood, Found a guy who will mill me two aluminum discs(6"), for $150. But I would like to find something to use as an alternative for less money. They will ride on teflon. : Just thought I'd throw this one out there to you guys and hope for the best. Thanks and clear skies! : Rich : P.S.- It's a 10" F-7, (good size scope)

Try plastic tupperware round containers, or coffee cans, cut down to a depth of about an inch or so ,then glue a wood disc inside of can to add support,due to the weight of the tube assembly,otherwise the plastic or tin will bend,then attach to the tube box by drilling 3 or 4 holes through bearing and insert hex bolts & nuts(or glue to box and wood screws). also nylon pads work good too..........steve.
