Telescope Reviews: Who can build me a fork mount?

Will try . Any particular emphasis ? My fork -to- trunnion setup has been to RTMC several times. It is based on a milling machine clamp design, with heel post fitting in a spherical socket made with a round burr ( Harbor Freight has some burrs). A photo might scare off some, as there are several adjustments. Setscrews, tapped holes, thumbscrews. All this to allow pressing a wide variety of diameters into the interior right angle of the 90 deg aluminum angle pieces sawn from aluminum angle extrusion. I did some milling also. There surely is a simpler way to hold trunnions in a vee, particularly for one size only of trunnion diameter.....wood block bored to size of trunnion?? I have done that with Delrin and aluminum blocks, which are tapped to accept retaining thumbscrews passing through one leg of the angle bracket attached to the fork arm. One could use threaded knife edge inserts in wood. The key to their use is a guide bolt sliding in a guide block with a relief hole to allow the insert to start threading when flush with the material into which it is to be threaded. The insert will thus thread in straight , as the bolt is turned.

The slotted PVC electrial conduit to Quick-Set Hercules or Gibraltar column, as a no -lathe- required azimuth bearing, is not fully explored, but I am certain that it will work. One can adjust the friction with hose clamps. It is note worthy that the cited Quick-Set tripods have elevating columns whose diameters match stock Delrin round stock diameters-- one need only saw off the length of Delrin required to take vertical loads and connect to the cross-member of the fork, perhaps add a Teflon washer, and surround this stub and some of the column with one or more (concentric) shell(s) of C- shaped lengths of PVC electrical conduit schedule 80 and/or 40, ff. Mr. Andrews' push-to parallelogram design. So far, I have fitted PVC to a Hercules column lubricated with Jig-A-Loo. A cross -bolt or setscrew(s) will join the PVC shell(s) to the vertical load bearing stub . A chop saw or miter saw will allow a clean, perpendicular cutoff of the plastic (or aluminum) stub, or have the plastic or aluminum dealer saw it. Lengthwise slotting of the the PVC electrical conduit seems potentially dangerous, so attention should be paid to proper fixtures, or saw it by hand. I lack a table saw. Plastic pipe contracts when sawn lengthwise, so can grab the blade when the cut is finishing.
