Quote:Am I correct in saying that the Celestron CG-5, EQ-4 and Skyview Pro mounts are practically identical?
Quote:I have read somewhere that the LXD55 RA and DEC motors can be attached directly to these mounts giving them GOTO ability.
Quote:Here's what a Goto4All conversion looks like on the SVP mount.
Quote:...grind a little off the side of the RA housing for the spur gear and I'm set.
Quote:Well, a little plastic trimming and I think the RA motor will fit after all, now I just have to get a shorter motor mounting screw and grind a little off the side of the RA housing for the spur gear and I'm set.
I'll post a pic when I'm done.
Quote:What about just using new spur gears of different sizes, bigger on the motor and smaller on the worm gear? I know I'd have to compute the ratio and set it in the autostar controller.
Quote:Worm shaft side bore is 6mm for LXD/SVP (7mm for EQ6).......LXD motor shaft is 5mm.
The one show stopper that may rule out pulleys is that I want anything I use to fit inside the LXD55 motor housing, and there's not much room for anything wider than the spur gears already there (~10mm or so total on the shaft). The pulleys at the link from ccs_hello are 17mm wide.
Quote:There is a solution: Dremmel tools against the housing.
Quote:Quote:Worm shaft side bore is 6mm for LXD/SVP (7mm for EQ6).......LXD motor shaft is 5mm.Speaking of the EQ6/Atlas... that belt drive mod using the LXD55 motors ..... a set of belts and pulleys would cost in that configuration?Charlie
Quote:I think I'm going to bite the bullet and grind the mount.
Quote: Not to harp on the subject, but you are planning on taking the mount apart first, right?
Quote:Timing belt, e.g., 40 grooves (https://sdp-si.com/ss/PDF/26501007.PDF)choose Kevlar cord, metric 6mm wide A6B16M 040 060.Replace the 040 number with whatever grooves you need to fit.
Quote:Another idea is to change the motor mounting hole such that motor can be moved further apart after the belt is installed.
I should take this opportunity to recognize RoboScope and EQ6 groups' efforts on mount GOTO mods.
