I have a C8 with the byers worm gear but no tripod.

I am debating whether or not to spend money to get the tripod and wedge or if I should mount the scope on an eq mount.

I see a few used C8 mounts from deforked units for sale so I can only surmise that people have been deforking these.

But why?

I have seen a cg-5 and I find it hard to believe that its tiny gear sets perform better than the byers drive.

Even on bigger eq mounts, the gears are smaller.
How can they track more accurately with smaller gears?

Or do people defork them because they are too unstable with the stock tripod?

I think it has more to do with the polar hole with fork mounts..

People de fork for a whole variety of reasons.

Electronics failure on goto Alt Az scopes
Prefer to use a gem vs fork/wedge combination
Stability issues with a wedge (more weight displaced away from the center of the tripod)
Want something lighter to handle (heavy ota/fork/base combo vs. separate ota, gem, counterweight)
Want goto electronics
Want a greater variety of carrying capabilities for a 2nd or 3rd scope.
Don't like setting up and polar aligning a wedge
Mechanical issues with fork bearings when used on a wedge
Vibration issues with some fork arms

It's not that well known that the gears and motors in many fork mounted scopes are often the equal or better than those in most mid range gems (CGEM, EQ-6, etc.). There are many fork/wedge users who are passionate about their setups and with a little practice they get amazing imaging results.

I agree! My old 10" Lx200 classic would handle it's own tube + a 80mm scope mounted on it & still do a respectable job imaging at 1600mm. The CGEM I had was a flop trying to image at that focal length with just the 10" ota alone.
