For 2 weeks almost now it has been cloudy and raining here in Northeast Ohio. I have a newtonian that I wish to collimate, and still wish to do some photography with it as well as with the 127mm. Last month, we got over 6 inches of rain, when we average about 3 1/2 inches for April.
I have also been thinking about building a larger mount. Being the 127mm is homebuilt, I thought it fitting to build the mount as well. If I can figure one out, using wood and common steel without the need for a metal turning lathe, I may go ahead with a longer focus refractor. The reason I went with the short focus refractor is because I didnt think that my current mount would hold a larger scope. The 114mm Newtonian is almost too big for the mount I currently have. Therefore, if I can build a mount that the 114mm fits comfortably, perhaps I'll build a 127mm X 1200mm focal length scope. I figure a scope of that size would provide good planetary views.
There are some good wood based equatorial mounts online. I would probably base what I would build around one of them, but with some modification. One thing I would like to do is use some ball bearings in the mount to allow it to operate smoothly. The hardest part however would be rigging up a clock drive to whatever I decide to build.
Perhaps I'd be better off buying a CG5 class of mount.
