Hi All,
I thought I would post this for anyone who has an old C8 fork mount lying around that thinks it has seen its last days of usefulness. In the fork configuration the mount is good for only a C8 OTA, but converted to a GEM it can be useful for just about any OTA that has a dovetail. Anyone with a small to medium refractor (120mm F8.3 refractor shown) or Cassegrain OTA can make a nice solid mount for minimum cost utilizing most of the existing mount components (tripod, wedge, base, etc). You can usually get an old C8 mount cheap on Amart or CN.
The parts for the conversion are easy to make. I left the aluminum unpainted so that the mod components are clearly seen. I believe high grade plywood can replace the aluminum components if necessary. I would recommend 3/4" thick as a minimum. I can go into more detail if anyone is interested. Please note: Meade mounts are not recommended for this modification. Meade made the attachment area for their forks tapered. Not worth the trouble to try to match the taper.
I have higher resolution shots for anyone interested in such a project for themselves. Shoot me a PM (
[email protected])and I will gladly send them to you. CAD files are available as well if you have a CAD program that will read in DXF format.
***If anyone out there has a couple of C-14 fork mounts that are collecting dust, drop me a line. I would be willing to convert your two mounts to GEM. The cost? I get to keep one. Any takers?
