Well... Let's see if we can turn this scope into a "REAL" C-14 wink

All done! New decals applied. Home made short dew shield/dust shield installed. It has been fun. Now this thread can go into the sunset (to the relief of some I'm sure wink ).

What have you started making today?

Posted By Keith Lawson
Neat machine work. Not to downplay the cool cell, I couldn't help but notice your "old school" lathe. I have worked with some high end iron in my machining career but I have a fondness for the older machines and the unique skill level required to operate them efficiently and safely. Impressive. I learned machining on similar lathes and mills. Good luck with your project and please keep us updated on your progress.

Here is an MDF Wedge I made for my cooled C8. It dampens better than my aluminum wedge. Added to my modified (center pull) Meade HD tripod (12" to 14" SCT) the system is now much more stable than the original C8 wedge and tripod setup. Tinkering and having fun. 8)

I forgot to add the basic design print for those interested in implementing this Mod for their scopes. I can make available the full print with parts and dimensions if needed. This is not for newbies! Enter at your own risk! Mod not recommended for deep sky observing, SCT's with "average" optics or for those who do not know how to collimate their C8 at focus with a high power eyepiece (200x or greater).

Anyone interested in the radius block (the most difficult part to make) can send me a PM and we can talk about having one made for you (nominal fee). The fan and cover channel material are available through McMaster-Carr. I have the part numbers. The 12v rechargeable power pack is an Amazon item. Please, experienced ATM's only! I'm not looking to produce all the components of this mod. I'm just offering to help anyone interested in performing this mod.

Note: My lowly "Plug & Play" C8 does not have to run and hide when the APO guys show up at a star party 8) Astronomical seeing is my only observing enemy smile
