I'm happy, too, they look great!  The little mini-hub spacers are a good idea, too!

Russ makes the most amazing trays and tripods! Believe me, I have seen them! The one Red Molly is riding on is gorgeous! His trays? Wow! And I’m not a fan of dobs but Russ’s 10” Cave Dob rebuild is wonderful, and you should see the Dob Dolly! :love:

As a final note on this tripod, I have done two things.

 

To hold the control pad, I made a little holder that fits into the tripod legs.  Velcro hold the pad to the holder.  I don't  have to worry about the wires knocking anything off of the tray.

 

When I first made this tripod, I couldn't locate a CG5 hub, so I made this from a piece of aluminum and some oak.  It turned out to be a very good and solid fix.

Today, I received a CG5 original hub for tripods, and within an hour I had it in place.  It doesn't look special, but it looks like it's suppose to.  I like this better than what I made. I just looks neat and simple.  (and I can repurpose the other hub on another mount.)

You can see the little square holder with Velcro to hold the control pad.

These are beautiful!

 

One thing I have to deal with at some point:  The tripod legs for my Tak NJP have cracks at the top where the bolts go through to hold it to the tripod head.  They're wonderfully solid mahogany legs.

 

I got an idea from an old surveyor's tripod that used to belong to Caltech.  The legs are pretty thin at the top where they attach to the head, so what the makers did to prevent splitting along the grain was to cut a saw kerf right through the middle of the end of each leg, and glue a sliver of wood of the same thickness into the kerf with the grain running 90 degrees to the leg grain.  No splits, and the tripod has to be at least 50 years old.

Another great idea, Gary.  I was actually thinking of something similar for my drive controller and battery pack, but I was going to leave the through-block bolted to the controller, which would make it bulkier and oddly shaped.  Your removable Velcro attachment point is much more flexible and can be left on the tripod.  Nice job!

I have made several tripods, from small to some for 6" F15 refractors. The following pictures show the tapered brass pieces I made for the missing one on the bottom of the tripod feet, along with the steel piece to dig in the dirt and keep the tripod stable. I also made the brass bolts to hold the legs to the top. Of course I kept the originals, labeled and tagged, along with the rest of the Clark equipment. I did not alter the original in any way to add these. The other pictures show a dovetail system I designed and made to hold both the 4" and the 6" F15 Clark refractors on the Astro-Physics 1200 mount.
