Last January I got a call from the Astronomy Club of Akron, of which I'm a member but don't often have time to participate, in regards to a 1968, 10'6" Ash Dome that was donated to the club by a wonderful lady who's husband unfortunately had passed away a few years ago. The club didn't have a need for the dome and asked if I could remove it.
Freddy Huffman, a long standing, very active club member and I went to have a look. the Ash had been neglected for quite some time. Wasp nests and old axle grease filled the tracks and rails which prevented the motors from doing their thing and the dome had been painted with that aluminum RV paint which was no longer holding up. This would be a project.
We went out and dis assembled the dome in April. I wasn't able to take pics because it was pouring down rain.
Next the Ash was sand blasted, sanded, degreased and scrubbed down to get it back, as close to possible to it's original glory.
Since I picked up the Meade 178ED, my old Sirius Dome was just too small so we figured the Ash should replace it.
Here's the HOC as it used to be.

My son, Jason and I removed the Sirius and replaced some decking.

Rusty came out for our star party, BEOTS, a few days early to lend a hand. Building round stuff out of square lumber is always interesting.

The next evening we had the dome installed and the shutter motor in. The following morning Rusty put the rotation motor in while Jay and I put the siding on.

Scott, what a magnificent Dome! It's so good to see something of this calibur rescued, & restored; couldn't think of a better place or family to give it a new beginning!

Thanks guys. I really like the old classic stuff. I'll never part with the 1970ish 12.5 f/8.
It was a lot of work but this thing was made to last. It just needed some TLC and now I think it's ready to work for another 40 years.
It really did clean up nicely

Of course it wouldn't be complete without displaying the sign that Mike Lewis had made for us.

I had thought about putting up an 11'6" Sirius that I had but the lower shutter design hinges out so it would hit the "Tardis" observatory when it rotated.
The Ash is designed so the lower shutter detatches for viewing near zenith.

And reattatches for viewing lower, all by the pull of a lever that controls a heavy duty latch.

Very cool Scott. Restoration projects can be so rewarding.
Did you use anything to protect the finish after the sandblasting?

The fellow who had the dome had glued 1" thick black foam rubber to the inside. This was a mess. All dry rotted and nasty. The glue just wouldn't come off so the last big project here is to paint the inside with some of the roll on Rhino Coat truck bed liner stuff. Should work to cover the glue and retard the sound bouncing all over in there. Those of you with domes know, the sound plays with you a bit the way it bounces.

Hi Rob. It's aluminum except the ring is Galvanized. We thought about spraying it with a good primer (and special primer for the Galvanized) and then white or silver paint but it looks pretty classic so we figured we'd see how it holds up as is.
