Powered Ground Board

It's been a while but I've been having computer problems.

With the top of the telescope finished I started concentrating on the powered ground board.

The first step was to use the router to cut a circle for the ground board. I then proceeded to make the 'feet' keeping in mind that I wanted some distance between the ground and the board I made them 65mm thick.
One of the things that I wanted to do different this time around was to use bearings instead of Teflon on Formica (to see the difference) so that was the next step and from the photos you can see that it has turned out quite well. Once installed I finished it of with dust cover squares made out of Kydex that were glued on in place over the bearings.

There are still things to do to the ground board. I got a Powered Ground Board kit from Gary Myers at StellarCat and that will be the next thing to do.
