I had difficulties sleeping must be the astrononomy thing where the sleep is all messed up (or more likely a Sunday Evening/Monday morning before work).

I tossed the encoder into the atz pivot bolt and just kind eyed it up

I dis-asembled the dob baseboard and groundboard and pounded the t-nut into the very bottom placing a board over the to of the t-nut, 3 pounds not a single person woken up

Here is what it looks like from the bottom of the ground board pounded in.

The included a washer and in the instructions it needed to be between the ground board and T-Nut, well the T-Nut has teeth alot larger than this and would have required alot of pounding and I am sure it would have defeated the purpose of the T-Nut, so it ended up being an 'extra part'.

Fliped over the ground board this is what the t-nut with the 4 spike's and threads look like from above

Tossed the old 'teflon?' disks back on, I was afraid without outer support the outer area's would sag, I might replace the existing disk's with the teflon I recieved in the kit alot with 3 strategically placed disks around the sides in the future, but, for now the teflon disk is another 'extra part'

This is the raw hole on the baseboard.

I insert the brass bushing.

I start screwing in the pivot screw

This is the bottom view of the baseboard at the position of the screw in the above photo.

Took a wrench and tightened it all the way down with the set screw facing the open part of the dob base for easy access

.

Set screw inserted

Ground board view, screw sticks thru a bit, if it's a problem I will shorten it

Added the 'lock bolt' with a wrench.

Bolt fully secure.

Test one, turn counter clockwise make sure set screw does not turn

Test two, turn clockwise make sure set screw does not turn

Test three, turn counter clockwise make sure encoder does not turn with set screw tightened

Test four, turn clockwise make sure encoder does not turn with set screw tightened

Extra parts on left, old parts on right, will keep everything

The outer portion of the encoder shaft spins, the inner threaded portion does not. I am going to put a hole in the steel plate and secure with the included encoder hardware, the rest of the shaft will go thru the bolt with the set screw so the encoder shaft spins but, the encoder does not. One person I saw secured the plate on his dob with two rubber bands on going out in either direction allowing a little bit of play in the encoder reducing the stress but, enough tension to return it to it's final accurate resting position. When I spin it I really don't see any movement at all one way or another, I will probably just secure the plate so it does not move at all.

This was Mr. Bubany's old scope, I am going to remove the eyepiece rack (quite honestly this thing is pretty useles) and probably install a project box with switch, external power and maybe an external red LED in the lower right or lower left, I might install a gell/AGM cell holder right next to it (12v/7ah). While the encoder will run just fine for hours on a 9volt and quite a range of voltages and power options I think I will likely end up with having the need for dew supression. I might get a big project box to include a small dew controller circut in the same box with just one power input to the dsc, and dew controller and a few outputs. I will likely place a handle where the 'Duke Skywatcher' is emblazzed, I should ask Ron if he want's those back after I peel them off.
