Well I pulled the DEC down again.
The only way I could see to fix it was to move the motor closer and thereby getting a deeper engagement with the straight gears.
This worked very well, there is the slightest slop, which may not be further fixable...I had the gears meshed very tight...but I am not pulling it down again today.
Nearly finished the cement pier frame and reinforcing, I will complete it before putting the box, observatory, together.
Got it all figured should be simple.
