I'd be interested in this, too. Does the saddle fit far enough onto the shaft so the mounting screws clear those threads used for adding another extension piece? It looks like it might be okay.

The bore hole is flat on the inside. Nothing touches the threads of the bar. The side screw that locks onto the bar fits into the recessed part of the bar extension. The adapter is 1/4" deeper than it needs to be so you can slide it an extra 1/4" if you want it to be flush to the end of the bar. But the lock screw will be on the main surface of the bar instead of the recess. I put a 1/4" thick rubber grommet inside the hole as a stop do that the lock screw fastens to the recessed part upon insertion.

Thanks for sharing this with us. I'm going to give it a try. I don't have a caliper, so I took the best measurement I could. Came out to be 30.2mm. Just placed an order - hopefully this will work out!

PPS: I decided to try an 8" Orion Dovetail with Adjustment Screws attached to a plain 8" dovetail that is attached to my 80mm apo. The plain dovetail will act as a base for the adjustment screws to press against so I can align my 80mm with the main scope.




Please let us know how this works out, Fred. I've been using the shim solution with my LX80 for many months, so I've gotten comfortable with it. But, I'd still like something easier. Another solution mentioned on the Yahoo group was to drill holes in the secondary saddle and insert adjustment screws.

Jerry




Yeah, I thought of that, too, as the metal is pretty soft but I hate doing such mods cause I get only one chance to do it right. It'll be sometime before I can report 'cause I'm recovering from a knee injury with 4 weeks of therapy ahead of me. The adjustable dovetail is only $20, so if anyone is anxious, the worse that could happen is that you'd end up with an extra dovetail with adjustment screws.




Did it. I saw that my Comet Hunter already had an adjustable dovetail with it so all I had to do was adjust that and then align the 80mm's saddle in altitude. Took some time to do it as I had to dismount/remount the Comet Hunter several times to get the dovetail adjustment screws right.
But it works.
