We also made the 1.5 inch by .250 inch rods that are drilled and tapped for 4-40 screws on both ends... Here's slitting the 10-32 adjusting screws.

For as simple as it looks, I would never have guessed that it would take the better part of 3+ days to get to this point...Those one off setup are a time Killer Hope You enjoy the progress... Best Regards, Preston ps, we will most likely be making another Primary Baffle Tube without the wrinkles at some point Edited by PrestonE (11/23/08 05:09 PM) Post Extras:       rwiederrich Goldfinger Reged: 11/17/05 Loc: Always Dark skies of Belfair W...

[Re: Mert]       #2768231 - 11/24/08 04:50 PM Edit   Reply   Quote Quick Reply   Rob and Mert thanks for you always kind words and support... Things are progressing...I think that I solved my design issue with being able to adjust the Secondary Baffle last night while DREAMING me Please No really and I've started work to that end today...pics tomorrow, but I had really been dreading this one and the design is so simple I cannot believe that I did not think of it earlier... Hopefully the aluminum order comes today for the material needed for the Squaring Plate/Field Rotator...and hopefully the team member that has the Paramount VersaPlate got it shipped to me today... Best Regards, Preston ps...also got an idea for a Primary Mirror Cover that will close over the mirror like flower peadles when the scope is not in use now if I can only find some more time...

[Re: PrestonE]       #2779039 - 11/30/08 08:18 PM Edit   Reply   Quote Quick Reply   Well the Thanksgiving weekend gave me at least 36 hours of machine time on things...got the Primary Baffle drilled for the Collimation Jig...now need to redo the Baffle to rid us of the wrinkles... Thus, had to fill in the groves in the mandral from sawing the Baffles to lenght and then drilling the mounting holes...there has to be a better way Moved on to the Field Rotator/Squaring Back and have progressed nicely without any errors When you see the drilling pattern you'll understand my happyness.... Pics will be posted tomorrow...I've been going from about 8am to 5pm for the past 4 days and couldn't think about sizing pics and then posting... Until Tomorrow, Best Regards, Preston Post Extras:       PrestonE Pooh-Bah Reged: 04/29/05 Loc: San Miguel de Allende,Mexico Re: 20 inch RC Robotic Build...a TEAM Effort....

The mind does strange things some times...like assuming that the radial distance and the offset from that radial to a point to the side would be where you would spot the event.... No, we should have rotated the Rotary table 12 degees instead of doing the offset... More tomorrow...and I promise to update more often...

These will allow us to adjust the Primary Baffle to the secondary baffle.

Here we have finished up all of the lightening pockets and the ID through hole and are working on the outer cut through. Thus you can see the outline is just a triangle with the tips rounded.

Here we are turning the OD of the Rotator Ring after havinb bored the ID out to clean up the rougher edges.

Here we are boring the central hole.
