I own a wonderful A-P1100GTO mount and I have been pretty successful imaging with this mount. I have a question. What are these two 3/8"-24 panhead bolts used for on both RA and Dec axes gearboxes? They are very useful for me making a very simple bracket to mount QHY PoleMaster as shown in the following link:

peternagy.smugmug.com/Telescopes/PoleMaster-on-A-P1100GTO/

These bolts make my lives a little easier. Now I noticed the latest A-P mounts with new gearboxes no longer have these two pan head bolts for A-P 1100GTO and A-P 1600GTO mounts? Would it be possible to go back to the drawing board and retain drilling and tapping these two holes on all A-P gearboxes for future mounts. They are not just necessarily for QHY PoleMaster but may be useful for other purposes.

Thanks,Peter

I meant 5/16"-24 panhead placeholder screws (not 3/8"). Sorry about the confusion.

That's great news!  I met with the rep at NEAF  who tried to sell me on something that sits in the threads on A-Ps 1100 there with A-Ps permission of course.  I told him no way it has to thread in and he said a lot of guys buy them this way.  I said it's not worth risking the threads nor take the terrible time to tighten their set screw awkwardly in the hole.  As I requested this adapter a long, long time ago with many 1100 owners also following suit, so this is very encouraging.  In case they do not notify those of us who did request these real adapters please keep the group informed of their progress.

Pete nice alternative but you really have to keep that axis positioned so I hope you get one of these too when you move to the new style gear box.

Thanks!

Peter,  They simply prevent dust from entering the gearbox while allowing access to the screws within.  Regards,  George  George WhitneyAstro-Physics, Inc.Phone:  815-282-1513Email:  george@...

Hi George,

I now understand that the two panhead screws are there as placeholders but my last question was what are the two set screws underneath the placeholder screws are for? Are they used for some kind of adjustments for internal components of the gearbox? Are the set screws something that customers should never mess with?

Thanks,Peter

Peter,  They are simply placeholder screws.   However, they need to be shallow and not hit the screws below.

Peter,  They hold the springs that provide the pressure for the worm / worm wheel meshing process.  Regards,  George  George WhitneyAstro-Physics, Inc.Phone:  815-282-1513Email:  george@...
