All I have to say is why didn’t I do this YEARS ago! I just gave a 6 year scope that hasn’t really been used in say well over 4 years except for outreach and occasionally at home. A long time ago I added from Tony C. at Astronomy-Shopper (LINK) his Scope Grips. They were a MAJOR improvement in the altitude system for my Orion XT10. I could loosen or tighten the knobs to increase or decrease tension depending on my eyepiece. To be honest, I found a position for the eyepieces I used and left it there for my observing session. I may have to make one adjustment just to tighten later that night. I highly recommend them if you have a stock Orion XT dob. I also got Tony’s Scope Totes (FYI, I don’t get anything from Tony I am just sharing info) which you can see both in my video and at this LINK. There are cheaper alternatives like the Strap Handle LINK or over at Home Depot (also Lowes) is the Velcro Hand Strap Handle LINK. I like that the Astronomy Shoppe Scope Totes fit my OTA and they make it so much easier to life. I find that after a year of losing 80lbs and working out four times a week, that the 10″ is not heavy to lift at all. It is just awkward and the Scope Totes make it easier to life.
Now the only real issue I have never liked on my Orion XT10 are the azimuth motions. I didn’t mind the stiction I guess when I didn’t know any better, but my 14″, 17.5″ and 24″ have made me realize and adore buttery smooth motions. I have read before about adding a Lazy Susan bearing to the XT10 LINK and I finally after an evening of outreach about 2 weeks ago, decided to give it a try. The worst thing that could happen was I had to remove the Lazy Susan, have four holes in the bottom of the base board and return to the current method.
Well, I ordered a 12″ Lazy Susan bearing since I could not find one locally and it arrived earlier this week. I went to Lowes today and got both some #8 screws in the 1/2″ size to mount the Lazy Susan on to my base board. I had extra carpet so I cut about 1″x1″ strips and flayed off any carpet that might want to come off (so they don’t go into the bearings and mess this up) and used black electrical tape to secure them. I am sure I will have to adjust that later but that is fine.
To get started I took the base apart, something I have done quite often trying to improve the motions in azimuth and then took the bottom base (some put the Lazy Susan coming down on top of the base; I went this way as I was thinking that if I had it come down and facing down, it might be easier to get dirt into it but on re-thinking it, it shouldn’t. I did it this way as it made sense to me as if I was actually installing a Lazy Susan in my wife’s cabinets. Anyway I WISH, I really WISH I had filmed me measuring out my two lines, each intersecting the middle of the hole in the board. With those lines drawn, I measured the inside diameter of the Lazy Susan, the open part, and then measured using a caliber and a compass the exact location where the Lazy Susan should be. I then used a punch to make a slight hole in the center of where the Lazy Susan would attach, removed the Lazy Susan to my bench to protect it from dust and drilled, using a bit smaller then the diameter of the screws I was using (#8 1/2 inch) to start the screw. I then changed the bit out, put in my bit into the drill, laid the Lazy Susan back on the base, lined it up perfectly and screwed down the screws securing the Lazy Susan! My next step was to put the carpet down to act as breaks, (I put one down behind each teflon pad, one isn’t in place yet in the picture) which they do nicely and as you can see in the two pictures.
