I'm very qurious how one of these well built pillow block mounts would stand against one of those comercial monsters in terms of precision for imaging ? Of course with a drive like this Byers.

This mount can be made to even better tolerances than this and has great potential for very good precision astronomical applications.

See how all this is going to look right uptown? What's nice about pillow block mounts are the real basic beef parts are simple and quick to put together. Plus they have numerous places where you can add "stuff" without dealing with curved surfaces to tap into etc. Then when you coat them with a nice crinkle finish they do indeed look quite "industrial" and operate like it too! Yeah they aren't meant to be portable grab 'n goes they are for semi and permanent setups. It'll look first class Gary. Guess what Gary? Something tells me you aren't going to stop at one unit or 1" for that matter. I see more in your future. Mike
I am not familiar with these bearings; but am curious as to how one handles the axial thrust loads?
A pretty interesting thread, learning lots. Thanks for sharing. Dave O

How much load bearing put on this unit depends entirely on the weight of the scope that will be used upon it. This was built to handle an 8" f/6 Newtonian, plus three others all lighter than the first one. These pillow blocks are reasonably priced, light industrial strength quality. I believe that this unit can carry up to a short 10" newt with the proper counter weights attached well. It is very tight no loose parts and well balanced.Another thing; the 1-inch shaft can accept barbell weights with a 1" center hole. If you're considering one of these, I recommend using PRECISION steel shafts for RA and Dec. with no shorter than 12" length for the RA axis and no longer than 30" for the declination axis. My RA axis is too long and will be shortened considerably to 1.5" beyond the clock drive. You can have fun building one like this, and as I said before, it not that expensive. Gary

What's next ? The refractor mode tests using the 4.5" f/10 Jaegers and 5-inch f/9 Apogee scopes to be conducted to night weather permitting. And the connection of the RA Byers Drive as well in a few days . Presently I'm awaiting the arrival of a small aluminum box , and also got a power cord for the drive converting one I already had from an old pc. This box will be screwed to the underside of the RA axis plate to help protect the drive's electrical connections from exposure to excessive moisture so common to this area .So the work on the build continues! Some views of the system as set up last night with the scope pointed at Jupiter.
