In this image, I decided to work on the Reflector unit.

This so that the scope connecting piece( for lack of a better name) can seat and be bolted into place. Here is a view of that part.This is also made of 6061 aluminum . The three screws fit into the slots on the top. A small bolt will be added to the pedestal bracket to help with the altitude adjustment and stability.

But for esier transfering of the mount from pedestal to pedestal was made even easier by slotting the top.

Looks like there is some sort of device on the dec plate. What are you using to connect the scope/saddle to the dec shaft? Looking good!

I look forward to seeing the updates you made to your EQ, which I am already aware of. I believe CN members will lover the changes. Especially the modifications to the braking system that work splendidly. I will let you elaborate further.

How will the telescope cradle be joined to the declination axis ? . Look back at the third photo in the thread. You can see a small thick ring with a 1" diameter hole in the center. Here is a close up of that ring. It fits the declination shaft perfectly, and has an allen head screw on its side so that it can be tightened down. I can lock it on the shaft by way of this allen screw. Using my drill press equipped with a 1/3" diameter metal-cutting bit, I bored 3 holes equidistant all around in this ring and in the plate to match .

You'll have to trim that DEC shaft, looks a bit to long, and with all the counter weights in place it will flex quite a bit. You'll probably not detect it visually but thru eyepiece could be noticeable.

As a matter of fact,I will replace that shaft entirely with a new precision 30" x 1" diameter one and two new pillow blocks later in the build. Do you guys recognize this?

Next ,the worm and motor assembly.

Note the six hexagonal spring loaded clutch adjustment allen screws. For this mount to work properly this clutch must provide slow motion in RA movement. The objective is to achieve what Mel Dawson and I like to term " Stop Right There" capability. This means that with all things considered, wherever you point the scope (doesnt matter which scope is up there) that the scope stays on what it is pointed toward. This drive is a marvel in precision mechanical construction and it is one of many of the great works of Mr. Byers.

Re: A 1" Shaft diameter Pillow Block Mount Build [Re: BarabinoSr]       #5723578 - 03/10/13 09:52 AM Edit   Reply   Quote Quick Reply   It's almost sad that most don't see the simplicity, beauty, reliabilty and ease of construction in a pillow block mounting. I find that an industrial "look" is really not all that bad. After all ever see a professional observatory mount that looked like it was purchased out of a catalog?
