Came across a Sky Watcher 250 p classic. OTA only. No base. How hard is it to make a good Dobsonian base? What other options are there for mounting a 10" newt?

Hello Chardo, 

 

This would be better posted in Equipment->ATM Optics and do it yourself forum.

 

I was able to buy a new tube from a wholesaler in Indiana, it was an excellent telescope.

I started thinking about building a base, then someone on CN had one for sale at a great price.

And at this point in my life, I have more money than time, so I went that route.

 

Building a good base is a subjective thing.   A lot will depend upon how good you think good is.

Do you have wood working experience?  You will probably need a saber saw, and a drill.  A router

would help cut a very nice circle, but is not necessary.  Of course dob bases don't need to be circles.

 

I don't think a 10 inch dob can be mounted any other way, unless you are willing to spend a small fortune.

 

And also thinking out of the box, any way you can mount the tube so it can be turned in azimuth 360, and elevation 90 will work.

Thanks Apollo and Voyage ,
I have woodworking skills. I've been a carpenter for more years than I care to admit.
I hope I can find some good ideas for what to use and what to avoid in make a good function so base.
Th a is for the links.

I'm by no means a web guru, you can just start a new thread, and cut and paste from this one.

Maybe if you ask  the site moderator they can move this thread.

If you are a carpenter, I think you will have no problems.
