I have had this telescope for 2 month and already feeling the urge to make it a permanent decoration of the landscape.

Inspired by @oldmansky I bought the brake rotor to see if it fits the mount

Wow it does!

80mm from center to wedge hole set is a perfect fit for the 9" rotor, 114mm radius.

Surprisingly metric for a US made telescope!

I'll fix the smaller circle of the brake rotor to the pier @telesonic recommended that I go to farming irrigation supply, with a bit of luck I'll get cheap 6" pipes and flanges. Steel might turn into a magnet but I think there is an old way to demagnetize by banging on it with a hammer.

 

Now how do you think I can put together the brake pad and the pier?

Nice! That should work, I'd think. No ideas as to how to attach the pipe to the brake rotor... you may have to get creative here.

 

As far as the steel being magnetic, I wouldn't worry about it - it shouldn't interfere with the mount at all, I believe. In fact, once you glue a small disc magnet to the back of your HC box... then the pier becomes a great place to stick controllers on. grin.gif

 

Best of luck on your project, I'll try to remember to keep an eye on this one. 

 

Cheers, 

Temp

Finally I found a welder that I can use. And I visited the steel shop to buy some scrap metal to train on. I already hurt myself on some shrapnel while moving the heavy pieces so I am doing something right.

A fellow on Stargazer's Lounge made an adjustable pier. Davey-T's the name.

He uses square tubes to the telescope, angle irons to the ground, thick PTFE in-between and a linear actuator inside.

Hello,

 

I have the same telescope and the same issue. Do you know the details of the rotor make/model etc.?

 

Thank you very much.
