Hi George,

I’m closer to N Yorks so I cut the 54 degree curve.  If you are nearer the south of W Yorks you may wish to go with the 52 degree curve.  Once I printed out the curve, you just trace it onto the aluminium and make a series of straight cuts (marked red) and then file the waste away - aluminium is relatively easy to work with. The aluminium is so thin that you just cut it at right angles.

this eBay link should help:

You need two rectangles of 200mm x 100mm.  If you buy the 200mm x 200mm sheet of 4mm aluminium then you can cut it in half.

I wish you luck. My biggest problem was finding the names for the components and where to buy them, like pillow bearings,  but if you search google long enough anything is possible.

Hi John

what angle did you cut the aluminium if you can remember I can source the other bits n bobs but the aluminium sections are stumping me angle wise

Thanks

Hi George, and welcome to SGL.

I think you may need a Celestial guidebook. This one will help you find lots of interesting objects by "Star Hopping."

Evening folks from a cloudy west yorkshire just thought I would say hello I currently have a skywatcher 200p recently fitted a telrad as I'm terrible at finding stuff and thought it would help however I'm clearly just incompetent 😂 been thinking over making an eq platform but I also lack any form of DIY skills 🙄

Thanks

George

Loving this as I have zero technical knowledge and minimal d.i.y skills but this would be ideal for my 8" dob
