254mm F4.5 Compact Dob
Just started building another new scope. I was very happy with the one I built for Phil Hart so I am now using a 10" F4.5 mirror I bought from 33South a couple of years ago as the basis for another one of very similar design.

Attached images are the 303mm former for the UTA built up from scrap timber and the glue up of the first 2 layers of 1.8mm plywood. A final third layer to go tomorrow night. The UTA will have an ID of about 303mm, an OD of about 315mm and is 385mm long.

Final image is of the 8" F6 I built for Phil. This one should look similar, just a bit on the "plump" side.

Cheers,
