Those are some real scopes, Alexander. I've got a 16" waiting in the wings to start on, but I've been playing small in the mean-time.
There's a couple of sub $100 4.5" f/8s, the ball one being the "PortaBowl". A 4" f/6 beater scope "Frank the Tank". And a 6" f/5 called "Frankenscope".
All good exercises, but I really need to buckle down and make the practical biggie... - j
"Frankenscope", , that is one seriously stitched up puppy, . Looks like you've used bits and pieces dug up from some telescope graveyard- isn't that a focuser from an old Astroscan?
I've noticed an RKE eyepiece in another one of your scopes- they are really good eyepieces. I've got an approximately 25 year old 28mm RKE, and it works sooooo well in the 17.5" Odessius.
Not from the Astroscan, but another Edmund 6" f/6(?). - Good call!
Top can, end rings, and finder are cut from some orange Celestron with a broken sled focuser (I bought the mirror, he sent the scope). Bearings are legs from an Ikea table.
Gave it to a teacher friend of mine. Had to ad braces connecting the ends of the bearings to where the trusses connect the upper can because the bearings were like giant kangaroo feet, bouncing the scope all around... - j

Hi all, new member here.
Heres an 80mm f15 refractor I built a while ago.
It was supposed to be a quick project using ag pipe but I got totally carried away.
The worst part was all the polishing.
The lens is an 83mm Jaeger (sp?) doublet, all brass and large section aluminium is home cast.
If anyone is interested the full build details can be found here https://www.hobby-machinist.com/thre...fractor.26212/
My latest project is a 12" bino.
Another very long project but its getting closer to the finish if we consider grinding and polishing the two mirrors to be a quick job.
Again the full story is here https://www.hobby-machinist.com/thre...nocular.55688/
I hope to be flexing the mirrors but have a number of questions that I will be asking else where on the forum.
