Dunno if anyone has bothered to make their own guidescope rings before but it's about as simple as it gets (not much cheaper than bought ones though).
I picked up a Tasco refractor for $10 (score!) during the week and being the impatient overgrown child that I am I decided to make some rather than wait for them to get shipped.
The Tasco has an outside daimeter of 63mm so I started with some 100mm PVC drain pipe fittings...
As someone has borrowed my Tap set and not returned it I found a drill bit slightly smaller than the bolt shank and drilled 3 evenly spaced holes for the adjustment bolts and one central hole for the mount. I did this by eye because this is just the prototype, the next one I'll measure it properly.
I know those bolts are too long, I bought the longest ones in the shop for the prototype, the final version will look much neater. As a finishing touch I added some dome nuts to the bolts to protect the tube from the threads.
Thanks Cam, they won't be putting anyone out of business any time soon they look better in the dark
I still can't seem to work out how to get my pictures to show up
I just spent half an hour aligning my main scope, tasco and the red-dot only to catch the counter-weight on the sleeve of my jacket and bump them all off line again
) M5 bolts for the adjusters.
they look better in the dark 
Sweet , less than an hour and probably less than $30 all up , good on ya LAW .
