Originally posted by Ben_Edict I bought one of those – they are made of black plastic! When you use the thumb screw, to lock the lens down, the whole ring deforms massively. Not exactly, what I expected! On the other hand, the construction is so easy, I will make a similar one on the lathe myself... from Aluminum, of course.

Ben, if you are going to make one, and not just because I like the one I made, you should consider copying what I have done.
It provides positive support of the lens if you want to tip the tripod head at a right angle. The one with a thumb screw won't do this.
I formed the ring using a spray paint can. it was just the right size to get the curve I wanted. The ring needs to go just past the cemter of the lens to hold when at 90 degrees. I avoided a full ring because i saw no need.
The ring is lined with leather attached with contact cement, as is the pad under the camera. This prevents scratches.
All aluminium was available at home depot. I used 1/8 inch by 1 inch for the long strut (2 pieces laminated together with counter sunk rivits and epoxy) and 1/8 inch by 1/2 inch for the ring.
The ring fit's around the lens at the focusing distance scale, (another reason not to use a full ring it will obscure the focusing scale).
I also, for the second one I made, fabricated and perminantly attached a foot that is accepted by the Manfrotto tripod head that is on both my tripods. SInce this is a tripod mount, I saw no need to have a detachable foot for my tripod.
