[Coogrrr]

I am not using "gas" pipe for my rails as I went with solid steel and linear bearing from vxb see previous post. I needed a way to secure proper hieght across the length of X and Y and hated the thought of drilling and taping round stock so I came up with this concept.

The aluminum is 1/8th or 1/4th and the part touching the rail will be slightly concave to mate to the 20mm rail. The part on the frame is bolted down but sloted for adjustment. Hieght adjustment is in the form of shims if need be but I plan to cut these to the exact hieght of the pillow blocks on the ends. The blue arrow in the last pic points to the open end of the linear bearing and how it clears the support bracket.

What ya think? will work wont work?
