Reading that the 8020 linear bearings are ok for some but not all, has me thinking of ways of combining the simple skate-brearing assembly idea with 8020 components.

First drawing has the rod fully surrounded, which is going to make tuning and assembly a pain.

Second drawing requires the ability to 'rip' off the corner. It doesn't need to be an accurate cut, so maybe a jig saw wouldn't be too rough.

I'm still getting ramped up and planning my first machine. MDF or 8020 it's going to take me a while to commit to a design. (And I need a real drafting program).

(my 2nd post. Woo hoo.. be easy on me)

Examples use
40 Series 8080 extrusion
25mm rod
15mm bearings

I like this idea better than just using regular angle aluminum. Have any pics of it put together?

Have you done any more work on this idea?

How do you adjust it to tighten it up on the shaft?
