Nice!  
That steel piece should do the trick nicely!

The points of friction at the pivot points are actually not a very big problem because each arm acts as a long ever. This post sort of explains why: [Throwing my hat in the sled modification ring](https://forums.maslowcnc.com/t/throwing-my-hat-in-the-sled-modification-ring/193/595) That is assuming reasonable amount of friction. Those pivot points should move freely but they _don’t_ need to be nearly frictionless.
