Default Parallel Motion Linkage...

I know walking beam design is pretty straightforward but recently I worked up a cad drawing to lay out the hole positions and and details required to incorporate James Watt's 4-bar linkage.

The image shown is sized for a 1" stroke so scaling up/down should be pretty simple. I show the linkage on both ends, but most times only one end would have the links. The site below has all the formulas I used.


I figured many here might want a copy.
