I experimented on the linkages for the beta engine and found a way for the displacer and power pistons to not overlap. I did this by:

• simulating different linkage lengths in MotionGen
• using a rotating crank and a slotted link.

Unfortunately, while one problem was solved, another problem appeared: the linkages were overlapping now!

If you look closely, the areas connecting the pistons to the linkages overlap. Obviously this is a big issue that I will have to solve.

So, now I have two goals:

1. To have the power and displacer pistons not overlap
2. To have the linkages not overlap, either. (How many times have I said “overlap” in this devlog?)

I plan to do this by examining the positions of the pistons when they are at their most extremes (when the displacer is at the left-most and when the power piston is at the right-most).

Hopefully this gets solved by today!
