Yes…I made another mistake that I had to fix -_-

If you look at the photo in the previous devlog, you’ll notice that the connection between the displacer piston and the crankshaft actually overlap the power piston’s shaft—it moves in front of the connection between the power piston and its crankshaft! This was very hard to model in Onshape.

So I had to improve the linkage so that the power-crankshaft connection moved in the front instead. After a bit of tweaking (and painful double-checking), the linkage seemed alright.

So, I modeled the system in Onshape and it seemed to run well.

Now I have finalized the linkages, making sure that they don’t overlap and run properly, and everything finally seems to check out!

I’ve learned that prototyping, design, and checking my work is very important when it comes to engineering. I should learn to be less careless and spot these mistakes before investing too much time into them!

Although this was frustrating, I’m very happy that I learned that lesson :)
