Welcome!

Ford hasn't stopped production of IC engines. They've stopped research and design on IC engines. Their current crop of engine designs is their last (unless market forces push otherwise). I didn't watch the entire video, but I did watch the animations. Forget about this concept being...

The TD is from '52.

Now some pictures of the final design and the obligatory video of the engine running:

I've started a different thread with the plans for this engine. You can obtain the design files for this thing here: https://www.homemodelenginemachinist.com/threads/four-square-engine-plans.33841/#post-372431

And finally the 3D cad file in Step format.

Now the individual part drawings:

This is a continuation of the "Un-Named Engine" thread. I've since actually named this thing "Four Square". As promised, here's the plans. I highly suggest you read up on the Un-Named Engine thread. This design requires significant air pressure to run because of the engine geometry. It...

Here's a cross section of the engine at its most advantageous torque. As you can see from the free body diagram, the the torque "arm" (L) is only 0.066". So the torque applied to the crankshaft from each piston is: T = L * F T = L * Press * A T = L * P * pi*r^2 T = 0.066 * 55 * 3.14 * .313^2...

I removed all the pistons and cut in an o-ring groove. Then I reassembled the engine with all four cylinders, two camshafts, and eight eccentric cams. I now know that elimination of friction is more important than having a sealed engine. I was able to get it run down to about 55-60 psi, but...

You realize, compared to many in this hobby, I suck at this. Right?!?! (BTW: I do understand you're describing a Wankel engine.) An idea that's been floating in my mind for some years: I was at a antique farm equipment show and saw this hay baler with the ram reciprocating movement run by a...

Currently there's a significant amount of leakage because at this time nothing is sealed. I can adjust the admission and exhaust timing via the adjustment screws on the valve stems. What I cannot do with this design is adjust admission and exhaust dwell which is set. (i.e. I can move the...

I have two the engine running on compressed air on two of the four cylinders. As Steamchick recognized, internal drag appears quite high because I require fairly high pressure ~70 psi to make this thing run on the two cylinders. I hope to lower this pressure with the addition of pistons three...

Small world hits again.... ...Ved.

I've designed and posted several engine designs here on this forum: https://www.homemodelenginemachinist.com/threads/swashplate-engine.33125/ The plans for this engine didn't really work out. I highly recommend you read the build log before trying the Rotary Engine...

The end of civility in political discussions occurred in lockstep with the growth of social media. People are much less restrained when there's no repercussions (e.g actual threat of bodily harm, or even being their point of view just challenged) in the realm of typing your opinion on a...

This link is to how I made my aluminum foundry from an old propane tank: https://www.instructables.com/Aluminum-Foundry-1/ This video is the entire creation of a flywheel for one of my steam engines:

I gotta keep that one in mind for a future project. Also, nice clean castings!

I'm guessing it uses bog-standard CNC G-code. It's a dedicated language that;s old, cryptic, and very simple. It's possible to program with a text editor, but soft CAM software is the way to go. ...Ved.

When I had my home built CNC router I did some engraving in aluminum with it. As always, the answer revolves around "It Depends." I'm guessing go with very light cuts. The more rigid the machine the better. ...Ved.
