This is an experiment I call “Linear Oscillation – Linear Acceleration” aka LOLA. This was only put together (from PIE components) to bench test some working theories and share some results with those people collaborating with me on the Trammel engine project. It was never expected to actually generate thrust since it is barely half of the necessary construct. This “could” be used (more or less) for thrust generation if there was either a speed differential control added, or another spring-loaded rod set at 180 degrees away from the one used.
This was 2 videos (poor audio…sorry) pasted together to show running after initial setup and then a rolling oscillation test which shows a definite “directional bias” but is not really able to self-propel due to an incomplete build.
I pretty much verified what I wanted to with this setup, so it will most likely not continue as a project of its own…
Thanks for watching!

In this second presentation by Ross Small for APEC, he demonstrates the “linear components” of his machine. This working theory of the use of linear components definitely relates to the Trammel engine and some of its internal components.
Next up, I will be posting a video which was meant to be a private share with associates working with me on Trammel engine technology. The “LOLA” or Linear Actuator & Linear Accelerator was never meant to be a propulsion device. The LOLA was only meant to assist our understanding of over-center linear energy movement.
Thanks for watching

In this presentation by Ross Small for APEC, he talks about “linear components” and the movement of energy in a straight line. This relates directly to the Trammel motor although it is built very differently.
Very soon I will be posting a video which was really only meant for me to re-watch later on and share with associates working with me regarding the Trammel engine. This will be demonstrating an experiment I called “LOLA” for Linear Actuator & Linear Accelerator which was not meant to be a propulsion device but just a hands-on visual aid to assist in understanding the effect of resistance going “over-center” in a fully rotating environment.

Part two of my presentation at the APEC Conference on February 26th, 2022.

Part one of my presentation at the APEC Conference on February 26th, 2022.

The new motor is installed, testing and adjustments has begun. His video shows the Trammel Engine “jumping” slightly, for anyone thinking it is “pushing off” the workbench surface, it doesn’t matter how it has come to rest it still jumps. Even if I rest it on my hand where a 200# mass would impart some pretty strong (finger crushing) weight pushing off from it but there is negligible extra push against my hand…
More to come soon, I hope!!! Thanks for watchingY

Here is a first trial run on wheels for the PIE Mini.
It is awfully heavy for the size of the single rotating weight to move, I used heavy axles and bearings for the wheels since that is what I had.
It would have more visible power if it were not "slowing down" its rotation speed at the wrong moment in rotation and had an extension on the weight for better timing.
Thanks for watching.

The first run of the PIE Mini under its own power. The next step is getting some wheels on it… Or maybe float it on water, air, or something more exotic now that there is a unit that weighs less than 10 pounds!
Thanks for watching!!

This is the second part of the model demonstrator project’s first unit built. I was very surprised how much thrust power was generated with each pulse! I need a motor for it now, so it will run without being held onto. More to come as things progress.
Thanks for watching!

I decided that I need a demonstrator, portable enough to be easily carried into potential investor’s offices. This will also show scalability. This is the first part of that demonstrator project. There there will be more models built once this one is complete and working, and they could eventually be for sale if there is enough interest.
Thanks for watching!

I am preparing to install a much-needed upgrade motor on the Trammel Engine! I just got the motor electrically connected for the first time; this is that first bench test.
Although the frequency of my public videos has slowed, the work continues.
Thanks for watching!

The “PIE X” is now officially getting a name of its own. It is now the “Trammel Engine” which is a mechanical inertial propulsion system.
This series of 2 videos is taken with no rehearsal, no pre-video test runs, and no cuts. The first video shows little to no upward thrust, while the second video shows solid lift until the fuse popped! It repeats and is now undergoing minor internal renovations to prepare it for running at a projected 1000 RPM.

I had the honor and privilege to publicly unveil the PIE X live during the amazing 1 year anniversary APEC conference & this is it. I did have to keep most of the internals hidden (for now), and although the bench setup was not ideal, it does have measurable upward thrust when running (even at these low RPMs). Measured thrust (frame by frame analysis of diagnostic videos made) is .77 lbs. even at these low speeds.
More to come soon, thanks for watching!

I have been asked if everything is all right since I have not posted any video updates since I started the PIE X project. To put the question to rest, I am posting this update which gives almost no detail on the PIE X build but does indeed show that I am still here, still building, and still active. I am hoping to have some functional test videos eventually but the internal workings are still being considered a “trade secret” that I will not share publicly! Thanks for caring, and as always, thanks for watching!

As I was re-routing the chain drive for co-directional (same direction) rotation, I was reminded of the high load point which was causing problems in the beginning due to an uncontrolled speed fluctuation.
I have previously talked about the need for the SDC (Speed Differential Control) and I have also mentioned the reason it was conceived of to begin with. In the earliest of my prototypes the wheels were running with flat pullies and were prone to slippage. If the belt slipped, even a little, there was no thrust so it seemed logical that reversing the slow-down (speeding up) would boost thrust.
The power input to the PIE in this video is at a VERY low setting and it only has one planet weight loading the drive motor making the slowing effect quite easy to see, so I made this short demonstration video.
Thanks for watching!

After the last on road test went poorly, I decided to go back to basics on the PIE 4.8. The Wheels are re-phased to “self-propulsion” and since I know how it acts with 4 gears turning and 4 weights moving, I thought it would be a good idea to see how it will work with just 2 weights total. I know that I misspoke on the video and said 2 gears per wheel, I meant to say 2 gears total.
I did install the 2 weights that are not being used for propulsion onto the wheels, but they are only there to balance the wheels a bit so that it does not shake itself so hard that something breaks.
This is a first step taken toward finding out which forces cancel each other out, and how to prevent the cancelling of forward thrust forces. Things “seem” to be going well with the cancellation of reversion forces, now the forward thrust needs to be made better.
Thanks for watching!

The micro switches on the SDC (Speed Differential Control) circuit were having problems with the roller wheels and levers. Tokio Muramatsu (https://www.youtube.com/user/dftdmt) suggested using a “proximity sensor” instead of the mechanical micro switch, so I decided to try these simple non-contact magnetic switches. I am pleased so far and I will post the results using these on the next road test.
Thanks for watching!

Road Tests Continue
After a short delay, Road Tests Continue! The PIE 4.8 is in the truck and is rephased for hybrid use. The SDC switch broke when one of the actuators came loose and needs to be replaced, but I intend to road test “as is” since there have already been so many delays in getting this completed.
The video shows the vehicle “swaying” side-to-side due to alternate side thrusting, not "sideways thrusting". It will be interesting to see how this affects handling while driving at highway speed…
Thanks for watching!

Self-Propulsion Compilation.
This is a short video of successfully self-propelling Thornson and PIE inertial drives, the video was created for a portion of a presentation given on 6/26/2001 for the APEC conference.

Video Timeline From the Beginning to the PIE 4.8
This is a video Timeline of the PIE project from the first 2 gears through the PIE 4.8, the video was created for a portion of a presentation given on 6/26/2001 for the APEC conference.

The PIE 4.8 is ready for hybrid testing. After showing promising results in its first on road test set, it is time to get it adjusted properly and do some “serious” road testing! This video shows the initial re-phase. It is not adjusted properly yet, and you can see in the video the wheels are cross-thrusting, i.e., the LH wheel is pulling right, and the RH wheel is pulling left. I am also going to attempt to install more SDC actuators to accommodate the new phasing.

I had previously said I did not believe the swing test to be accurate, but there have been a lot of people asking for it. So I decided to go ahead and demonstrate how it passes this swinging test. I am also showing how and why it can fail the test.
Since I am not out to “prove” anything, just demonstrate the machinery I am working on (and with) this actually seemed like a good idea.
Here is the main point I want to make. ANY pulsating drive (mine or any other) will not show good results unless it is synchronized to the time-base set by the swing itself. The longer the swing, the slower the machine has to run otherwise it is just a vibrating mess!
This test had the PIE running VERY sow so that there was only about .5 KG of thrust, but it is a good demonstration of linear thrust either way.
Thanks for watching!

PIE 4.8 Being Fitted Into The Motor Vehicle For On Road Testing
This is a short (noisy & unplanned) video... The PIE 4.8 is ready for final hook ups to the pickup truck it will be tested in. In this video it is sitting directly on the steel bed of the truck running at 53 RPMs giving 106 pulses per minute, and the truck is inside a garage, so it is pretty loud on the video. I just need to make a new rain cover for it and hook up the wires for operating it from the cab (simple on/off for now).

The new frame is complete (I think) and about ready for testing. I may still put a bar across the axles to make it as stable as possible. I am reasonably certain that if it were turned properly on the cart (and fastened to it) the assembly would self-propel. Note the way it pulls the wheels off the ground!
Please excuse my dirty hands, I work for a living and dirt is a constant companion.
Thanks for watching. More to come soon.
