Gas-Powered Pogo Stick Rammer [Restoration]
Welcome to the greatest thing you are going to see for a long time. This restoration is on a Barco BR-5 Rammer made by the Barco Mfg. Co.. This marvel of insane engineering is technically a 2-stroke motor with no rotation and two pistons. You read that right. The top piston sucks in air and fuel through the carburetor on the upstroke and that mixture ignites when the piston nears the top and trips the magneto, creating a spark at the spark plug. Springs pull the top piston up and you push the top piston back down. The explosion in the cylinder now pushes the lower piston out from the bottom of the machine. The lower piston just so happens to have large magnesium foot (why magnesium? I have no idea) attached to it, so the whole machine jumps in the air with each explosion. When gravity eventually takes over, the 200lb machine slams into the ground, completing its job an a tamper. Its job might be over, but the horror has just begun as the momentum of the top top piston slamming back down to the ground eventually leads the springs to pull it back up, beginning the cycle all over again. This means that the tool can actually keep running without human input, slowly stomping down the street, crushing everything in its path, and the only way to stop it is to grab the handle while in motion and hold it up so the top piston can no longer trip the magneto. That is the only off switch.
Other than the horror, it's insanely fun to use and is great at children's birthday parties and cideries.
The most challenging part was machining new valves to some unknown specification.
The amount of broken, seized, and missing parts made this one of the most difficult restorations so far, with the lack of a manual also contributing to that. If you ever see a manual for this tool, please contact me at handtoolrescue@gmail.com

Please contact me at handtoolrescue@gmail.com if you ever come across a manual for this machine. Thank you and don't die!
I was excited to see your most recent addition to your "Fuel-Powered Tools" playlist. (Not this one.)
ohhh fuck the perfect machine if you have anoying neighbors in the apt bellow you
FYI, most "Class D" fire extinguishers are just a bucket of sand.
TIL you have commentary in the closed captioned stream. Now I need to rewatch a bunch of videos 😂
The end of the video is so funny and satisfactory, the giant boy and his toy. One more time, congratulations!
Ah, those halcyon days before OSHA intensified. When manly men did manly things in a manly way with manly contrivances.
HAHAHAHAHAHAHAHAHAHAHAHA. Man, I needed this laugh today – thank you! Seeing that thing fire for the first time is pure physical comedy gold.
This is amazing😂 I want one so bad!
See music video from Captain Sensible Wot 1983 😀
you did an awesome job
What a neat little machine!
37:54 caught me off guard. Love your humor sir 🙂
this is the first time i've heard of one of these
AKA hopping machine
This machine is completely unhinged! 😂
Loved it. Now attach a chair to the top and ride it.
Seriously though, you looked like you were having a blast ruining your grass.
That looks like one leg of Wallace and Gromit's 'the wrong trousers' and I bet the worms under that patch of grass have got some mega headaches now. Love your videos.
I watched the whole amazing resto but when that thing just goes with no operator… Holy fuck
If my guess is correct, this machine is made for compacting the soil in order to lay the foundation of a building, right???
Ну мужик ти самий крутий реставратор якого я знаю , молодець 👍👍👍
This thing has got to be one of the most idiotic yet awesome machines I've ever seen.
