I bet if you used a hydraulic press and heated the glued layers while compressing them it would make it alot stronger. Maybe even throw a couple small cross bolts through it to hold it together
If you want to try the steel idea and need a bearing you could use compressed grease impregnated leather as an insert bearing. Some old engines used leather bearings as a short term repair.
looks to me like one of the layers didn't quite have proper adhesion and as physics tends to do, it found the weakest point and separated at the layer, someone suggested in the comments section using a piece of ash or hickory and don't do it layered might work, but for lamination you might have to heat the wood up as you glue it and maybe clamp it tightly to prevent any voids from air bubbles or maybe glue it, clamp it, and put it in a vacuum chamber to make sure there's no hidden air pockets, interesting result, and that thing ran really good until it didn't, i'm impressed it ran at all to be honest, definitely better than the 3D printed counterpart that found a strange failure mode
Plastic PE or POM sheet and birch plywood all can be lasercut then epoxied with 1 hour epoxy, the longer dry time the higher strenght, unless shit changed in the last years.
So first off lets see a Lego connecting rod next.... Second, What I think you should have done and what I was expecting was use a piece of lumber drill a hole in the top for the connecting pin for the piston and at the bottom for the crank. cut the rod out on the band saw and sand down what needed to be. think that would be a better idea than layered wood but that's just my take on things, maybe I'm wrong.
So at least the engine ran for more than a fraction of a second with the wood connecting rod. Kind of funny to be honest. I guess that idea might work for one of those hit/miss engines from decades ago because they didn't run at a high RPM. So...next....take one of your connecting rod wood pieces trace it onto a solid piece of wood, probably like a pine 1x material, or if you have something in hardwood in 1x material try that. If more dad's spent time out in the shop with their boys like you do with John, we'd have a lot better teenagers and young men out there.
I think this format will make you some money for a few videos! Solid wood would be cool to see!
Cool to see people thinking outside the box and trying different ideas
I can’t believe it actually ran lol that was awesome 😂😂
Use solid hickory. No laminate.
Lower compression means ..its ready for a little turbo...😂
I can't believe it ran at all. You can try 4 cross grain 1st, then tighter grain woods. Just screen the oil,as it won't be burned.

I was thinking that the glue would break down after being an oil just a thought thank you for the video
Cool video, try J.B. weld to stick them together .
I really like this series. You should try a forged carbon fiber epoxy rod.

Make one out of hard wood like hickory and make it a single piece of wood instead of layers
Good idea will look into what I can get locally.
Sand cast one out of JB weld. Or fiberglass resin reinforced with metal filings.

Make one out of elm or Willow.
You could use a deer let bone.
I feel a little more torque with those split tip spark plugs .

LOVE just for the fun of it experiments!
Try using bamboo planks and epoxy to laminate them with.
Bunch of people have made the bamboo comment. I am looking into what I can get for options.
Notch the bottom of the cylinder for clearance instead of shaving the rods ends down
You Need A ( Solid ) One Piece Bit Of Hard Wood
the insert would on crank taking the pressure of the rowtation off the wooden rod.
How about combining the layers of wood with layers of the 3D printed material?
Great video. 😂

Wooden/3d printed piston?
try it with a solid block of wood instead of plywood.
Love the goofy stuff (dumb ideas)
You need to a Solid hand wood mahogany I wonder how hard bamboo is. But you don't want to use a plywoods
Bamboo That is a new idea adding that to the list :)
Wood made connection rod 😂
make it out of carbon fiber with a steel bearing insert
I guessed 3 putts.
Yall just be getting but hurt over these comments 😅
put insert in crank end
Explain? How would that have made it better?
3 hp DIESEL IN LAWN TRACTOR GO KART
stupid, like you said....lol
Cross grain like plywood-x|
We did I point that out in video.
LOL!!!!
