Well I just deleted the site. It makes sense...our Quad is not a true replica but close enough. Too bad, our 3D model of the assembly looks pretty cool.

I think you are right Steve...even though our plans are significantly different. What happens if someone builds a Quadricycle replica, and somebody else measures it and creates plans, and then builds their own? Maybe one guy bought the plans and built a Quad...then loses the plans. His buddy...

Besides building a Ford Quadricycle replica we will also be revising our CAD drawings to reflect the changes we have made throughout the build. Once that is done we will most likely provide PDF versions of the complete set of plans. Again, the correct plans can be purchased from Dave Dunlavy...

Ya you have to have SolidWorks to open those files....SolidWorks has a free Viewer on their website which I think will let you view the drawings and print them.

Thanks for sharing Steve...looks awesome.

That must be awesome to see them driving around. The Ford museum is on my bucket list but it is so far away...one day.

So we have great compression in one cylinder but almost nothing in the other. Most of the air is leaking past the intake valve. So I decided to re-design the intake valves and seats to make them easier to seal...more to come. We completely over-hauled the front suspension, fixed a bent...

Great job! It came out awesome!

Awesome engine! I like the little water tank (or fuel)...very cool.

Try this one... https://youtu.be/VRgRPA4z2r8

I hope this works. https://www.facebook.com/100010615121056/videos/294242807606221/ The 2 new valves worked....we got a ton of compression...engine ran great on a few squirts of starter fluid. Very exciting...however running on fuel drip may be the next big hurdle. BUT...the engine runs!

Thanks Steve...I ended up making 2 exhaust valves...and re-touched the seats just slightly to about .100in wide seat. I made the valves with a 1/4-28 thread on the ends...I'm going to make a spring retainer that I can adjust spring tension with. The valves sit really good in the new...

Thanks Steve...I was going to "run the rings in" by belting the flywheel to the lathe on low speed. Turning it over by hand is killing my back. But I can hear and feel a ton of air coming out of the exhaust pipe during a compression stroke. All 4 valves are leaking air. I purchased the valves...

OK...I rebuilt the piston, rings, and connecting rods using the new wrist pins and new connecting rod bushings. I installed the piston assemblies into each cylinder using a pipe clamp, flat head screwdriver, and lots of patience. I had the exhaust heads off to check for clearances and everything...

This caught my eye...looking forward to seeing it through.

Long story short...we honed the cylinders to match a new set of Pistons. I never really liked the aluminum pistons and the skinny rings. I wanted to make custom pistons with thicker rings all out of cast iron. I thought of an old Maytag engine I have and the rough size of the pistons...I double...

I love the beer can and the color!!!

I never expected to back back in this thread but here goes. My Ford plumbing engine runs o.k. but has always had carb issues which prevents it from running long periods of time. I finally decided to switch over to a vapor carb and so far great success. I watched a couple YouTube videos and a...

My half-scale Quadricycle cylinders were never bored and the engine runs great with lots of compression. I only honed them but I am also using an O-ring on each piston. Maybe this works for the smaller engine but not full size? I could use 1-ring and 1-high temp O-ring and see if that helps...

Yes Kyle...building it at NEIT. Room S212.
