Very interesting. One thing though, is there a fuel cut off on non-powered revolutions? I would think there must be, otherwise, there would be no point in a hit n miss engine.

Can you provide autocad file please

With your cam for the breaker points on the main shaft doesn't it also spark at the top of the exhaust stroke as well as the power stroke?

Can you not set your table at the correct angle

hey sr dumb question how can find these tool?

How are you getting the diameter for the pink circles?

definitely not the slowest

Thats amazing, a wonderful piece of engineering

Your system is i available on the market a rider asked me . I made my own too but don5t know the kit is for market sale

Wow.. that engine is a work of art!

Do you have any plans available?

Bonjour monsieur , Je suis en France et je voudrais savoir si vous vendez des moteurs et si vous pouvez l’expédier? Vous faites de belles vidéos. Merci gratitude 👍🤞✌️Michaël

Great video. You need to know basic engine operation to understand his explanation which is fine.

I heard my first hit-n-miss engine 40-odd years ago on vacation on the Portugese island of Madeira: I thought something was wrong with the engine of a little fishing boat that was putt-putt-putting its way out to sea. Turns out, it was working as expected. Thanks for this explanation. I wish I'd had a shop teacher like this back in the day.

Very nice engine

I'm sure he knows his stuff, but that explanation was so utterly painful to listen to.

Very clear explanation, excellent demonstration👍🏻

Great instruction with only one criticism. Everyone who wants to know how hit or miss works already knows how four cycle works.

To modernize this, we need injection version. Better fuel economy and less pollution.

Beautiful machine. Thank you.

What a thing of beauty and a joy forever. I thought this was 3d printed.

'Suck, squeeze, bang, blow'.

I do like it. In fact I like both the can crusher and the engine. Many thanks.

Got me a 10 set of 1/4" HSS blanks so now it is time to hit the garage and grinder. thanks for this!

Thanks for the great explanation

Thanks for sharing!

what does it mean about "rotated radial and tooth curve for proper backlash?", like how to do it in autocad?

What about cooling? I would think if you put this engine under a good load, it would overheat.

I saw a video this morning of a hit and miss 2 stroke on the Mustie1 YT channel. When he slowed it down by putting on a glove and pushing on the flywheel, the number of firings increased. But yours doesn't seem to do that or the load is so minimal it just doesn't have the effect. Thanks for the tutorial and explanation. It makes perfect sense.

That was super cool

Reeealy thought that would have ben alot faster😂

I was never that interested in these engines until I found this video. You did a great job of explaining their operation.

love it thank you

I inherited one from my grandfather and I would like to know what I need new to get this thing started again? I can send pics or video of my hit and miss. Your video is awesome but I have some questions that maybe you can help me figure out.

Mega Awesome. Thank you. I Been repairing cars for 47 years, but i find things of this nature the most interesting.

You need oil in the gas if yours doesn't have a drip oiler!

Very much a Rube Goldberg useless machine.

That is a joy to watch. We as a species are so amazing at times with the materials we have been gifted with here on planet Earth. Great post, sir!

Love it!! I want to build a larger more modern (slightly modern) version, a two cylinder, opposed piston, with 10"-12" stroke, and 6"-8" bore, make the cylinders from steel pipe, and steel plate, I'd really like to make it a oil burner, either way, maybe it can be ran off oil vapor, make a hot pot carburator, that uses a flame under what is basically a pressure cooker pot, and a small copper coil tubing to drop the temperature below the ignition point . So it doesn't ignite when it hits the airing the venturi of the carb, the throttle changes the oil drip rate slightly, but mostly and opens a valve allowing more fuel out the coil of 3/16" tubing, and a throttle blades probably made from a 24 mm scooter carb, or similar lawnmower carb, with the tube epoxied into the carb venturi, so if could be used for natural gas/propane also the hot vapor being est, 50°-70°F below tge ignition temperature mixing with air entering the cylinder, with a pair of sparkplugs per cylinder, with .060"gap and two coils firing twice per ignition cycle, with a 50-60 kv coil per plug, with a high current , high voltage spark to ignite the oil vapor that should be 150°f roughly when it enters the engine, The pistons cast using old pistons from car engines, the molds made from foam, cast using the list foam method. plaster and sand, the foam piston being made est. 1/2" larger, to account for shrinkage. Use parts from modern engines where possible. Model the pistons after a diesel engine. With the combustion chamber in the piston approximately 80% anyway. Because the bore is so large, the large quench pads, and shapes to induce swirl to promote an effective combustion, the oil rings made from iron pipe cast then fired and machined into shape surface ground to thickness, use a spiring in the ring land stretched around and connected to it's self to space the rings from Each other , with a pair compression ring , top ring 3/16"- 1/4". From the top, the head cast from aluminum, with the water jackets being cross drilled, and cast in, uding plaster and sand, use large valves from a big block Chevy, or Chrysler engine, 1.880" exhaust, and 2.225" intake, opening to 1.000" - 1.200"+/- it doesn't require alot of seat pressure or open pressure, at less than 1500 rpm, weld and machine a crank, from steel bar, 2"-3" diameter, with 4" x .500" thick, use roller wheel bearings for crank main bearing if possible, and a engine main bearings for rod bearings, possibly from a diesel truck engine, in the near 3" range, or a rod bearing, if one is available in that size, use a oil pump to spray the rollers, and feed the rod bearings, through the crank, also the piston pin, fed oil thru a 3/16" - 1/4" braised in steel tube, feeding oil, also feeding the oil ring land, spraying into the 1/8" holes in the piston skirt, the top side to lube the bore, with an overhead cam, possibly using a lawn mower or motorcycle cam with 2.5:1 rockers, with springs only 25psi seat 50-60 nose pressure, possibly use a screw in plug to lower the compression ratio, if the compression ignition doesn't work, (the complex air blast injection system I have an idea for) the injection working like a cross between a paint sprayer and a carburator, spraying oil through tiny holes into a venturi, through another set of tiny holes, using near 30 bar air pressure , lvhp paint sprayer basically, spray the fuel into a 1/16"-1/8" tube in the injectors, using a 1.5"-2" piston to put a air burst through the injector, as the fuel is being injected into the tube, about 50 cc of air at roughly 30bar, a venturi injection may be possible , just spray air through the tube with fuel , in an outside tube, using basically a annular discharge booster from a carburator, blast a 14.5 psi x 30+/- = 380 psi+/-,, air a piston and cylinder filled with the compressed air, then the full volume is used at full throttle. To reduce the throttle, some means to reduce the volume of air, not pressure. Giving an alternative path to refuse fuel and volume of air to throttle the engine. With the ability to go from zero, to 100 % maybe a simple bypass with a spring loaded check valve. And possibly feed the high pressure bypass air into the low pressure air tank , Being multiple stages, multiple compressors,a compressor compressing 120-150 psi air, to raise it another 100+ psi , using a AC compressor, with filters to remove water and oil, dust, and a cotton gauze oiled filter first, with a carbon filter between stages , to remove oil introduced by the compressors, single compressor from a automotive ac system will most likely, reach the pressure, I'm looking for about 150 psi above the engines cranking pressure, so there is plenty of pressure to atomize the oil as it's injected into the engine , with around 22:1 compression! It's likely not going to make a lot of HP, 40 would probably be possible, and it should make a fair amount of TQ. I want it to be used as a DC generator, producing 600 amps at 32 volts, plus, less than 20 kw with losses, it's probably going to require. 25-30 kw of output from the engine, 22hp should do it, if it can do that at 600rpm , with twin opposed cylinders , with Soo much displacement, even if it's running on gas with 8:1 compression it should make enough power to suit it's purpose, it may need to spin 800-900 RPM, that being it's sustainable peak apparently, maybe 1000-1200 definitely, a 12" stroke eq, a lot of piston speed, it's just a matter of finding the scrap to put it together, and the ability to machine the parts!!, Sorry to ramble a stray!! ✌️

The can crusher on the wall of my garage gets the job done in a couple minutes and runs on a little bit of elbow grease, but I would rather it take all day and have fun playig with an engine like that. Thanks!

Lovely engine, and thanks for the explanation. Fascinating look into early 1900s technology. Bit of a Heath Robinson way to crush cans, but that just makes it cooler!

That thing is pretty adorable👍

Brilliant! Love this idea

I was always fascinated by hit n miss engines, my grandfather used to use one to power a corn grindin machine . That one was as old as my grandfather, both were " made " in 1926.

More correctly, it’s a 4 stroke cycle, not a 4 cycle.

So cool! Do you sell the plans for that hit&miss? How about some info on that radial engine in the background?

How cute.

I need to remember the approach with the pins.

Even got the crusher set up on cams I bet this shop teacher was a bad dude when he was a teenager We definitely need more of these kind of teachers They should be the highest paid of all professions

Hey, that's pretty neat, thanks!
