It does have six buttons

A rather alien looking relative of the sea star.

@@actionpls. rubber squares or cement pavers

They are not very cheap indeed, but they are worth it in my opinion. As long as there are no sharp stones etc. under the tarp you'll be fine. Have fun with your swimming pool!

@@TheDenyingDutchman Would I still need pavers if the feet rest on the foam?

@@scupking Yes. The feet need support, so yes.

Then it stops working.

It floats, it uses a propeller to submerge.

Boats made in India are of much better quality indeed.

@@TheDenyingDutchman I squeezed and snapped the top of one of those Chinese boats onto the bottom of an Indian boat that was also broken. It's kind of a cute chimera but I haven't made anything with it yet. Going to try something along these lines. I really want to make something simple that lasts. kzfaq.info/get/bejne/a8-nitpit9Cwomg.html

@@Resonanttheme That's a nice thermoacoustic experiment! Looks like it performs a bit better than a simple coil type pop-pop engine.

Insulating the coil from the tubes is probably the easiest solution for copper coils, but I gave up on this boat. It's a nice shelf queen.

@@TheDenyingDutchman It may be that the copper exhaust tubes would benefit from being more partially submerged in water. Often it makes a difference on some of my tests where dipping more of the exhaust end in water provides a better hot/cold gradient for heat transfer.

This particular D10 is indeed from the seventies. Great little engines, which are being produced nonstop (with only minor (cosmetic) changes) for about 60 years now.

@@TheDenyingDutchman Thanks, I've been trying to figure out what model mine is, but now I'm pretty sure it's a D10 just like this one. I did order some fuel pellets and oil, going to try to get mine going.

Any fine mesh will do, I just used a piece of fabric that I had laying around. The table is an old Intex accessory someone gave to me. Never saw them before, or after. I guess it's 20 years old by now, maybe even older.

Bottom of the pool feels soft, but not too soft. The weight of the legs do leave a permanent imprint on the foam, but does not destroy it. Since this video I only have tiles under the liner of the pool.

@@TheDenyingDutchman Wouldn't that keep the legs lower than the rest of the pool. The weight of the water might stretch the liner down from the top. I'm afraid it would rip. That's why everything should be on the same level. But in your case it shouldn't be a problem. Your tiles are not 1" thick.

@@emeresbestres1 True, but these foam tiles are about 0.2 inch thick. Not something to worry about.

@@TheDenyingDutchman Thanks for quick replies. You have a nice set up. I just poured a 17x17 slab in my yard so no more leveling issues but I need those tiles for under. I think I paid close to a pool price for those tiles but it should last for a long time I hope. Did you see them fading from the sun?

@@emeresbestres1 They eventually discolor, but more because of dirt. They are quite water-repellent, but dirt still embeds itself into the foam.

It has two propellers to steer. (And one propeller to dive)

Unfortunately no, I would love to have one myself.

That's unfortunate. Tell me which part of the video is unclear so that I can help translate my gibberish.

I can't remember 10 or 15 minutes if I recall correctly. It is broken, got to love Chinese junk... ; )

@@TheDenyingDutchman what do you mean it is broken? like will it brake in 1 second or something?

@@wosaks9649 It lasted about one summer, it developed a leak quickly (never go deeper than about 50cm) and although I did let it dry properly (after removing the screws) it still failed.

@@TheDenyingDutchman ok thank you for the information appreciate it.

@@TheDenyingDutchman One quick question. I have it but is the charging port waterproof againts chlorine? or will it rust if in contact with chlorine?

Unfortunately, as with all cheap toys there is not much information (if any) to be found. My best guess is that is was made in the fifties or sixties. Value can be anything between $10 to maybe $50 depending on condition.

Not sure what gauge the diaphragm is, the brass sheet was about as thin as paper. I soldered the engine upside down on a firebrick so that the diaphragm only received radiant heat. Because the boiler is shaped like a square Brodie helmet only the edges of the brass sheet burn up. (It becomes as brittle as burned paper) But that is no problem, since the capillary action of melting solder ensures the entire brim is covered in solder. Besides the inevitable metal fatigue, the engine is indestructible. (I have no clue how many hours (or days?) it takes for the engine to fail because of metal fatigue.) I hope that answers your questions.

@@TheDenyingDutchman Hello Thank you for taking the time to answer my questions I really appreciate it . Has your design diaphragm type engine held up well is it still running nicely . Am I correct in saying the key to all of this when using hight heat required for silver soldering is the fire brick you mentioned above. Even heat displacement when soldering especial when working with silver less chance of hot spots causing the brass shim stock or thin sheet brass to warp or distort when applying the heat . Do you recall how long it took for the silver to flow properly . I have been all over looking for the best option in solder to use of pop pop engine. I have some plumbers solder it says 4% silver ? but not sure read somewhere lead free solder can cause weak joints with brass ? Also what torch did you use when soldering . Any additional help on best solder to use advice on ones you have tried and have seen good results would be appreciated David your pop pop boats are great !

@@gofast1394 Plumbers solder melts at about 200 degree C. commonly referred to as soft soldering, which is no good. Hard soldering/silver soldering/brazing, is done at more than twice the temperature, exceeding 450 degree C. That's why a firebrick is quite mandatory, the workpiece will become red hot before the solder starts to melt. A regular hobby grade blow toch will do the job for small objects like pop-pop engines.

Hello thank you for the response back I appreciate it . Question did you notes any difference in the metal after the thin brass was exposed to the high heat from silver soldering or hard soldering . Did it seem to get somewhat brittle at all ? I read brass has a somewhat high tensile strength when compared to copper for example, making it more susceptible to stress cracks as it is stiffer than copper which I believe is where brass originated from correct if wrong on that David

@@gofast1394 When heating brass to the desired soldering temperature you're actually annealing it, making it more flexible, which can be very useful for bending brass tubes for example. Problems only occur when overheating, brass is a copper/zinc alloy. I'm not sure if zinc leaches out or is burned up if the temperature is too high.

The boiler of this engine doesn't contain any water, only superheated steam and air, water is oscillating in the tubes, occasionally water "overshoots' into (or near) the boiler where it - quite violently - flashes into steam. The engine is brazed (silver soldered) so it can withstand virtually any temperatures. It's horribly inefficient and has no practical use whatsoever, besides toy/model boats, but I like experimenting with these kinds of engines.

I didn't know that. Good to know, next year or so I want to do a garden overhaul and make the tiny pond quite a bit larger.

I have no clue, maybe a seed?

This is the vid you are looking for. Didn't make any other vids.

In this setup I used a 1000gph pump on a 1500 gallon pool, with no other attachments, which was more than sufficient. My current setup has a thru wall skimmer, a chlorine feeder and solar mats, so a larger pump was needed.

Thank you, I'm glad the video was helpful.

Thank you.

Sounds good. Unfortunately we don't have discounters like Harbor freight and Wall Mart in the Netherlands.

Fortunately you can open it and let it dry. if I remember correctly you have to twist the front to get it off, after you removed the screws of course.
