can anyone tell me how to see the instructions , it`s under construction plzzzzz i want to make it

For those who cannot see the instructable download the pdf.

what is the pdf???????????

I made the Hardware Store Steam Engine over April break last spring very good instructable Thanks Kyle

Hey kyle, or anyone who finished, i was wondering how the gas makes it from the inlet tubes to the pivot arm and then to the cylinder.


I've unpublished your Instructable while you make your changes. You can find it in your Drafts and go ahead and publish it again when you are good to go!

Thank you Nicole! I hope to be done reworking all of my instructables soon!

Hey myakka, could you at least post a schematic. It looks like the page expired.

Download the pdf

Sorry, when i said piston housing i meant cylinder. What kind of loose joint does that have?

FYI, i had a busy week! i will be on sometime this weekend to answer some of the questions that were asked this week. Thanks!
Come on man, why has the page disappeared? You should create a video to replace it or even a comment. It is really cool.
Fantastic design. I think I will build this over the weekend.
only one question- where is the escape valve?
Please, would anyone who remembers the page before it disappeared tell me how the piston housing is able to move.


Will increasing the size of cylinder and piston increase the speed and power of engine?

it will increase power but if anything decrease the speed. Also can you see this instructables because nothing is showing up for me?

why has the page disappeared?

it's happened to me right after I bought the supplies and I am pissed

here is my design i just finished. it is a vertical compact design that would be easier to use for making moving models like a boat or something. all the stuff needed for this can be bought at the hardware store just like kcbford1's.
im way to obsessed with this instructable.

I'm just wondering if that us a 2 inch caster wheel. Please email the reply to emslicol000@isd284.com or text me at 763 478 1303

Where does the steam come from? Do you have to pump hot water/ steam into the engine or could you out some sort of heat source under the tank?
You put water into a boiler, and have a heat source under it. For this, you can use basic sterno from the grocery store, or denatured alcohol available at any hard ware store. and you can make a boiler from a empty spray can, or a propane tank used for soldering. PLEASE NOTE, that it is always a good idea to put a SAFTEY VALVE on any steam boiler, you can buy them from companies like "Ministeam.com" who sell model steam engines and model steam engine parts, hope this helps. Any questions please feel free to message me. P.C.
Yes. If you take a tube the correct size and fill it with epoxy it will work

I am going to combine this with the desktop steam boiler and make an R/C car !
Have you completed this yet? I am in the middle of combining these two projects aswell. I have the boiler complete, now to move on to this engine!
hey just wondering if you have completed this? I stopped building it because it became impractical and a lot of work

was wondering if copper pipe and piston diameter can be increased? And if so does the safety ratio go down when powered by steam?

Do you remember by chance how much this total project costs to construct?
Also, how might I hook it up to a toy car or something to power it?
What if the steam cools down below the boiling point before exiting the cylinder?Could there be water accumulation and how would that affect the engine?

Very clever design by the way!
with the right alternator/generator combined with a buffer battery, this engine should generate more than enough power ( but not too much more) to charge a smart phone, it just depends on the coil dimensions of the alternator/generator and the rpm of the motor.
actually, since it's low current, you could probably use a dc motor as a generator, just make a battery charging circuit.

Could you make this out of PVC piping?
only if you planned to use compressed air, to power it. if you wanted to use steam, you would need to use metal tubing.

Here is one I just finished, made out of glass.


I put a sequence on my blog.


For what it's worth......
Do you have a how to video?
Unfortunately no. I do tutorials with photo's but this one was just a prelude to figuring how to build a steam machine out of gem stone.
Check out http://youtu.be/HhAkS0vWsEo
And just for interest sake, I put up a tut on my blog yesterday, unrelated to engines but concerning jewellery .
I have a lot on my website http://meevis.com/jewelry-making-class-list.htm
Nevertheless, It was your original tut that started all this (grin)
My wife has been heard muttering things like second childhood and senile...etc.
Cheers, Hans.
Do you think it is possible to make the pipes 2 inches and increase the power. I am trying to build a steam locomotive and am hoping this piston will work... Thanks
