can you use regular straws

[sciencetoymaker]

@dariustheking11 Do you mean no bend? I started out like that but it's hard not to overfill the boiler with water.

[kellybolin]

instead of an epoxy i used spray on duct tape and it works better since it gives more room to bend while working with the project...yeah who knew they made spray on duct tape!?

[sciencetoymaker]

@kellybolin By far the most common comments involve finding an alternative to epoxy. There are a number of adhesives that would hold the straws in, but does your method seal all the leaks and hold up to the heat? If it does all that--actually works, in other words--you might consider sharing your method via a video response. I've tried to find alternatives, but many good ideas have fallen to the wayside when I actually tested.They leak.

@sciencetoymaker it works like magic.

[30seann]

can you use the glue gun that you said :10 watts?Plz respond

[sciencetoymaker]

@30seann No, that part gets too hot.

Slater

[daritonify]

Your instructions are perfect Thank you ;)

[12shonte]

what is the width of the engine?

[sciencetoymaker]

@12shonte Well, there is a pattern. But if you can't print it out the middle is 1" and the side flaps are 1/4" each. And as long as the alumimum

[12shonte]

can i use jb welding glue

[sciencetoymaker]

@12shonte Yes, JB Weld is just a brand name of epoxy.

[mrRaleigh97]

i cant find 6mm straws is 5mm ok

[sciencetoymaker]

@mrRaleigh97 Yes, I have made engines with the thinner straws. However, some of the engines have worked well and others have not, and I don't know why. So there's a bit more chance with the smaller straws.

[keivo2]

done.

[hheywire]

well u were right i pushed to hard and it came out the other end

[Talabera2020]

@hheywire How that happens? the other side is the folded one...

[aderonn]

lol i know you want people to follow your plans for the first time and im trying to but would gorilla glue count as epoxy?

[sciencetoymaker]

Follow directions exactly, including ussing epoxy, the first time. After you get an engine that works, then experiment with other glues. Epoxy is readily available.

Slater

[brayam12345]

how about crazy glue

or wood glue

[sciencetoymaker]

Use epoxy and follow the directions the first time. Once you get it to work try variations--like a differnt glue.

what about rubber cement will it work for the boiler?

[sciencetoymaker]

re: rubber cement instead of epoxy: Hmmm, I don't know. Does someone want to try? You have to get the glue in between the layers of aluminum, so it would take longer than normal (over night?) for it to dry (the solvent to evaporate). Heat would help speed up the drying, too. It might work.

Slater

[masterpoop67]

i might try it ill tell you if i do and how it works mk

[thdrjsdnBRB]

can you use hot glue gun for the whole process?

[sciencetoymaker]

@thdrjsdnBRB No. the rest of the engine gets hot, which would soften the hot glue. Follow directions exactly the first time, then experiment.

Slater

[azhar1295]

my straws melts

[sciencetoymaker]

You'll have to provide more detail.

[MbDproductions2009]

can this also work with normal glue?

[sciencetoymaker]

re normal glue: Obviously it will not work with water-soluable glue (the engine has water) or hot glue (the aluminum part gets how). I have never tried a solvent kind like Duco cement. If anyone has tried it, let me know and I'll pass it on.

[nunvikingsofthesea]

how about white glue?

[sciencetoymaker]

No, white glue melts in water. I strongly encourage people to follow the directions exactly--including using epoxy--for the first engine until you get one that works. Then experiment.

[sergentpersonsballs2]

wats epoxy?

[sciencetoymaker]

Epoxy is a kind of 2 part glue. Is made under lots of different brand names.

[AlexFaulkner2294]

can i use hot glue on the side instead of epoxy

[sciencetoymaker]

You can use hot glue for cooler parts of this project, but not the boiler itself. Hot glue will not work.
