Title: Autovapor Mad Max - homemade
Post by: juandedios on February 25, 2014, 09:44:24 PM
Hello,
I would like to show the first engine I built.
I've designed and built only with an electric drill and hand tools.
This is the first time it worked, it was the third attempt:

My wife told me to do a vehicle and built this:

For hand tools and a drill you have created some really cool items. Great job man!

Thank you.

I have greatly improved with the construction of vehicle wheels and a few other things:

A first engine with boiler is pretty amazing.
I'm betting you had a lot of fun with that.

Very well done Juan, I am trying to imagine what you could achieve when you have a lathe and mill. :NotWorthy:

Very cool models Juan!
That's pretty amazing work!  And to have done it with such minimal tools is truly incredible!
Thanks for sharing the pictures and videos with us!

Thank you for your message. I am very happy to be with you.

The vehicle had trouble turning. To fix it I built a spread.
Changed rear traction and steering axis front.
It works much better, this video shows the result:

Hello,

As weighed 21lb lacked strength.
I changed the cylinder 1/2 "to another 5/8". The power increase is remarkable.

Engine Features:
1 double-acting cylinder.
diameter: 5/8 "
stroke:  1 27/32 "

This project has helped me to learn. When I did not know how to weld, I've never seen an engine, only in photos. The experience has been rewarding.
I am currently building a bigger boiler, I hope it has improved. When the show's finished.


Learned what I am building a 2-cylinder engine. I will create a new topic in "Design Your Own"

I do not put more text for the difficulty me, sorry.
Thanks mates,
Juan de Dios.

Hi friends,
I want to show my design for the new boiler of my vehicle.
The largest copper tube that I have is 54 mm. in diameter. I have designed a double boiler for greater capacity.
I'm cutting the pieces.

Hello,
I have prepared all the pieces of the boiler and have welded copper rod phosphate one of the bodies.

(http://imagizer.imageshack.us/v2/320x240q90/811/xv5p.jpg)   (http://imagizer.imageshack.us/v2/320x240q90/132/o9rz.jpg)  (http://imagizer.imageshack.us/v2/320x240q90/706/3x42.jpg)

(http://imagizer.imageshack.us/v2/640x480q90/834/lg7a.jpg)

Wanted to make sure everything was fine doing a pressure test with water. To pump the water to the boiler I made a non-return valve and a cylinder with a piston to inject the water (build another non-return valve and fabricate pump) to try to fill it with water and placed a pressure gauge, to push strongly reaches 12 Kg / cm2.

(http://imagizer.imageshack.us/v2/320x240q90/706/0j0h.jpg)   (http://imagizer.imageshack.us/v2/320x240q90/836/l8e9.jpg)   (http://imagizer.imageshack.us/v2/320x240q90/59/lsj9.jpg)

Tapé all the holes in the boiler, fill with water taking care not to let air in, put the check valve and connect the "syringe" giving pressure to the 13Kg./cm2. There is a small leak so I've reviewed the welds and will try. The end caps are slightly deformed due to pressure but have held up well considering the boiler worked to a maximum of 3kg/cm2.

Greetings.

I do like your double boiler. Here is mine, bigger at 63mm tube with 28mm fire tubes so I could get a low centre of gravity.

Hi Juan, some great stuff here, love the videos. What is the material used to line the boiler casing in the last photo?

Cheers, Hugh.

(Just realised it was Hammers response, beg your pardon!)

Following along Juan.
I enjoyed the videos.

I hadn't seen a double boiler before. I'll be interested in seeing more.

Not high jacking Juan's build Hugh. But I will tell you it is plumbers soldering mat.    :hammerbash:

Post by: juandedios on April 14, 2014, 08:56:16 PM
Thanks Hammer,
Your boiler is superb. Where there are more photos and information.
I do not understand your last post, sorry.

Hello Cheers,
The boiler is copper tube 1.5 mm. thick.
In the last picture shows just a body. When you finish the other body will unite.


Hello Zeeprogrammer,
There are few double boilers, look at the Hammer is very good.

Thank you all for your messages.
Greetings fellow.

Juan, do not worry about not understanding some of my last post, lost in the translation I guess. 
Difficulty getting photos as the boiler is in a boat. That is the reason for the twin boiler as I need the centre of gravity as low as possible.  I do have another boiler of strange design which was fitted to this boat  before.  I will look out some photos of this and post later . Hammer

I know that boiler, it's in the Harris book, but can't think of its name. How does it go in comparison to more conventional types? I'll have a look at the build log when I've got a bit more time. Hugh.

Post by: hammer on May 02, 2014, 04:10:52 PM
I must apologise to Juan for invading his site.
Hugh, Mister wedge designed the original boiler & it takes its name from that, Wedge Boiler nothing to do with shape. The reason for the new boiler was to get the centre of gravity lower. The other disadvantage with the wedge it needs a good supply pump, not connected in the video so hand pump in use.  See running here. KtMKpGHblHc

Thanks for that, do you have a powered pump fitted yet?

Hello fellow,

I have looked at the links and videos that comment. I liked and I've learned.
They can post whatever they want, I do not care, it's a compliment to me, thanks.

Can not imagine what it cost me to make welds with copper, because of course my lack of experience, but has helped me to begin to control things a bit.
Soldiers and the two bodies leak I proceeded to unite them and to have them pressure test to 10 Kg
So much was clear but had not thought beyond, after thinking many hours I got to work with the smoke box and subsequently the home.

(http://i1254.photobucket.com/albums/hh608/enginesjohn/Hogar1_zpsefa2fd6c.jpg)

I'm happy with the result and some first tests I've done I think will give good performance. Now think of the burner that had not yet clear to me either.

Hello!

 I have had some personal problems and I have not made works. I am already better and I decided to construct an alcohol burner for the boiler:

I have connected the boiler to the motor of two cylinders and this it is its aspect:

Juan. I do like your work.
 As for my wedge boiler I did fit a pump driven off the paddle shaft. With a bypass valve fitted. But I was given 200mm of 60mm copper tube, so I have built a twin tube boiler similar to yours. Mine if a fire tube as opposed to a pot boiler as yours.

Hi Juan, good to see you back in the shop. This engine is running like hell. Do you build a boat for it ?

Friends thank you very much for your comments.
 I want to show the progress:

Hi,
HAMMER thanks for showing your boiler, is similar to mine. I learn a lot from watching you work.

This video shows how to built my boiler:

As they saw the car now has direction:

Also it changes the transmission ratio of 3: 1 to 2: 1, even more can be decreased for speed.
