Step 2: Cut the Pieces

STEP BY STEP

1st - Cut the pieces

I preferred to use the 1 / 2¨ threaded tube (for hot water), but you can choose to use another type of PVC pipe with the same diameter, that is OK.

Cut 3 pieces with the following measures:

01 - Piece with 4 inches

02 - Pieces with 8 inches

__________________________

PASSO A PASSO
1º - Cortar as peças Eu preferi usar o cano roscável 1/2¨ (para água quente), mas você pode escolher usar outro tipo de cano de PVC com o mesmo diâmetro que não tem problema. Cortar 3 peças com as seguintes medidas: 01 01 Peça com 10cm

02 Peças com 20cm

Step 3: Making Threads in the Pipes

2nd - Making threads on the pipes

When you buy a PVC pipe, it may occour that one or both of the tips are with the thread made, but when cutting the piece into smaller tubes you will need to do the thread. For this you should use a thread maker, they are various sizes to be used in PVC pipes of different diameters. With the 1 / 2¨ thread maker, you can thread the pipe of the same diameter.

The threads can be made by holding the tube in one hand and the thread maker on the other or, or using a vise to hold the pipe (that is what I did), so you have more stability of the pipe and can make the threads with more precision.

______________________

2º - Fazer roscas nos canos
Quando você compra um tubo de PVC pode ser que uma ou as duas das pontas estejam com a rosca feita, mas ao cortar a peça em tubos menores você vai precisar de fazer a rosca. Por este motivo existe as tarraxas, são vários tamanhos para serem usados em tubos de PVC de diâmetros diferentes. Com a tarraxa de 1/2¨ você pode fazer a rosca do tubo do mesmo diâmetro. As roscas podem ser feitas segurando o cano em uma mão e na outra usando a tarraxa ou usar uma morsa para segurar o cano (foi o que eu fiz), assim você tem mais estabilidade do cano e consegue fazer as roscas com maior precisão.

Step 4: Holes in the Cap

3rd - Holes in the cap

Make two holes in each cap, one in the center and the other a little off center (see video).

The center hole is where the screw will pass and the hole below is used to pass the electricity wire.

_______________

3º - Furos no cap
Fazer dois furos em cada cap, um no centro e outro um pouco mais abaixo. O furo do centro é onde vai passar o parafuso e o furo mais abaixo serve para passar o fio de eletricidade.

Step 5: Knee Holes

4th - Knee holes

In one knee make two holes, each hole will serve to pass the parallel wire

_____________

4º - Furos no joelho
Em um joelho fazer dois furos, cada furo vai servir para passagem do fio paralelo.

Step 6: Connect the Pieces

5th - Connect the piecesThe connection of the threaded parts, besides being easier, leaves the piece firmer.Connect the two elbows first in the 4 inches tube and then connect the 8
inches pieces, following this shape is more certain to have alignment between the 8 inches pieces.

____________

5º - Conectar as peças
A conexão das peças com rosca além de ser mais fácil deixa a peça mais firme. Conectar primeiro os dois joelhos no tubo de 10cm e depois conectar as peças de 20cm, seguindo essa forma é mais certo de ter alinhamento entre as peças de 20cm.

Step 7: Remove the Wires

6º - Strip the wires

After the assembled part, it will be necessary to strip the ends of the wires, to pass them inside the cap and to wind the copper in the screw.

______________

6º - Desencapar os fios
Depois da peça montada vai ser necessário desencapar as pontas dos fios, passar eles por dentro do cap e enrolar esta ponta no parafuso.

Step 8: Switch

7º - SwitchPlacing a switch is not complicated, you have to split the paralel wire at the desired switch position. After that, you need to cut one of the wires, strip the tips and connect each tip to each switch terminal.

____________

7º - Interruptor
Colocar um interruptor não é complicado, você vai precisar escolher a altura no fio e cortar um dos sentidos para instalação. Com o corte vai gerar duas pontas, cada ponta precisa ser instalada nas entradas do interruptor.

Step 9: Connecting the USB Cable With Parallel Wire

8º - Connecting the USB Cable with Parallel Wire

Cut the USB cable near the mini USB connector, gently strip the cable near the cutted tip, to expose the internal wires, avoiding to damage them. You will notice that there are 4 wires:Black and Red are for power supplyGreen and white are for data communication.Cut off the green and white wire (we do not need them) and strip off the black and red cables, connecting them to the parallel wire.

___________________

8º - Conexão do cabo USB com fio paralelo
Cortar a ponta oposta do cabo USB, com a ponta cortada e desencapada você vai perceber que existem 4 fios: Preto e vermelho – Eletricidade Verde e branco – Dados Cortar as pontas verde e branca (não precisamos delas) e desencapar o cabo preto e vermelho, conectar cada ponta do fio paralelo a uma cor do cabo USB.

Step 10: Using the USB Connection

9th - Using the USB connection

Your cutter can be used connected to mobile charger source or to a portable USB charger.

Ready, with your new cutter will make it easier to make crafts, school work and college.

How many amps do you recommend the phone charger to be? 750mA? 1.5A? 2A?

[anamarcondes]

In mine has the following information.

INPUT:100-240V - 50/60Hz 0.3A

OUTPUT: DC 5.0V=3.1A Max

[WestWindsDemon]

I don't have any phone charger that goes as high as 3.1 Amps. Do you know of any formula or conversion to get the necessary watts? (X volts vs. Y amps) Thank you!

[johan.j.edman]

I Think that the charger has one 2.1 Amp connection and 1 amp connection. So a total output of 3.1 Amps.
(I could be wrong but most of the chargers I've had with 2 outputs have been that way)

[kjlpdx]

i missed the instructions on attaching the guitar wire

[aaahotdog]

Very nice. I would try to tidy your wiring connections a little better. Watching you strip wires with a box cutter made me worry. Safety first. Thanks for sharing.

"The threads can be made by . . ." buying risers instead of pipe.

Hi, charlessenf-gm!

Great idea, thanks for the comment!

[JamesA41]

Neat idea for a portable cutter. Would be interesting to do the math to see what the size limits are for what can be made now portable with the newer lithium battery packs since are lighter.

[anamarcondes]

Hi, JamesA41!

Great idea, thanks for the comment!

[charlessenf-gm]

Of course, there is no need for threads at all as all the fittings shown are available as SLIP fittings. The Elbows (as we call them in Texas) can be glued in place and the other two fittings would not need to be secured at all (given the design shown).

I would look into the idea of installing a PUSH TO CLOSE switch on the 'handle' part of the foam cutter positioned so that it could be operated by a thumb. With such a switch, one could never forget to turn it off when not in use!

[anamarcondes]

Hi, charlessenf-gm!

'' With such a switch, one could never forget to turn it off when not in use! ''

Great comment!

On the connections, I made this way to show another possibility of making the cutter.

[dschwant]

Where did you get the PVC threader? Yes, the other commentators are right that it maybe isn't needed, but it is very cool!!!

[anamarcondes]

Hello, Dschwant!

Bought at a construction material store. It really is not necessary, you can buy the docking tubes, but I wanted to show you another way to do it.

[Juan C Walls]

The video shows the cutter is ready to cut foam almost instantly when you turn the switch on. Is it really THAT fast?

Is it dangerous if you touch the hot wire accidentally?

Can it cut through regular foam? (the one used in pillows, cushions, shoulder pads, etc)

[anamarcondes]

The video shows the cutter is ready to cut foam almost instantly when you turn the switch on. Is it really THAT fast?

A: Yes, with the USB charger the temperature and the cut is in an easy way, already with the portable charger it heats up but with the end of the battery it will decrease its temperature.

.

Is it dangerous if you touch the hot wire accidentally?

A: No, I touched the wire to know if it hurt and it is hot but not enough to hurt it with the USB connection, already with the connection of the portable charger I did not test.

.

Can it cut through regular foam? (the one used in pillows, cushions, shoulder pads, etc.)
A: Yes, it needs to be carefully because the foam is usually thicker.

.

Thank you for the questions and for watching the video.

Anamarcondes - really great idea & really nice job. Also really like the music you used and your hand signals made it easy to follow for any language user. If you can somehow email or post the name of music artist I would appreciate it. Thank you for sharing !
