Class 6 Assignment(Final) - Intro to Fibrication

During this semester, I learned a lot about different materials and method. How to make fabrication part for other project. I made wood box, drawer， acrylic lamp, wood candleholder, wood enclosure, wood shelf and button box for my PCOM final. So this week , I want to make something different which I haven't used it before.

Since Christmas day is coming, I decided to make some bow ties. I like wood soooo much, this time I want to try some different wood so I bought a 1/4 *3*24 and a 1/16*3*24 Walnut board from Blick. Some  soft Brass wire from Blick. Necklace and Joint from ToHo Shoji.

1 Design the pattern to the bow tie.

I wanted make wood bow tie in vintage style, so I design patterns in Illustrator to simulate the real wool fabric, also designed dear horn for decoration

2 Used Laser cutter to engrave the pattern at first, then cut it off.

3.  Sanding it

Put some water on it and sand it in both sides, to make it more smooth

4 . Used Laser cutter to engrave the pattern on the other side, use this way to make patterns in each side can connect exactly.

5. Made the dear on it

I want to make a 3D deer in front of the bow tie, cause I like deer so much and it's also fit the Christmas atmosphere.

Made the template for it, I used 1/16*3*24 Walnut board to make  a tinny dear. Used basswood as experiment.

6. Use super glue to attach all component together.

7. Use  soft Brass wire on the dear horn. (I want to make the horn more stronger, and the color of this piece of walnut is pale， add some golden color to make it more attractable, but it does't work really well, since the horn is so fragile and easy to be broken by the wires during the process.)

Here it is

And I also used fabric in the bow ties' center to make it more adorable.

Week5 Assignment- Intro to Fabrication

  [embed]https://vimeo.com/113942348[/embed]

This week, we learned distinguish different materials and fasteners, we should use two materials to make our works this week.

I want to make a colorful button box for my PCOM project- something like color palette to let user to choose color they want.

At first, I want to use colorful buttons to make the box, but it's difficult to find push button in 7 different colors. Then I thought about putting colorful acrylic board on the button top to represent different colors, and I asked ben, he said it's not a good idea because users may press acrylic board in different corners and the force out of balance may cause the button nondurable. Therefore, I decided to put buttons and acrylic board in different location， avoid them to affect each other, and put them in parallel to show each button represent specific color.

I bought colorful acrylic board from canal plastic center, I hesitated to buy transparent one or static one, then I decided to put some LED under the transparent Acrylic board which can show if users has pressed it successfully.

I designed box at first,  use three layers to build these box (or color palette). First layer  is the 5*24*1/4 pine wood board to set acrylic board and buttons, second layer is 4*24*1/8 basswood board(leave 0.5inch each side to put front and back board which the thick is 0.5 inch) and put super LEDs on it , and the third layer is a piece of 4*24*0.5 pine wood(use the same wood with front and back board in this box.). This layer is to contain all circuit, breadboard, and Arduino board.

First, I used laser cutter to make hole to put buttons and acrylic board. the acrylic board is 2*2, and the smallest diameter of button is 0.62inch , so I leave the acrylic hole to 1.9*1.9 square, button hole is  o.64inch diameter circle

Second, I used Super glue to attach acrylic board on the pine wood (no plastic glue and wood glue, they didn't work in this case) , and put seven buttons on the board. Forgot to take photos in process..

Third, I drilled two row of small holes in parallel, one is to put LED in it, and one is to put buttons' wires through it.

IMG_6409_1Fourth, put all the circuit in the third layer.

Fifth, I used Mad saw to cut the front  and back wood for the box.

Sixth, put wood glue on wood board's each side , arrange them together, use  clamp to make them attach in tightness.Then, used  fasteners to attach piece of wood board together, make the box easy to change and fix in the future.

Here it is!

Week4 Enclosure-Intro to Fabrication

This week we learned how to make an enclosure for the project, How to make it easy to open, easy to  repairs, change batteries, and easy to modify. I make a wood enclosure for the assignment.

I used

a piece of Basswood*1

Toggle switch *1

Illuminated pushbutton switch *1

First，I picked a piece of bass wood in the shop

and rounder it in a nice shape

2.Then I drilled 4 hole in the corner by the drill press.

3. I cut the wood in to two pieces by band saw.

4. Make big holes inside the wood box to make a space to put components in it. I used drill press machine to drill the hole.  I drilled big hole at first, then a small hole to fit the components'  feet.

5. Added components in it.

6.  Then I put the screw in it to make the two piece of wood attach together

Here it is..

Week3 Assignment-- Intro to Fabrication

This week, we learned how to deal with laser cutter. Using different material may have totally different effect.

I decide to make a candle holder， and I used these things:

Hardcard *1

Craft plywood*1  1/8*6*12

Bass wood*1  3/32*6*24

Rod*1

Candle*1

I go to canal plastic center bought some acrylic, but haven't used it finally.

This is my sketch

1. Make the cover for Candle holder

First, I tried some patterns in Illustrator, weren't fit very well.

then I want to use some triangles to make it like a net, I don't know if it can work because the net has very thin lines. I find some pictures on website, and arrange them in Illustrator. and just try it on Laser cutter.

I change the setting to 76,20,2500, the paper card 's setting should be 66,22,2500, but since the line is so thin, I set speed higher and power lower.

I for got to take photo of the out put things..

2. Make the holder

I designed a holder in regular triangle shape, and make a circle in the center (I suppose it have a hole in the triangle to hold the candle) and cut three line near the edge to put paper cover which made before in it. I used wood board to make them. I use bass wood to make 5 holders, and use plywood to make extra 2 of them. (don't use plywood again!! disaster....)

I use 1/8 wood, so I set 30, 60, 100 in Laser cutter according to the reference. but I can't cut successfully in the same set for plywood, so I change the setting to (I can't remember clearly maybe is-)90,90,100 , it has a little fire in laser cut, scary... and the board turn to black...

3. Install holder

I want to attach holders I cut before together to make it thick, but I didn't align them neatly, so I can't put cover in the hover deeply, because the lines in the edge aren't align well. Next time I should attach each two piece of board together once a time instead attached all of them together once. It's really regretful.

Then i put three rod on it.

 

The cover cannot attach on the rod , I want to make another cover, to attach these three pieces of cover together and not be cut individually. Cause the laser cutter has been booked, maybe I should do it in the future.

Finally, put candle in it.

  

  

It seems like there's a lot of pity things in the process, but the more material you have tried, the more confident and comfortable you'll be when you get well with the machines. Making this candleholder is a good lesson to learn how to deal with laser cutter, and I got more knowledge and experience, hope do better next time, hope align neatly at least...

Week2- Intro to Fabrication

This week , we learned different kinds of Jigs, tools to help you make your work efficiently and in high quality.

For our assignment, we should make multiples of something, 5 or more.  The objects must be a multi-process piece.

I wanted to make multiple drawers, just like the Traditional Chinese medicine container. It's small but can keep different tiny things being orderly. Just like the picture.

I went to Home Depot on 23th street to buy the wood materials I need.

BOM

I bought two pieces of big wood board in Home deposit.

3.5*0.75*60 -

2.5*0.75*60

And two thin wood board , one medium wood board from Blick.

4*0.2*24

3*0.5*24 (two)

Then I bought 1/4 Dowel Pin from M&D Shapiro Hardware

First, I made a sketch for my drawer，It was difficult than I thought before, since I haven't make a furniture before, even haven't do something with woods, what's  more, I bought wood material before I designed it. So it spent me a long time to design this sketch to make use of my material (In order to cut less, I made use of material's width to make this size of drawer, next time designed before buying material will be better.)

This is my draft. I bought 4 size wood board, I put serial number to each size of wood. And i noted when I will use each of them in writing their number. It's really helpful, cause drawing draft almost make me crazy....

Second, I saw the small piece of wood according to the sketch using band saw. and saw the long piece of wood on saw machine.

The difficult part of making a drawer is you should make  parallel things in same size, so I then use the previous one as a stop block , In this way I can  make this two pieces of wood in same size and style.

Third, I use rounder machine and sanding-paper to make the it more elegant.

Fourth, arrange all these small pieces of wood. I used dowel jig to make two holes for each piece(the container) ,and then used dowel bits to connect two part together. Then used wood glue to attach 5 inner containers(the drawer)

Here is my Drawer!

     

Finally, I add  small stick on each of them to make its handle.

Flashlight--Class1 Assignment of Intro to Fabrication

This week, we should build a flashlight. I go to  Lighting Plus at first to see if I can buy the bulb, but I found all the bulb need 120V, and cannot work portable with cell battery. So I give up to make a bright bright flashlight... I chose LED to make my flashlight.

Then I go to Canal plastic center to buy some acrylic material which I can use to make the body of my flashlight. There are a lot of acrylic in the shop,I bought a pink tube and a transparent cube. I want to make a bling-bling  fairy stick!

I  used wires, one cell battery, one switch, one LED, an acrylic tube and an acrylic cube to make it.

First, soldering wires and assemble the circuit.

2. Using Router machine  one angle of the acrylic to be flat in order it to attach  with the tube closely.

3. Add the LED

I like the feeling of using drill press, not as scary as I thought before. Now I can get comfortable to use it . I drilled a small hole in my acrylic . At first I want to make a bigger Drill Bit to make a larger hole which can put in my blue LED. But I'm afraid to make my acrylic box broken, so then I turned to use a small  red LED which fit in the hole perfectly, but the light is not perfect, it's a little bit dim.

It will light in the dark environment.
