How To Make A Popsicle Stick Mini Adirondack Chair

Posted on April 23, 2012 at 6:10 PM Comments comments (36)

In this blog, I am going to show you how to make a mini Adirondack chair like the one seen in my 800 Popsicle Stick Birdhouse w/ Mini Adirondack Furniture.

First, you are going to need tools and material for the chair.Here is what you are going to need:

  • about 10 standard size (1/16 x 3/8 x 4 1/2") popsicle sticks
  • saw, knife, or scissors to cut the popsicle sticks
  • ruler and/or square to measure and cut square cuts
  • pencil
  • super glue or hot glue
  • PDF pattern can be downloaded by clicking this picture below:
  • If that doesn't work for you, click here.



Step 1:

Cut one popsicle stick in half and use the pattern to make the back legs.

  

Step 2:

Use the pattern and cut out the front legs, by cutting one piece to length and then cut it in half to make two legs.

Step 3:

Use the pattern and cut the front support and glue it 13/16" from the bottom of both the front legs.

Step 4:

Glue on the back legs and make sure that all the legs lay flat on a flat surface.

Step 5:

Use the pattern and cut out the back supports, which are the same size as the front legs. Use 2 popsicle sticks as spacers from the front legs to the back support and glue it on.

Step 6:

Use the pattern to cut out the back rest pieces using the rounded ends of the popsicle sticks as the tops of the back rest.

Step 7:

Use the pattern to cut out the seat slats, by cutting 2 pieces to length and then cut them in half.

Step 8:

Glue on the back rest, keeping them centered and square with the bottom back support. Then glue on the seat slats, starting with the front and evenly spacing them to the back.

Step 9:

Use the other back support cut in step 5, and glue it 3/4" from the bottom back support to the top of this back support.

Step 10:

Glue on the arm rests onto the front leg and upper back support. The best way to do it, is to eyeball it and get it in the best looking location, leaving room for the arm rest support in the front, which could also be glued on.

And you're done!

You can also apply a finish, paint, or keep it just plain wood.

Thanks for reading,

Making a CNC Router Part 4: Electronics

Posted on May 10, 2011 at 4:28 PM Comments comments (9)

 

After a few months of saving money, I finally got all the electronics for my CNC!


I purchased all the electronics from: http://buildyourcnc.com/electronicscombo.aspx

which include:

(3) 425 oz-in stepping motors

(3) Drivers (3.0Amp 24-40 Volts, 1-1/64 microstepping)

(1) 36v 8.8a Power Supply

(1) Breakout board

Then I built a box out of poplar and Plexiglas to house all the electronics:









Then I tried out the monitor shelf that I came up with in the last blog and I got a new monitor and the shelf was way too small:



I also got a new computer and needed somewhere to mount it:


So, I came up with this 2.0 version of my monitor shelf (bigger and better):



I also added a few switches to control the CNC:


The “Router and Shop Vac” switch controls this outlet that I wired up and plugged in the router and shop vac:


Then I got an E-Stop and limit switches from CNC4PC: (I still need to wire them up)



Here is a video of me wiring the electronics:

Making a CNC Router Part 3: Updates and Need Ideas

Posted on March 16, 2011 at 2:12 PM Comments comments (3)

I have not had much time or money to work on my CNC lately, but I did make some progress. Here are some of the things I added to it so far:

I added two shelves for the computer and electronics to go on:


I also bought 4 cheap casters from Harbor Freight and installed them:


Also, on an unrelated note, my dog loves the new shelf and sleeps on it all the time:


Now for some ideas:

I need some where to mount a computer screen to use for the CNC and I have a few ideas, but was wondering if anyone can build on them before I start building it. (haha)

This is what I got so far:




I would like to mount it on the end here but I think it might get in the way because it sticks out 8” from the table. I was also thinking about making it so it can fold down but the motor would be in the way. I also cannot mount it on the side because it would be in the way of the x axis. The monitor also cannot fit on the shelf and I would not be able to see it. I would like to have the computer monitor be mobile with the CNC, so it cannot be mounted on the wall or something. So far it looks like I am going to go with my idea but I know someone can add or give me a better idea.

I am currently working on saving up money to get the electronics for the CNC and hope to start getting them next month. I have been cleaning out my closet and selling all the junk I don’t need on Craig’s List and I have also been looking for a job to save up money. My dad also said he will help me out with buying the electronics so I can get this done sooner. I also want to thank everyone that donated on my website, it helps me out a lot!

All your ideas are welcome!

 


Making a CNC Router Part 2: Making the Stand

Posted on February 25, 2011 at 1:56 PM Comments comments (1)

Well today I didn’t have school due to a snow day, so I figured I would work on my CNC some more. I knew that I needed a stand to put the CNC on and to make it sturdier, so I was off to Google SketchUp! I wanted to make the CNC about counter height, so I made the stand 34 1/2” high plus the 1 1/2” table of the CNC makes it 36” high overall. Here is the simple design that I came up with using 2×4s for the stand:


So I was off to making saw dust!

First, I cut five 2×4s up to get all four legs and eight supports:


Then I drilled pocket holes in the ends of all eight supports:



Here is a video of me assembling the stand:

Here is the stand completed:



I also got all the threaded rods in all 3 axis:







I did receive quite a few questions about my CNC so I will answer some of them here:

Q: What do you have in mind for the software?

A: I have Mach3 and LazyCam. Not familiar w/ them yet because I have not been able to use them. I also am using Google SketchUp to design the projects and then I got a plugin to convert them into g-code.

Q: What size working/cutting envelope for your cnc?

A: The table size is 2’ x 4’. The cutting envelope is about 19” x 38.”

Q: What materials/projects are planned for your machine?

A: With this CNC, I plan to make custom signs, hard to make pieces for projects, I might play around with making 3D stuff, and whatever else I could use it for.

Q: Is the CNC in your room? Besides being noisy they get really messy fast.

A: Yes, this CNC is in my room. But I defiantly do not plan on using it in my room. Right now I have it in my room only to assemble and test out the electronics(when ever I get them)

Q: What type of electronics do you need?

A: (3) 425 oz-in stepping motors

(3) Drivers (3.0Amp 24-40 Volts, 1-1/64 microstepping)

(1) 36v 8.8a Power Supply

(1) Breakout board

(1) Cooling Fan

Here is the website that I plan on eventually buying them when I save up enough money:

http://buildyourcnc.com/electronicscombo.aspx

Also, I just wanted to let everyone know that there is a donate button on the left hand side if anyone is interested in helping me out. You can donate any amount you want (even a penny if you would like) and I would greatly appreciate it and I could get this project done a lot faster.

I know someone is probably also going to suggest that I should make shelves on the stand. Well I plan to make two shelves, one for the electronics and computer to be mounted on, and the other for random stuff/ accessories. I also plan on closing the electronics in with Plexiglas to keep the dust out. I also plan on getting caster (wheels) for the stand to make it easier to move around. These are the casters I want to get from Rockler.com:

Making a CNC Router Part 1: Assembly

Posted on February 23, 2011 at 1:26 PM Comments comments (9)

Well I just turned 17 years old today, February 23, 2011, and I have always wanted to make a CNC router. So for my birthday, I asked my dad to get me a CNC hardware and plans kit from www.buildyourcnc.com. Then I went to Lowes and the Home Depot to get a sheet of MDF, aluminum angles, threaded rods, and various other items I needed to make the machine. So the whole weekend last week, I’ve been working on cutting all the parts I need and then drilling all the holes in the pieces. Here is my progress so far:

Plans and hardware I got from www.buildyourcnc.com:


Parts I cut from a single sheet of 3/4” MDF:


 


I used my small dremel tool drill press to drill all the pilot holes, since I don’t have a real drill press.


Then I drilled all the holes:


 

 



In the plans, this is how it shows to attach the nuts for the threaded rods to go through:


I did not think this method was strong enough so here is what I came up with:
First, I got a piece of plywood and cut a hole in it to fit the square nut and glued it down:


 


Then I cut another piece of plywood and dilled a hole a little smaller than the nut (so it wouldn’t fall out) and then I glued it to the other piece of plywood:


 


Here is the CNC all done:


 

 



...And here is a video of me assembling the machine:


You need Adobe Flash Player to view this content.

Now I have to save up about $400 for all the electronics to get it running. Will post when I get that far. (May take a while. haha) Let me know if anyone has any advise/questions/comments/suggestions! By the way, the table size is 2’x4’ and the cutting envelope is about 19”x38”

Thanks,

Kyle
