Wrench for Car Counter

Introduction: Wrench for Car Counter

This is a wrench for the cap on the car counter at Hillbrook School. The Technical Director at the school, Mr. Selak, asked me to make something to take off the cap on the car counter. The cap is hard to take off and if you do get it off, it hurts your hand. I tried to make something that fixed this problem. This wrench requires the application, Corel Draw, as well as a laser cutter.

Step 1: Changing Size

Go into the top left of the screen and change the size to 11x11.

Step 2: Making the Wrench (Polygon 1)

Start by using the polygon tool to make two 16-sided polygons (image 1-4). One of them will be smaller than the other. Draw a straight line through the polygon to split it in half using the 2 point line tool (image 5). Click on the crop icon and select "virtual segment delete" and delete the right side of the polygon, and the line (image 6-7).

Step 3: Making the Wrench (Polygon 2)

Click on the pick tool and select the polygon. Use ctrl-c to copy the half-polygon.

Step 4: Changing the Polygon Size

Make sure the size of the polygons are exactly as shown the pictures. Image 1 is the bigger polygon and the smaller one is shown in image 2.

Step 5: Connecting Lines

Use the 2-point connector to connect the two sides of the bigger half-polygon (image 1-2). Then use the virtual segment delete to delete the line in between the two sides of the polygons (image 3). After you are done it should look like image 4.

Step 6: Making Handle

Use the 2 point line tool to make a handle (Image 1-3). Then use the Virtual Segment Delete to delete the line that separates the handle to the wrench.

Step 7: Keyhole

Use the ellipse tool to make a hole where you could fit a key ring.

Step 8: Finalizing

Click control-p to open the print window. Then click preferences and go into advanced. Click "wood" and then click load (image 1). Go back into general and change the size to 11x11 (image 2-3). Look unde "job type" and select "Vector". Hit okay and then apply (image 4-5).

Step 9: Printing

Turn on the air compressor and the filter (image 1-2). Then, turn on the laser cutter (image 3). Find a piece of wood that is or bigger than 11x11 and put it in the laser cutter (image 4). Go back to the computer and click print (image 5). Make sure it says the name of your project on the display section, if it is there, hit go (image 6). Then, it should make the wrench!

    Good first post, but I am going to offer some constructive criticism for any files or presentations in the future -- use screenshots to share images of your display, not photographs of the actual monitor display. It sounds like an petty detail, but I guarantee using 'Snipping Tool' or any equivalent software for capturing screenshots will make all the difference in the perception of professionalism -- regardless of the document type. Screenshots avoid any interference lines (Moiré Patterns), glare, perception distortion, interlacing, etc., that will certainly be present on photographs of the screen -- plus, in one step you'll have the finished without the need* for cropping.

    In case you aren't familiar, you can access Snipping Tool by either pressing the Windows key or clicking the Start menu. Begin typing 'snip...' and press enter when 'Snipping Tool' is highlighted and a small floating window will appear. Select a mode from the 'Mode' dropdown based on what you want a screenshot of -- 'Rectangular Clip' and 'Window Clip' will likely be the main modes used. Click 'New' and, based on clipping mode, make the screenshot selections accordingly. By default, the screenshot will be copied to your clipboard for pasting directly into files/programs where possible; however, you can also annotate/highlight the image, save the image as a PNG, or send directly to a printer.

    That's a good way to make your own custom tools :)
