Cartman Sign




This is just a simple Cartman sign that I made for fun.  Its about 12.5 inches by 13.5 inches.  I made the Cartman sign using a carving program called Aspire on my computer then carved it out using a CNC machine. Masked and painted it and all done.  This is my first Instructable so bear with me. ;)

Step 1: Creating the Cartman Sign Using Aspire.

Using Aspire I made the rough vector outline of the Catman head.  I then created some cutting paths for the CNC and lastly added some color just for looks.  Gives you a better idea what the finished product will look like.

Step 2: Preping the Wood.

After the Cartman head looks like I want it in Aspire I need to get my wood ready.  I'm using half inch MDF. It carves nicely and makes a nice sign.  First thing I do is clean dust off the wood.  Prime the wood so the paint sticks better, sand and paint.  After the paint is dry. I cut a sheet of masking that will cover my MDF.  This will make painting easier later.  Make sure the masking is flat and smooth. No bubbles.

Step 3:

After your done masking its time to make the magic happen.  I loaded my file from Aspire into the CNC machine and watch as the Cartman head comes to life.  This is the fun part.  After changing a bit and cleaning all the dust off,  the Cartman head is ready for paint.

Step 4:

This is where the mask comes in handy.  With the mask on I paint the black everywhere the CNC cut the wood. Everywhere that I want black that is.  The mask keeps paint from getting on my first layer of paint that I already did.  And with the mask there is no need to stay in the lines.  I was never good at that anyway.....

Step 5:

When all the lines are painted like I want them I remove the first layer of mask.  This will reveal the paint from before.  I then paint my new color over the old paint layer and try to stay in the lines this time.  The first pic. I paint the yellow part of the hat.  When thats done I remove the next layer down of masking and paint that part light blue to match Cartmans hat.  When thats done I remove the mask from the eyes and paint them white along with the teeth.  Got to have nice white teeth right?  When all the masking has been removed I go back over it and make any touch ups that I need  to and your done.  Cartman Head sign.

Step 6:

After all that work, its PEANUT BUTTER JELLY TIME!!!!

Thanks for looking at my first instructable.

    Hi hoozer,
    Great tutorial. I like the tip to remove one layer of mask at a time. I've been in the sign business 20+ years so I guess I can still learn something.  I find it difficult to find MDO with a paper overlay at the building supply centers, I usually have to go to a specialty wood supplier or sign wholesaler. I also like using One Shot paints to grip the board really well. You can also find mask from a local vinyl sign letter shop.

    Look forward to more tutorials.
