Instructables
My neighborhood has the addresses painted on the curb, mostly so emergency services can find your house in the case of an, um, emergency.  The one in front of my house was getting quite worn, so I decided to repaint it. 

Items needed:
spray paint (gloss white, reflective, and semi-gloss or flat black)
template
masking tape
newspaper for masking
TechShop (for making template)

Step 1: Make a template

I used the computers at TechShop, since they also have Laser cutters for the next steps. Also, I don't have Corel Draw on my Mac, and it's available on all of TechShop's computers. 

I used Corel Draw to sketch a 4" tall set of house numbers.  I selected a font I liked, placed the numbers, then used Corel's convert to curves feature to get the outline of the numbers. 

I originally cut them out in heavy paper, but decided I wanted a truly reusable set, as the numbers fade on the curb after a couple of years. Therefore I used a piece of scrap acrylic for the final version. 

Step 2: Measure the curb for the template bend

Back at home I used the cardboard version to verify position, and also measured the angle of the curb, since the acrylic needs to conform to this angle. 


Step 3: Cut the template out of acrylic, bend it to fit the curb

Back at TechShop I used the laser cutter to cut out the letters in acrylic. After warming up the Heat Strip Bender, I transferred the angle measurement to a protractor, and set the angle of the cooling form to match the curb angle. 

I marked the bend location, heated it up and then bent it. The cooling jig allows you to hold the part at a set angle until the plastic cools and sets.  (The heat strip photo is from another project). 

Step 4: Prepare the curb and paint a base coat

Mask the curb with newspaper and masking tape.

Spray a coat (or two or three) of the gloss white spray paint. 

When it is dry, coat the base layer with the reflective coating paint.

This is a great job for kids to go through their neighborhood for part-time work. I've done it several times over the years.

I like the initiative, and think you did great with the acrylic, but this could have been more easily achieved with some cut vinyl, and would have been a fraction of the expense/time. Only takes about 5 seconds for my vinyl cutter to do a cut like that.

But, I also understand having access to machines but no projects use them for... I often build/make things because I can, not because I need to.

Great job on the instructable!
