In this Instructable I will show you how I made a Numbers House sign using a CNC Router.
I have a old set of metal numbers on the side of my house, so I thought I could spruce it up a bit. By making a House sign out of wood. Since I now have a CNC, I can make a professional looking sign, this is what I came up with.
I have included the crv files and the dxf file for those who are interested.
Note I am not a expert at this, please check all toolpaths and cutters before creating toolpaths for CNC

Step 1: Items Needed
CNC Router ( I am using the Xcarve)
Cam and Cad Program ( I am using Aspire)
Wood ( I am using a piece of Poplar 16 3/4" x 11 1/2" x 25/32")
1/4" Downcut Endmill Bit
90 * V-Bit
Stain ( I used Minwax Dark Walnut and Prestain wood conditioner)
Black Craft Paint
Small paint brush
Paint Brush or Foam brush
Minwax Clear Gloss Polyurethane
Step 2: Design
I open Aspire and design the layout of the sign.
I first draw a ellipse 9" x 4.5", I then added a rectangle 11" x 6" .
Put some 1 3/4" circles in each corner of the square, then took the Interactive vector trim to cut notches in the corners.
I then added another ellipse 12" x 7". Again I used the Interactive vector trim tool, cut vectors until I had the shaped that I was looking for. Then I highlighted the outer vector, selected the tool, offset vectors, inwards .5" and created a new vector, that looks like the outer vector.
I then added the numbers, using Times new Roman and 2.5".
Step 3: Toolpath
I then setup the toolpaths, first using a 1/4" downcut endmill bit, to cut the inner flat areas. Then I choose a 90* V-Bit to finish the inner cuts, plus carve the numbers.I cut both of these at a depth of 1/4" deep.
I Preview all toolpaths, before exporting them to gcode.
Step 4: CNC
Place your stock in the CNC Router and fasten down. I clamp mine down.
Install a 1/4" Endmill in the router and carve the flat areas out first.
Step 5: V-Carve
Now I install a 90* V-Bit, we then finish carving the inner shape and then carve the numbers.
Step 6: Cutout
Now we cut the part out by using a 1/4" Downcut Endmill bit.
Step 7: Paint
I painted the numbers and area where I used the V-bit, using Black Craft Paint.
Let the paint dry overnight.
Step 8: Sand and Clean
I sanded the flat areas of the piece using 220 grit sandpaper, then blew off with air hose and wiped off real good.
Step 9: Apply Prestain and Stain
I applied Minwax Prestain wood conditioner, let set for a few minutes, then applied Minwax Dark Walnut Stain.
After letting stain set for about 15 minutes, I wiped off with a clean rag.
Then I let the stain dry overnight.
Step 10: Apply Clear Coat
Now I sprayed Minwax Clear Gloss Polyurethane and let it dry for 24 hours.
Step 11: Install
Now after the Clear finish has dried, hang the House sign onto the side of your house and enjoy your hard work.
