Step 5 Cutting the Groove

I usually cut both marked top and bottom at one time--if building multiple houses you can cut four of these sheets at one time. It is best to clamp the sheets securely before cutting. I drill start and stop holes at the end of each line with a 1/4" bit and then proceed to cut out the long channels with the rotozip or craftsman equivalent rotary drill with the 1/8" bit. This will form the tight slot that will hold the wall pieces in place. It takes a little practice to get a smooth cut but with moving slowly the line will be quite steady. This is an amazing piece of technology and useful for a lot of other projects.
