FAST FOAM LATHE

Step 2 ROUGH CUT

Rough cut is the step where you turn the square stock into a round cylinder.

I did this using a utility knife and course sand paper (fabric backed is best for this)

Here are the basic steps:
-Turn on the drill on a low speed.
-Stand aside, If the whole rig flies apart, then try again
-If it stays together, slowly start cutting and sanding until you have a rough cylinder.

Cutting technique:
Foam is pretty soft, so start slowly. The goal is to remove the square edges without destroying the set up. With the drill running at a medium slow speed, look straight down at the spinning stock. The outer square edges will create a fuzzy blurred circle - this is what you want to remove. In the center you will see a pretty solid circle, this you want to keep. Start outside the blurred circel and slowly bring the tool in until it makes contact. It will feel like it is vibrating against the square corners. Work slowly and evenly up and down the block. I sarted with a utility knife to get off the bulk of the corners, then switched to a course sand paper. You are done when the vibrations pretty much stop. When in doubt, leave extra material on the peice it is easy to take of latter and hard to put back!
