Floating raft

These styrofoam boards are 1 inch thick, 2×4 feet in size, RM8.00 per piece.

Marking the holes, about 6 inches between them.

I drilled the hole manually by hand, using ½ inch PVC pipe.

Using pen knife, I made saw-like teeth on the pipe. Rotate the pipe slowly to get a clean cut circle.

One board done, it took around half an hour to complete it.

But it took a week to finish all these 18 boards
