The threads extend about 1" in from the ends on both pieces of pipe. Starting at the end of the threads on the larger pipe measure 3" down the4. Insert the smaller pipe into the short end of the larger pipe such that all of the thread of the smaller pipe sticks out. Use the marker to tra5. Now to drill some holes for the handle and to create a way to adjust the cutting size of the shredder. All the holes were drilled in the thread6. Next drill some holes into the thread on the LONG end of the larger pipe. I drilled 3 sets of holes passing through the pipe spaced about 1/2"7. Using a rotary tool with a grinding stone sharpen the long edges of the slot of the smaller pipe such that the edge slants toward the inside o8. The last part of the cylinder assembly is the handle. A two-foot-long handle gives some good leverage for cutting thicker plastic. If the handle9.
