Animated Jack-O-Lantern

Step 3 Prepare the Frame

This is a simple step, Drill the holes where they are needed.

The size of drill bit I used is a 9/64" bit, the size recommended by my tap set for an 8NC32 thread.

The first set of holes is for the Flexinol, one on the overhang and one along the bottom channel along the vertical line with it, but more toward the top of the channel bar.

Now you need holes to guide the fishing wire to the front. The first hole is needed along the bottom bar, lower in the channel to avoid rubbing the Flexinol anchor and switch later. The last guide hole is needed in the lower front corner, on the bottom channel.

The Final hole for this step is the switch hole. It should be placed along the bottom bar somewhere in the middle away from the other holes. It should also be drilled near the top to avoid the fishing line.

All of the holes in this step should be tapped using a 8 NC 32 thread size. If you don't have a tap, you will need to get some nuts to fit your threaded rod, and use a slightly larger drill bit.
