Large Jacob's Ladder

Step 5 Top Support and Spacing

This will hold the copper pipes at a constant spacing. Take the other two 6" acrylic rods and rubber band them together. Put them near the top of the copper pipes to hold them at the spacing you want. Change the spacing around and see what works best. Always make sure the transformer in unplugged when adjusting anything. Once you find the right spacing, make shallow notches in the acrylic where the pipes should go (see the pic for better explanation).
