CJanson has an Instructable on making your own Lightsaber – “We saw an example of someone who used regular plumbing supplies. We decided to try it but found we could improve upon if for ourselves. It requires no soldering, gluing or anything other than the following supplies and everything (except the faucet hole cover) was found in the plumbing isle of Home Depot: Pop-up Basin Drain (1 – we used plastic to save $$, but there is a selection), Drain extension tube with threads and slip nut, Slip nut and washer (1), 1 1/4″ Disposal gasket (6), 1 1/4″ Slip joint washer (6), Faucet hole cover. All supplies (except maybe the Faucet hold cover) can be found in the plumbing isle of Home Depot.” – Link.
