This was a fun afternoon project I did while teaching my son how to use the router table to cut round layered pieces. Took a minute to figure out how to salvage the light bulbs, but it came out okay.

Interesting, Rich! What did you use to restrict the sand flow and how long did it take to figure out the right amount of sand? Thanks for sharing.

-- God bless, Candy

Candy – I actually experimented a little with that. For time’s sake I settled on a piece of plastic that I cut from the cap of a disposable water bottle. (Could have used almost anything there really) I just drilled a small hole and then tested it.

My timer is a two-minute timer. Determining the amount of sand was easy. I used table salt actually. Sand granules are not at all consistent in size. Surprisingly, table salt is … enough anyway.

So, I just made the hole in my center piece and hot glued it into that wooden ring you see there. Then I used a funnel of salt on top and a jar on bottom and let two minutes of salt pour through. When I reached two minutes I stopped it and WAH-LAH! I had two minutes worth. Putting the salt inside the lightbulbs didn’t change the timing at all. One piece of advice though – Make sure the hole you use is clean (sanded flat) on both sides or your timing will be different turned one way versus the other. I had to pull mine apart and fix that. ;)

This is a surprisingly easy build and it looks GREAT on the end table in my living room. Everyone asks about it when they see it. It looks like an antique. LOL!

I’ve always kind of wanted an hourglass. Now, thanks to you having done all the work, I may make one. This thing is beautiful, great job.
