I received several emails and a couple of replies on my last post asking about the vibrating table I made for casting blanks.
The table is made out of 3/8" thick aluminum, but wood would work just as well. It 13 1/2" square and 4" tall. Large enough so I can sit the pressure pot or vacuum canister on it.
To keep stuff from vibrating off the table I kept the top about a 1/4" down from the sides.
The top floats on 8 small springs so only the top vibrates. This keeps the base from moving around the bench and it also makes it a lot quieter.
For vibration I used an old chair massager that I picked up at a thrift store for a couple bucks. It does a great job. It has 6 vibrators which run in 3 zones, two vibrators per zone. Each zone has a setting for a pulse or constant vib, and 3 different strength settings, high, medium and low. The vibrators are just hot glued to the bottom of the table top and the controller is stuck to the side with velcro. I was worried about the hot glue holding but so far so good.
To keep the top in place so it doesn't slide around and vibrate against the side I drilled a 1/4" deep hole into a piece of maple for each spring to fit into.
I originally planned on using an old random orbital sander, which I think would do a good job if ya can't find a massager.
I had most of the material kicking around the shop so the whole thing cost me about 15 bucks to make .. Good and cheap
