Tool for vibrating concrete? (DIY?)
So I've been thinking of making some homemade concrete stuff with different molds I plan on making.
Since I'm not a big expert on concrete and such I've been reading all over the Internet for how-to guides and what not.
And something that seems to be a really good idea is to use a tool to vibrate out the bubbles and air pockets from the molds before they set... and so far I've not found any instructable here on how to make such a tool ( because it's a bit expensive to buy one, and hey.. why not make it myself)
So my question is simply if any one know of a good idea of such a tool, how to make one or whatever..
(maybe modifying something, making one from an electric motor?) I need ideas!
