This is a set of instructions on how to make a simple but very useful home bar top to be mounted on top of a boring existing peice of furniture. (in our case an old product display case from my buddy's co-op)
Step 1: Human Factors Test-Fitting (Sizing)
Grab some cheap bar stools off of craigslist (got 2 for $10) and put them next to your piece of furniture you want to put the bar top on. Then get a test bar top (in this case a vinyl card table) and some risers (if you need them, we used cans) and sit at the bar with a drink. Is it a good hieght? Want it to be larger, smaller? Record your favorite dimensions.
