This a a quick video showing you how to set up your Amish leg table. It's really straight forward and can be done by one person, though they have to be strong enough to tip the table on it's side and then legs by themselves.
The quick over view is that each leg has 2 bolts with washers and 1/2 inch nuts. You'll need a deep socket wrench because the bolts are fairly long.
THe first step is to remove the nuts a washers
Second slide the bolts into the holes at the coner of the table
Slide the washers on and then hand tighten each nut.
Once each has been hand tightened cinch them down with the wrench. Make sure not to over tighten them as this can begin to back the bolt out.
