Build an A-frame for a Slackline Part 1

Step by step instructions on building an A-frame system to support slacklines without using trees. There are other patterns out there, but we feel that this pattern is the best since it offers a full sheet of plywood support which increases the length of line that it can work for as well as increasing the abuse it can take. Some of the tools and techniques are optional, but regardless of your method expect these to take 3-6 hours for someone with limited woodworking experience to make.
