Your look is always key so planning your build is important. Do you want the more basic iron look or are you looking for a long bar short bar look? All these are questions for yourself before you just start building.
Preparing your Parts
Section: Cutting To Size
Let's cut the materials down to size and drill some holes.
4" PVC Sch 40 DWV Plain End Cellular Core Pipe
Using a miter saw, cut down the PVC pipe into lengths of 21.5mm or 0.85in. When you are cutting these you may want to consider a wood guide on the saw so the pieces do not get jammed behind the fence during the cut.
1/2" PVC Pipe
With each 10 foot length, cut them into 3 pieces. If your PVC pipe has a flare at one end, cut the flare off first and then cut into 3 pieces. Each piece should be 38" to 40" long.
(Optional) Using some scrap PVC cut two templates to use later for marking the plywood for drilling. Cut a 127mm and 138mm PVC pipe. Another option is using a picket master tool. If you are doing a large amount of fencing the picket master tool might be worth the time savings.
First we are going to need to cut strips of plywood and then we are going to use a forester bit to drill the holes that the PVC will eventually slide through.
Cutting: Using the long edge of the plywood, cut 35mm or 1-3/8" strips of wood. Each section of the fence will take three 8 foot strips of wood to make.
Marking for Drilling: We need to first mark the plywood for drilling. Using the 127mm measuring template, from the one end of the strip of plywood mark the initial point. Then using the 138mm measuring template, measure and mark each additional center point using the last mark as the starting point. There should be 16 total marks that we will use for drilling. At the opposite end from where you started marking, use the 127mm template to mark a 17th point. This last mark will be where you will trim down the strips to make an even spacing on both ends. Now, with the first 16 marks you made, find the center of the board so we know where to start drilling.
Drilling: Stack the 3 strips of plywood and clamp them down. Make sure to apply clamps where needed to keep the boards aligned through the length of the strips. Using the 7/8" forester bit, drill your center points through the 3 layers of plywood. Make sure to go straight through the 3 layers, two of the sides have very little room for error. It is recommended to use a portable drill guide to ensure you drill straight through all 3 layers.
