How to Make a Jig for Railing Posts
Step 1: Start with pre-cut pipe.
Step 2: Measure and locate fittings on first post only.
Step 3: Lay post horizontal, and insert two pieces of scrap pipe.
This is all that's involved in setting up your jig! From this point, duplicate
posts can be produced by unskilled labor, without further measuring, at
the rate of 20-30 posts per hour.
