  1. HI XueMing,

    What gauge of galvanized pipe did you use? I am assuming schedule 40 but wanted to check. Can you provide details on your pedestrian door (hinges, attachments and cross supports)? I was doing some calculations for a 15 foot gate (10 foot opening) and with wood, pipe and track, I am figuring my gate will weigh about 700 pounds, assumes schedule 40 pipe and 2×6 wood fencing. This is why I want to know what size pipe you used.

    Nice job with your project – Thanks


    1. Hi JC,

      Thanks for visiting my post. I believe I used gauge 14 pipe. You should be able to find a table converting the schedule to gauge. I didn’t put too much thoughts into the pedestrian door. Hinges were re-cycled from its predecessor. Other details should be quite straightforward from my post photos. Yes, the gate will be heavy, so make sure the cross support for the galvanized pipe is correctly installed. If everything is done correctly, the gate should hold up well. Mine has been up and running for almost 5 years without any glitches.

      Good luck!

  2. I’m looking at bulding something similar for a camper parking access. Since it wouldn’t be used every day, I’m not sure I need the motorized opener – how hard is it to open/close your gate manually?

  3. That is one well executed project, and has provided some much needed inspiration. Thankyou and we’ll done.

  4. Looks amazing! I’m research I to try something similar myself.

    Curious how you powered this gate? Do you have to hire an electrician to properly wire it and bury the cable to the house?

    Thanks !!

  5. Great job, I really like your design. It’s been approximately 2 years since the date of this posting and your build. Have you had to make any repairs or modifications to keep the gate running smooth. I have double wood swing gates as you did and your blog will be extremely helpful.

    1. Thanks for visiting my blog. Yes, it’s been 2 years and I’m proud to report that the gate has been operating without any glitches!

  6. Some helpful notes here. Fantastic. We’re at 75% of the legwork done. I’m a general contractor that is more familiar with the materials. a) Have a concrete company come to pour your holes $300 max. If you need to build a curb around posts go to Lowe’s and ask for Sono tube. Careful not to pour too close to gate stop location. Guys at Lowe’s will tell you what to do. Any extra concrete pour into 4″ deep pancakes straight on the ground, No need to form. make large grooves in pancakes 3″ deep at 110-20 min. Break up with sledge in 6-12 hours while still 50% soft. b) lease an ele chisel for holes with extension for hard soil/rock. Good for back/hands too. c) Have welder build on site or deliver what he builds at his shop, $80-110 per hour, most welders. He’ll need to visit to make that decision. Probably 2-4 hours work but stay with him as a helper. Only do what he says if anything. Look at some of his work around town. A lot of shops do mobile work. Taking picts with some drawings to them, a must. d) Ele can be temp until you have ele power installed at operator. Building Code is 12 to 16″ deep, sometimes less. Get 2″ pvc min and run temp (with extension cord) from house if not over 100′. Less than 2 is too hard to pull, and do in 20′ sections. You should use 14 gauge, 12 if you have to. Buy a 100′ extension cord 22-$50 new. If you don’t need ex cord later, sell on Craig’s 1/2 what you paid etc. When you do final ele, tie your wire to extension cord and pull through. ABSOLUTELY, DO NOT bury extension cord straight into ground!!! You’ll cut it later taking it out. If you don’t do ele work get electrician for final, 50-100 per hr. Most won’t risk their license doing w/o permit. Unlicensed only if you know him and still, absolutely code, no cheating.

    1. How it come out am trying to make one the. Same size any info or tips would be greatly appreciated

  7. A most impressive home engineering project and an enjoyable, informative read. Well done Sir.
