  • Tank Trap - seeking plans/advice

    I want to make a tank trap out of wood to practice with in my backyard, therefore it doesn't need to be portable. Should be pretty simple to make, but I do not have measurements. Does anyone have dimensions or plans?

    I used 6' 4x4's for mine, knocked the sharp edge off with the router. Used carriage bolts to hold it together, I didn't crank the bolts down leaving it slightly wobbly. I made a big X, then added the third piece.

      That is essentially all there is to it unless you want it more perfect (not necessary really). If you want to lay it out first, measure to the center of the 4x4 lengthwise and draw a line edge-to-edge. Them mark for drilling 1-5/8" from one side of that line. Drill through. Turn 4x4 over so that you can mark and drill another hole 1-5/8" on the other side of that line, but on the adjacent side. You will now have two drilled through holes that are 3-1/2" apart, each 1-5/8" from the center of the board and perpendicular to each other.

      Pre-drill all three 4x4s that way. I then used 8" long hex head bolts, two washers each and a nylock nut to assemble them together. I did tighten them up quite a bit, since mine was assembled at our club and gets quite a bit of use. Therefore it gets loose enough through use.

      Oh, and I used 8'x4"x4"s.

        Thanks for the info. So approximately how high is the point where the three 4x4's cross?

          Excellent. I never even considered having it wobbly, I appreciate the thoughts.

            If your question is what height is the crossing point after assembly, I would say it is about 3 to 3-1/2 feet where you can rest your weapon in the crease. I would measure it, but it is in the field at our club and I won't be there for a couple weeks.

              Oh thank goodness. When I saw the thread title I thought it was a prepper. It sounds like you're asking about the Czech "hedgehog" style of tank obstacle.

              I was was going to refer you to the Anti-Armor FM for schematics on tank ditches, abatis, log hurdles, etc. of course a lot of those work best if you've got some anti tank guided missiles or combined arms.

                  That's too funny. My neighbors would know I completely lost my mind if my property had tank traps around the perimeter.
