How To Make a Reflex Punching Bag at Home

DIY Reflex Punching Bag

10-Step Instructions:

  1. Get a ball - soccer ball or volleyball is ideal.
  2. Get a drain plunger and good quality duct tape and tape the plunger onto the ball, ensuring not to cover the air inlet. AmazonUS: https://amzn.to/304M8eJ
  3. For the base get a 2 foot wide MDF or "particle" board.
  4. For the mast/pole, get a 1-inch diameter PVC pipe (in Australia this is referred to as 20mm; in US it’s referred to as 3/4 inch) - you'll need roughly shoulder height. AmazonUS: https://amzn.to/2XopfRy
  5. For the base you'l need a short 1/2 inch galvanised steel pipe. The length of the steel pipe should be roughly 1 foot and will dictate the speed - faster with a longer steel pipe. AmazonUS: https://amzn.to/2Xo2gpJ. You'll also need the corresponding flange to mount the pipe onto your board. Amazon US: https://amzn.to/36Tbfm8
  6. Attach the flange to one side of your board with thick, short screws. You will need to drill appropriate size pilot holes first to allow your screws to crew in easily.
  7. Attach your short galvanised steel pipe to the flange.
  8. Take your PVC pipe and make several 1 inch cuts into the pipe at one end. Place an appropriate size hose clamp over the section with the cuts and mount the PVC pipe over the short galvanised pipe, clamping the hose clamp to lock it in place.
  9. Attach your plunger with the ball to the top of your PVC pipe by inserting the handle of the plunger into the PVC pipe. Tape it in place.
  10. Place two 10 litre water containers in the middle of your board to weigh down the platform.
Good luck making it and hope you enjoy! If you have any questions feel free to ask them in the comments below.

  1. Hello Sir,
    I went to the lokal Shop to rebuild your newest version of the Cobra Bag. Unfortunately they don't have PVC pipes smaller then 70mm diameter.
    So I searched on Amazon and found this: https://www.amazon.de/16bar-Druckrohr-Meter-Kleberohr-Aussendurchmesser/dp/B07CGC1FKY/ref=mp_s_a_1_7?dchild=1&keywords=PVC+pipe&qid=1591009145&sr=8-7
    It might be on German but I hope that you can tell me if it will be enough or if it's to hard and that it won't move.

    1. In Australia this PVC pipe is referred to as a 20mm PVC pipe. In US the closest to this is a 3/4 inch PVC pipe. Basically you're looking for a PVC pipe that is roughly 1 inch in diameter. Here it is on AmazonUS: https://amzn.to/2XopfRy

  2. What is a "pressure Pipe"? Is there any difference between a pressure pipe and a normal PVC pipe? Or is that the Same?

    1. Pressure pipes are generally tougher than grey water (drain) pipes. In Australia they are a white colour as opposed to the grey colour of the drain pipes.
