How To Make a Boxing Spar Bar - Pro Version

DIY Boxing Spar Bar Pro

10-Step Instructions:

  1. Get a ball - basketball is best. Also get a plunger, remove the handle and tape it onto the ball with duct tape. This can be screwed onto the top of your spar bar to help dampen vibrations and for light punches.
  2. Get a pair of ball bearings roughly 1 inch internal diameter and 2 inches external diameter. You can get a 2-pack of the exact bearings that I use on Amazon US here: https://amzn.to/34eLo7r or from Bunnings in Australia: https://www.bunnings.com.au/richmond-47-x-25-x-12mm-rubber-sealed-precision-ball-bearing-pack-of-2_p0103240
  3. Get a PVC pipe Tee or Cross junction into which your ball bearings will fit. Size will depend on the size of your ball bearings - for the bearings above, I'm using a 40mm Cross junction which has an internal diameter of roughly 48.3mm (eBay: https://ebay.us/ld0S6e or Bunnings link: https://www.bunnings.com.au/holman-40mm-press-pvc-plain-tee_p3142376). Tape around each ball bearing to ensure a tight fit into the Tee or Cross junction. That is your spinner!
  4. Get an arm-length of PVC pipe that will fit into your Tee or Cross joint. Here's the exact one from Bunnings: https://www.bunnings.com.au/holman-40mm-x-1m-class-12-press-pvc-pipe_p4750050 or on eBay: https://www.ebay.com/itm/Holman-40mm-x-1m-PVC-DWV-Pipe/224070397029?hash=item342ba2ec65:g:WhkAAOSwL3FfA14W
  5. Get a 1/2 inch galvanised steel pipe roughly chin height for your mast and a corresponding galvanised flange.
  6. Get a 2 foot long/wide MDF board and attach the galvanised flange two inches from one side. Screw your galvanised pipe into the flange. You'll need 4 thick, short screws to fix the flange onto your board - these screws on Amazon US are ideal: https://amzn.to/3gCO82H. 
  7. Tape around the top of your galvanised pipe where the spinner will sit, ensuring a snug fit. Add an extra layer of tape just below the bottom of the spinner to stop it from moving down.
  8. Attach your PVC arm to the spinner. Secure it by drilling a small hole through the top (through both the joint and the arm) and insert a pin or small nail.
  9. Get and attach a section of pool noodle on the arm using long cable ties for padding.
  10. Use a regular char to stabilise the mast/pole by strapping the mast to the back of the chair.
An alternative to using a chair is to make a stabilisation support system - this is a more complex build component that is only available in my Fighter DIY eBook. The book also includes a link to a hidden video that shows you how to make the stabilisation support system.

      Hi Christian, I just updated the instructions with a few more details on the Cross joint and PVC pipe. The PVC joint I used that fits the bearings is a 40mm joint (actual internal diameter is 48.3mm). It's sold through our local Bunnings store - https://www.bunnings.com.au/holman-40mm-press-pvc-plain-tee_p3142376. I have also found these on eBay: https://ebay.us/ld0S6e. Here it is on the actual manufacturer's website: https://www.holmanindustries.com.au/product/pvc-pressure-tee/ (select the 40mm one). Hope you're able to get it.

How To Make a Boxing Cobra Punching Bag Using the Kewlus Spring

Image
Intro Make your own Cobra Punching Bag at home that is faster than some of the top brands on the market at just a fraction of the cost. To make it super easy I designed and produced a custom spring specifically for this purpose. I made it so that you can simply screw it onto a 3/4 inch galvanised steel pipe. If you have any questions please put them in the comments below and I'll respond as soon as I can. Also please share your thoughts and experience with others here if you make one. Items You'll Need: Kewlus Spring (KS9) - purchase here:  https://kewlus.com/products/kewlus-spring-v1 Base pipe: galvanised  3/4 inch pipe  (1.05 inches outer diameter) the length of roughly half your height. I used a 3 foot long pipe for my height (I'm 6ft tall). The 3/4 inch pipe has an outer diameter that is 1.05 inches. The spring is designed to fit perfectly onto this pipe. You can also combine sections of pipe using a coupling , for example 2ft section and 1ft section to allow reduction

How To Make a Free-Standing Punching Bag

Image
10-Step Instructions: Get 13 pool noodles (for a 6 foot tall punching bag), a roll of cheap packing tape and a roll of cheap cling wrap (or two). For your pole get a one inch wide PVC pipe - roughly 6 foot long. For your platform get an MDF (particle) board at least 2 foot wide and 1/2 inch thick. Alternatively if you don't want to make the base, you can simply use an umbrella base such as this one from Amazon:  https://amzn.to/3nY3J19 . For mounting your pole, get a one inch galvanised steel pipe roughly one foot long and a flange to mount it. You'll also need 4 thick, short screws to fix the flange onto your board - these are ideal: https://amzn.to/3gCO82H . Note, if you want to make your punching bag more rigid, use a two foot galvanised pipe. For fixing your PVC pipe onto your galvanised pipe you will also need a one inch hose clamp. Setup your platform and pole: screw the flange onto one end of your board; insert the galvanised pipe into one end of the PVC pipe and lock
