[@Kewlus]

Thank you all for your support! I've turned my channel into a global brand of DIY kits: kewlus.com, including World's First Modular Cobra Bag!

[@gerrytaroreh4043]

U are such a creative person. As i thought there are always people like u on youtube😁.. thanks for sharing anyway.

[@Kewlus]

You’re most welcome 🙏

[@theharvester97]

LOVE WHAT YOU ARE DOING, not only does your stuff seem to be equal or greater quality than store bought equipment, it’s for a fraction of the price! I always wanted a spar bar to mess around with but they are $400 too much! Gunna try your builds soon, so creative and so helpful man keep it up! (Would just suggest for extra help that you could list every single item with exact measurements used in the build, just so we can replicate your quality exactly)

[@Kewlus]

Thank you! 😁👍 I’m planning to put every build as a post on my website including a list of items in each build. You’ll love the final spar bar build! Stay tuned.

I don’t click the bell for anyone I subscribe too but you make such helpful videos, imma click it on cause it helps you out.

[@Kewlus]

Thank you brother

[@znebrem]

I put this one together today. Works pretty well, just need to shorten it a bit and I think your plunger is smaller so yours is smoother. My plunger has some wobble in it. To be continued.

[@Kewlus]

That's awesome! Well done bro! In my latest versions I actually cut away most of the rubber part of the plunger so that it sits flush on the ball surface and I tape it in place just like that. I then tape the funnel over the top to the ball and the PVC pipe - this ensures there's no wobble and a double connection between the ball and the PVC pipe. This week I'm posting a minor upgrade that you might like, so stay tuned bro!

@@Kewlus do you have a patreon?

[@Kewlus]

Patreon? What’s that?

[@znebrem]

@@Kewlus a lot of youtubers have them. People can go donate money to channels that they like. I donate 1 dollar a month to a channel called Mexican martial arts. One dollar is nothing for one guy but when 20,000 people give a dollar a month, they support their channel to keep making videos

[@Kewlus]

Thanks brother - you helped me discover a couple of new things today, including the fact that I can have links on my channel!!!! I'll have to check out this Patreon thing and set up a page! Thanks heaps!

[@joeking2174]

Very nicely done very creative but I dont understand how to keep the ball on the plunger without it flying off.... I get tape it but I had to tape around the whole ball to get it to stay without flying off

[@Kewlus]

The tape I used is super sticky

Could you build a core stik machine on plate form it’s for boxing for striking

[@ppenguinsjb1912]

I really don't see how that ball doesn't come loose though seeing how it's just taped onto a plunger although yes the movement is below but you were still punching it pretty hard LOL

[@Kewlus]

I told it to “stay” and it is simply obeying me. It knows that if it doesn’t then I’ll start kicking it

[@smilingrat5143]

A bit late but would it make a difference just putting a 15mm pvc pipe straight into the flange. Thanks

[@Kewlus]

That’s not likely to work

[@jonahling5126]

Can the plunger suits a basketball? Because I only have a basketball at home

[@Kewlus]

Yes here’s one I made with a basketball: kzbin.info/www/bejne/jqfIf5Vsnap8ZqM

Good job mate another great idea and great video, keep it up 👍🥊

Thank you Leon! Will shoutout if I need help. Appreciate your offer of help 😀👌

[@dumtakadumtaka]

Whats the name of the metal parts on the bottom, they are plomery stuff?

[@Kewlus]

Galvanised steel pipe and flange

[@hixtershin5819]

What is the size of pipe and flange? And galvanized pipe top thanks u.

[@Kewlus]

1/2 inch flange and galvanised pipe. PVC pipe to fit over the galvanised one

[@Kewlus]

Also check the details on fightetdiy.com and ask for more details there if you’re still unsure 👌

[@hafizhalfaruqi7402]

Where did you buy the flange and metal pipe?

[@Kewlus]

From a local hardware store, Bunnings

[@VegitosTrainer]

Hey man which screws and what size did you use for your flange to mdf board? Thanks

[@Kewlus]

The screws are 14G x 25mm. I'm just publishing a new video where I show the screws in the original packet. Stay tuned.

[@airgunyt9896]

what is the thing on the bottom that makes it springy?

[@Kewlus]

PVC pipe

[@austinlai932]

What size hose clamp is it? 3/4 inch? I’m guessing?

[@Kewlus]

1.3 - 1.7 inches diameter. More details here: kewlus.com/blogs/diy/how-to-make-pro-cobra-punching-bag

[@austinlai932]

@@Kewlus also do I need schedule 40 pvc pipe or will normal pvc pipe work

[@Kewlus]

As long as the diameter is 27mm or slightly less

[@austinlai932]

@@Kewlus so it can be normal?

[@Kewlus]

Yes but there are a few different varieties of “normal “ so just make sure it’s less than 27mm outer diameter or the spring may not fit

[@xaviercoachlee6908]

Is it ok i use a metal funnel? Other any option for funnels? And what kind of tape do you use for the ball?

[@Kewlus]

I use Gorilla duct tape. The pipe needs to be a PVC pipe to be able to flex

[@josephavelino1555]

Wow ur back 🙂

[@Kewlus]

Sure am! 😁

[@Brandondp300]

Hey so I tried making this but I have 1 problem. The screws keep coming out of the mdf board. Has anyone else experienced this if so how did you resolve the issue?

[@Kewlus]

You could maybe try using bolts?

[@Brandondp300]

@@Kewlus I'll give that a shot! 1 more question. Are the screws supposed to be long enough to go through the other side of the board?

[@Kewlus]

Mine went through just a millimeter so I had to file them off. Ideally you need find thick, short ones or use a thicker board

[@Brandondp300]

Yeah I think the problem with mine was the screws weren't long enough. How thick is the board that you are using?

[@Kewlus]

16mm

[@kingofmix2591]

Excellent! Waht size is the PVC ?

[@Kewlus]

It’s a 1 inch pipe

@@Kewlus ok.thank you

[@jordiasensio5264]

What material is the tube or what is it called?

[@Kewlus]

It's called a PVC pipe - common plumbing pipe made from a polymer plastic. I use a one inch diameter pipe in this build.

What name of all materials

[@Kewlus]

I'm putting together complete written instructions with all the details. Stay tuned!

[@poetic_pugilist]

not all hero wear cap

[@OsmiumFist]

You made a blue by using the handle of the toilet plunger. It's way too stiff. I only used the head of the plunger and inserted into 20 mm PVC which is much more flexible. You could clamp it but mine is fine and I've beaten mine like the ex-wife. Any rigid point will eventually snap as I found out. I used a lot of tape as well. It should be fine now if you inserted the plunger all the way in the PVC.

[@Kewlus]

It actually broke at the rubber section of the plunger which was strange. In the heavyweight version I’m probably not going to use a plunger.

[@joeking2174]

I dont understand how to keep the ball on?? I used tape but it still comes off I had to tape the whole volley ball to keep it on which makes it all sticky after hitting it enough the tape rolls back

[@Kewlus]

Ok let’s figure this out! As a consumer you’d pay around 50$USD including shipping? If everything was done and you just had to screw in the flange and find something to weigh the platform down - would that do it?
