@@Kewlus Hey mate, i just ordered the spring from ya last 4digits of my Order number -1461 I hope I get it soon lol it says 2-3days shipping to the USA. Thanks brother
Thank you brother 👍 Yes it’s shipping from Canada to you so yeah just 2-3 days. You’ll get an email with tracking details as soon as it ships which will be today or tomorrow 👌
Yours was the very first order fulfilled from a warehouse in the US. Enjoy! This is how I intend it to be for all future shipments. I'm in the process of contracting warehouses in North America and Europe for speedy deliveries. The Kewlus Spring PRO (KS12PRO) is coming!
Hello Kewlus, Nice video Don’t you think that something like a wooden self made box filled with sand or water could be the bottom, which you can connect the pipe onto? It would be nice with another solution, than water bottles, maybe out of aesthetic reasons. Hope you can do a video with another idea to a bottom.
Yes, I will be doing more with the base ideas. I'm currently working on a prototype base using suction cups - it's awesome, and I can't wait to reveal it. It would be perfect for using in a garage on concrete floor or on any tiled or wood floor.
Just bought the spring! Thanks so much for these videos ....I can't justify paying 300+ for a cobra bag but thanks to u im gonna have one please keep these videos coming
I’ve been using mine for months. One advantage is that it will never burst or go flat. I’ve had that many speed balls break on me, but never the pool noodle one 👍
Hey reedy I don’t know if you can help with this but are there any tips for getting the spring off I got it on the pvc and 3/4 inch pipe but it won’t come off
I use a lever like a flat screwdriver to slowly leverage it upward and off the 3/4 steel pipe. With the PVC, turn it clockwise as you pull it out. It’s very difficult to get it off.
It's usually better to get a concrete one from a local store because they are heavy and you're mostly paying for the delivery cost. If you have to order one, this one is not too bad and I've used it myself: amzn.to/33xUf44
More stock is due in the US warehouse. Due to the Christmas rush and COVID, there have been delays. Please subscribe on Kewlus.com (footer) and I'll notify all subscribers when stock becomes available.
@@SeanRafael good luck finding the correct spring though. From what I'm seeing online their out of stock or are having shipping problems. I've bought over 10 springs and none of them are what I'm looking for. So If you dont want to wait and go through weeks or months of trial and error, I would just suggest you buy this guys spring when its available. Lucky for me I had a spring laying around that seems to be ok for now but I might honestly just purchase Ryan Garcias Fierce Reflex bag and call it a day. If it ever breaks it's easy to fix. I just dont wanna wait months for these springs to come through. I just hope that for $500ish the fierce reflex bag is worth it. If only I could find the right damn springs.. also if I purchase Fierce Reflex bag elite version for $500ish, I'll finally be able to see what spring it is that they use, this way I can get my hands on more springs and make it and sell the unit for half of what they charge for the elite version. $500 is way to expensive tbh.. I'll prolly buy it and return it just to get a feel of the spring and what they made it with.
@@bmlaforge I’m using the power twister in his other vid at the moment with a galvanizes pip I had a custom whole saw through and cut off to perfect size at the end
@@Kewlus is it possible that you'll ship all the parts? if yes, what the price will be. Thanks (I want the very last adjustable version that you came up with)
What is the difference between the ks2 kewlus spring and the power twister in terms of tension or maximum load? The power twister I have has a maximum load of 66lbs (30KG). Is the KS2 spring looser or tighter than my power twister?
The power twister has a different type of spring where the coils are close together. It’s not really designed for a cobra bag, although it can be used for it. The KS2 on the other hand is specifically designed to be used for a cobra bag. I can’t really say about the difference in tension as they are just different types of springs. KS2 is not rated for weight like a power twister and is not designed to be bent like one
@@Kewlus Is there anyway I can make the power twister more like the KS2 spring? I tried using the power twister for my own homemade cobra bag based on one of your videos and it doesn't oscillate the way yours does?
It’s almost impossible to take off once it’s on. Just make sure to thread it on at least an inch onto the pipe and wrap it with duct tape if you’re concerned.
Currently there is limited stock available just in US & Canada. More stock for global shipment will be available soon. I'll announce when it becomes available.
@@Kewlusawesome, I made one with a 30 kg power twister, but it's too stiff. I'm gonna try to make the top section bigger and change the target, and then probably buy one of your springs and make this model
i live in sweden onley the sprin cost me 75 dollar . its not good fore me . well i really like yore vids, i did a bad back operation so i was thinking to try this movment a am a amatuer boxer in past time . but i need to try fint a spring
No it doesn’t, but it helps to get it onto it. You can use a hose clamp to clamp it in place if it’s loose. Typically though all 3/4 inch galvanised pipes have a thread

Was going to pay £250 on one the other day then seen the video. Just bought the spring so going to give it a go. Cheers for the idea 🥊
How did it work?

Damn I dont know how you dont have more subscribers honestly its amazing i was about to buy one 250 dollars thanks man
You’re most welcome 😀👍
I am soo excited to build mine once the spring comes in!
How did it work
@@damonvilla the bag hits like a beast! dont think twice about it.
dude this man is a legend. really legend !
I made this and i have no regrets on buying the spring obviously a better choice compared to spending 300$ cad on a decent cobra bag
Awesome! Thank you for your feedback!!!
how is it? does it make too much noise? cuz i wanna make it for my apartment
I got my spring delivered yesterday and built it today. Love it already.Thanks man.
Enjoy brother! 🤙

Just bought the spring! Thanks so much for these videos ....I can't justify paying 300+ for a cobra bag but thanks to u im gonna have one please keep these videos coming
Hey it just arrived and it seems bigger than 20mm. it's 25 mm so the pipe I got is far too small
The spring has a 1 inch inner diameter and goes onto a 3/4 inch pipe (20mm pipe) which has a 1 inch outer diameter
Ah ok, I had a 20mm threaded bar and taught it would fit that. No worries I'll just get the right size thanks
Are you ever going to sell this kind of spring again? I would be interested in buying it as well.
You Are The Man.
Just ordered. Cheers
Thank you 😄
Genius stuff there. Quick question though for those of you who have been using this for awhile, just how durable is the pool noodle punching ball?
I’ve been using mine for months. One advantage is that it will never burst or go flat. I’ve had that many speed balls break on me, but never the pool noodle one 👍
@@Kewlus Good to know! My previous bag (foam based) just cracked on day and burst. I'm definitely gonna give the pool noodle a go though!
Ain't going to happen with this one that's for sure!
Dam buddy you sold out in USA. Congrats!!!
Thank you. More coming 👍
I'm broke (I'm 10) but I still watch your videos they are entertaining
Hello, I wanted to know how big the spring is? and where do i buy it?👍
It's been upgraded to the PRO Spring which you can get from kewlus.com/products/kewlus-spring-ksr12pro
Have you tried using a galvanized steel pipe instead of pvc for the top portion?
Yes but the PVC pipe keeps it light and fast. The galvanised pipe would add extra weight and slow it down.
Hey reedy I don’t know if you can help with this but are there any tips for getting the spring off I got it on the pvc and 3/4 inch pipe but it won’t come off
I use a lever like a flat screwdriver to slowly leverage it upward and off the 3/4 steel pipe. With the PVC, turn it clockwise as you pull it out. It’s very difficult to get it off.
Hey mate. Can this spring be used on the Viking Cobra Rapid Bag?
As a crazy pear please
Nice 👍🏼
I need help choosing an umbrella base. Can you send a link what you would recommend via Amazon?

Will motorcycle front fork spring work??
Not sure brother. Never tried one. The problem is how to fix it onto a mast and I don’t do welding 🤷
Is this better then the fishing rod? I want something that is close to the fierce reflex bag
This one is similar to the Fierce one. The fishing rod one has longer reach as it flexes from a lower point.
@@Kewlus how secure will the spring be ...im afraid after alot of punching it comes loose ...should I weld it? Cause I wanna hit it hard
It’s almost impossible to take off once it’s on. Just make sure to thread it on at least an inch onto the pipe and wrap it with duct tape if you’re concerned.
@@Kewlus could I shorten the spring? How tall is it?
It’s 9 inches long. You can thread if further onto the pipe to shorten the effective length thus increase the speed

I mean will metric size gal pipe you get from bunnings work or does it have to be imperial
20mm and 3/4 inch are the same pipe
