DIY PVC Bow 75+ Lb Draw!




This is a powerful pvc bow that has a draw weight of 75+ lbs. Some of the stuff needed is optional but to ensure durability and power I recommend using everything in this instructible. **I am not responsible for any damage or injury done to property or your self**

1" pvc (5 ft)
1/2" pvc (5 ft)
2 fiberglass sign posts
Lost of tape
Arrows (optional)
7 ft of string
Broadhead (optional)

Step 1: Fiberglass Reinforcement

Take your fiberglass sign markers. Amd measure the to the same size as the 1/2 pvc tube then force inside. Next take anything to fill the hole so the fiberglass doesn't riddle around then apply glue. This is the easiest part of the build. But your measurements must be precise.

Step 2: Fiberglass Spine Placed in Body

Next take the 1/2 pvc with fiberglass inside and make a tire looking thing on both ends. This is so when you force the 1/2 pvc In to the 1" pvc, it is a nice snug fit. Make sure it is tight enough it doesn't move but not to tight that it can't come back out. Make sure there is tape on the ends so that the fiberglass does not fall out. (even though it will be really hard for it to without it)

Step 3: Cutting Notch for String

Take a saw of any kind and cut two slits next to each other and make them as close to the end as possible but they CANNOT CUT into the 1/2" pvc!!! that will weaken your bow. Next take one end and cut the top half you sawed into. Sand all of the places you cut to ensure your string doesn't get snagged.

Step 4: Stringing the Bow

Tie a normal double knot on the end that hasn't been cut on the side. That is your permanent knot and should only be removed for changing of string. Make a move able knot for the other end. This will be on the other side so u can unstring and string the bow for longevity and power reserve.

Step 5: Adding More Fiberglass

I have this fiberglass Laying around from another bow. This is added to the handle to ensure the pvc doesn't snap and so it retains it's shape when not in use. (if you don't have any flat fiberglass I would recommend buying another sign markers and cut it in half then apply to handle)

Step 6: Arrow Rest

The arrow rest is a toothbrush. This allows the vains to easily slide through with minimal damage. Also just made a flip down arrow rest that works really well!

I had a lot of fun making this bow as this is first. Thanks to pucksurfer as he gave me the idea to make a step by step and share with everyone this wonderful bow. I will have more on shooting it later as this one is a little different than my other one. Also after you have made the bow leave it overnight strung. This will give it it's natural bow and make it easier to string. After that one night of leaving it strung do not leave it that way. Thanks for reading and have a blessed day and good luck!

Step 7: After 2 Weeks!

After 2 gruling weeks... (even though this has only been up for a few days, I had put this instructible up later) I have managed to push it to the limits and figure out what it can and cannot do. Overall this is a great weapon for survival situation and can easily kill small and medium game. I will go over pros and cons of this deadly weapon.

light, and easy to carry only about 5 lb.

Quiet, this is a crazy quiet bow, I don't know if it's the pvc that dampens the sound or what but it is really quiet.

Accurate, out to about 50 yds. Past that you can still hit but get arrow drift.

Unstringable, (if that's a word??) but can be unstrung to save power!

Heavy draw (could go either way depends on the archer)

Cheap to make only $12

Can shoot 180 fps with 500 grain arrows.

Weather proof because of the plastic pvc.

BIG, really tall... That's all i got to say about that.

Draw weight could be too heavy

On small game over penertration almost always happens... Even with rubber blunts.

Not a toy

Makes for storing it a hassle because like I said it's to big


All in all I can't be more than happy with this bow. To be made out of pvc it is a really powerful weapon. I have killed 5 rabbits over the course of the two weeks (farmer request) and I used the rubber blunts and g5 sgh. The g5 penetrated all the way through 3 rabbits. Then I tried the rubber blunts and they too penetrated all the way through. I was shooting from a distance of about 15 feet for all of them and penetration through the animal happened with all broadhead,amy suggestions?? I hunt for food and the farmer allows me to keep the rabbits... For all u hunter haters lol, but anyways a really powerful weapon and pretty accurate. I would definitely love to try this on larger game but that isn't till next time. Please ask any questions, I will be happy to answer them, and don't mind my grammar. And as always stay safe and be rigorous!!!

you did a fantastic job here, both the bow and the instrucable. Some things to remind to add in your instructions that I recommend are, that the bow string will be roughly 3inches shorter than the full measure of the bow, and that one should not use great stuff or sand to fill the pvc.

Great stuff not only will take almost 24 hours to properly cure, but even worse will start to detieriate and powderize inside the bow the longer and more frequently you shoot.

Sand will inevitably either settle after extended periods of storage,and if swish all around inside the bow nocking reliability and precision out of the picture.

Almost forgot something, the distance between the bow's body and the string should be in the ball park of 7 inches apart. Less and more by too much will drastically change the poundage and precision.

Do not take this reply as rude, rather as a compliment. It was your instuctable to motivated me to finally try making a PVC bow. I started by making a bow with 2 markers and 1/2 inch pvc at 6 feet, with paracord for string. It was thrilling to put it all together and then take her out to the range and test. That, my first bow was fun, but wouldn't be able to kill anything even at 5 yards. However, for teaching youths, or new comers it was fun.

Then, today, I picked up some more supplies. Bringing all supplies invested to a grand total of about 28 dollars. Definately going to be the cheapest bow I have had the pleasure of atuning.

I used 4 driveway markers, 2 @ 6' long and 2' @ 4' long.

1" PVC @ 6' long

2 pieces of 1/2" PVC 3" long

2 end caps

electrical tape

around 67" of Paracord

Final result: one 6 foot long, 43 and half pound pull, PVC longbow.

I am still working on how to quiet her down after release and how to strengthen the first bow to something hunting worthy without stepping up to 1 inch pipe. The research and construction is exileriating. The rewards to come from bringing her out into the field to continue to teach and hunt, priceless.

Thank you.God Bless,

I've been looking to build one with my my dad, but didn't know how to

So i started searching on how to make one that I could use to hunt with, and shoot targets with and I stumbled upon this just recently. Good info, haven't got around to making one yet but plan to in the future. Thanks for the info though! ?

Looks cool must try this, but a word of caution, while handling that fibreglass wear gloves AND EYE PROTECTION, that stuff splinters and is evil

Would it not be better to use a heat gun to flatten out the two ends after you sleeve the 1/2 pvc inside the 1"?

Dude, everybody chill. This guy did great. I think that if you are going to criticize him, then at least make one yourself and see how hard it is. INSULTING HIM IS NOT DOING ANYBODY ANY GOOD
