That's an awesome perspective...

Be4 u take it , pick a hammer and test it .

"Also, this hammer "

If it works out, please do report. Seems like there are less and less PVC pipes that aren't brittle being sold, and I can't even find fitting PVC pipes around here, everything is too thin-walled :(

No, its elasticity is determined by the plasticisers used to modify its characteristics in manufacture. If anything it will become more brittle if thermally cycled.

@@mariemccann5895 I guess the question then is, are there any compounds that could be purchased easily that would act as plasticisers and whether applying those topically/submerging the pipe (and presumably letting it "cure" for a while to get rid of the excess) could be the way to go

You probably didn't heat it enough

How are you?

Enjoyed watching this build. Came on your channel several years ago and haven't seen you for quite a while. Brings back memories of making bows and arrows nearly 75 years ago as a youngster, pre pre PVC🙃

Facts

Awesome! Thank you for watching!

Awesome! I'm glad you were able to make one!

I been working a lot with Tesa tapes for a while and I absolutely agree with you. Btw yes it's possible to make the bow even stronger, with a fine method you can even use 2 pipes at the same time and make it a compound bow. With that you can easily reach 55-60 pounds if it's a well made one (had one).

Sim,um interior do outro. ​@@sesdartesesdartino3882

You're welcome! Thank you for watching!

Glad you enjoyed it

Thank you for watching!

It broke on me and it doesn't reform when you heat it back. Pex works alright as a core as it's more flexible

You are very welcome! Thank you for building along with me! I'm impressed with you freehanding your first bow!

@@BackyardBowyer Thank you, Nick! It was a lot of fun. I made a flattening jig for the next few bows & it saved me a lot of time. The flattened horse bow with wood siyahs is my favorite so far. I will be trying out some more of your builds soon.

So the fabled PVC pipes that work still exist, then?

@@MrCh0o yes. They still shoot fine now. I made a several from Nick’s tutorial vids

@@J6rish Were you using the 1 inch, schedule 40/80 pipes? I'm determined to find the ones that would work one day, but I'm pretty sure all the stuff available locally is too thin-walled...

They take a set, which is why I add the recurves as well as the reflex. This results in a bow that still has about 1" of net reflex (the tips push the string forward so the limbs are able to take a set without taking a permanent deflex of what would be considered a negative set. It takes about 30-50 arrows until the bow settles down. I'll sometimes keep the bow strung for a week to force the set. Such bows tend to be very forgiving and stable, while slightly slower than bows that have more reflex.

The main reasons for embrittlement seem to be the manufactoring process itself (too little plasticiser), in which case there's likely no difference whatsoever on such a short piece of pipe, and storage time and conditions before the purchase. As far as the latter goes, temperatures would affect the pipe evenly, but sun exposure might actually only affect one exposed end, assuming that particular pipe wasn't on the outside of a batch. Heating does weaken the material to an extent, but as long as minimal neccesary heat is used, it should be fine. The biggest issue is that heating accelerates the escape of the remaining plasticiser, unless you absolutely torch it, of course, in which case the polymer might start breaking down too much (some of it will still break down since heat guns heat things up rather unevenly, hence the need to work in a well-ventilated place - PVC is a nasty thing when it comes to the products of it's decomposition)
