I have only ever used poly pro hoops with rivets and am making a bunch of Poly pro hoops in the next week or so. My question is if the friction connection is reliable without tape. I hoop hard and put a lot of momentum into my hoops and dont want something that could pop apart while performing. What are all your experiences with friction connections? I like the idea but am skeptical...
Well technically all hoops are friction connected but you use rivets to secure the connector in place. You have a good reason to be skeptical friction connection is not a reliable connection for rough or fast hooping styles.You can use epoxy/ super glue on the connector and sand it to add friction but bonding gels or spray is not permanent. The friction connection can even loosen if the tubing is warmer than usual, ex. if you use it on a hot day during summer at a music festival in direct sunlight.
If you're making fire hoops... rivets.
Don't think anyone mentioned fire hoops, but yes, it's probably a good idea to use rivets if you are using a fire hoop due to the added weight and stresses on the hoop.
However, for most polypro users, weight is a factor to be considered (that's one of the reasons polypro is so popular). Friction fit certainly has some advantages. Rivets are more secure, but do add weight, and can also result in sharp edges on your hoop if they get banged or stretched. Friction fit can be secure as long as the fit is good. The length of the connector can be a factor as well (a connector that is too short may tend to slip). If your friction fit slips, you need a longer connector tube. Some hoopers have also lightly sanded the inner tube, which results in a snugger fit.
Friction fit is the best connection, as long as it's done right.
lol i'm sorry the rivets add weight idea is not right. I have had so many hoopers think rivets are heavy and will off balance the hoop, WRONG. Just weighed two 1/16 rivets and they only weigh 1.0 grams.... that is so light!! As for the rivets having sharp edges. Well if you getting it from a seller they should take the time to sand down any possible sharpness from the riveting process. And if your making them just use a high grade sand paper or a quick scratch on cement to remove that extra metal sticking out if it's there. Which if your riveting gun is working properly you should not have a problem with the sharpness. I politely disagree that friction connection is the best.
Fair enough, ultimately it's really a personal preference thing. You are right, the weight is certainly not that significant, and the peace of mind you get from a rivet may be worth while, I just likt the simplicity and clean finish of a good friction fit.
My polypros have never just held with friction. Even with tape they are pulling apart. I think I may try some crazy glue on them today to see if that will work. Fun Sunday project. =)
So if you rivet them together, don't you loose the ability to coil them down for travel?
I sense there is inconsistency in the tolerances (if that's the right term) of the tube manufacturing. I've received a variety of connector tubes (and rolls) that look pretty much the same, but some are a little bigger or smaller than others. Some have a real nice curve, and some seem a little too straight (not sure if it's due to how they are manufactured, or how long they sit unrolled). So getting the right connection can be a challenge. We build each hoop individually, and no two connectors are exactly the same (some longer, some shorter). Sometimes, the inner diameter of the main tube can be a little smaller or bigger (especially from one colour to another).
Sounds like the right term. And yes, the variances get smaller (generally) the more you are willing to pay. Also remember that hoop materials are temperature sensitive, and may change size depending on their individual temps.
I rivet one side and do a push botton on the other. The hoop stays together nice and tight because of the push button, the other side is secured with a rivet and I can still coil it down.
i have 2 polypro friction fit hoops, one's a plain hoop, the other is taped. I hoop pretty fast and do hard reversals, and mine have never come apart - and each hoop has TWO friction-fits so i can take them apart for mini-hooping. The part that fits together is extremely tight, i have to use all of my strength to take them apart and put them together, and they are also sanded so the friction is grippy. My only disclaimer is that i havnt used them in the hot sun, so potentially heat could loosen the fit. If you are worried i'd stick with the rivits :)
wouldn't you know it, i popped my friction after writing this.
