I've made a couple 4 piece collapsible hoops using rivets, tube insert and push buttons ordered from hoopsupplies.com. So far, I LOVE and highly recommend them! I make hoops to sell so I have to make it practically perfect.
1. My big problem is that by pieces don't fit universally. The pieces only fit one way, you can't mix and match. I've tried building a rugged jig with wood and drilled holes but it's so hard to get the tube lined up just right so the holes are all drilled uniformly.
2. Does anyone know how/where I can buy push buttons locally. Ordering them works but I need instant gratification and would rather drive across town to them then wait for the postal system.
This is the kind of travel hoops I want to make!! And hoopsupplies.com was where I was going to order the parts from so thanks for posting this! I love their stuff as well. I haven't attempted to make one yet because the only place to get certain parts is at Ace Hardware and it closes early. I am going to make it there soon and I'll let you know if they have push buttons (if you haven't already). ^_^
What size tubing do you use for these? I was thinking 1/2" 125PSI but from what I've read 100PSI seems to be better....what do you think?
I still haven't been able to fix my #1 issue but I've just moved to a place where I'll have access to a real shop so I hope to fix it soon. Issue #2... I've tried ace and they don't have them in stock. They said they could probably order them but the ordering guy wasn't there the day I asked.... I just don't know but I'll update soon.
I've ordered 2 different sizes of push buttons from Hoop Supplies for 3/4" and 1" tube so I can make both. I use 1/2" tube for my hoops but they don't sell as quickly so I haven't invested in push buttons for them yet. I don't think psi matters at all concerning the push button instillation, they're shaped to be somewhat flexible. I could be wrong though; I really haven't tried other psi's.
Miranda, to address your #1 problem, you on the right track with building a jig. You just need to make sure your jig is accurate and you line up the cut in your hoop at the same place every time, that way when you drill down you will hit the same spot on the tubing every time.
#2, buying them locally is usually not possible. I've never found any that work in hardware stores, I've always bought mine by the thousands online.
PSI does not matter so much with the buttons, the only thing you really need to consider is the tubing I.D. and the wall thickness.
