Backyard Roller Coaster Steel Tubing Bender - Part 2

Okay. Last week's tubing adventure didn't go so great. John and I took another shot at it today. The spiral is crucial to getting our barrel roll feature to work. Can we finally get it right?

"Our radius is so tight....we would never live" 🤣😂

[@granthunsberger5300]

Even before they started it up, I thought to myself, "Watch, he's gonna turn it to his right and it's gonna go into the ground."

[@martysmith9167]

Hey Will,
The way I see it you are on the right track, you just need to put scale on your bender. You can measure the distance between your bending wheels, center to center, calculate the deflection you need to create the proper radius and mount the scale perpendicular to the pipe to measure the deflection. That with some trial and error with the rotation and you will get what you want. Good Luck!

[@kevins1242]

It can be saved! Run it through from the other direction (almost like it running backward when you first turned it on was trying to tell you something). You can still turn your wheel clockwise then. You just need to remark the ground for your angle references, or turn your bender around. In my mind, it'll bend into the sky instead of the ground

[@ronald9269]

Hum why can't you make a radius jig and bend the pipe on that while heating it ? Idk just a thought!

[@Mattipedersen]

I'm probably way late, as always and I'm sure this has already been suggested.. But, since you've already gone 1/2 way (180 degrees), why not just pull the rest of the pipe through, as is, and run the pipe bender in reverse, thereby feeding the straight portion of the pipe in, reversing the turn, to complete the last 180 degrees.

[@ZoniesCoasters]

Well, nowhere else to go but up.

[@TheDanEfranChannel]

It's irrelevant because your radius was so far off, but couldn't you just flip it over and continue? (Kind of like re-addressing a nut when you've run out of room for the wrench.) It might be hard to continue the curve smoothly enough, though.

[@curtiseisenbeis2484]

Hey, I just thought of an interesting idea. Maybe put in some cheap lights for those late night scary rides.

[@magnetmantalkstoyou]

I'd say get some ice cream out there while you are working... helps with the thought process. Saves on Mistakes.

[@charliew1822]

Honestly I think you're almost there. Twisting was a really good idea, I didn't think that would work but now knowing that it does that's definitely the way to go. My concern at this point is that you would probably want to have the turn be more extreme at the top of the inversion than at the bottom but that's an easy fix where you change your angle lines on Chalk to be further apart at the beginning and closer together at the end.
Have you decided on more constraint numbers having to do with the length of the inversion, the height of the inversion, and the width of the inversion? (that is to say the height of the heart line above the track.) I just got back from IAAPA and would love to help you more with those better numbers. You're almost there! keep working at it
keep thinking at it
keep buying more Steel
Good luck!

Save some money! You can still use the candy cane. Just chop the curved part off, set it aside, and bend the next section. Repeat. Weld the sections back together when done. When you make the cuts, put a mark so that you know how/what orientation the pieces go in relation to each other when welding. Good luck!

[@ausinka]

looking at this atempt i would say you would only need 90 degrees of turn over full length. But without CAD i’m only guessing.

[@aaronbeaty377]

please do the corkscrew idea that i had on the planing idea.

[@fadeawayjay887]

Can you use a motor on the cart to make it like a launch coaster

[@ghosttrainproductions1614]

Where is that the tubing for the loop that you're adding to the backyard roller coaster?

[@BikerFail16]

Derrick Fields I believe that was supposed to be it

[@asterisks3062]

Nice, when's your next video on this

[@DAZARI0]

Could you have re-inserted or twisted it 180 deg, so the spiral is pointing upwards and proceeded counter-clockwise?

[@fadeawayjay887]

Can you make it a stand up coaster

[@eyezat1]

Don't build in one peice?

[@-lenin-8786]

It missing something...

[@fadeawayjay887]

Don't make it a exact circle though
