I solved a problem and am pretty pleased with how I did it. I'm now curious how others would have solved the same problem.
Here's the problem:
You have motorcycle pipes that you're going to install a 'lollipop' baffle in. A lollipop in this case is a screw with a loop end that gives straight pipes some resistance in air flow to give it some required backpressure and improve sound (see image).
The challenge is that the lollipop has to be mounted 6" from the end of a set of pipes (1, 7/8" inner diam.) that have two bends in them, one of them a bend in the end 3" from the tip (meaning your lollipop has to go another 3" past the bend). I posted a photo of the pipes to help with this 'puzzle' (below).
After drilling the 3/8" hole in the right spot on the inside of the pipe, the challenge is to get the lollipop down the pipe to the drill hole, and then it has to be righted up so the bottom of the bolt comes through the drilled hole and THEN you have to mount the nut onto the 3/8" tiny bit of bolt that sticks out of your hole without the bolt being pushed back into the pipe. NEXT, you have to be able to turn/tighten the nut until it's tight enough to keep it in place for the life of the pipe, without the lollipop spinning around, and so that it orientates so the lollipop 'face' (not the edge) is toward the airflow after tightening hard enough to keep the bolt in place for the life of the pipes.
I'm very curious how you guys would do this. REMEMBER, the pipes are curved in two places and the lollipop has to be mounted between the bends. How do you orientate the lollypop so the bolt comes through the almost exact size hole in the side of the pipe. How to you keep it from falling out when you try to mount the nut onto the tiny stub that comes through the pipe? How do you keep the end inside the pipe from spinning when you tighten the nut? How do you ensure the orientation is correct (lollipop faces the right way inside the pipe) inside the pipe when you can't see it looking down the pipe, due to the bends in the pipe?
