Motorbike exhaust pipe question

You mean the springs? Well that´s easy, they are mounted to hold the exhaust system together. I´m using exhaust springs on my current project, a Ducati 916 (1/12 scale). In what scale are u building the bike/exhaust?
Since I´m a total geek, I´v measured everything on those springs and just give me the scale and I´ll give you the instructions. Here are mine temporary installed;

Hey!! thank you DukeMan!! I make in 1/12 scale how i make the springs??

PS: Amazing springs!!

Ok, first you´ll need a small drill bit, a 0,3 mm will be fine and some really thin metall wire (I used soft silver wire) with an 0,2 mm diameter.



Put the drill bit in your pin vise or in your x-acto shaft (put some paper between the drill and the shaft) with the "wrong" side pointing out. Roll out some wire, grab an end with a tweezer or something and hold it close to the drill.





It´s a bit tricky indeed



Very carefully start wrapping the wire around the drill, when you´ve reached desired length, take a side-cutter and cut off the spring from the wire.





Yeah it´s a bit tricky in the beginning, but as soon as you get the hang of it there´s no problem.
Making the loop (on the spring) is also a bit difficult, but again, use the drill and carefully bend until you get a good shape.
Making the loop brackets is the easiest part, just use the drill and bend a lot of U-shaped parts (I promise you that you will lose some), cut and bend them according to the original 1:1 bracket.



I used CA (superglue) to attach the brackets. From here all you have to do is deciding where to put them, but mounting them will not be the easiest thing to do, but a pair of tweezers and a lot of patience will help you through.

Hope this will help you, good luck!

Great how to Fredrik, you saved me some writeing because I don't have photos. I only tend to "squize" the spring when it is still on the drill, that way it becomes even and if you need to stratch it affter it will come out even. So you don't need to take care when you roll it on the drill (just not to cross the coils) and then just press it on the pin vise so that all coils touch each other.
Edit: I forgot, they are used to join the exhaust pipes, so you can find them on every exhaust joint on the bike.

another way to get springs is if you have a diecast lieng around pull them outta there or if you buy a modifier the usually come w/ extra springs( not sure if their the right sizr though)
