In this project we are using torches, solder, pieces of wood/wood planks, metal wire, drills and flux. Right now we are piecing everything together and putting the rails on the wood planks to make a marble roller coaster. We've had some complications during the making process like for example some people in class would "accidentally" take other peoples tracks that they were brazing and then it would end up sending them back awhile in their building process. Luckily we are now towards the end of our building process so we won't really have to worry about anybody "accidentally" taking anyones things.
