Because numerous people have been asking questions about the puncher from our early season reveal, we made a step-by-step guide for new teams to help construct a basic linear puncher.
@Droideka Follow up: How do you apply grease? (I never used grease so pardon me if i'm asking a stupid question)
As the resident team of applying grease in 574, our team has come up with very good strategies. First of all, use an allen wrench that is designated for this job. Find a really stripped out one, and never use it for anything else. Ever. Put the end of the allen in a tube, bucket, or other container full of lithium grease, and apply it liberally with the allen itself. Really your puncher should not need greased that much.
@Droideka to follow up what jack said, you can also apply lithium grease with a Q-tip, or just use your fingers, just make sure there is a layer of grease on the contact area between the metal slide rail and the plastic slide trucks. It shouldn't take much to see an improvement, but its often easiest to apply a lot of grease then wipe away the excess with a paper towel.
@Naman The puncher shoots quite far assuming the slide trucks are aligned properly, the slide rail is greased, and the angle of the puncher is at the right angle. Your mileage may vary depending on build quality, but our puncher can shoot the high flag from both starting tiles very consistently.
