Step 3Chop bike 2
From the second bike we mainly need the steering assembly and top tube. There are 4-5 cuts to make depending on the bike. Cut the frame and fork as shown. Cut one side of the fork flush, the other side leave an inch of tube and cut at the angle shown.
On most bikes the stem (the thing connecting the steering tube with the handlebar) is aluminum, so you can't easily weld it. The stem can't be completely removed because it usually is needed to hold the steering assembly together. So we need to find an exposed area of steel that we can weld to. If the end of the steering tube is accessible that is a good spot, in that case just cut off the handlebar and excess stem. If you can't weld to the steering tube then you can weld to a steel handlebar. Cut the handlebar very short (maybe 3" long) to provide just enough space to weld to.
