- Develop the centreline/profile
- Develop the base shape
- Fill in the stations along the length of the profile
- In this case, I added a “tunnel” to reflect how the final tank shape might sit on the bike.
I used pieces of pipe I had lying around to ensure all the bends that were supposed to be the same, were the same.
I folded the base template along the centreline and drew a “half” profile straight on my steel bench with a marker, then simply bent the welding wire to match the marker line. Repeat to make an identical second half. Weld.
Here’s some pics to show the finished product.
