Check out a low-tech approach to determining the right "lines" for your bike. 

This is the approach I used to decide on my tank and tail shapes.

Wire frames are an alternative to wooden/timber bucks. 

I'm not suggesting they're better or worse, just an alternative. 

Watch this video to hear why I'll be building a wireframe buck.

More lo-tech! 

Using some welding wire, let me show you how I formed up the center line of the tank and rear fender section!

This is one method of making a shaping buck (the alternative is a timber buck).

I'll show you how and why I built the buck like this.

The first step in building the tank is to make paper templates of the parts. 

In this video I'll show you how I formed the paper around the tank buck - and how this transfers to the sheet metal.

I made this tank in two parts: the sides and a top. Actually, three, as we'll need a base as well :)

Just using a piece of steel pipe, here is how I shaped the basic profile of the tank sides.

This lesson goes into detail demonstrating the process for shaping the top of the tank - probably the most complex shape in this build.

The first step at getting the tank together is welding the top to the sides. Watch as I demonstrate my process for this particular tank.

Here's an attempt - and a fail - and a second attempt at fabricating the tank base.

The tunnel was formed over some steel pipe, then the tank base pieces were welded to the tunnel.

Check out the how and why of the steps before welding the base into the tank!

I wanted to make the weld joint between the tank shell and the base invisible. 

Check out my process to get it done.
