Method for making 3D shapes (used to make a bike fairing)

Step 4 Tape and Glue three Crescents together

The subject says it all. I use regular packing tape, you can probably use a lot of stuff, you just need it to contain the pipe glue and stoutly hold the segments together. Be very careful with the glue and sure to use lots of newspapers to protect your floor from the drips, they will eat through most floor coatings.
The procedure I used was to pour the glue out if it's can and into a large glass juice container. Then you can use a turkey baster to transfer the pipe glue into the joints, making sure that you have a nice smooth fillet (tapering at the edges) rather than a ball shaped bead (which would be weak where the ball intersected the plastic sheet). I included some pics to give you the idea.
You will find that it's easiest if the joint is substantially horizontal/below the area you're gluing (as per the pictures). This can be accomplished by working the joints up in sections: I glued three crescent segments together at a time (so that there are two joints that are substantially horizontal most of the time).
If you start with the non-elongated top/bottom of the fairing, it's a little easier.
