Here's a little guide on CNC machining parts. Most people probably think that all it takes to machine a billet part is a drawing and the push of a button. Ha, I wish. Unless you have access to some expensive CAM software and a 5-axis machine, it's nowhere near that easy.

First you create a drawing. In my case, a 2D drawing of the front and back of the part is required. Then, using those drawings, you create a program that the CNC mill runs on. With the software we have, this means manually creating toolpaths, figuring out cutting depths, and generating code for each individual tool to be used. For this supercharger bracket, a total of 4 programs (front, back, fixture, facing) will have to be created to get to the finished part.

We're not done yet. After ordering material, the blanks have to be cut to the proper length. Then, each blank is squared up and faced (front and back) to the final thickness. The first op is the front side...

Before the back can be machined, the fixture has to be created. This fixture locates the blanks via 3 pinned locations and will allow the final part to be cut out of the larger material.

The fixture is clamped in the vises and the blank is bolted to it. After loading up a different set of tools, the backside program is run...

The part is then unbolted from the fixture, cleaned off, deburred, and voilà:

The only thing to check now is fitment on the bike. Think it fits?

Woohoo! All is good. The only thing left to do now is send out the bracket and idler pulley for anodize.

Is the stock header with the SET going to get trashed? I would have to think with a motor breathing as heavily as this you wouldn't want to stick with the stock headers.
