Maybe not.  Sure you see ignition boxes bolted to the firewall on countless cars at countless events, but there are a couple of problems with that:  First is the fact some ignition boxes might be water resistant, but they\u2019re not water proof.  The firewall is a hot place in any car.  An electronic ignition system can make enough heat on its own. They \u201cprefer\u201d a cool mount location.  There are definitely better options:&lt;\/p&gt;\n&lt;p&gt;So what\u2019s the solution?  Simple.  Mount the ignition system elsewhere inside the car. On applications with dash glove boxes, it\u2019s easy to fill the glove box with ignition parts \u2013 particularly if you remove the glove box liner and build a \u201cshelf\u201d to mount the bits and pieces (the photos lay out that exact process).  It\u2019s also possible to mount the ignition box under or even behind a passenger seat  (this is particularly appealing in a dedicated drag car because it provides all sorts of access). Most ignition manufacturers offer extension harnesses, and honestly, the electricity doesn\u2019t care how far it has to run in the car.&lt;\/p&gt;\n&lt;p&gt;So far so good, but ignition and electrical components mandate mounting tactics that differ a wee bit from other hardware.  Wayward electrical shorts aren\u2019t the most pleasant things to deal with, and it\u2019s something racers have known that forever.  Because of this quite a few pro racers mount ignition and critical electrical components on non-conducting material. That means a metal mount is out of the question. Something like a sheet of thin plywood will work, but to make something that look good and lasts, consider plastic.  &lt;\/p&gt;\n&lt;p&gt;Obviously, when it comes to plastics, you have a lot of choices available.  One of my favorites for use as an ignition board is Delrin.  Delrin is called a \u201chomopolymer acetal\u201d.  It\u2019s very easy to machine. It is a very strong, rigid material that offers high mechanical properties. That\u2019s why it\u2019s regularly used to manufacture suspension bushings.  It\u2019s easy to come by and is available in a wide range of thicknesses, but keep in mind there are likely dozens of other rigid plastic sheet types out there that will do the job.  For an ignition board, you\u2019ll need something strong enough to support something like the weight of a coil and an ignition system.  Keep in mind that some of today\u2019s coils are considerably larger than their predecessors.  In simple terms, they\u2019re big and heavy.  So are full feature ignition systems.  Because of this, it\u2019s a good idea to cut ignition boards from \u00bc-inch thick board. &lt;\/p&gt;\n&lt;p&gt;In my formative years, I was a big fan of going directly from dream to concept when it came to building something.  I learned over time that was a pretty big mistake!  It\u2019s must more effective to make a pattern from paper first.   The truth is, it\u2019s a whole bunch easier to erase a pencil line on a piece of paper than it is to fix something carved out of metal or even plastic. Using a pattern simply allows you to check fit before actually building a specific component.  And it also gives you something to carefully follow (like a blueprint) when you\u2019re cutting, filing and drilling.&lt;\/p&gt;\n&lt;p&gt;I use heavy stock paper (smooth Bristol paper) for patterns. Artists use it, and magazine types like me often use it as a neutral background for shooting photos. In my world, once too dirty for photo purposes, it\u2019s recycled as pattern making paper.  You\u2019ll find this stuff is cheap and every office supply store in the continent stocks it. You\u2019ll need a good old-fashioned lead pencil; a carpenter\u2019s square and an 18-inch drafting ruler come in handy too. Ditto with a good caliper.&lt;\/p&gt;\n&lt;p&gt;When the time comes to draw the pattern, you\u2019ll either need the part(s) you\u2019re mounting or a scale (or better yet, a full size) drawing of the component mounting surface. First, lay the part out on the pattern and then figure how big the outside of the piece needs to be. When calculating the overall size of the piece you\u2019re building, you have to take into account the sizes of the fasteners you\u2019re using as well as the total number of fasteners required for mounting.  Why is that important? See the sidebar on edge margins.  You\u2019ll need to calculate them.  When figuring edge margins, I usually give myself some extra room. The fudge-factor allows for things like rounded corners.  And when discussing corners, you\u2019ll note (in the accompany photos), I never included them in the patterns I made.  Some applications need them rounded for clearance. Some don\u2019t. Some people like the appearance of liberally rounded corners. Others don\u2019t. You\u2019ll also see I simply marked locations for a hole with an \u201cX\u201d. The reason is pretty simple:  To transfer the hole location from paper to aluminum, I use a center punch. The \u201cX\u201d makes it a bunch easier to accomplish. Once I\u2019m satisfied with the pattern, I cut it out with scissors.&lt;\/p&gt;\n&lt;p&gt;As mentioned earlier, I regularly test fit the pattern.  Sometimes I fit the thing more than once too.  The reason is it\u2019s just way easier to test fit (and of course, fix) something made from paper than it is to build fresh parts. Honestly, I\u2019ve managed to engineer some pretty cool parts on paper, only to find they were completely useless in the real world. That\u2019s why test fitting is so important.&lt;\/p&gt;\n&lt;p&gt;Once you\u2019re satisfied with the fit, you can transfer the pattern to the Delrin. Although there are a number of ways to do this, for my purposes (and likely yours too), simply attach the pattern directly to the plastic sheet.
