The SL-C’s nose is designed to lift off as a single piece. This works great for a race car because there are always crew members around to help you lift it off and you’re not worried about chipping the paint. However, if your crew is composed of your wife and kids, they’re not always available nor happy to be dragged to the garage when watching a movie or sleeping – yeah, last time I woke someone up to help move the nose it didn’t go well. Even with willing familial assistance you have to disconnect the wiring harness, make room to store the nose and you need to be careful not to scratch the paint.
What’s needed is a nose hinge. The primary challenge with designing the hinge is that the splitter projects in front of the body work. Since the nose pivots forward its leading edge will bind on the splitter unless the pivot point is low and in front of the bottom edge of the nose. While noodling on the on the problem I discovered that Bob, another SL-C builder, had built a working prototype. The following video demonstrates how easy the nose is to open when gas struts are installed.
Bob shipped the prototypes to me and I tweaked and redrew them in SolidWorks. I then sent them to Allan and he installed them on a SL-C that he’s building (see pictures below). Based on Allan’s feedback, I relocated a few of the mounting holes.
The following video shows the updated CAD model. The plan is to do a group buy and we're targeting a minimum of twelve hinge sets. There are 14 billet pieces in each hinge set and the two largest pieces have left/right mirrors, so they take twice as long to achieve volume pricing. We're working on pricing, but we're expecting to be in the range of a nice hot rod compound billet hood hinge.
The hinges are very useful to have early in the build. As soon and you have your body fitted you can quickly install these and you no longer need help moving the nose or finding a place to store it. Here are the top-level features:
- Very stable
- Easy to open
- Easy to remove the nose (two bolts that are outside of the body work)
- Billet 6061 aluminum
- Arms are 3/8” thick
- Includes all hardware (depending on shipping costs, we may or may not include the gas springs)
- Stainless Steel mounting hardware from McMaster
- Steel ball bearings from McMaster
- Steel drilling jig
- Easy to install (including finished cars)
