Brief Description: Continued Snorkel Install; Begin Air Ramp Mod
|
|
The first thing I needed to do was cut a square filter opening in the left front Inlet Floor. It was extremely tricky marking the cutout hole because the Snorkel, as sent to me, extended up over an inch into where the floor needed to be cut. So, when you put when bolt into the Snorkel/Engine Air-Injection interface and swung the filter up, the edges of the filter were all at an angle to the Ramp Inlet Floor. At first, I tried to make a paper template for the Inlet Ramp Floor, swing the Snorkel into place and mark the hole. In theory, this was a pretty good idea. In practice, it didn’t work. It was obvious I would have to first cut the Snorkel so it was lower than the Inlet Ramp, then mark the ramp and cut a hole. Now comes the dilemma, ”How can I mark the back side of the Snorkel to know where to cut?” You can’t even see behind the snorkel without using a mirror, so obviously, you can’t get a sharpie pen in there to mark it. I made an assumption (which was wrong!)…just mark the front of the Snorkel; measure down from the top of the VAN’s Prefabricated/Cut and cut the danged thing off the same distance all the way around the top. Surely the contractor VANs used to fabricate the Snorkel made these angled cuts accurately; just made them a little longer than needed to account for inconsistencies in the baffling! Now that I look back on all this after-the-fact, I should have realized that if I had to cut a mega-“Cheetos-Shaped-Hole” in the top of a Snorkel that was supposed fit perfectly for a IO-360 M1B Engine…hmmm? Oh well, C’est la vie as the French would say. Pic #1 is the cut for the Snorkel top. Pic #2 is the Snorkel/Engine Air-Injection Throttle Body interface.
