cuuting the hole in the wing for a snorkel

I went with the Southdown snorkel and I can make it work on the passenger side by weaving the hose from the snorkel under the heater and over to the air cleaner.
However, a body shop and then Shane mentioned that since I would be cutting through the seam where the outside and top wing pieces are joined it will weaken the wing and the aluminum could fatigue and crack.
Has anyone cut through this area (right in front of where the rollcage bolts through the wing) and then seriously offfroaded it? Did anything crack?

Have the same snorkel and cut the same hole. No problems.

Dido. I've had the same snorkel for 5 years and no issues.

"Im hurt. Ill have you know that a couple years ago I won third place at the PDX ABFM with that fine gem"

What category?

Seriously though, how did you cut the hole for your snorkel without the hole saw wobbling and making a mess? I cut a better hole in my index finger with the d%$# thing last night and had to go to the ER and I just started my pilot hole.

No pictures of the mess of my index finger. I don't even like to look at it.

Using a hole saw on an uneven surface, as you found out, is a very dangerous thing to do. It will want to grab, and do all kinds of nasty things. I try not to use them with a manual drill unless the hole is relatively small (like 1" dia or smaller). Depending upon the size of the hole, you might want to consider using a jig saw or air saw. Shane turned me on to the air saw for cutting my inner fenderwells, and it would probably work well for this if you have compressed air available. Another option is a keyhole saw but these don't work too well unless the metal is well supported.

Actually Ryan, I was putting the hole saw in the drill when I absent mindedly pulled the trigger as I held the hole saw with my left hand to tighten the chuck. My index finger was in the wrong spot and I wasn't paying attention to what I was doing. Quick lesson.
However, thanks for your comments on an air saw/nibbler. I do have compressed air and I wouldn't mind having a nibbler.

Wow, they're more dangerous than I thought

Glad you didn't get hurt too bad.

Well, I finally cut the hole

I went to a local body shop and he told me to use a hole saw with medium teeth, so as not to clog the teeth with aluminum. and drill it straight down. I also cut a hole in some hard wood, rubbed a bar of soap on the hole saw and inside the hole cut in the wood and clamped it to the wing. I then cut very slowly. It worked great and I finished off cutting the flanges where the outside and the top of the wing meet with a hack saw blade held by visegrips. I then filed everything nice and smooth and rounded.
For the raised portion of the intake the local muffler/exhaust guy took some 2 1/2" mild steel exhaust pipe and bent it to fit. I had the pipe and the Centri Precleaner powdercoated and put it all together. It works great. I held the Southdown rubber fiiting to the wing with rivnuts.
Here are the pictures.

Clark - Looks good. The block of wood was a great idea.

I've been debating the passenger vs driver's side snorkel. With the air cleaner where it is, the passenger side provides the shortest run. But some people say that it obscures your view. I've thought the optimum would be to relocate the air cleaner over to the driver's side, and run a DS snorkel. But I haven't scoped out how difficult that would be. There just seems to be an awful lot of hose to get to the air cleaner and then to a snorkel.

Ryan.

I don't find there to be an issue with it blocking the view. There is about 2" between the snorkle and the window frame and I don't even see the snorkle when looking that way. I liked the idea of a shorter hose and that is why I used the passenger side. The precleaner, however, does look like a small spacecraft is trying to land on my softtop.
