Anyone ever seen specs for make a fin to mount on your roof for the show?

I've tried searching a round but no luck so far.

I sent a link to this thread to D PHarm Boy for you.
If/when he chimes in, you'd be wise to listen to what he tells you;

thanks.

I bought a bootleg VHS of the Jones Beach Fruitcakes tour-if you want to trade

Paint is drying on mine as I type...

Couldn't find specs either, so just made my own.
Here's what I did:
Cut fin out of 1/2 in. plywood (approx. 4'x4'). Sandwiched two 2x4 boards along bottom. Mounted to a 1x5 by screwing up from bottom. Will sit in a ski rack. Should be very secure and weather proof.

Once the paint is dry I'll mount it on the car for a test run. Let me know if you need/want photos/specs.

That's the technique I have been promoting since I made mine that way 8 (has it been 8?) years ago.

It works well especially if you have sliding racks on the roof to secure it. EIther that or some bungess or heavy duty twine.

Any problems with it shifting/leaning going down the highway?

I also modified some pvc pipe to make a flag pole and holder attached to the fin (To be raised in the parking lot, of course).

When it was made for my original vehicle, the base (which was wider than yours) fit perfectly side-to-side and I slid the cross racks to fit it front to back.

We have switched cars twice since then and I drilled small holes about 2" in at each corner of the base and use those to affix the twine or bungees to keep from moving.

Luckily I only live 15 minutes from the Tweeter in Camden and Only have to be on the highway for about 6-7 minutes of that time. But no problems.

I have laid a towel under the fin to keep it from scratching the roof. Again that depends on your style of roof rack.

Thanks for the advice.

I added another piece of 1x where it will sit in the ski rack to snug it up (thickness). The ski racks keep it off the roof so no scratches there. It is somewhat proportional to the Suburban it is going on, so my concern was for a cross breeze catching it and moving things sideways. May just take the back roads to the show to avoid any incidents as I have about a 40 minute highway ride to Great Woods (the "Tweeter in MA").
