Do a little reading about three or four posts up and you will see how they're made. Yes they require a hole beforehand. A press may not be required as you could probably do a lot of flared holes using a vise or a big bolt.

Question

So, how does one go about purchasing a set of these dies? Was it part of a group purchase that has already come and gone or ? What does the kit include?

Light Racing makes the die's that keith sells, You'll get a much better deal purchasing them from him than Light Racing. There also the same die's alot of use on the site have. Commander Chassis Is also going to start making them as well, so a heads up there.
Benifits/ Well you can put as many holes as you can fit into a project. I believe the main reason they are used is to lighten material while still keeping it strong and they just look cool too! As you get into bigger die's the more material will be flared. A .75" die will only move about 1/8 of material to make the flare while a 4.0" die will move about 7/8's material to make the flare.

There is really not an low budget way to make these....thats why they cost some much from everyone.....Light racing just gets such big quantities, and after heat treating they dont pay someone to stand there and polish them to a chrome like finish....so they cost less.

I suggest looking at the desert racing crowd on ideas and the guys here on the site. The different sizes are used a lot for the cosmetic look of the part which is why you will see a variaty of hole sizes used on one piece.

but the most important thing to remember is , yes they are used to lighten and strengthen a part you are making. But it can also have the reverse effect, a sheet can only have so much material taken out of it before the structure of it will not hold up anymore even with flared holes.

Get into a groove of what you feel looks good and what still retains strength....dont go all swiss cheese on it and expect it to be strong.....go through this whole thread and look at the examples, then you will start looking at or for these holes in other pictures, magazines, etc.

Sounds good guys, thanks. I'll be looking at picking up a set from you Keith in the future however I need to get a press first. Also, are there other die sizes we can get from you?

Any thin wall material, such as sheet metal, is subject to bucking/bending when loaded in compression. Flared holes can stiffen sheet metal so that it is less apt to buckle. Because it is more resistant to buckling, the part is stronger for situations where the material is loaded in compression. The part is also lighter since material has been removed.

The tradeoff is a stress concentration around the hole which can eventually lead to fatigue failure. In many cases where sheet metal is used to reinforce or stiffen something, fatigue does not become an issue. But even so, keep in mind that you could be weakening a part by putting too many holes in it or putting them in the wrong places.

I am saving my pennies for these dies myself and can't wait to have a set.

Just really curious about this flare. I have wondered if the 4" LED lights with the rubber grommet would fit inside that?

Have any of you guys been using bolts or a vise instead of a press to make your flares?

Funny you should ask that, I was thinking of trying that and also seeing what gauges look like in the holes.....

All my gauges are Autometer and they are a bit odd on the sizes. 2 1/16" and 3 3/8". It would look really cool resessed into a panel rather than just flush fit.

The inside of the 4" flare measures about 4.5"s, if that is to big a 3" or 3.5" flare could be used and rework the hole to make things fit!

I don't know about the rest of ya but im ready for the bigger dies!
Keith, any plans on possiably doing another by in on the 3 peice large set?
