Foam?
Kerry,
Over the years we've seen metal shapers use Home Depot foam insulation material and PL400 glue to create a shape they desire to make out of metal. From the canned expanding foam, to rigid sheets glued to cars and re-shaped, there have been a number of different techniques used. Truly, I don't know if a foam shape can be considered a "buck", but it is one fairly cheap way to explore a shape. Recently a buddy of mine bought a styrofoam block, then cut and sanded to create his desired pedal car shape. Thoughts?

Here's a link showing Ron Covell making a buck for a fender, it gets you started.

Here is a combination buck for the front fender of my roadster.
I wasn't really happy with the design at that point. It did not have the swoopy shape I wanted. This evolved into a foam buck covered with bondo for making a true surface. My approach to that is in this post: http://allmetalshaping.com/showpost....10&postcount=8 I believe over the course of the roadster build so far, I've used about every buck style in existence from hard eggcrate, wireform, Bert, FSP. Never used any clay though. http://allmetalshaping.com/showthrea...highlight=deco

Lockheed Martin sent these foam check-tools along with my contract - in 2013, so it's current tech. Lockheed check tooling.jpg 24finalendview2 copy.jpg fits tight copy.jpg I can make 6 sets of skins from each tool, which is what the job calls for - a short run of modified birds. The foam is tough enough to be machined, secured, and then handled - with respect. The first run of skins only shined up the foam surfaces. hammer skin copy.jpg It is very possible to buy the two-cylinder foam kit, which delivers more than a cubic yard of expanding foam. Let it harden, sculpt it, and then give it an eggshell of f-glas gelcoat. Sand that and get the metal moving.

Kerry, this thread should be a sticky because it contains much of the criteria for deciding on how to construct a buck that works for anyone considering such a project.
