Excuse the poor quality pictures… I couldn't find any better pictures of them, so I used my phone to take pictures of old pictures off my FB page, but I think you can get the idea. I finish these off by getting some cork sheeting from the hobby store, then I spray the underside with spray adhesive, (don't spray the cork or the cork letters will be sticky!) then I attach the cork to the underside of the coaster. It helps soak up the condensation, and protects the table top. I've made these for events like the C4C (Crawl 4 the Cure) also in other vehicle logos. I make the gear out of quarter inch steel, and the logo from some thinner stuff like 14 or 16 gauge.
For other ideas, I have also enlarged the design and made a few larger signs, like this 12 inch jeep sign.
