In my opinion, a good tech project should be innovative, help improve your skills, and be WORTH DOING! I was the proud owner of a nice little body hammer holder that I won at a tool swap on another board. It looked like this: The only problem with it was that the hammers piled up till you couldn't find anything. SO... I decided it needed a second level, one that would spin easily. I tried a couple of different lazy-susan bearing plates but none of them worked very well under load. a box of hammers and clamps and vicegrips is HEAVY. I decided to use a planetary gear set left over from a parts tranny I had and welded it to an axel I had laying about. If it could move a car this should be no big deal. Plus I wanted it to spin VERY easily. I welded one part of the planetary gear to an axel I had laying about: So far so good. If I stop here I have a great ash tray... Lets press on. Next I fabbed up a nice hat for it out of 1/8" plate: As you can see from the welds, I NEED the practice..LOL. Then I welded the other part of the planetary gear to the underside: Then I added some rods that were extras from a bucket of pegboard hooks I got a long time ago (Please do not laugh too loudly at the welds): They tell me the best way to see if your welds work is to stress them. Well, if these welds fail I get a hammer dropped on my toe as a reminder. Here it is with its hat on. I bolted the second deck on instead of welding it just in case the idea didn't work. I didn't want to screw up a pretty good tool: (sorry the picture is sideways...my camera is not good enough to get it in the other way.) I took it outside and added a nice shiny coat of Metallic Blue paint. I mean ya gotta have some bling, right? Then I brought it in and loaded it up: The most used hammers and dollies get places of honor on the front row: The rest sit in the bleachers: The top carousel spins with one finger. The planetary gear REALLY worked well. The final part of the project will be to attach a mid-level holder for dollies. My welding skills got a little better, the box of hammers is off the floor and I can FIND one now, AND BEST OF ALL THERE IS STILL SPACE FOR MORE TOOLS!!!!! The PERFECT project!
