Rotating shelving- Constraints

This project is challenging because it has a couple of constraints

  1. balance- the baskets/shelves need to hang almost at the top so that they pivot in a way where they are inclined to stay face up. This originally caused difficulty in designing when I came to realize that the original Bramble and Hare design had custom made chain which I couldn’t manufacture in the time period we have for this project so I had to design differently.Image result for bramble and hare (https://www.anvildistillery.com/blog/2015/10/5/boulder-bar-tzar-extraordinaire-griffin-farro-of-bramble-hare-uses-anvils-fabulous-creamy-vodka)
  2. weight- the bearing in the center needs to be able to support both the static and dynamic loads on the unit. As I don’t know what I will be loading this with yet (liquid is heavy, plants are less heavy) I had to  choose bearings that could hold a lot of weight. I ended up choosing a bearing with a 300 lb static load capacity.Image result for bramble and hare (https://www.tripadvisor.co.uk/LocationPhotoDirectLink-g33324-d3331404-i123697383-Bramble_Hare-Boulder_Colorado.html)
  3. aesthetic- I have to balance the cost of this project with the aesthetics I am shooting for. Every time I add a new pipe fitting or look for a pipe or wood within my color scheme my cost tends to increase. Currently each of the three shelves has 16 pipe fittings and 20 pieces of pipe.
  4. support- I am unsure how to aesthetically support my structure in a way that will bear all of the weight and look appealing.
  1. symmetry- I need to be sure not to over screw any pipes into their fittings to ensure that all shelves fit together and look symmetric.

    I can tell that you thought through a lot of the constraints carefully. Something to consider, if one of your main concerns is the balance of each shelf: maybe you could add some counterweights to the bottom of each shelf. Some sand in the piping or something like that might be a surreptitious enough to still achieve the desired aesthetic. But, if you were to do that, you would have to be mindful of how much that adds to the overall weight of the item.

    Hi Jamie, I really like the idea for your main project! I do agree that these are relevant constraints that are essential to keep in mind during the build of this project. I think utilizing the pipe fixtures is a great idea and I am excited to see how you come up with a solution to aesthetically support your structure.
