Help build a musical PVC bench, improve a St. Paul community and learn how to solvent weld
Hey, thanks very much for checking out my blog!
Last week I promised to discuss the influence of Chuck Taylor shoes on my chair design. However, I need to take a short break from my rocker to create a bench for a block-improvement effort in the Dayton’s Bluff Community.
This is the bench that I designed for the block improvement effort at Dayton’s Bluff. To construct it, I must solvent weld 210 pieces of PVC pipe. I need a few volunteers to help cut PVC pipe and solvent weld so that I can finish the bench by July 20, 2013.
In this post, I will describe the bench design and invite you to help build it! Interested? Shoot me an email at [email protected]!
All participants will learn how to solvent weld PVC. The skill is used to build many exciting maker projects from potato launchers to musical instruments like the ones played by the Blue Man Group. In fact, the bench that we build can be used both for rest and to play a few tunes while waiting for the bus!
Two sets of foam-rubber paddles with wood handles will be attached to the bench using a small gauge steel cable. The paddles create a musical sound when the player strikes the top end of the pipe (the foam rubber must cover the entire opening) forcing the air out the bottom very quickly. The length of the pipe determines the pitch of the note. Shorter pipes produce higher notes and longer pipes produce lower notes.
To make construction easier, I designed the bench in 6 sections. Each section is 39 inches long and 19 inches wide. Five of the sections are identical (just oriented differently) and one section is unique. Once I have all of the sections on site, I will bolt 3 pipes from each section to 3 pipes in an adjacent section.
Pink, orange and green colors identify 3 of the 6 sections that comprise the PVC bench. The bench will be made in sections for ease of transport and installation. The Dayton’s Bluff Community Council will remove the bench in the winter to avoid damage from snow plows.
The design uses PVC pipes of 5 different lengths with the longest pipes serving as the legs of the bench. Standard bench height is 18 inches and each section of the bench has four 18 inch-long pipes. Placement of these bench legs will be important for balance and stability.
This is a view from underneath the bench illustrating how many 18 inch-long PVC pipes there are in each section. Only the longest (18 inch) PVC pipes touch the ground and, thus, it is only the 18 inch pipes that are displayed in this view.
