Paper Dispenser

The Design for this vacuum hub came about from my paper roller design. Within the main workshop we often hosted activities that would cover the tables in hard-to-remove products and stains. With this issue, we ordered a large roll of paper to be cut and laid out across the tables to better protect them. But with this large roll, there was no way to properly move it around to cover the tables in an easy fashion. I was tasked with fabricating a mobile holder where I made the following design to be put on casters.

Vacuum Gate

by Bryan Bushey and Trevor Neal

Within the machine shop we have many wood working machines that need vacuuming to keep the air clean and breathable. The vacuum in the shop is a PowerMatic with dual filters and bags. With the loss of suction by hooking up the three other machines to the vacuum created a loss of suction to the ShopBot. This was causing a lack of a safe operation. A challenge with the ShopBot is making sure there is no build-up of sawdust around the drill bit. When there is flammable sawdust near a drill bit, it creates a massive amount of friction that can only lead to one problem. To solve this, I designed and built a four-way switch. The gates on every outlet. This allows me to turn off the vacuum to certain machines and give power to the one in use. The previous method for this was physically removing and replacing the 4-inch pipe.

One issue for designing was keeping an air-tight seal. By using finger joints, this opened holes in the final product for the CNC paths of the production. With the help of Trevor Neal, he created 3D printed plugs to fill the holes along with a silicon caulk gun to fill the seams between planes.

Pull Out Drawer

The Engineering department at Sacred Heart University created an electronics kit that included the necessary equipment to conduct their classes. The issue was there was a lack of storage in the space for them. Originally, I was tasked with creating a shelf to store them, but we soon realized that the boxes on the bottom would be too difficult to reach on a regular basis. My team and I settled on a pull-out drawer. I designed a drawer to hold all 16 kits as well as have room below to store two large containers with extra supplies.

After some measurements and evaluations, I was able to drill in place the rails which are rated to handle up to one hundred pounds when fully extended. This was necessary because of the weight of the drawer itself was constructed out of ¾ inch plywood.

My main problem with the drawer was a miscalculation of the placement as the rails have a push-to-open mechanism. When pushed incorrectly the drawer would not open making it difficult to open the drawer. After moving the rails and cutting back some of the panels, I made the drawer flush, thus making it a press to open.
