fingers(?)

For the finger-hook molding and casting project, we began by measuring out 6.75oz water and 1.5oz alginate for the mold using a scale and silicone beakers.

Once it was fully mixed, I held two of my fingers in the alginate until it set, and then measured out 10g water and 35g rockite for casting. I accidentally poured the rockite mix to where I couldn’t exactly see where the finger holes were, so I struggled a bit when I tried to put screws in with the jig. Thankfully, I figured it out and was able to secure the jig in the right spot using tape so everything would dry in the right position. After I set that aside, I washed the beakers I used.

I came back the next day to remove my solid rockite fingers from the alginate mold and wash out my beaker. Since I couldn’t tell how the screws were positioned when I put them in, one of them was too close to the edge and slightly pokes out of the side of the finger. Thankfully, it isn’t super noticeable, but it’s still unfortunate.

Next, I sanded the top edges of my fingers since they had some excess material from the overflow. I used 120 grit for the initial material removal, then 320 grit for a smoother finish.

After that, the fingers were ready for spray paint and clear coat.

The green spray paint I chose looked nastier than I anticipated, so maybe I’d do a different color if I were to do this project again. Finger wall hooks are already a freaky project though so it’s kind of fitting. The last image above shows my finished finger wall hooks on top of my clean work space.

Cost:

  • 6.75oz alginate = $3.37
  • 35g Rockite = $1.77
  • 3 Silicone beakers = $10
  • Spray paint = $8.89/15oz at 20sqft/oz = $0.03 for 1sqft
  • 2 screws = $0.14
  • Labor = $7.25/hr x 2.5hr = $18.13

Total cost = $33.44
