Here’s where we are in our glass projects:
- Look at the post below about the stained-glass window project to see what you need to turn in and how. I’ve made some changes: I want all your individual windows (5+5) turned in to echo from now on — if you don’t like your current grade on that. So, talk to me or email me if you’ve turned in late work and want credit for it.
- Phase 2.1 — nets — are done in Sketchup with names like triangle 1 [firstname] [lastname] and rectangle 1 [firstname] [lastname]. Then add 2.2 — folded nets — to the same file just like I showed you.
- Phase 3 is to make a solid version in the same file using the Push/Pull tool. Now all 3 shapes on in the same file. Phase 3 shapes represent solid prisms, and you must get ready to price their production differently.
- Using Excel (or OpenOffice Calc), make a spreadsheet that shows the total perimeter, total surface area, and total seam length of each phase 2 shape. Then cost out the production of each prism, showing the unit cost of clear glass, copper tape, flux, and silver solder. If you multiply each prism’s dimensions times the unit cost, you’ll find your net costs. Then add in 30% gross margin for each prism. Finally, come up with a cost to the distributor of each prism.
- Phase 3 involves a different kind of costing. So far, I haven’t been able to find a source of materials for making the solid prisms. So here’s the challenge:If you’ve made all your model prisms in Sketchup (your “C work”), I’ll give you an B if you find the perfect material for low-cost solid prisms and give you an A if you tell me the correct manufacturing method to use. Finally, I’ll give an A+ to anyone who can also find a wholesale source for the material. Happy critical thinking, and happy hunting!
