Figure 7, seen below, is a side view of one test specimen, whose material may vary depending on the test. This is how they will be aligned in the jig. The rectangular jigs will be placed in the gap spaces.
*jig can be spring with boards on either side (will remove tolerance error)

Parchment Paper | Wax Paper | Saran Wrap | PFTE Tape | |
|---|---|---|---|---|
Ease-of-use Weighting: X2 | Use sheets to cover exposed areas. Some openings will need to be taped up 7/10 | *Same as parchment paper 7/10 | Cling wrap does not need tape. Works fine 9/10 | Needs to be taped on to all exposed surfaces 6/10 |
Effectiveness Weighting: X3 | Epoxy peels off easily. 9/10 | Slightly worse than parchment paper. 8/10 | Same as parchment paper 9/10 | Epoxy needs to be chipped off of tape. Stickage may occur. 5/10 |
Affordability | 12 in X 75 ft $7.99 CAD @ Canadian Tire | 75 in $4.49 CAD @ Canadian Tire | 25 m $1.79 CAD @ Canadian Tire | ½ “ X 480” $0.79 CAD @ Canadian Tire |
Maintenance | Remove tape and paper after each use | Remove tape and paper after use | Remove wrap after each use | Can reuse multiple times |
Feasibility | Can be found in most retail/grocery stores | Can be found in most retail/grocery stores | Can be found in most retail/grocery stores | Can be found in hardware stores |
Level of Obstruction | *Reference | Thinner than Wax Paper. | Thicker than Parchment Paper. |
Results:
Parchment Paper = 41 pts, Wax Paper = 38 pts, Saran Wrap = 45 pts, PFTE Tape = 27 pts
