Elizabeth welding Steel Diamond Plate to Square Tubing Frame

Part Fabrication/PO Status

Testing Updates:

- Testing specificity (To Be Discussed with Guide)

4 students stood on the platform supported by only threaded nuts, their total weight = approximately 710 lbs. Students felt little deflection. No visible deflection.

Remaining Items/Problems:

- Handle and Wheels (Assigned to Elizabeth)

- Behind schedule for wheel and guard but not on Critical Path; team initially started a bit behind on this and owner has worked to get us back on track; eliminated side guards (the STFA will suffice) and decided to have front guard as dual purpose handle

Remaining Items/Problems:

- Welding will take time and we are behind schedule. This is on Critical Path. In process and highly complex. The changes we had to make to adjust for the Powder Coating caused a schedule delay. We are working to get back on schedule.

- Majority of pieces are cut; welding will be completed by Sean and Rob in place.

- Team has been discussing how to mark the pipes after powder coating so they go far enough into weldment for accurate assembly.
