Hey everyone its Forest from the OAVS Team. Jon and I managed to do a completed design and manufacturing print package in 12 days in order to get the project back on task. We will be sharing some PDF versions of our 3D Solidworks model and some examples of the print in our print package on the sight soon.
Right now everyone is on winter break here at the University of Maine. We aren't going to take a break from the project though. Before everyone left we sat down as a team and made an aggressive plan to finish the Flow-Bench entirely before classes start again on Jan 14th. Jon and I live locally to the school and work on campus at the AMC so were are around all break. Matt and Dan live at opposite ends of the state north and south of campus. We devised a plan to accommodate everyone. Since the Bench will be built at the Advanced Manufacturing Center, Thanks John, and we need a load of materials and parts we split the tasks. Matt and Dan have split the raw materials and the purchase parts up and will be doing what ever it takes to get them to Jon and I at the AMC on time and on schedule. When the materials and components reach the AMC Jon and I will uses them up as fast as we can. The plan is to have all the Machining and Metal Fab done when Matt and Dan get back so we can assemble it as a team.
Current progress, Matt put in the purchase order for our first shipment of materials 2 24' lengths of 2 x 2 x.125THK 6061-T6 aluminum square tubing. It arrived on Thursday this week from Bangor Steel, free delivery. Jon and I commonsensed to measure 3 times and cut once as we have a limited budget and hope to sell the leftover length to recoup some money. We had it all cut, cleaned and deburred Thursday night after work. From there Jon hopped on the lathe and started knocking out the caster bosses that need to be welded into the lower frame work. He finished all four by the end of the night. I jumped on getting the base frame work TIGed together. I haven't made a frame like this in awhile so I took my time walking it straight using the welds. Jon and I took it back and forth to the surface plate half a dozen times to lay it on four 1-2-3 block to check it for flatness. All said and done I managed to get it within .010in of flatness in the 4ft span.
Jon and I worked a half day Friday and and started on the bench at noon. Jon turned the threaded flange for the flow straightener out of 6061-T6 and used the rotary table to do the hole pattern. I set the top frame up and tacked it together and tacked to the legs on so they could be manipulated after being joined with the straight fully welded lower frame. What and ordeal, after messing around with the frame for 4 hours I realized the 2 2ft framing square in the shop are bent from being used as guides for the plasma arc. Jon and I measured the diagonals on the frame a dozen times and they all came out within a 1/32in yet the squares would say all 4 corners in a square section were tight. We quit for the night after that and will get back to it next Wednesday.
Have a Merry Christmas, OAVS
