Mini Tank Construction

What I said I would do:

 Create a ~2’ x 2’ useable model

o Membrane

o Plywood

o Glue (wood)

o Angle iron

o Clean-up any failures

 Week 1: all materials on hand

 Week 2: tank built

 Week 3: demo

What I got done:

 Week 1:

o Acquire steel (cut to size by SMC)

o Buy plywood and cut to size

 Week 2:

o Bottom frame welded

o Holes drilled with countersinks for fasteners in frame and uprights

o Acquire additional steel for top frame

o Begin prepping steel for top frame

 Week 3: o Holes drilled with countersinks for fasteners in top frame

o Finished welding top frame

o Welded uprights to bottom frame

o Welded top rail to rest of structure

o Fitted plywood panels into structure

o Cut windows in side and bottom panels

o Used a router to create “ledge” for Lexan

o Fit liner into mini tank

o Water test

o Fit Lexan windows with liner in tank

o Silicone windows

 Created a ~2’ x 2’ useable model

o 2” x 2” x ¼”/3/8” steel angle box

o Holes in angle to secure plywood and liner to steel frame

o 5 plywood panels to make up the wall structure, with “window” cut outs

o 6mm plastic liner as membrane

o (2) - ¼” Lexan windows

o Siliconed windows

What I learned:

 Using machine shop equipment again

 Grinding

 Welding – what a correct weld looks line and what to do if it looks wrong

 Don’t wear anything I don’t want to get dirty when working in the machine shop

 Cut out steel where needed to create a flush surface

 Grind corners that are to be welded at a 45° angle for weld

 For top angles, ends should be cut to a 45° angle for a better weld (consult with other team members prior to cutting 45° angles)  A small block of steel will be drilled and tapped, welded onto the bottom of the tank, for the mounts

 Wood panels will be not be modular, they will be 6’/8’ pieces

o The windows will be in separate panels

 Use fasteners to attach wood to steel, instead of using “clips” at the top of the tank

 Move full size tank using an equipment dolly, provided by machine shop

Plan for weeks 4-6:

 Confirm the amount and lengths of steel needed

 Place metal order with SMC – need it in by 1/2/12

 Figure out how many sheets of plywood are needed

 Take apart mini tank

 Use steel and wood from mini tank for final design

 Start constructing final tank 1/2/12-1/6/12

 Tank needs to be complete at the end of week 5

o Motor, rails, cart, etc. need to be attached to tank during week 6
