- Use Onshape to create a temporary copy of the system that has all components hidden except for:
- 8020 frame components. This includes all strut, brackets, t-nuts, and slide-lock parts.
- Fitting hangers
- Screws associated with t-nuts
- Create a cut-list for the 8020 strut. Cut longest pieces first.
- The length of the pieces must be accurate to the model and all cuts must be square.
- Use the rotary saw for long pieces and the table saw for shorter ones.
- Label every piece with its length
- Identify pieces which need to be tapped on the ends. Hold pieces in the vice an use a 1/4-20 tap held in the drill.
Assembling the Frame
- Start with the base of the frame and work upwards. Keep screws only loosely tightened until every piece has been assembled.
- For every piece of strut, check the model to find the number and type of t-nuts it has, as well as their order on the strut. This cannot be easily changed later. Insert t-nuts with the chamfered side up.
- Assembly sequence
- Base
- Legs
- Top
- VM and Process strut
- IM section strut
- LN Manifold and FTC bank bar strut
- Control box support bars
- Use the model to position the struts at the correct distance from one another.
- Tighten screws and square up the frame
- Use square blocks, clamps, and parallels.
- Tighten the screws which are threaded into the top bars at each corner.
- Position the inner width of the base and tighten the screws. Check that the base is square using a ruler form on diagonally opposite corner to another.
- Square up and tighten the front legs (IM) first, then position the back. The distance from the front to the base must be accurate.
- Tighten and square the top bars.
- Position the cross bars for the VM and Process section, but leave the screws loose. These bars will be positioned according to the plumbing.
- Position the FTC bank bar and use a level to make it flat.
- Assemble the bars for the IP carriage and LN manifold(s), loosely attach them to the frame.
- Loosely attach fitting hangers and control box bars.
- Double check for squareness and that all t-nuts are present.
- If a t-nut is missing, now is the only time to fix it before the frame is laden with plumbing and assemblies.
- Use rubbing alcohol to remove any sharpie marks.
