Pre-Assembly Processes

There are some pre-processes that need to go through before assembling commenced. Once completed, the assembling processes should go without any tolerance and clearance issues.

Here are the processes:

1. Cleaning and clearing tolerance processes.

2. Making sure/checking the parts just fit in. Use the following tools:

  • Fiber carbon and/or 3D printed pins.
  • Built in pins.
  • Rod as hinge part mechanism.
  • Push rod.
  • Fiber carbon wing spar.

Tools Used for Cleaning and Clearing Tolerance

The figures above are tools that you may need to run pre-assembly processes but not limited to.

Cleaning and Clearing Tolerance

The figures above explains themselves how to use the tools except the heated rod. The heated rod is used whenever can not use drill for not reachable position such as cleaning or clearing holes for pushrod. Just push the heated rod quickly until it gets out of the hole so that it clears unwanted plastics inside the hole. 

Checking Tolerance (Making Sure It Fits)

Once you have done cleaning and clearing tolerance processes, need to make sure that now it fits each other when assembling.

15mm and 30mm Pins Clearance

Checking Built In Pin Clearance

  • Checking the built in pin fits into its pair by following the provided animation video.
  • By pressing the two parts, check if there is no significant gap or it fits in its position correctly.

Checking Rod Clearance for Attaching CS (Control Surface) Parts

  • Using rod to check that there is no resistance when inserting the pin.
  • Try to push and pull the rod checking if there is significant resistances.
  • Reprocess cleaning and clearing shown on the right side if found significant resistances.

Checking Clearance for Push Rod

  • Just insert the push rod into its position.
  • Make sure that there is no resistances.
  • Reprocess cleaning and clearing shown on the left side if found significant resistances.

Checking Clearance for Wing Spar

  • Just insert the push rod into its place.
  • Make sure that there is no resistances.
  • Reprocess cleaning and clearing shown on the right side if found significant resistances.

Finding and Checking Pin Position

The objective of using pins is to make the assembly processes run smoothly (fit in correctly). The process of finding and checking pin position is to make sure that the pins are well installed/used.

Finding Through Sliced STL Object

  • The two figures on the right side show how to find the pin locations by utilizing the Slicer.
  • Take note and ,next ,try to find them in the printed parts.

Locating The Pins Directly
  • Try to find the pin location on the printed part before gluing.
  • Also try to insert the pin to make sure it fits nicely.
  • Reprocess cleaning and clearing shown on the left side if found significant resistances.
