Video of Z-Pressing and Cutting Out Panels

Category: Panels| Z Press| Videos — Babbled by Judy on July 22, 2006

Some time ago a mutual friend of Bob Oram and ourselves, Greg, created this video from footage he captured during the first few days of the Scrumble project. I figured it was time we took advantage of You Tube and presented the video here:

Video of Reinforcing Cutouts - Step 3 Taping

Category: Bulkheads| Taping, Layups| Building the Shell| Videos — Logged by Tom on April 16, 2007

The last part of the cutout reinforcing process is to tape over the shaped edge and uni insert.
We hope our video speaks better than my explanation. A few items to note:

  • The first few frames show the routing and layout of the uni in the trench during stage two.
  • The few edge imperfections were easily filled without fuss by roughly adding the filler to the correct spots and letting the taping do the rest.
  • I hung the beam up so I could access both sides at the same time.
  • The tape lays out and shapes much easier if the two outer supporting threads on each side are removed after wet out.
  • The layout out works better quite wet (almost dripping).
  • To assist layout through corners, I have to concertina the centre of the tape that is in contact with the edge of the cutout, (look carefully at lower corner layout).
  • The last shots are of small sections of peel ply which work best around corners.
