These images show the 'soft wave ripple' carving over the banked curve section. 1st & 4th show the under side trims marked in preparation for cutting, whilst the last image shows the underside of the curve section near the base block mount. Here you can see the 'run in' cut to flow with the line of the base block.
The 1st image shows the 'under drop' cut into the flow of the banked curve. The whole section uses segmented tapers, rising & falling, then tapering down to the lower tail section. You can see the concept of the construction in the 2nd image. 3rd image shows the 'gap set' spacers. In the last images you can see the bulk carving being carried out with the use once more of the 'arbotech'. The final image is taken from low down at the end of the tail & gives an odd distorted view of the curvature. At this stage the mid point board is still un - carved & so stands out 'on edge'.
Tail section complete.
And now, creating the banked curve section. In the images below you can make out the board layout for the curvature. This section is 3.8 m in length. You can also just see at the far end the inclusion of the 'tail' section board arrangement.
Soon to be sourcing the 'York' stone slab settings.
We are currently looking to install mid June 2008.
The big sphere has finally been set within the sleeping dragon bench. This section has 1 subsection that caps over the sphere during installation. You can see in the images some of the subtle 'orbital' hollowing around the setting of the sphere.
The ring setting of the sphere was quite tricky to get right - numerous times the seating board sections were offered up to the sphere to get the correct radial concave hollowing recess.
next up is the seating section form the right hand end of the back rest section to the mighty knuckle block. Watch this space!
Most of the line weight shifts & bridges have been completed in the seating boards. The mid section base blocks are also almost complete. Still some trim adjustments to do on the rear of the blocks & also after re-assembling the seating board sections with the backrest have found another couple of lines that require some subtle alteration.
As you can see from the images the seating hollowing has been worked to a smooth blended form. You can also see the seatboard sections before they were re assembled.
Tools used include;
The arbotec - see previous entry. A good tool for removing stock rapidly, that's also it's disadvantage!
Convex spokeshave - a joyous handtool experience for cutting the hollow just the way it should be.
Rotary & orbital sanders.
Bench plane & belt sanders used for blending flat areas. Low angle spokeshave used to cut radius on rear edges of seat boards.
