Paranormal investigators have photographed what seems to be a "Banshee" haunting a building in the West Country...
-
Are you sure.
The image is titled Antidote 050. If this is true it is an ELWAY 5.
-
LOL
-
I have no idea why Graham titled the image 'Antidote 050'. Maybe he was / is planning to name the boat as a repost to ' The Antidote to panel games'. But it is the image he sent me and he is building a Banshee. I have spent much time discussing the fact with him.
Ross do you find something funny?
-
Does anyone have any more pictures/details of the space frame.
Am wondering what holds the rig tension fore/aft at the shroud/hull intersection. Is there a hull connection/some other funky triangulation/ or just moment capacity at the stump connection that is yet to be added?

Nothing does, as the shrouds go on the end of the wings, not at the hull...

On Atum and Antidote we conceptualised the forestay loading as being taken by the forward part of the hull being used as a cantilever, attached to the spaceframe at the mast step and where the shroud tubes cross the gunwhales and topsides.
Practically what this means is that the spaceframe is very firmly carbonned to the gunwhale/topside/deck over the main bulkhead.
-
I better not forget to add carbon at this point then.
Surely the forward component of this force is also shared by the aft beam connection because the rack tubes connect the fore and aft beams.

Hence why I asked :)
I'm not a massive fan on relying on moment connections between tubes, but the majority of the force is axial (as they are swept on plan) . I'm sure Cookie is streets ahead of us in the build of these and found it interesting that he has got rid of the gunwhales-frame connection.

Possibly, but we did not consider it in the design process.
-
Just to clear something up - there is (not in the photo) something between the sheerline and the top spaceframe tube. I don't consider it a requirement in dealing with rig tension, but more of a safety for the top tube to keep it in column.
The forward loads are all essentially triangulated into the stump (which is also shared by the jib track) through tension in the bottom beams and compression in the top tube.
Will post some more pictures if Graham will let me! Should be finished in a couple of days... :o
-
No one is going to bend our forward beams but i will connect them to the hull at the gunnel.
-
Sorry, I missed this post... the photo is entitled Antitdote just because the previous use of the camera was for pictures of Antidote, and it continues to name in sequence if you dont tell it not to.... which of course I didnt.
Mike, post as many pictures as you like !
-
Some newer, correctly named pictures in the boats section under 3204... with new shiny paint...
-
Looking very nice Graham. Got any more? Must be all but finished now?
