If you believe that, please describe how it differs from atmospheric pressure when the vacuum bag is not present.
Why would the foam deform?There are no additional forces being exerted on it,but the bag ensures that the laminate stack enclosed by the bag is...
I would think this question ought to be addressed to the OP as he is one of the team facing the challenge.For myself,I would sit the mould on as...
That is a totally feasible approach.I would point out that correctly applying a vacuum bag over foam isn't imposing any forces other than those it...
Having good 3D files with the normals facing the right way is an excellent state of affairs.Using foam that will survive the forces of the vacuum...
I see that Rumars as advanced the discussion.He is entirely correct about what can be achieved by machining directly but before anybody gets too...
A sketch of the hull form would be useful.Are there chines?Is the surface developable?A foam female mould wouldn't be my first choice,but in the...
I know it is sometimes criticised for being easy to fake paperwork but do bear in mind that BS1088 required veneers to be of durable species and...
Its about 70 years since Paul Elvstrom developed the self bailer and they work very well.Why would anybody choose to add the weight and...
They did it! From what I saw on the youtube livestream earlier,the boat looked a little worse for wear but was still moving at a good pace.I read...
You just might rethink that approach when you are in the middle of refinishing the outside surface.
Joined today and telling us about some new software?To use one of the more memorable lines from the film "Muriel's Wedding" ,what coincidence!
I think the answer to the question posed in post #978 is "scarcely".For any rig to go upwind it usually requires a tight luff to maintain an...
Not to mention no bow wave..... This,on the other hand was a real boat,designed by Dick Carter and has more than one mast.It has no sails set on...
I think I would categorise Sodebo as an aft rig example,rather than an aft mast boat.The bows of the hulls are so fine that there would be...
