concrete submarine hull sand and gravel
...good point brian - in fact you need 3 groups of korn with certain
specification of roundness and hardness to get good concrete any construction
company can advise you in that - also test some cubes of the mix you use during
building.
But most importantly - before you start building any submarine - have a good
plan how you will run and maintain it, what you will use it for - how you will
finance it what will be the cost of maintainance - similar as in yacht building
you may opt to buy the hull - and build only interior by yourself - i had to
build 3 hulls to figure it out - learning by making mistakes is cost intensive
and dangerous...cut those costs.
I can state where and how i do a project when i have size, requirements and
budget - this is why i say before you start - have a plan - write numbers down -
share your numbers with other people to see if realistic ... do not make a boat
first to figure out later what to use it for...
