Title: O.R.S.V. foamy
Post by: portside II on February 05, 2010, 11:33:42 pm
Hi all i have decided to make another foam ship , my last one is a coaster which can be towed by even the smallest of tug's , but also has twin drives for general sailing .
This like the latest is built from a foam sandwiched between paper used as packing to protect palleted material's ,it's light and easily glued with  super glue and can be sealed for extra protection with bathroom sealant .
As the coaster is almost 5 foot long i thought a smaller vessil might be in order , so the new one is under 4 foot ( i think , not measured it properly yet  :embarrassed:) but is about the same beam and draught.
So as they say pictures speak a thousand words i will begin.

Oops  :embarrassed: a bit late now Martin as the hull is well on it's way now , and i dont know what macro is apart from a cash and carry store ,nope thats makro  :-) . Hopefully these will show more.
I have glued both sides together , drawing the bow to a point which is pinned and glued the bottom is then trimmed .
Bulkheads are then fitted to keep the sides straight and the stern made and transum fitted , all the joints after gluing are sealed with bathroom sealant and smoothed out . Thd drive and steering was the next to be fitted and this was simply a hole cut out, a dab of sealant and a couple of short screws to hold everything in place .The servo is heald in with blocks of ply glued to the foam only, i will have to fit an alloy plate over the schottel under slight tension to stop the top cog lifting and slipping .
Rubbing strips are fitted to the bottom just for added protection as this is a foam boat , and a coat of paint applied , this will have to be left a couple of days to dry and soak in .

I have managed to get a couple of close up's of the foam , to give you an idea of what the material is.
This stuff can be cut and bent very easy, but has a good resistance to impact

what an interesting building material, though it may need the roof of a cathedral to get her down to the waterline, where most use a mere chapel !

Perhaps a shallower angle on the keel rise at the stern...

I am wondering if it will have problems with reverse thrust vectors... {:-{

Your words could not be more accurate  sir , i had to put 6 12v 7ah's and some little 2ah bats in it just to get the prop in the water .
Then the little drive just did not have the power to move the lump around in a forwards direction .
Yhis project has since been stripped and binned , but it was fun  :-)) which is what the hoby is all about.

Oh yes , big time . But still we live and learn ,
once i had removed all the drive components etc a few well placed size 11's sorted it out for the wheely bin.
I still have plenty of foam sheet left so who knows what will be next , maybe a hovercraft type thingy swamp boat .
Too much time, not enough thought  :-)) .
