Infusion Q&A

what about using carbon on wood for stringers

 

several layers of tweel k12 carbon with VE

 

Boats can stand more that people can so build to last !!!
Like i have drawn the details are really importnant . the coved corner wil flex and if the corner is to sharp the layers of glass delaminate , the gelcoat will need to be gound off where the glueing takes place because the glue is strong enough to tear the gelcoat off the glass . the cover strip out side and the hinge strip inside are vital !!!. have seen tubes completely come loose off the hull because of no hinge strip inside and the tube peeled off from end to end !! very scary when you a few miles off shore in mountainous seas . The lay up of triaxle glass looks like over kill but believe me in the face of an rib hitting a big wave at hi speed the tubes have unimagionable lifting force . enough to compress you spine and break legs if you are not standing ready or sitting properly . the triaxle is worked in amongst your standard layup of the hull that should be feathered out as it goes up from the chine so just the triaxle glass goes to the top and round the corner . the chine i where you floor inside needs to sit and be attached not only bonded but glassed over as well ! Ribs are something else !!! monos done have a patch on what a rib hull will have to with stand . be carefull injecting foam its better for a hull to be a little flexable the withstand the enormous pounding that it will endure than to fill with foam and have it come lose later and have to cut the floor open to dig it out !! foam under floor in my book is a no no !!.

AS well as the picture with information for you to study theres a copy of my work referance when i left the company just to confirm my work esperiance at the inflatable company .
To this day Dudly is a personal friend and have know each other for long time . if you want any info about building tubes theres a phone number there just add 0064 in front and phone him !,he is retired as i should be !!
Always here to help !!

 

i was thinking of D ring tubes foam filled in this way i will raise sides and build sides for floor as well so as to bond both hull side wall and floor side wall and use both as backing wall fr D ring

 

i am using a 33zf donzi hull from the 80s as my plug

 

i am thinking of using old bertram hulls for plugs fr ribs 25-31-38-44 ft

 

or maybe old magnums !!!!!!!!!!!

 

In these types of boats carbon and kevlar have no place they are exstreme products and for durability mixed with glasses wont last .
Its time you got familiar with the properties and the use of Unidirectionall glass combined with vinylester resins !! no need for epoxies !!

 

thanks for your advise and help and your keen assistance highly appreciated

 

Be careful. Here splashing, stealing someone else's hull design, is heavily frowned upon.

 

s and r glass of owens corning is no good either?
