Title: replacing bunks in CP 16 (79)
Post by: WhiteShad-O on December 26, 2012, 11:13:56 PM
My bunks are dried out, but rotton.  I see know way of getting them out in anything better than many pieces and propbaly some wood dirt.
What type of wood, or other core material would be both cost effective and effection as a means of replacing these?  I am planning on covering the entire wood with epoxied cloth unless I can constrect them above board in an open area, then I  would use polyester resin cause its cheaper.

Any pointers here would be apprecaited or I'll just use my fiberglass knowliedge to do what I think makes sense.  do I have to be concerned with creating a hard spot where the tabbing is done to attache the bunk (s) to the hull?

Will 3/16 inch ply covered both sides with 10oz cloth and resin provide adequate strenght?  Do I need to step it up to something like 5/8" which seems a little stout?

Thanks,

Pressure treated 2x4's work well.  Secure to trailer with galvanized bolts.    Cover with outdoor carpet, no resin

I agree with Mandolin, It is simple, and works for a long time. 

You dont even have to carpet them, but it makes it nice :)

By glassing em, you could potentially miss a spot and cause them to rot faster, not to mention that it will make em less able to flex to the hull shape somewhat.

One could use some of those 2 x 4 or 2 x 6 plastic boards made out of ground up and remolded milk bottles. Would not even need a carpet. And talk about slippery and flexibility...why it's almost like at the circus where "she walks, she talks, she crawls on her belly like a reptile."

skip.

Cycle is right........ LOL

I read his post a few times over before I made a answer, and somehow still missed it......

It sounds like White Shad-O is on the right Idea, but what I would do is replace with same size thickness plywood as to not have the boat structure changed. Sure, adding glass will strengthen it up, but may not provide the same structure as the wood did originally.

Tabbing into the boat shouldnt create hard spots unlike the original as it is made that way on purpose.
