Re: '78 Ebko Lebaron - Therapy
OK, I didn't do anything but clean up my messy work area last night. Rearranged the shed so I can pull out large quantities of glass easier.
Did a lot of thinking and have a dilemma or two...hope someone can point me in the right direction.
Item #1
Water in the Foam...
I have put a lot of thought into the escapement for water under the deck. When I first started the project I was convinced water would never be able to get under deck. With the months of reading I now know that I still must plan for it. That is why I have limber holes in every section (still have a few more to put in after doing the gussets). Down the "V" bow to stern I have limber holes in all the bulkheads. a couple of these will have foam going in, like under the tank. I can put a piece of PVC or hose in there to connect the bulkheads, but I still need water to get from the compartments made by the stringers into this foam filled area and what ever type of connector I use. I also will need something to leave a path for water from the outside of stringers into the "V". I have holes but do I need a channel along the base of the stringers too? I have seen/heard different ideas on how to go about this, but have not seen evidence that anyone used the methods they explained. For instance I have heard of using balloons ( I doubt that would work), cardboard tubes (sounds good in theory), garden hose. PVC pipe cut in half with holes drilled in it. I have also considered a perforated drainage pipe type system. Problem is the foam will find a way into al the perforations, I'm sure.
One other idea I had I put to the test last night. The poly foam will not stick to slick plastic..so....I thought ...vinyl tubing is slick. I made a very small batch of 2PF. poured it over a small 3/8" piece of vinyl tubing I had laying around. Let it set up. it was stuck pretty good. I could not pull it through the foam. I could however peel it from the tubing. It indeed did not stick to the tubing completely. So I thought...Needs lubricant... I had some 3in1 oil close by repeated my experiment. Was actually worse. I could not pull the tubing free, nor could I peel the foam from it. So back to the drawing board. Now I start thinking about putting air pressure in the tubing to expand it, then let the energy built into the wall of the tubing work to my advantage. With a large diameter tube I think this might work. I will try and test it this week sometime. But then...I think what about a bike inner tube? cut it so it is straight, seal it on the ends...fill it with enough air to make my mold then put in the foam, remove the air and pull it out? May try that experiment as well. If anyone has already done this, let me know.
Item#2
Motor Mounts
You may recall I have fashioned a set of motor mounts. Was a slow day when I did them, did not have anything solid in the hull yet. Just going with numbers I had jotted down on some paper. Well..those of you who have been watcing me for awhile remember that I did the same thing when I cut my first stringers....too short...doh!!!
These mounts are too narrow. I need to have 24" on center ...my stringer faces are 32" apart. I cut these things 5" wide. that leaves me with 27" centers...and I need 24"...do I put spacers behind them, then glass them to stringer/hull as planned? Or do I remake them?
