The next step in this adventure was to work with the propullsors. Using advanced country triangulation, I located the position that I wanted to install the WTC. I wanted to keep the angle of the drive shafts manageable so after measuring the angle of the dangle I came to the conclusion that the propullsors needed to go about,,,,,,,,,,,, right,,,,,,,,,,,, here.Therfore they were glued in place as you see them here.
Because there are so many different possibilitys for dive systems Rick doesnt give you assigned locations for componants. Its up to you to choose what systems that you are going to use and the way you are going to implement them.As you can see the opening of the propullsor cavity of the nacelle is completely open to the inside of the hull. As a consequence of that you would have no reverse. So to rectify this I made out of sheet plastic a cover to block off the opening, as you can see here.
However in order to get reverse I had to open up some scoops for the water to get in to feed the impellors for forward and to create an exit for the water for reverse.So I created a scoop above and below the longitudinal fin that runs down the middle of the hull from end to end. It took a lot of cutting , filing and smoothing to satisfy me.
While we are on the subject ,Warren Wilson was the first person to look at this sub at a subrun in georgia and suggest to me that I would have problems with this setup because the scoops in the front were smaller than the opening in the back. Smart man! And as it turned out he was right. After several test runs in my pool I found that it was starving for water in forward. So this is what I did about it.
As you can see I drilled holes in the bottom of the nacelles to admit more water. Initially I was worried that I would lose efficiency in reverse but that hasnt proved to be true.In time im going to shape those holes into ported slots to channel the water.Well thats it for now dudes. See you next time.
There are OLD pilots and there are BOLD pilots but there are very few OLD BOLD pilots. MAG
