Hey Steve, part of this for me is an experiment in pushing limits which I enjoy doing. This is the biggest sub I have printed so far so I am looking to see just how strong I can make the hull at this scale. Thank you for the compliments on my Thresher. It is a personal favorite of mine.Comment

Hey Casey, I have so much going on that I will be just trying to get it painted by then. The Oberon I have been working on is now done so my next order of business is to get Vaughn his Typhoon and I still have a few things I have to do to prepare for Subfest.👍 1Comment

Just to put things into perspective. Started June 4th. The build surface is an interior hollow core door. About half of this is actually tweaked and glued together (from the bow to the sanding marks). The bow is just taped on as it will be glued to the upper hull. There are two more stern parts to print for the lower hull. The propulsor shroud will need a minor mod to make it removable. Dang I need another Ender 5+.

Your "Jimmy Carter" is really going to be spectacular! It's presents in the water will really be something to see! What you are doing with 3D printing is to be admired, and you have certainly taken the process to new heights for sure! Nobody in this hobby admires and respects the masters more than I do, those that built subs using skills and talents that brought this hobby to what it is today! It's my opinion that 3D printing will be the new wave of the future for this hobby, and it will only get better with new tech-knowledge and materials to work with.
Steve! You are at forefront of this new tech-knowledge, keep up the great work you are doing!! :-))

The hull bottom is almost completely glued together and it is shaping up nicely. I will bolt the stern to the hull using threaded inserts allowing it to be removable. I had to make a slight change to the forward propulsor ring to extend the flange in order to allow for small screws to secure the aft shroud. I also designed a new shroud as the Jimmy Carter's is longer than the regular Seawolf. As a result I also designed a new impeller very similar to my Columbia to fit it. All together it nets out at 113" as expected which will just fit in the middle of my trailer.
The CF tubes installed to strengthen the hull. I will do the same with the top.
Close up of the same where the extension is located with my custom tube anchors.
The stock holes in the flanges helped to position and align everything as straight as possible. Its almost time to make a cradle for it.

Yeah, it's big. Probably about as big as I can take one depending on the files. I will have to come up with something to launch it at the lake but I have an idea.Comment

Sail and bow planes are printed and fit nicely.
Stern planes and rudder are printed as well. One thing to note. The stern planes as designed were about 3" long each. Not much surface area for a 113" long boat. I have the Trumpeter 1/144 plastic model of the Seawolf and based on it the stern planes were full span so with a slight modification using a coping saw and a redesign of the planes in Fusion 360 it will be easy to change and add about 1-1/2" to the length of each plane.
Port side has been modified. Starboard has not for comparison.
The propulsor shroud mounting flange is bolted on with M4 screws and threaded brass inserts as well as the whole tail piece to make it easier to connect linkages and such.
I make all my boats with removable sections where needed to ease servicing because eventually it will need to be done.Last edited by SubDude; 07-31-2022, 11:00 PM.Comment
