I have decided to jump in with the Steampunk trials... looks like a lot of fun. I have decided to name her the SMS Krieger... I am using the wonderful plans made by Steve. Very nice job in the planning. I first made a trip to my local print shop and had a set of plans printed out. 9.00 bucks Then the wood from my local WoodCrafters at 40.00. I have one 48" x 36" x 1/4" 5 ply and one 48" x 36" x 1/8" 3 ply I then traced the hull pattern onto the needed thickness of sheets. IE. I have two 1/4" outlines and two 1/8" outlines. I then cut them out and left the inside uncut for later. This way I can screw all the pieces together minus the top cap, and sand the edges all smooth and exactly the same. I then cut out the notches on my router table while all the "plates" were still held together. This way all the notches are also exactly the same. For a larger view click here! For a larger view click here! Then I cut and milled out all the rib pieces. The measure 1/4" thick, 4 1/4" tall and 1" wide. I drilled all the holes for the wire runs and cut the notches needed. All these were done in groups so they are exactly the same. For a larger view click here! For a larger view click here! Then it's time for a dry fitting of all the parts.... For a larger view click here! For a larger view click here! For a larger view click here! For a larger view click here! All the peices are fitting together nice. For a larger view click here! Now on to the stern area before glueing up the pieces.
Your a beast! Is that the AC or BB? FYI, since you're not using the 3/4" water channel layer, you will lose structural integrity if you plan on the 1/2" radius on the bottom. ST
That's so purty... But I do see a couple of worrisome items. This hull is about the same length / beam as my 1:144 Baden, but the hull is 2x deeper.: 1) Displacement weight: To get this cruiser to waterline will require about 50 POUNDS of weight. Don't wanna think about the BB. 2) Propulsion: Moving that deep-drought, heavy, blunt displacement hull with a 1 3/4" plastic prop? We were shooting for 26 seconds, right? I'm worried about getting enough thrust to counter wind drift, let alone maneuver. Ain't no way that prop will get that hull to 26 seconds
Draft is 3" which is scale for the era. Remember that these first hulls are being built to spec with a minimum of the required 1 1/4" freeboard so the draft looks a bit skewed in these pics. The intent is for builders to customize above the 1" pen area. They can add height, flare, tumblhome as desired. If doing so, the design will look more balanced. As far as performance, I'd like to limit the hulls built until we can get some in water testing. Steve
No worries on the scale Steve, I understand the intent. Just hadn't internalized what the bump in scale vice 1:144 would do to ship weights. The hulls will look much more proportionate once they're "built out". The performance issues are the ones I forsee needing to tweak rules on. Either the spec prop or speeds will probably have to change. Maybe even redesign to twin-screw layouts. But like you said, early days. We should have 4-6 hulls (mostly AC's, 1 or 2 BB's) ready for water testing within a few weeks.
AC... I will be putting a 1" water channel tonight. It will actualy be two 1/2" pieces. The top 1/2" layer will also have cut outs for batteries and CO2 bottle ect.... That will stiffen her up when I put a radious on the edge. I do see something we need to discuss this weekend.... the props! ugh... When I post up stern shots, you will see where I extended the stern piece by one rib to give it something to strenghten it with.
BAH HUMBUG, build baby build! If it needs changing too much, it can be used as firewood for the brats and BEER :blink: OFF to the workshop I go..... If anybody would like to watch me build via skype? My user name is McSpuds, send me a invite and jump on skype...
Did you modify the stern where the prop goes to be shorter than the top pieces? That's a change that was made that was not on the plans you got, to make room for the rudder operating mechanism. You can fix it at the build session before you glue up The water channel pieces add a LOT of strength. Enough that I decided that I didn't need the 2 full-width frames for stability that I was planning. It's a beast. I'm only putting one 6V 12AH battery in (right now, anyway), it shouldn't need more than that power-wise, although ballast-wise, I'm thinking it'll weigh like 30-ish pounds to get to waterline. It's about the same size as my I-boat, but deeper below the water.
The spec prop is either 1.75 or 2". We'll see how it does in the water. My ship is close enough that we could conceivably float test it and drive it around the pool this weekend to see how it does with the spec prop. If that's not good enough then we'll shift fire
Phil from Vac-U-Tug will be at the lake this weekend, let me know if you have any questions or need something.
No external modifications... I extended the piece that the rudder servo sits on... it was extended towards the bow by one rib so I could attach the plate to a full rib... When I get home after class today I will post up a shot.
The size should be fine.. 1.75 will get her around, maybe not at 24 sec..LOL My concern is buying a certain prop from a certain vendor. I would suggest letting builders get props from whoever as long as the prop was no more than 1.75 dia. The ones from vacu boat are nice and cheap... but builders should have a little more choice on the prop, at least in material and who they get it from..
We'll drive mine around and see how we like it. The VAC-U-boat prop might not have enough blade area to get her moving, but we'll see. If you like, we can also try a 1.75" BC prop to see how they compare. Assuming build time permits
I have a shaft made already to replace the threaded one from Vac... We can change out real fast and I have a good assortment of props on hand. I am also cutting out a template for the BB profile that is being worked up... just to compare size up front... she's nice..!
Greetings: It is hard to determine the size of the vessel. What is the length and the beam ? Manuel Mejia, Jr.
