SARP Stabilized Advanced Remote Weapon Platform;

As we approach the main armament mount ( A bit earlier than I intended. It would be a good idea to make sure the the 'guns' clear the hip joints.) there has been some speculation as to the functionality of the yoke arm hydraulic system.

I did some research into 'SARP Stabilized Advanced Remote Weapon Platform' and found some interesting tidbits.

First of all the SARP appears to be a linear system i.e. in line with the gun barrel

Linear Elevation/Stabilization Drive:


so this eliminates the hydraulics as a gyroscopic stabilizer as the arm is perpendicular to the barrels besides raising the whole arm is much too massive an undertaking for something as sensitive as ground affect stablization. The hydraulics of that size could not respond quick enough.

Second there has been some criticism of the trunnion mount of the main gun. Accidentally or purposefully the author's (Joazzz) trunnion mount works well with the stabilizer system:



albeit sufficiently built up to Emperor Titan scale.
and so we're back to the intended purpose of the Hydraulic actuated arm.

I have really got to get a life.

This is life. The rest is just filler,

A week Of Detailing:

A week of detailing and while gratifying that so much was accomplished now that it is all back together it doesn't seem like all that much.

This first image shows the Yoke detail where the hydraulics will mount on the arm extenders.

Pretty much the same shot from a lower angle.

Time for a celebratory cognac and coffee.

Absolutely breath taking work. I look forward to watching your continued progress.

Also, it's a shame you don't play 40k. I would love to see your titans in an apoc battle.

My son is still active in 40K wargaming but hasn't played any of the titans I have made or built I suspect for the sheer size and strength of the pieces. The pieces are just too powerful. I'll ask him now there is the potential for a second Battle titan if the two could clash on different sides. After all, the Warlord per se does not have to be affiliated with the Imperium but could be Chaos; to my mind anyway unless I am off base as to the mechanics of the game.

As I have stated on other occasions, my idea of wargaming is chess which is quite complex enough for my aging brain.

Finally:

Now that the yoke is roughed out I can devote time to the interior levels of the engineering decks. A spot dear to my heart as I am a frustrated engineer or at least pretend to be on the internet.

Below is the slide out deck of the first engineering level cut and ready to insert into the lower hull.


https://i.imgur.com/ElZ4BTy.jpg


And that deck temporarily in place for adjustment.

https://i.imgur.com/TMargRP.jpg


I plan to have the Fusion Reactor on these levels as in my Warlord which will take up the lion's share of the space. There will be one sub deck, three engineering decks and an egress to the command bridge (head) plus the altar and various religious accoutrements to the Omnissiah.

What're your vertical supports going to be? That Yoke's gotta have some hefty pillarage going down to the hip bones.

Jeez What a Mess:

All the sub components are just locked in place with interlocking tabs and while I know where the pieces actually go, the stability of the structures is tenuous at best.

Below we see the inner levels decks 2 through 4 deck 1 being done earlier this Summer. Decks 3 and 4 frame the yoke and have yet to receive their floors.

https://i.imgur.com/yVbqA9Z.jpg


I have not worked out how they will be removable and how the neck will intersect with the third deck flooring. Some sort of bull nosed staircase I imagine. It will all look rather techish and decadent as befitting a titan interior but I have plans for an altar structure with attendant priests as in the Warlord.

https://i.imgur.com/hJtQNPy.jpg


Above we see looking down at deck 2 and the two angled walls that will support the yoke and underside of the superstructure deck again rather sparsely connected without glue or screws so it all appears quite a jumble at the moment.

https://i.imgur.com/nnHxaDO.jpg


The side view looking rather cleaner.

https://i.imgur.com/fr57fNz.jpg


With the superstructure deck reinstalled the whole thing begins to tie together (Note that the jaw has disconnected for the visor) but all the rest of the components locking into their respective locations with barely a millimeter discrepancy that I can measure. Much of the precision purely by luck I assure you.

And the right side view of this hodgepodge.

A Series Of Interlocking Components:

It took a bit of doing but all the major components lock together to go from this .........

https://i.imgur.com/I4QDhMm.jpg


To this .......

https://i.imgur.com/S7OFsf2.jpg


in about as much time as it takes (me) to type this. (Not being the world's fastest typist.)

https://i.imgur.com/0OHMIvq.jpg


So the entire model thus far can be disassembled for painting, upgrading and repaired at a whim.

https://i.imgur.com/lBdAkHK.jpg


Now that the superstructure deck support is locked into place I can continue with the interior with the intermediate deck roughed in in the immediate above view.

https://i.imgur.com/f9Ho6TC.jpg


With the deck removed you can visualize the two story engineering compartment.

Lookin' good as always.

You amaze me Blackadder

Desperation Is the Mother Of Invention:

I won't boor you with the details of how I made these plugs. The first view should be self explanatory

https://i.imgur.com/TlWNUhX.jpg


Instead I'll boor you with the why.

I've got these two side supports that will ultimately hold up the tophamper

[BTW I weighed this beast this weekend and excluding the vise he weighs 12 pounds, (5.44311 Kilograms),(0.857143 stone), Twelve Pounds of STYRENE!]

Anyway that much weight will surely spread these walls especially since I will not be gluing them in place (I hope) so the problem is how do I lock them in place.

Once again the waffle light panel to the rescue.

https://i.imgur.com/N29ODWw.jpg


I made plugs that will fit snugly into the waffle recesses.

https://i.imgur.com/heklFqn.jpg


Naturally it would have been too much to expect that they would line up perfectly with the overhead deck so I attached a fudge factor plate to compensate for the misalignment. and glued the plug to the top of the side wall. (I won't go in to how exacting this was; especially for the first one )

https://i.imgur.com/uhZpelq.jpg


Three more to go and I'll display the finished assembly.

Looking good!

Fallen Into Place:

The four aligning plugs installed.

https://i.imgur.com/rkcrhfD.jpg


Sorry for what appears to be repetitive images but there are the subtlest differences that entailed a lot of work that I feel I must apprise anyone following this thread aware. The aligning of the upper deck is most important for subsequent structures otherwise the model will become lopsided and sloppy.

https://i.imgur.com/FGxgtbZ.jpg


Note in particular the centering of the weapon yoke in the slot. Now that the sides are secure that arm is correctly brought to center.

https://i.imgur.com/NXLTpPz.jpg


Now that the side panels are locked into place with the upper deck and the chest area I can proceed with the building of the interior and the rear of the titan.

I love your use of the lattice structure everywhere. Instantly made me think of the lower decks on a military ship.

Thanks for the reply. What are you up to lately?

A Weekend's Effort:

Aside from my official duties I managed to find time to add some detail to this beast and attempt to refine a vexing discrepancy in my calculations. Note the adjustment of the cylinder trunnions.

https://i.imgur.com/uqAkjMb.jpg


I still have to mount the magnets that will secure the piston end of the assemblies but I know I shall have to adjust the gap between the piston head and the armament yoke; hence the cutouts.

https://i.imgur.com/WwKrLCw.jpg


I still question the necessity for these hydraulics as they corrupt the clean lines of the model but I'll install the for the time being just to remain true to the prototype. The work will not be in vain as these cylinders can easily be adapted for the legs or ankles.

I wish my local hobby shops stocked as much evergreen as you've got there Mr B!! Incredible work so far, as usual.

You could ask or you could order. That's what I do especially for unpopular items. When I first started out in this hobby I approached these Evergreen racks with my tongue hanging out. They seemed so expensive (They average $3.80 a sleeve now and I've got over a hundred sleeves of various sizes.) But I set myself a goal of buying a couple of sleeves a week of the most used sizes. soon I had all the 'strips' sleeves and rods and tubes. In less that a year I had all the necessary sizes and variations. I now spend $20 bucks every few months to maintain my supply and if I have money left over I treat myself to some of the more esoteric variants like Plastruct box beams, I beams, L angles.

I've mentioned before I buy my sheets 0.020, 0.030, 0.040 styrene at the local Industrial Park plastic wholesale warehouse and I discovered the waffle lenses for fluorescent 48 inch lights. that is a boon to scratch building. I scrounged an old wide screen picture tube TV the other day. The case was black poly styrene and I'll be using the air vents later on in this build for ready made louvers and what have you.

HTH.

EB.

Whoops! I just saw you're in Papua New Guinea! Kind of a bit off of the beaten track but still your hobby dealers have to get their material from somewhere and have to reorder on occasion. Tell 'em what you are trying to do and I'm sure if they are not total asshats they'll help you get the material you need. If they've got some Evergreen, they've got a source for more.

Dude, All you've got is Theodist Ltd??? Can you buy on AMAZON or EBAY?

I pretty much spend my time wishing I could be working on projects like you do. I graduated last year and have been looking (rather unsuccessfully) for an engineering job. I have a nice prospect I'm flying out to interview with on Monday, so fingers crossed. Then once I have money I can begin building mini things again. Seriously, I want to follow you on this one and build as you build (like you suggested), I guess depending on how things go over the next couple months, I might catch up (luckily you have other priorities and don't build these things overnight).

Good luck with the interview. We're all pulling for you I'm sure.

When You.....Can Look.....Like This:

I wasn't satisfied how the piston/snubbers/whatever, detracted from the sweeping elegance of the armament yoke yet rather than discard the whole concept I decided to play around a little.....

Aesthetically this looks better to me.

https://i.imgur.com/NJAn2og.jpg


When you are going tohave hydraulic systems that serve no apparent purpose, at least they should look good; Right?

Oh my goodness that glorious plastic wall.

Interesting solution. Any chance of a zoomed out pic with that? I think we need a pic of your plastic wall as well.

Request complied but no spanking.

It took a bit to tidy up; I even swept the floor.

So basically this is my cubicle ah sanctum sanctorum.

https://i.imgur.com/KGohg9B.jpg


Enjoy,

I see what you mean, it does change quite a bit. Have you thought about moving the point where it connects to the Titan further up, to where it is fully vertical instead of on the angled bit? That might enhance the lines of the yolk instead of draw from it.

Wow, it's amazing watching this titan come together.

Also, good luck with your job interview jabbakahut!

F=PxA, figure out how much power you actually get scaled. Although I get where you’re coming from, I don’t think you’re gaining anything by moving it to the center. I don’t find them to obscure much, especially when you take a step back and look at the bigger picture. In fact I like see them more prominent than hidden, I want to see the actuators. If you need more technical reasoning... maybe they need to be dual for a back-up? Or splitting the force on either side of the yoke helps keep the axis of movement inline with the body?

Back-ups of a part of the titan that’s so exposed sounds like a good plan if you don’t think about it too much, but really just highlights how inefficiently designed titans are. I think your latter justification works better.

I did it for aesthetics plan and simple. I like the way the dual cylinders look centrally mounted. It's the difference between the Iowa class battleships and the KGV Class.

Been watching the progress and as ever, I'm awed by your work. I'll just say that I prefer the exposed look of the pistons - and once you get the weapon arms and connectors on they'll blend right in -especially once painted (or covered with aluminium powder). However, you're the master engineer on the project and I bow to your expertise and vision....

The wall of styrene is almost as impressive as the Titan.

Cheers,
