    Snow Bound:

    So to while away the weather front I did some work on the neck which I have to admit is coming out better than expected. I sheathed the coupling on 0.040 thousandths styrene to three layers and then proceeded to bevel the rear edges 45° as in the drawing.

    As you can see below there is quite a bit of cutting to get the 45° bevel in the front edge ............

    but my 'Farmers file' was up to the task.

    The forward bevel needs to be refined but is okay for the moment while I make the inner neck mechanism so the head can be tilted down. My previous Warlord has this capability but the mechanism is very clunky and I am hoping to refine it on this model.

    Finally I found this collar that will work very well in the scheme I have in mind for the side to side movement of the head and fits into the Emperor design quite well.

    Can anyone guess the source of this wondeous bit of sculpting?

    Snow days are always good days to work on projects.

    Is it a plastic/paper bowl?

    Close, a 5.3 ounce Shoprite yogurt container. I plan to use a lot of recyclable plastic in the manufacture of this model.How well I succeed remains to be seen.

    I do something similar in my projects. I use old pringlez cans and oatmeal containers to make pipe ways and storage tanks.

    2D vs 3D

    I'm getting way ahead of myself with this head assembly so I put the brakes on to pitch an update. After scraping my initial idea of how the head assembly can tip forward on the neck I came up with this solution which will give me a lot more cockpit room for the crew. There also is a poetic license taken by the artist who drew the front and side reliefs of the Command Bridge. The huge ear discs that contain the head tilting mechanism cannot function as drawn and are of different sizes in the drawing. Never mind though, I have a solution.

    I'll start with cutting the forward neck ring to allow the discs to mount flat to the sides of the neck.

    http://i.imgur.com/mvwGHMu.jpg


    Carving out an outer race for the gimbal head mount pad and gluing on the gimbal bases is what is shown here. The two 0.040th inch discs are 71 MM apart and 56 MM in diameter.

    http://i.imgur.com/gkvcxbH.jpg


    The bridge truss maintains the distance and keeps the gimbals square to each other and stabilizes the bases

    Next, the manufacture of the gimbals mounts. (The area left black in the 2D drawing.)

    Gimbals:

    Or Trunnions whatever, These truncated discs will support the head on the neck to allow it to look down in a purely theatrical way as a downward pointing camera would be just as effective but the menace of this skull staring down at it's victim is too good to pass up.

    http://i.imgur.com/TxBpE0G.jpg


    Above; the disc is a simple truncated construct featuring two circles 45,0 and 54,0 MM separated by 2,0 MM by 4,8 MM styrene spacers.

    http://i.imgur.com/fIfj5Yf.jpg


    Unfortunately I got the angle wrong so I have to re-sheath the bevel but that's not a big deal.

    http://i.imgur.com/J7JtoOQ.jpg


    Tomorrow I hope to be working on the cockpit.

    The Visor:

    Allowing for the helmet I mounted the gimbals with extended visor mounts made of 0.015 thousandths sheet styrene. As I don't really have a plan for the cockpit, chin or gullet piece all this is subject to change but at least now I understand how the cheek pieces work with the gimbals.

    http://i.imgur.com/dybKoJX.jpg


    I suppose the best thing is to cut the helmet to see where it falls in relation to the ears (gimbals) and the amount of clearance required to allow the head to lower and raise.

    http://i.imgur.com/LEecGev.jpg


    Somehow I managed to guess right which moving part eclipses which and for that I am grateful.

    http://i.imgur.com/a8ra21q.jpg


    Later on this evening I'll cut the helmet but I need to relax a bit after this thoroughly draining exercise in design. Martini Time!!!!!

    Helmet:

    My initial thought was to use a suitably shaped bottle to form the helmet but after experimentation I found that was unsatisfactory for my obsessive compulsive mindset. I opted instead for building up the helmet out of stratified layers of styrene and cutting the helmet out of the resulting block in much the same manner as I did for my Warlord Titan

    http://i.imgur.com/gxEB51B.jpg


    This also relieves me of the necessity of finding a suitable glue for mating the different sources of plastic......

    http://i.imgur.com/uAIDHK3l.jpg


    It's bad enough that I had already go through the identical thought processes in making my Warlord but to have not learned for my previous effort defies logic.

    Ready To Begin Shaping:

    The layering is complete and all needs be done is the shaping

    http://i.imgur.com/aK44D0O.jpg


    I made the helmet about an eighth inch over sized per inch to allow for carving and sanding

    http://i.imgur.com/axEuWUo.jpg


    Tomorrow I should be well along on the paring down to the rough dimensions.

    First and Second Contour Cuts:

    Most of which are done on a stationary belt sander.

    http://i.imgur.com/7RO8KiC.jpg


    One more preliminary contour cut to make.....

    http://i.imgur.com/SVQpT3F.jpg


    The sides have to be rough sanded at about 45° before the finishing contour sanding.

    Rough Shaping:

    Final rough shaping involves truing up the block to 90° then cutting a 45° bevel each side and finally two 22.5° bevels each side on top and sides.

    http://i.imgur.com/9DUyTiT.jpg


    Next (and this is the tricky part because it takes a bit of an eye for roundness) sanding off the excess in a controlled arc movement on the sanding belt.

    http://i.imgur.com/bdNKxBZ.jpg

    http://i.imgur.com/W0ZiUMI.jpg


    so the helmet has a slightly flattened ovoid shape in cross section.

    Basic Helmet and Head

    Well it took far more time than I thought but I do finally have the basic helmet cut to size.


    http://i.imgur.com/P1eCper.jpg

    http://i.imgur.com/5egDBeZ.jpg


    The rear view shows how much I cut out of the interior so I can add the under helmet detail when the cockpit is complete. I may still remove a lot of the inside material but for now it's sufficient as the helmet is as fragile as an eggshell with out it's interior framing.


    http://i.imgur.com/n4znz4T.png


    BTW you may have noticed the background image. This is what I am hoping the finished Titan will look like but leaner and longer legs.

    Must admit I was skeptically raising an eyebrow through the build process for that head, but the shape is actually spot on.

    Suffice it to say I am not happy how this helmet is turning out so I am revamping it. Update coming soon.

    Meanwhile:

    I naturally assumed my Warlord crew would fit into an Imperator head but never really checked so while I'm waiting to complete the face shield I just tried them for size.....

    There's plenty of room; even for a Princep and a few attendees And a cadre of Tech Priests as well.

    Now It Can Be Told:

    Now that I have resolved the issue I can reveal why I had to revamp the helmet. It all boiled down to an assumption on my part that the artist drawing the two elevations of the head was a draughtsman. In a proper draught you project lines from one plane to another and ideally there should be a top elevation as well but I accepted the two elevations as sufficient for my 3D rendering. I built my model slightly oversized than the plan as I wanted the 'head' to be larger than my Warlord's head as the finished model will be 10 to 12 inches taller than my Warlord. I blissfully used the side elevation for all my calculations and after laminating all the layers proceeded to sand the contours of the helmet but after the rough sanding was completed I found the helmet dome was significantly flattened.

    http://i.imgur.com/8vAqAXM.jpg


    It did not have the look of the front elevation at all. Needless to say I was extremely disappointed as I had based my interior design and mechanism on the front projection......


    http://i.imgur.com/56WnEFl.jpg


    Rather than scrap the helmet and start afresh I opted to build on the original to increase the height of the dome which is seen in these to images. It was last night that I managed to glue in the compound curved pieces requisite to obtain a smooth contour; the final pieces to be installed later this morning.

    http://i.imgur.com/2QebzHA.jpg


    So with this setback resolved I can continue with the building of the head; my obsessive compulsive integrity intact.

    A Cure for a Rainy Day:

    After a rough rounding sanding I scored the armour panel lines. First with my utility knife. Then with razor saw and finally with xacto keyhole saw blade
    https://www.widgetsupply.com/mm5/gra...in_519x340.jpg

    to widen the gaps between the armour


    http://i.imgur.com/rer2DpT.jpg


    Now the helmet is ready for wet sanding which will hopefully remove the striation lines.

    Now we're back to making the visor.

    Crest:

    The crest seemed a daunting task but after the helmet it was child's play. I began by laminating six layers of 0.030 thousandths styrene last night because 1/4 inch styrene is too expensive and to hard to work with plus 0.030 is what I had on hand.

    I then scribed two lines and equa-spaced the drill points with my vernier calipers.

    I used my #11 Xacto blade to deepen the drill points and hand drilled 1/16" pilot holes for the scallops.


    http://i.imgur.com/I6LWbhV.jpg


    Then I drilled 1/8 inch holes to center the 1/4 inch final holes for the scallops.

    http://i.imgur.com/shluvZ1.jpg


    After drilling the 1/4 inch holes I cut off the excess material and sanded to the appropriate half hole depth.

    This is so impressive. I like to think I can do (or have done) some fun conversions, but this kind of work is far afield from that it leaves me in awe. Can't wait to see the finished head!

    Spear Heads:

    Spear Head ornaments are tedious but worth the effort. There are probably easier ways to make them but I want mine to have a 3D bas-relief so I made mine out of 0.040 thousandths styrene. Below we see one in place on the helmet and the rest in various states of manufacture. When doing something like this I allows make a few extra so I don't have to start from scratch. You never know when you might need a spare.
    Start by making an undersized template (marked 'T'), trace the points on a piece of scrap styrene, cut them out with scissors (yeah it's that simple,) Drill your pilot holes, Cut the corner holes with your; surgical diagonal cutters, Fingernail cutters, Dikes, what-have-you, use your rat tail needle files to make the spade base compare you work to the finished and make the proper adjustments with you, curved nail file and you're done.

    Now do it twelve more times or more........

    See you tomorrow.
