Poetic License:


Might I be excused for a bit of poetic license for whilst the flavor of the Demolisher cannon is still intact, the oversized dimensions required a bit more detail.

The photos reveals that my work isn't very symmetrical but it will do.

Onward to the trunnion mount...........

Truncated Trunnion Mounts:


Or as I call it, "An exercise in perseverance."

I started with five 1,0 MM discs (Same as the one pictured here) and glued them together with the plastic cement (red labeled tube above the disc.


When dried I rough sanded the edge of the stack round.


I then penciled a smaller circle so I had a line I could sand down to taking care not to cut into the larger diameter outer disc edge.


Progressing from rough sandpaper, to file, to diamond emery file, until the bevel is smooth; perhaps 10 to 15 minutes of filing.


I then gave the edge a coat of Tamiya Extra Thin Cement and set aside to dry.

Thanks,

Sponsons:


First order of business is the sponsons and turrets are too small. When I first set up this model I had nothing but my unpracticed eye to rely on and my best guess was correct as far as an original Baneblade sponson housing and turret but woefully inadequate for the oversized beast this has become.

My newest sized turret figures to 22 MM in height and 25 MM in diameter.


Never the less, the rotation mechanism remains the same starting with a fixed dowel secured with an axle screw, a piece of PVC tubing for the rotation sleeve and a styrene veneer for a base material to adhere the detail.

Cooling Exhaust Vents:


The muzzle brakes or cooling exhaust ports at the mouth of the cannon; 16 precise drilled holes about the periphery.


Somehow I managed this all those years ago but for the life of me I cannot remember how I did it?

So I'm inventing a new procedure cutting a drilling the holes into 0.020 styrene sheeting.

We'll see how this works out...........

Thx,


Two Methods:


Drilling the holes in the muzzle ring is exacting work and if you use a pin drill bit there is a tendency that either the bit will break or it will walk to the edge and ruin the work.

In my previous post I showed my first inclination on making these holes; i.e. marking the positions and drilling the holes with the tip of a # 11 Xacto knife blade used as an auger. This fulfills two purposes in that it give a very fine point pilot hole plus the stability of a much wider bit so there is less tendency for the tip to snap off. After augering the hole on the marked side I flipped the work and reamed the obverse side as well to give a more straight sided appearing hole.


The second method I came up with (The barrel on the left side of the picture) I marked and cut out the overlay disc and tack glued to a section of half inch 'Evergreen' tubing, drilled pilot holes with the Xacto blade as before, inserted a length of 7/16 inch tubing and trimmed the outer edge of the disc with a curved emery file. I then cut out the bore diameter from the disc and flied smooth with a curved needle file.


When completely shaped I sliced off the disc from the half inch tube and sanded the residual glue from the obverse side and reamed as before.


I then glued the finished work to the barrel muzzle.


Either way is equally simple and the result seems acceptable.

Thanks for the reply....

Keeping It Simple:


I have a miniature drill index and it's around here somewhere but I rarely these days have a use for it.


I find the #11 Xacto blade provides for almost all my fine drill hole needs. especially when as in this case you are working on a disc barely a half inch in diameter.

As stated above the fine point acts as an adequate pilot hole drill and the tapered tip enlarges the requisite hole to any reasonable diameter.

After that you can utilize the same blade to carve out larger holes as I shall be doing when I finish the bore on this, the Demolisher cannon.


The added beauty of using this blade is with a fine file it can be resharpened.

You're welcome.....

Preliminaries Dispensed with:


Okay so with the preliminaries dispensed with we can get to the actual plotting and boring of these holes finding the center, erecting the perpendicular axis by employing the arc and straightedge and compass technique and subdividing by eye the quarters into 16 more or less equal divisions which is the number of cooling ports in the typical Baneblade muzzle.

Below we see the 0.020 inch thick disc glued to the end of the muzzle slightly oversized to allow for the frail nature of the constructed holed disc.

Below the finished rim sanded and accented with graphite to show the relief of the 16 muzzle ports.

And finally the main armament in place on the hull displaying a nice added touch to the overall basic detail of the model.

Twice As Voluminous:


I held off as long as I could but ultimately I decided the side sponsons were just too small for a tank of this magnitude. What armament I choose is still in the idea stage but the sponsons will be twice as voluminous as those on the standard Baneblade.

Dangling preposition:


Or what's a Heaven for?


Framing the sponson appendages to bulk out the size is a daunting task when under the influence of a triple Martini That's eight and a half ounces of the finest kind (Really the cheap stuff at a £ a liter) but none the less having a go at model building at 3 sheets is a bit of a no, no so anyway as long as I can work the keys I'll persevere.


As stated before the bulk of the sponsons is deemed inadequate and the necessary adjustments are in place and soon the work shall continue apace.

One of the beauties of scratchbuilding is if you don't like what you see , change it.......

New sponson size is much more in fitting with the size of this beast BA, wouldn't have known of the martini influence from the work you've shown:smile-big:

Most Gratifying:


Domestic tranquility; this week the washer leaked and soaked the bedroom carpet. The stand pipe was compromised and the drain tube too short all of which promulgated "arse holes and elbows" corrective measures to resolve the incident; fortunately the Blackadder prevailed and the situation was set to rights and he celebrated with a "Kraken Blast" and managed to also increase his effort on the Landkreuzer (subsequently dubbed "The Kraken")

"Any who" the Sponsons continued apace and seem rather adequate considering the travails your's truly suffered at the hand of fickle fate; bringing you the latest update of this monumental project.

I like these Sponsons much better than my original iteration.
