"Turkey feathers". These are the parts around the exhaust cone that can contract by overlaying to reduce the aperture and increase thrust.

First one plotted out. I have no real dimensions on this. I judged the thickness of each based on recognisable objects in some photos. I can adjust as i go. Roughly 20 per engine.

One turkey feather to completion. Primer grey, aluminium silver overcoat, light spray of black over the top for that burnt, carbon-scored look.

Mass production begins.

I have lots of concurrent activities going on now to make the most of any spare time I have.


While I am working on the exhaust cone outers and their interior turbine assemblies, I will also be continuing to skin the rest of the Viper and start installing all the ports for the reaction control system, (RCS). These mini thrusters are positioned around the spacecraft to provide attitude control in space. Aerodynamics there obviously does not apply but instead, Newtonian physics takes over. RCS can help by, "pointing" the craft in the desired direction while thrust rearward is applied. To reverse direction, thrust is cut, RCS flips/inverts the craft, then thrust is re-applied in the opposite direction to slow down, stop, or power into a new direction.


One of the reasons I really like this sci-fi ship, is because of this reasonably scientific application of space flight, instead of flying around in curves like you see in other shows. No more force-fields, beaming tech, lasers, or aliens. Bullets, bombs, missiles, nukes, armour plating and badass robots.

I need 20 of these, "Turkey feathers", for each engine exhaust nozzle. By the time I've added a frame, lining and internal details it's starting to get pretty heavy. The box-full you see below is enough for one nozzle, each feather comprising three shaped layers of plywood. To reduce weight, I've cut material out of the bottom layer with a hole saw. It's made a big difference.

I've moved the top engine nacelle out of the workshop and next to the Viper so that I can work on the rear exhaust and get my workshop back. I had to keep climbing under it to move around my workbenches.

Tonight I continued skinning the engines with recycled polystyrene produce boxes.

These photos with the roof coming off... Kind of put things in perspective and scale. I, for one, never realised how HUGE this thing is. Get me all worked up just seeing the photos and this little voice in my head keep saying, "Think we could build something that big? It would be really cool you know..."
Will you eventually skin this whole ship in fiber glas?

Welcome to the Taj Ma Baz. Now that the roof is off and the tarp is up, I was able to finish skinning the top of the Viper and put the top engine on. All the top and side surfaces are now skinned and glued, with a little skinning left on the bottom.

I also removed another saw-horse from under the Viper, leaving just one behind the rear undercarriage. I'll need a jack to lift the back end of the Viper to remove it.

Turning the twin 30mm cannons. Experimenting with pine, section at a time. I'm turning the details on the outside to diameter, then boring out the inside to slide onto a pipe and save weight. Worth a shot while the materials are free and available. This wood is from the old posts on my patio roof I just pulled down for renovations.

I'd like to think it would work doing the whole thing in pine as it is cheap and readily available. If I can't get the biggest diameter, then the rest of the weapon will likely be a hybrid of materials to get the job done.

It's coming out surprisingly smooth and in good condition considering how old it is and that the ends of the posts are rotten.

Engines off, correcting the height and angle of the starboard engine. Noticed a height difference in a front on photo and measured it to confirm. A difference of 10mm at the mounting point translates to 40mm down at the front. I can't live with that so let's roll the sleeves up and get it fixed!

Did I mention that the Viper is now entirely freestanding? No saw-horses. My friend Alex came over today and helped me jack the engine block up high enough to remove the last one. In taking the engines off to correct the alignment, I also took the opportunity to finish cutting and pre-fitting the last of the skin around the main engine block. Productive day!

Another midnight gone.

Unfortunately I don't have a wood lathe, but with a bit of creative thinking, I was able to make a tool rest for woodworking chisels and get things moving. The carriage on my lathe gets right in the way of large diameter stuff, so I pushed the tailstock back as far as it would go and cut my boxed timber in half.

After mitring the corners off the boxed timber with a circular saw, I mounted plywood plates to each end for the centres and turned it from octagon into cylinder and went from there.

Thanks mate. It's a pretty basic workshop. Standard stuff, drill press, vice, grinder and some hand and power tools. The lathe was a lucky pick up for $250 with tooling from a deceased estate. The son wanted someone to have the lathe that would put it to good use.

My workshop is small, cramped and very cluttered, especially when I'm making stuff. Hopefully in the coming years I'll upgrade to a 10mx10m shed. I have room on the property so I'm seriously looking into it, but the cost is holding me back for now.

Baz.
