sub frame

Here are some of the aluminum parts I’ll be using to assemble the sub frame. I’m still in the planning stages, but you can kind of see where it’s headed.

It’s mostly 1 inch square extrusion that will be notched at the intersections to make the whole thing 1” thick. Two large 0.060” ABS panels in the basic silhouette of the craft will be attached to the dorsal and ventral sides of the sub-frame and the wedges to to those.

With all the CAD work I’ve shown so far, I thought it’d be good to show something in the physical world.

The black block in the upper left is one of my ABS chunks that eventually will be the wedge of the saucer the has the radar dish on it, among other parts.

The little aluminum hex rod in the upper right is my mounting post. This will be part of the stand I’ll use to hold the model up while I work. It threads onto an old camera tripod.

pumpin’ CAD: part II

Here is the underside of the upper saucer dome. All the pin holes are used to register the parts onto the CNC machine. I’ll also use them to register onto the main decking material.

To prep the model for machining, it needs to be broken-up into smaller chunks. Well, my original plan was to make it all one part, but that ended-up being cost prohibitive. So smaller chunks it is.

first blood

A friend of mine just bought a new CNC mill. He eventually plans to offer machining services as part of his product development firm – but in the meantime, he wanted so practice. That’s where my little project comes in.

This was a practice cut. It’s the rough-in for one of the upper dome wedges. The parts are milled with consecutively smaller an smaller bit’s to capture more detail. This is pretty rough at 1/2” diameter. The interior of the parts are designed to be cut with a 1/4” cutter.

The Material is MDF – but the final pieces will be ABS.

scribbles

I liked these scribbles in my Moleskine. I’ve kept it on my desk in front of my keyboard as I’ve transcribed dimensions from photos to CAD. Solving the geometric equation that results in the right shape an proportion has been a lot of fun – for me at least.

master model

This is the base model in 3D. I’ve been using Solidworks to make the CAD data that will eventually be used for machining and for build reference.

Aside from a few unobtainable kit parts, this is as much detail as I’ll be putting into the surface model. All the armor plating and greeblies and other details will be done by hand – probably over the course of many years. Oh my!

I’ll show in a future post how this model has be “parted-out” for machining. It’ll be a mosaic of smaller chunks of ABS plastic.

Initially, I had looked at making all out of one large piece of ABS, but it would have cost a mortgage payment just to make the saucers – way out of my budget. Smaller pieces means I can be more efficient in cutting a dome out of a source material that starts off essentially square.

base model

My approach will, hopefully, be a bit unique. While I’ve done quite a bit of traditional fine scale modeling – most of my model-making experience come from the product design prototyping arena.

For this type of prototyping we use so pretty cool tolls that I hope to apply to my own Falcon build. I’ll employ some rapid prototyping, CNC machining, casting and probably some laser or ultrasonically cut part as well.

Of course, the ‘kit bashed’ portion of the model is where all the detail comes from. This aspect will be very traditional – except in instances where kit are no longer available, to too expensive to be had – like the Entex 935 RSR Porsche.

Having a somewhat digital workflow inevitably leads to a trail of digital assets. These assets, I’ll make avail able in some form here on the Falconer site.

The first of which is my 2D layout for the 32” Studio Scale model.

I’m using this as reference for placement of detail and overall proportion. It’s my translation of Helder’s documentation but it’s still largely interpretive – and in flux. But this is it as of the beginning of March. I’ll update it as my own model evolves.

The file can be opened into Adobe Illustrator and is dimensionally accurate, so you can grab measurements as needed.

resources

I started my Falcon project in early January, 2009. It took me about a month to start unearthing all the resources available online.

It seems typical of a falcon build that the falconer spends hours scaling dimensions off of grainy little photos or scans from old books (most of which are out of print).

I’m not sure it it was coincidence or fate, but about the time I decided to start my own build, Helder Santiago posted hundreds of high-resolution photos of his Master Replicas model. Most of Helder’s photos include ruler’s and calipers for good measure – quite literally.

Here are the links to his photos:
