Re: Source for large cylinders with round ends?

May also want to think outside of the box. Plastic pipe from a hardware store, comes in standard dimensions, albeit english ones. For example, I recently bought a very expensive resin kit, and the engine supports exactly fit some plastic pipe I bought at said hardware store, which gives me both a cl...

Re: accurate At-At blue prints

(IMHO) I believe there aren't any art department blueprints of the AT-AT. I just went through the Rinzler Star Wars: Blueprints book and there are no blueprints of the AT-AT. A bunch for the chicken walker, but only photographs for the AT-AT. My suspicion is that because of the AT-AT stop motion FX ...

Re: Technique for drawing bulkheads from drawings?

Just elaborating on what Naoto is saying. I've seen many drawings on the internet that are not consistent across views, i.e. the front view has drawn features that should correspond to the same feature in the side view, but do not match. For example, there is a 2 view drawing of the AT-TE (clone wal...

Re: Source for small photoetched stars?

I have had good luck laminating sheet styrene into rods with a particular cross section. For a star, you'll also need to sand your build up to get the star's sharp corners, but should not be too hard. Then cut thin slices to get the pieces you want. Getting them all the same thickness requires eithe...

Without sounding like a cranky naysayer, but an egg shape one foot long, you're at the very limits of high resolution model making reproduction.
