Well I've finally managed to get my sticky mitts on Dragon's 1/72 Saturn V kit - I've done a little writeup/review of the kit here http://www.martins-models.co.uk/Sales/7 ... aturnv.htm
As mentioned in the review, the kit isn't particularly accurate in many respects ( did I mention that understatement is a skill of mine ? ), so I plan on addressing its shortcomings as I build it.
The first thing I did was to make a Lox tank dome for the S-IC first stage. For some reason the kit doesn't include one, just one with a hole in it for the stand rod that fits further down the stage ( by comparison the S-II stage includes both a tank dome AND the transit support structure used when the stage was being transported or lifted - a mistake Monogram made with their 1/144 one ). I used the S-II dome as the basis, adding various details such as pressure switches and pipe flanges.

First resin Lox dome, fresh out of the mould

Next I turned my attention to the S-1C forward skirt. The kit one has 108 stringers, half the number of the original, so a couple of hours ( and a load of Evergreen 1.0x0.5mm strip ) later it now has the correct number of stringers. Then I made the forward umbilical panel and access hatch, as well as the two Lox vents.
Image

ODOP antenna panel in place, and interior structure done. I couldn't find any definitive drawings of the interior, but one NASA document states that the skirt was made up of 12 external panels, so I've gone for 12 vertical stiffeners between the three rings. Next step will be adding electronics boxes, wiring & piping - again an area where there isn't any definitive info, and I've yet to find a good photograph of this area that isn't obscured by the lifting/support frame, so it's going to have to be the old guesstimate method again.
Image

And S-1C forward skirt just about finished ( need to clean up the areas where the system tunnels go ), with exterior antennae, interior details, and the 48 tiny vent holes :)

Just waiting for a delivery of silicone to make a mould and resin copies will be available
Now on to the system tunnels - kit ones are the wrong shape and lack the surface details of the real ones

System tunnels - the kit ones are too high, too long, and don't have the ribs that appear on the real ones, so. The real ones are made up of a number of separate sections ( presumably each could be removed separately for access ) - fortunately there are only 4 different sized parts so I've made one of each size which I'll replicate in resin ( 2 ends, 2 long sections, 1 medium section, 28 short sections per tunnel ), then assemble the resin ones into the final part ( I'll probably cast each tunnel in 3 parts ). Below are the parts - just waiting for silicone to arrive now

The kit's on my wishlist, so I'll be watching your (always impressive) work with interest.

S-IC Intertank access hatch and Lox fill/drain umbilical. The part is designed to sit over the kit stringers
Image
So now I've sorted the top half of the S-IC stage, time to look at the bottom half - a mammoth task. The engines are the wrong diameter ( way too small ) and lack the insulation batting of the flight engines, the aft heatshield has too many panel lines engraved on it, the engine fairings are the wrong size and shape, there are no hold-down posts, and there are no umbilicals......
Quite a lot to do then :(

It'll be worth it once you're finished, I'm sure.

Looking really impressive. Can't wait to see how she turns out.

I've been wanting to have a go at one of these since I was a kid. How tall is it. 1:72nd must be hugh!

According to NASA, the Saturn V/Apollo combo was 363ft tall, which scales out to 5ft and half an inch.
