Default Pursuit Ship - build along with Barry

Hello folks
I decided to drop out of lurk mode and contribute something.

Getting back into the modelling vibe lately I though it was time I tackled a studio scale scratch build. I'd always fancied trying it and being well aware of the "paralysis of analysis" (whereby you spend so much time researching you never actually start your project) I thought I'd just jump in and see how I got on.

Saying that - I have gathered whatever information I can (mostly from this very forum, thank you very much) and I spent the last few months buying the requisite kits for this build (and others)


starting with the Airfix Saturn V kit - which one to use?
I decided to stick with historical accuracy as much as possible. I was able to get hold of an original kit release as well as one of the later versions.




the above image shows 2 halves of the lunar module shroud.
the new release is on the left, the original on the right. They are pretty similar but the original is considerably narrower at the top.
you can see this in the next photo where I matched the two halves together as a comparison. Again the new version is on the left, the original on the right.




As I thought this would alter the profile of the nose, I stuck with the original.
Luckily I was able to eventually get 2 of these kits for less than 20 each from ebay.
This was going to become even more important when using the service module halves that act as detail underneath the wing cannons.

again - new version on the left, original kit part on the right.





just look at the outer size difference when viewed from above. Original kit part at the bottom





Luckily the stage 2 engine unit is the same on both kits so I started here.
I cut off the bayonet fixings from the interstage halves with a razor saw (what a brilliant tool) and glued them together. I then glued small strips of styrene inside the stage 2 engine unit to block the small holes as I did not want to see inside the model at all and joined it to the interstage.
with the addition of an ema ring (part VX-150) it begins to take shape.

You really need to use the original version, as early as possible...

Alawys like reading about Pursuit Ship builds, but never seen one with the comparision of the two kits - will be watching this with interest

I cut off the top part of the stage 2 saturn V parts and glued the 2 halves together. Rather than using another ema ring and having to cut it down, I cut out 3 identical circles from 20 thou styrene and glued them together. They measure 50mm accross. Once sanded I glued the new disc on top of the partial 2nd stage.







I then added the lunar module shroud parts plus the connecting ring, topped off with the small piece that connects to the Saturn V model base and the escape rocket cover.




I then started to add the ema column wedges (ref: KW12) and styrene triangles in pairs that appear between every 3 wedges

Great to see another Pursuit ship being built and it'll be interesting to follow this thread. I too got the new Airfix Saturn parts but ditched them in favour of the original parts and those photos show the difference well. Unfortunately even though I've now got quite a few parts to start building other things have got in the way plus with me I'd like to try and build mine using as much styrene kit parts as possible - even for the main body. I've been looking around to see if there's any donor kits that I can use. I got the Revell Vostok hoping that might be useable for the main body but it's too big.

Yours is coming along nicely though silverfox.

Rather ironically, I understand that Mat Irvine was instrumental in getting Airfix's Saturn V kit updated!

Great thread, I'm watching with interest.

I think that Mat thought the original parts would be included with the re-issue instead of being cut off the sprues for recycling

Bloody typical. I had to wait to get an older kit as most of them were expensive. In the end I managed to get one which wasn't complete yet had the PS parts.

If I was going to make another pursuit ship I would learn from my mistake and calculate how many column wedges and spacers it takes to cover the circumference of the nose cone. As it was I was left with a slightly larger gap than I anticipated. Consequently my ship has an arrangement of wedges in groups of three with one group of five. At least they are all evenly spaced and I will make my group of five the underside of the ship as though it was designed that way.

I then cut a circle of 30 thou styrene 800mm across and glued it to the base of the nose cone. It might have been better if this had been done first as it could have given a flat base to glue the trinagluar spacers and wedges against.

I next decided to add the slats around the top part of the nose.
each of the 16 slats were approx 60mm long with a 6mm base, tapering to a 3mm top.
I used the panel guidelines that were already on the LM shroud kit part to try and space them as evenly as possible.
With the addition of these slats it is really starting to get that federation ship look.





Taking a break from the nose I decided to make a start on the body.
Along with the wedges and rings I'd ordered a length of extruded tubing 82.6mm in diameter (ema code VT-325) It wasn't cheap at over 21.00 but then I knew this wasn't going to be a cheap project anyway. (I will provide a total parts cost at the end of the build to give you some idea of the overall cost.)





I cut a length of 210mm (the ema part is in lengths of 910mm) to act as the main body.
I think the originals then had a perspex tube of slightly larger diameter at the dront of the ship. I didn't have any so to make the front "collar" I wrapped the front of the ema tube in two sheets of 20 thou styere measuring 37mm deep and approx 261mm long.
I then added the saw tooth detailing at the front by wrapping a strip of evergreen strip styrene (ref: 134) 0.75 X 2.0mm around the front with shorter lengths of the same strip glued next to it.





I must stress that none of these measurements are necessarily correct to the originals. I've tried to make calculations as best I can from what resources there are but a lot of it is pure guesswork on my part. If you see anything seriously wrong or you know more accurate specifics, by all means jump in and let me know.





Here is the nose cone roughly placed on top of the body to give an idea of the dimensions so far.

Good news...
I wouldn't worry in regards of specific details as each of the 3 built by Martin Bower were detailed slightly differently as he was using kits he had to hand and didn't quite have enough to detail each one identically.
As long as you have an Mpc/ertl/Airfix eagle transporter, Aifix Skyray -2 required - and Beaufighter (old tooling). That should be all you really need to make a superb replica. Ok so you also need some 1/24th harrier parts, but these can easily be scratch built.
The fourth Pursuit ship was built in house and uses a few more parts being converted from ServelansCommand ship from Season 2.

Oh and the originals were made using EMA tubing. Perspex was only used for the Wings and stabilisers.

Thanks for the replies. I have an Eagle, a couple of Sky rays, a German E-Boat and a 1/24 Harrier already. The Beaufighter is a new one on me though. Details for the underside of the nose cone perhaps?

So far it looks spot on silver and it's giving me inspiration to get on with mine. I didn't know about the Beaufighter either.

I take it you used cut plasticard for the nose slats?

Is it the 1/72 scale Airfix Beaufighter ? or the 1/48 scale ?

Hi - I'm a newbie to the forum but a genuine old school fossil when it comes to Blakes 7 although I must confess that I have learned more about the series in the last year from various forums and specialists like all your good selves. The show was an immediate weekly highlight for me and the liberator has always been my most favourite ship.

This build looks amazing and I shall enjoy watching it unfold throughout the assembly.

I'll have a Titan find Libby at Telford this weekend if anyone is interested - it's presently on britmodeller in the wip but is not up to date as I am on a tight schedule with the build now

Good luck with the pursuit craft

John

Silver one thing I've noticed. You say you cut a round base for the nose cone and it's 800mm across. Shouldn't that be more like 80mm?

Yes - I used 20 thou (0.50mm) styrene, otherwise known as plasticard. I buy it A4 sized in batches of 10 or 20 sheets at a time.

Hah! It was a slip of the finger. You are of course correct it should have read 80mm across. For the record that may end up being a tad small. It doesn't quite cover the diameter of the open front end of the main body. I think I'm going to have to glue a slightly larger diameter circle behind it or cover the end of the main body so that it is blanked off. Photos etc when I get to that bit...

Thought that would be the case and it's easy to tap in an extra 0. It's really handy to have your measurements as even though the other Pursuit ship thread was really helpful it's great to see yours progressing. Especially with someone like me who's not very good with measurements.
