Converting Emhar Mark IV to Mark V
Permalink   

Because nobody makes a Mark V, except in card, I have been discussing and considering converting either the Airfix or the Emhar kits. Coverting Cromwell's Mark V*, in the way Peter Kempf has done, was briefly considered, but discarded because it is an expensive model (the rear cabs are different on a V* versus a V, and there are no unditching rails with the Cromwell model, so it would still need quite some work).

Converting the Airfix kit would require building or buying some sponsons and the final model would be 1/76.

Converting Emhar's male Mark IV would require building or buying some sponsons. And a pair of sponsons from Matador costs as much as a whole tank kit. They are very nice. But not exactly cheap.

So the idea of converting Emhar's female Mark IV was suggested as being the 'best of a bad bunch'.

So I have started to make a list of what would need to be changed, to convert Emhar's 1/72 Tank Mark IV female to a 1/72 Tank Mark V female. As I find the time I will add side-by-side comparison photos of the various features. Hopefully, or maybe, it will build up into an article that modellers can use (at least while we are waiting for HaT, Emhar or Airfix to make a Mark V kit).

It is written in word 2003 because most people have that. Needless to say, suggestions are invited and very much appreciated.

EDIT: The latest version is attached to a later posting, below.

Thanks for the list, probably won't attempt it by myself as i'm rubbish at conversions! I'm surprised Matador haven't bothered with a conversion to be honest

I have asked Matador why they don't make a Mark V conversion. And they gave this very good answer; so much needs changing that a conversion kit would be almost a complete tank kit by itself.

I'm surprised Emhar haven't scaled down their 1/35th kit!

Just a few more conversion points for your list.

You will need to fill and rescribe the left and right side panels just behind the sponsons. The panel line is closer to the sponsons on the Mk V. Pictures attached to show the differences.

The sponsons are the same on Mk V's and Mk IV's but the MG mounting varies. You can just use Emhar's sponsons as supplied but for making a particular tank you need to check photos. I've attached drawings (not to scale) showing the main variations. Also Emhar's sponsons need rerivetting along the top edge as this was rivetted in two and a half lines, not a single line.

Grousers were used on some Mk V's but these were of the pattern used on Whippets. Picture attached.

The towing point just ahead of the cab was different on the Mk V. Oddly enough, Emhar have given you an ideal picture of this on their box artwork even though it is incorrect for the Mk IV. Use that as a reference.

The mud deflectors (if fitted) were only fitted to the port (commanders) side of the tank. Patterns varied and NTS drawings are attached showing the main types. Use photos to determine which, if any, to use.

Two more conversion items:

The mud chutes were on the outside, not between the rear horns as on the Mk IV. Emhar didn't mold either type so at least you don't have to fill in the ones between the horns as you would have to on the Airfix version.

The silencer was fitted to the right of the roof, not the left side as on the earlier Mk's.

Mark, thank you. I'm glad you picked up on this thread. Can I put your drawings and photos into 'the article'? And quite a while ago you posted a gif comparing the cab fronts that I'd like to use as well, with your permission of course, if I may.

No problem. I can't find the original on my computer so if you've got a copy or know where one is, feel free to use that. If not, I can reassemble it from my other drawings.

 Rob, if you want a brain-dead easy conversion, I posted an article that Peter K has put on the main website for converting the Emhar Mk IV female to a Mk III. Very little to be added.

Which reminds me... I must finish that tank and base some day...

I've done a little bit more work to the 'article', incorporating some of Mark's comments and pictures.

Here is the latest version:

This is an excellent resource thank you, are the port and starboard sides symmetrical on the MKV?

I'm going to go out on a limb and say, I am strongly convinced (but easily persuaded otherwise!) that the left and right sides of a Tank Mark V female were symmetrical, ie mirror images. If they are not, the difference is possibly so small that it does not show in 1/72.

I know that male tanks were not symmetrical, or rather, the male sponsons are not symmetrical, because of some sighting equipment that had to be on one particular side of the 6-pounder.

And, obviously, composites were very far from symmetrical. (I don't like using the word 'hermaphrodite' as it plays havoc with google and yahoo search filters!)

 Port and starboard of the tank body, yes, except for the mud deflectors. These were only attached to the port side when they were fitted.

could you/would you think about doing a drawing of the back of the mk iv and mk v like the one of the front view of the cabs?

fantastic work, thank you

Thank you revans.

The drawings of the front of the cabs are not mine; they are Mark Hansen's. I don't have such talent! That's why I'm glad he's joined in and given his permission to use his photos and drawings.

If you are looking for a plan you might try some of the Russian forums, although I have not seen any good plans of the Mark IV. (But then, you have the Emhar female Mark IV, right? So no need for a Mark IV plan, eh!). George Bradford has produced a spiffing plan of the Mark V. It can be seen in the latest Service Publication, 'Great War Tanks in Canadian Service' by Michael McNorgan. However, the plan is copyrighted to George Bradford.

 Talent?? Are you sure you're talking about my drawings?wink  I'll see what I can do for the rear of all the heavies. It may take a while though...

The plan is off in a few details. It has mud deflectors on both sides, the semaphore ahead of the rear cupola on the plan drawing, the rear plate is a bit simplified (no rear door and no fuel tank details), and the semaphore is shown offset to port on both the rear and front end elevations.

Yes, George's plan is 'off' in a few places, probably because he was trying to simplify it. But it is very 'user friendly' when combined with photographic evidence. And he's a really nice guy!

Some other plans of the Mark V are a bit too complicated. There doesn't seem to be a 'middle ground' with plans.

Changing the subject, does anyone have any good photos that show the roof very clearly, of either Mark IV or Mark V? I have some, but more would be better!

Here is the latest version. I think I might call it a day with this, unless anyone makes a valid comment. What do you think?



PS. Can the forum moderator please remove the attached file on the previous posting, as it is now out of date and could cause confusion.

I trust it's OK to post this opus of yours on the site. Or?

Great conversion program, thank you for sharing.

All the very best.

There are a number of manufacturer's contemplating a Mark V. One of the mastermakers of Matador informed me that they'd rather do a full kit instead of a conversion, but he hasn't started on it yet. I'd say that if you want a Mark V, you might as well start working on Phil's conversion.

Michel.
