Rear jack mounts

For some reason this was one part of the build that I wasn't looking forward to - but it proved to be very satisfying.

The HL jack is simply attached to the rear hull using two plastic pegs - so there are no visible mounts at all. It's also hollow underneath. The Tamiya jack, not surprisingly, is superior with good detail on both sides, but the brackets are simply 'U'-shaped pieces of metal which screw into the hull - hardly much better.

On the real Tiger the way in which the jack was held in place was actually a little more complicated than I first thought. Something I had overlooked was the fact that the weight of the jack actually rests on two fixed brackets beneath it. The function of the more prominent three-part hinged brackets was to clamp the tool against the back of the tank - not to bear its weight. These can both be seen clearly in the shot of the Bovington Tiger above. This arrangement changed very slightly when the 15-ton jack fitted to mid-production Tigers was up-graded for the steel-wheeled variant to the 20-ton one (the lower brackets moved slightly).

The Tiger jack actually rested on two brackets with slightly up-turned ends.jpg (29.94 KiB) Viewed 8761 times

So how did I make the jack mounts? Actually it's SovereignZuul http://www.rctankwarfare.co.uk/forums/v ... 22&t=10204 I have to thank for a really useful tip when he was doing his jack mounts: using square plastic tube. The best size is 1/8" (otherwise described as 0.125" or 3.2mm x 3.2mm). Mine is made by Evergreen.

This has several advantages when it comes to building many of the mounts and brackets for tools on the Tiger 1. The original parts were often made from cast or bent thin metal - again see the Bovington Tiger pictured above - so that parts of them are quite three-dimensional.

Of course, because the tubing is made of plastic it is also much easier to carve or shape than metal. Also the square cross-section means that even when you cut it down to the depth of one side it has a rigidity that a simple flat strip of plastic card would never have.

Back to the brackets...

First I worked out where they should be attached to the rear plate and cut out a strip of zimmerit before adding cut-down plastic tubing to the hull. Here you can see the advantages of this square tubing - by leaving part of the sides intact I created the hinge mounts for the next section. It was only after I then presented the actual (Tamiya) jack that I realized that I had made a schoolboy error by lining up the right edge of the tool to the side of the rear plate rather than the rear corner of the side plate. So I had to shift them a little...

Next I shaped the lower and rear parts of the three-part brackets from the same square tubing.

Like the real ones they have to be different shapes and lengths because they fit around different parts of the actual jack. Unlike Sov's build I didn't plan to make these working brackets, but in order to look right it helps to make them as if they were going to be moveable.

The next stage was to wrap these pieces around the Tamiya jack itself, ensuring they lined up with the pieces I had already attached to the hull. For added strength I also cheated slightly by adding metal pegs to the rear of the lower jack brackets and drilling holes into the rear plate to take them.

This shows the Tamiya jack from beneath - this detail is missing from the HL part.jpg (27.09 KiB) Viewed 8761 times

Jack brackets continued...

Two-thirds of the jack clamps have been installed and the metal pegs are in place to secure it to the hull.jpg (36.04 KiB) Viewed 8756 times

Once I had the lower and rear sections of the brackets glued to the jack itself I could mount it on the rear hull.

I was going to make the upper brackets from brass strip, but since the whole assembly already felt rock-solid I thought this unnecessary. So more plastic tube was cut to shape so that it fitted to make the missing side of the square. Into each of these a notch was cut where on the real thing a screw thread and butterfly nut held the brackets together.

Finally I added the fixed brackets underneath the jack. Because these have slightly upturned ends I made them from brass strip with triangular fillets from plastic card.

The final touch (almost) was to add the butterfly/wing nuts and the jack handle itself. I will discuss the butterfly nuts further below, but these are by Schumo: beautifully cast in metal complete with threaded screws. I thought I really had to use metal pieces here because they sit on such an exposed part of the tank - especially during any careless reversing!

All that's left is the small clamp which holds the handle against the hull. That's going to have to wait because I have some far more challenging clamps to build first - the ones which hold the towing cables in place...

Very nice fella!

[SovereignZuul]

Amazing on the jack mount! Superb! I'm jealous, hehe.

Where do you get Schumo parts? Their website is down (http://www.schumo-kits.com/) and I can't find anything with google strangely enough.
I'd love to get some wingnuts for my cleaning rod/tow cable bracket.

[tanks_for_the_memory]

Thanks gents!

Schumo butterfly / wingnuts are available as I type - in the UK at least - from Tankzone or Welshdragon. Tankzone are the cheapest - free postage - sorry Steve! Still £4.50 for a mere 6 mind...

Well, on with the show...

Towing cables and brackets

Front towing cable brackets with Taigen cables installed - soon to be replaced by Schumo.jpg (36.03 KiB) Viewed 8683 times

The large towing cables are a distinctive part of the Tiger’s tool stowage. They had to be long and very strong so that between them they could take the weight of the tank (or another if, as they often did, they were towing a crippled Tiger).

The HL cables are more or less a straight copy of the Tamiya ones. Both come moulded as one piece complete with the front and middle brackets – the latter incorporating the barrel cleaning rods. Like the moulded-on tools they scrub up quite well with a decent paint job. However, they are a little over-thick, lacking in detail and, for some reason, don’t even line up with the attachment points for the middle brackets moulded into the hull roof. They also lack the rear clamps (two each side) which are located on the engine deck – and these are missing from the Tamiya versions as well.

So what are the options? Several manufacturers make tow cables, either moulded in one piece, ready-made with real twisted wire or as a kit with wire, separate eyelets and sleeves. However, none of these come with the clamps which actually hold them to the top deck. There is, of course, the Aber option – but I believe these are only available as part of a complete up-grade kit (expensive) and – like most Aber photoetch – not easy to make up.

My first choice for the towing cables themselves was to go for the Taigen ready-mades and it is these you will see in the first photos. However, I soon discovered that they also have issues: first, they are slightly too thick, second, they have a bit too much 'spring' - making them hard to keep in place. A third problem, which was probably my own fault, was that they were too long. In fact it turns out that I must have bought the Tiger II cables by mistake - they are 70cms long, whereas the Tiger 1 ones should be 60. So I have purchased the Schumo set instead, which also are a little thinner and, to my eye, more to scale. More of these later...

As I soon realized, however, the cables were the least of my worries: once you do away with the all-in-one plastic cables you also do away with the brackets which attach them to the hull roof. Making these brackets seemed a daunting enough task in itself - until I also faced up to the fact that the cables would have to be detachable just like the real thing. After all, the real Tiger was painted and camouflaged without them in place. They also had to be strong enough to keep the heavy cable clamped in place on the deck - so that is what I was going to have to do!

Front brackets finished off with the Schumo butterfly nuts - all they need is a little bedding in with Milliput weld beads.jpg (25.22 KiB) Viewed 8683 times

The four front brackets are the trickiest. Essentially they each consist of three parts: two metal pillars, one with a hinge, the other a butterfly nut on a screw and between them a hinged bar which keeps the eyelet clamped to the deck.

The forward part of each bracket with dress pins inserted.jpg (32.56 KiB) Viewed 8683 times

Once again the square section plastic tube - the same type I had used for the jack brackets - came to my rescue. First the four pieces for the forward end of the bracket were cut to the required height. One side was cut away - the side facing aft which will not be seen once the cables are installed - and the top sanded to a rounded profile. I then drilled a hole for the hinge and inserted a dress-making pin. These pins are excellent - cheap, uniform and strong. They are going to come in very useful! They should be found in any haberdashery store - for those of us in the UK they are cheaply available at Wilkinsons.

The rear part of each bracket was cut from the same square plastic tube.jpg (60.44 KiB) Viewed 8683 times

The rear part of each bracket was trimmed from the same square tube - this time laying flat. Here I cheated a little because on the real vehicle this part of the bracket has a threaded bolt mounted on a swivel mount to allow it to be raised to meet the butterfly nut - I planned simply to drill a hole into the hull to take the thread of the Schumo part.

For the clamp itself the end of a brass strip was filed narrower, then bent around a drill bit.jpg (68.11 KiB) Viewed 8683 times

The end once bent should look a bit like this.jpg (31.04 KiB) Viewed 8666 times

The moveable part of the bracket was made from brass strip. One end was filed so that it fitted between the top of the sides of the forward bracket, then bent so that it would tuck under the dress pin I had already inserted. It took a little trial and error, but eventually I arrived at a working hinge. Note that, just like the real thing, this part is slightly bent to allow for the fact that the forward part of the hinge is higher than the rear.

Positioning everything on the top of the hull was another stress. Scale drawings help, of course, but I also had to ensure that the brackets did not foul the opening hatches. My initial attempts proved to be way out...

Small tacks were inserted into holes drilled in the hull roof to provide an achor for the plastic brackets.jpg (21.57 KiB) Viewed 8683 times

Also, because I was worried about the strength of the brackets versus the Taigen cables, I glued them to tacks inserted into holes drilled into the hull top. However, after they had been fixed into place I wondered if this was necessary, especially once I had also inserted the Schumo butterfly nuts.

Dear Gentleman Tim..... I think your build is moving into the art category .... you and Derek just keep raising the bar ! . Pure class Ace

Here are some pictures showing the real cable brackets and clamps - they are either my photos from the surviving Tigers at Vimoutiers and Saumur or they come from the Modeler's Guide to the Tiger book.

In the first photo (from the Vimoutiers Tiger) the upper clamp bracket appears to be upside down. Sloppy workmanship?!
[Actually I shouldn't joke - by this stage of the war a lot of these tanks were being built using slave labour...]

On with the cable clamps...

The rear brackets are the simplest.

For the rear cable clamps I started by filing 4 U-shaped depressions in a piece of thick plastic square rod.jpg (35.25 KiB) Viewed 8495 times

Next I drilled holes for each end of the clamps.jpg (31.39 KiB) Viewed 8495 times

Dress making pins were then inserted into one end of each clamp.jpg (70.23 KiB) Viewed 8495 times

Four large parcel staples were then cut to length, drilled and held in place with the pins.jpg (13.95 KiB) Viewed 8495 times

Now separated, the pins were then cut shorter and each staple segment had a notch cut into one end.jpg (33.29 KiB) Viewed 8491 times

One side of each clamp was then cut away for the folding butterfly screws would be fitted.jpg (35.16 KiB) Viewed 8495 times

In photos of the real thing you often see the rear deck hatch hooks over the tow ropes like this.jpg (36.43 KiB) Viewed 8495 times

Another view.jpg (32.94 KiB) Viewed 8495 times

Because the Taigen tow ropes are a bit on the thick side the clamps sit a little too high - so I am expecting the Schumo ropes to look better (once I get round to making them up!)

Also, like all of these fittings to the Tiger, they will need to be bedded in with Milliput weld beads.
