Many thanks for that Tony and glad you enjoyed it!Blushing The Crocodile trailer was um, 'interesting' to say the least and to be perfectly honest, mine is a little over-scale compared to the original but even then, I can get four of them on my little finger nail! I think it does capture the 'feel' of the original though and in this scale that'll do!BigGrin
As you can see on my last Victory posting (ages ago now, the poor old girl!), details for ships is a perfect use for the resin casting method.
My favourite 'make' is the DWR Company's which advertise on ebay as their resins are non-toxic unlike the earlier formulas, so there's no problem with sanding it down etc. My DelPrado Victory kit came with a pair of cast metal boats designed to be hung from davits on the poop deck sides, I'll probably cast them in resin later - a lot less weight to suspend!Cool
Trailer coming soon!

Grateful thanks again to Alan and Phil!Blushing

Well, as Tony said above, the Crocodile’s trailer is definitely unique as far as the shape goes – as you can see from Photo 2 (from the Bovingdon Tank Museum), there’s hardly a right angle in the thing! Before that however, Photo 1 illustrates the Crocodile in action. Along with the Hawker Tempest, the Churchill Crocodile was hated by the Germans and the crew of a disabled Crocodile could often expect no mercy if captured. A little strange considering it was the Germans who first introduced weapons designed to burn men alive during the Great War! The Crocodile was an adapted Churchill tank, which retained its main turret gun and co-axial machine gun so could still function as a standard tank without the flamethrower. The fuel was a mixture of petrol with a thickening agent (basically an early form of Napalm) which ensured that the burning jet adhered to whatever it struck. The armoured trailer weighed six and a half tons and contained four hundred gallons of fuel when fully loaded. Armoured in this case was slightly optimistic, the trailer was bullet proof but anything larger could penetrate it and set it alight. To reduce the risk of the tank incinerating itself the trailer was towed with a jettisonable hitch so the tank could rid itself of the burning trailer and drive away. The early versions of the Crocodile used compressed air to spray the fuel with compressed air cylinders fitted at the rear of the trailer, by the time of D-Day however, compressed Nitrogen was employed instead. The fuel passed from the trailer through an armoured hose to the rear of the Churchill and then through the tank bottom to the flame projector which replaced the hull mounted machine gun on the left (driver on the right). The trailer, fully loaded and gassed would give the Crocodile approximately eighty bursts of fire of one second duration, using about four gallons on each burst. The range was quoted at one hundred and twenty yards but many reckoned it was closer to one hundred and fifty. The igniter was fitted within the flame projector and for taking out bunkers and fixed defences the tank could shoot out jets of fuel to drench the enemy position before igniting the whole lot with a final burst of fire. The Crocodile was offered to the Americans prior to D-Day but not wanting to have to train to use the British Churchill, they decided to work on a similar system to retro-fit to the M4 Sherman. This unfortunately was a complete flop and so throughout the Normandy campaign British Crocodiles found themselves attached to the American forces as and when their services were required. The Sherman variant was eventually made to work but mainly served in the Pacific theatre against the Japanese. (They came in two versions – one firing through the hull projector like the Crocodile and an improved type which fired the fuel down the main gun barrel.)
So the first job was to figure out how to get that unique (and fiddly) shape for the main body of the trailer. The solution was a scrap piece of 2mm thick plasticard, cut into a long strip of about 5cm length and 2mm square. Diagram 3 shows the stages in getting the body shape. The newly cut 2mm ‘plank’ was sanded down in stages, first the angle from top to sides and then the undercut slope below the flat side panel. When those looked about right I could then sand away the front portion to achieve the angled front end before then gluing on a much thinner length of styrene to make the ‘tow-bar’ section. In actual fact, because the tow bar is actually the ‘sprue’ as well, I didn’t reduce the front-most section as shown in the Diagram 4 but left it the same thickness and simply carefully sanded it down to shape after casting. The rest of the simplified details as shown in Diagram 4 were tiny pieces of styrene offcuts, shaped and then glued in position. The bars along the top sides and the rear locators (I didn’t add the front ones) were stretched sprue whilst the wheels were slices from styrene rod. When I added the wheels, I suddenly discovered that the ruddy thing was too short!Blushing (It was probably bang on scale as far as length was concerned but because the rest was a little overscale, overall it looked too squat and didn’t project far enough behind the wheel as shown in Photo 5. Fortunately, this mistake was much easier to correct than most. As I had sanded/carved the body shape from the ‘plank’ I could just add a drop of liquid poly to where I’d cut the trailer off, glue the rest of the plank back on and once it was set slice the body off a little further back!BigGrin The extended version is shown in Photo 6 with the elongated body attached with now enough room to add the rear tube holders. Photo 7 illustrates one of the first castings. These came out pretty well apart from the obvious air bubble in the wheel. Each casting had the same fault on either one or the other wheels so I added a pair of cut out channels to the rubber mould as I did with the balloon. Unfortunately, this time round it made no difference to the resin so I came up with the ultimately simple solution – if the resin won't fill the mould, fill it with something else! The wheels on the prototype were simple slices from a styrene rod so just cut a couple more of the same thickness and pop them into the rubber mould, pushing them down into the cavity before joining the two halves together for the pouring of the resin. The result is shown in Photo 8; a resin trailer bonded onto a pair of styrene wheels! I then just need to clean up the flash around the sides of the casting and slim down the forward end of the tow bar before gluing it to a Churchill with a channel filed out of the box on the hull rear to fit the tow bar into. The duo was glued together with a drop of superglue and placed in their final location on the beach to get the correct slope at the connection before the glue set. Then, as in Photo 9, the assembly received a couple coats of Vallejo Grey Primer before painting the Russian Green and weathering as shown in the Penny Shot in Photo 10. Finally, the completed tank and trailer were glued back down onto the beach with Deluxe Card Glue as seen in the final Photo 11.
So now I need to do a few more Barrage Balloons and a trailer or two to complete this section for later addition. For the next installment, while I get on with that, I’ll bring the current beach situation up to date with a series of ‘mini-dioramas’ which all add to the mayhem going on!
Until then, Stay safe and Happy Modelling to you All!

Robin.
