jonhall Posted June 8, 2014 Share Posted June 8, 2014 Phase 1 of my cement tank build was to modify the cab of a base toys Leyland routeman to the smaller constructor cab, to do this the donor was dismantled and a thin slice was taken out just behind the door, the rear of the mudguard/wheelarch had to come off, and the wheelarch itself was slightly re-shaped. This interior was adjusted to suit, and then I felt the whole thing was too tall, so I adjusted the feet on the interior casting to reduce its ride hight (I may have gone too far). This left the front wheels too far forward, so I also moved the front axle to the rear position. The next steps for the cab will be to fill the grill in the front panel, and convert the double headlights to single. Jon Link to post Share on other sites More sharing options...
jonhall Posted June 8, 2014 Share Posted June 8, 2014 This is the type of tanker I want to model (photo courtesy of http://www.na3t.org ) The tank body I found in Germany was about 28.5mm in diameter, but intended for an articulated trailer, so unfortunately it narrows above where the 5th wheel would be, leaving not enough barrel to chop, nor the correct diameter cab-end dome Therefor what I've done is cut a section of 30mm diameter pipe to form the barrel, glue the coned discharge end to that, and at the cab end use the end from an airfix 35t class B tank that I had knocking about. The whole lot will need a fair bit of filling to get it all to blend. The other modifications to the chassis were to cut down the middle of each wheelarch at the back, I think it ought to be possible to join the two part-arches together to give a single arch over both wheels. I also docked the rear of the chassis, I haven't quite decided on where the rear of the tank would sit, the two photos below show a couple of different lengths. to be continued...

37114 Posted June 8, 2014 Share Posted June 8, 2014 Just picking up on a couple of points mentioned earlier: Re the Ergomatic cab, if modelling the blue circle lorries, they only used the later MK2 ergomatic cab, this is available from RTI. I started to modify an Oxford Diecast version but RTI beat me to it and so I chose the easy route. The Oxford Diecast chassis is a good starting point. Re the RTI body, it is suitable for the 6 wheeler, if anything it is a little short for the 8 wheeler. It is however a good overall shape and looks perfect on my Leyland Bison (see below), crucially the rear end shape is the correct offset conical shape. The walkway and ladder is wrong for a Blue Circle version but is correct for others such as Rugby, Castle Cement etc, however it is an easy scratch build. Below is my nearly finished Leyland Bison, the transfers used are Langley and allow a little too much "bleed through" so will probably be replaced with the RTI version. I will also post some pictures of my Scammell 8 wheel version soon although that is not up to the standard of the Leyland (Sorry about the fuzziness of the first picture, I can't seem to delete it) Link to post Share on other sites More sharing options...
37114 Posted June 8, 2014 Share Posted June 8, 2014 In answer to Jon Hall's post about where the body should sit on the rear chassis, I would say somewhere in the middle of the 2 positions shown in the photo. Link to post Share on other sites More sharing options...

From what I can tell the bumper/step/wheelarches remained the same through the range, it was only the cab part above that height that varied in width and length. The freighter/cruiser/constructor cabs were slightly narrower than the wheelarches etc. The blue circle cement picture you've posted looks like the cab should be shorter and narrower, like the one Jim S-W modified here: http://www.rmweb.co.uk/community/index.php?/topic/6104-jim-s-ws-road-vehicles-thread/?p=623031 Post #478. His was a tractor unit, but I believe the cabs were the same throughout the range. Link to post Share on other sites More sharing options...

His was a tractor unit, but I believe the cabs were the same throughout the range. Yes, the mudguard will need to be reinstated, but further back, if I'd kept the whole wheel arch it would have been OK, but because of where I took the cuts, it would have tried to pass through the middle of the wheel. Narrowing the cab is more work than I plan on doing, the 4 of these will be 3-4ft from the viewer, so can have the odd compromise here or there.

37114 Posted November 28, 2014 Share Posted November 28, 2014 Just dragging this thread up, here are a few pics of my tankers. I am tempted to do a flat next, I found a nice picture of a Dennis Dominant 4 wheeler which would look great. Link to post Share on other sites More sharing options...
river ewayon Posted December 31, 2015 Share Posted December 31, 2015 If anyone is into Cement lorries I must recommend The 2 Rugby Cement Transport books by Glen McBirnie. Lots of photos from angles that include that elusive detail that standard photos miss out. Thoroughly good reads and profits go to charity. Link to post Share on other sites More sharing options...
37114 Posted May 1, 2017 Share Posted May 1, 2017 I am building another one of the Blue Circle lorries now, the ultra rare (unique?) ERF B Series version as seen here: https://www.flickr.com/photos/35455701@N03/6042198422/in/photolist-acVR5S-8M896e-FEhrNH-TGRKDu-qsYGwA-bdXM7x-bXatMU-bKWfgn-otvnTW-FHcCLm-zBUmnb-zEgbEF-uK5Yvv-y2qma1 I was given the bits second hand hence have stuck with the ERF cab which came in the box rather than change it to a Scammell cab: Link to post Share on other sites More sharing options...
