The rivetted water tank consists of the four water tank sides printed as one piece. The interior flanges and bolts have been included in the print.
A ledge has been printed inside the tank for a 3mm thick floor, layers of polystyrene or 3mm MDF would be suitable. Measure the underside of the tank for the floor, it should be 88.5mm x 88.5mm.
The White Natural Versatile Plastic (previously called White Strong and Flexible - WSF) material has a fine 'sandy' surface that needs to be sprayed with several coats of Auto Primer Filler or Auto Spray Putty and then rubbed back with about 1500 grit Wet and Dry paper to smooth the surface. It is up to the modeller to sand between coats or after several coats. Be careful not to sand the rivets.
This water tank is also available in Smooth Fine Detail Plastic (previously called Frosted Ultra Detail - FUD), click on the drop down arrow in the price/material area above.
The water tank pictured is sitting on a Laser Rail Bits timber stand kit. An alternative would be the Models 'N More version.
Or, a timber frame could be constructed using this plan.
Please note that the model pictured has only has one coat of primer on White Natural Versatile Plastic (previously called White Strong and Flexible - WSF) followed by the final colours to depict a perhaps more 'normally' finished model and not the multiple coats of primer and rubbing back to smooth the surface.
