Curved or 'Splasher' plates

The last thing we want to do is to supply a plate that doesn't fit perfectly in the chosen location, but we're only as good as the dimensions given.

A curved plate is very unlikely to have the correct shape unless precise measurements are taken from the actual Loco, Traction Engine or other application. There are too many variables to depend on simple scaling to trust that plates will fit.

Working direct from drawings can also create problems - the people who drew up established designs took a lot of liberties with true scale, and if the plates are scaled down from full-sized works drawings or the prototype engine, errors can still creep in. The only way to ensure success is to measure the actual model.

After the actual top and bottom radii have been determined, things are drastically improved by our system. With given radii, we can create an actual size drawing and then E mail it to you for actual size printing and trial on the loco at your end. This can save a lot of wasted time and money on both sides.


Curved or Splasher plates can only be made using top and bottom radii taken from the actual model.

The Red line in the picture represents the radius to the top edge of the plate, and the Yellow Line is there to represent the radius to the bottom edge of the plate. All you have to do is to decide how much space you want to leave above and below the plate.

The same principle applies to splasher plates - measure the top and bottom plate radii from the centre of the wheel and then decide how much space you want to leave above and below the plate. When the has been done, you'll have the top and bottom radii of your proposed spasher plate.

In either case, there is no need to try and work out the arc span of the plate, as we arrive at that by allowing your chosen lettering to dictate what it should be. Using both radii will also produce the difference between the two, giving the height or depth of the plate.

Curved plates are extremely wasteful of material. This 4" wide plate actually required a blank 8.5" wide to make it.

They also require a lot more initial drawing time. As a result, curved plates are more expensive than a rectangular plate.
