Sizes

Our models are designed to be built from many layers of 1/8 inch thick plywood. We refer to models made from this thickness as “Single” sized engines. You can order most of our models cut out of 1/4″ thick plywood as well. All dimensions are twice as large. These are referred to as “Double” sized engines, are are intended for public display. A select few of our models are also available in “Triple” size. These are cut three times as large out of 3/8″ plywood. In general, single sized engines kits are kept in stock and can be shipped as soon as you order them.

Before you Order a Double or Triple Kit:

Double and triple sized kits are cut after they are ordered. As a general guideline, a double sized kit requires a two week lead time, and a triple sized kit requires a month lead time. These are estimates only, and will depend on the current production schedule. If this time frame could be a problem for you, it is best to contact us before ordering a double or triple sized kit to see how long production will take.

We have developed our own proprietary system to minimize laser scorching on our single sized kits. Unfortunately, this system does not work for our double or triple sized kits. Additionally, we must run our laser slower and at higher power settings for the larger models. Expect to see significantly more scorching and smoke deposits on our parts as the thickness increases.

It is also important to note that all of our kits ship with the same instructions. If you are going to assemble a double or a triple kit, be prepared to double or triple any dimensions listed in the instructions.
