Many people ask, "Is it a kit?" Why yes it is. But what does that really mean anyway? The "kit" consists of 300 pounds of the roughest cast-iron parts you have ever saw. These are called "castings". Actually, the quality of these castings is quite good. Even so, a large percentage of the weight of each piece will be machined away to get the part down to it's final size.

Also part of the "kit" is a pair of frames. These are the most expensive part of the project next to the boiler. These are .688" thick, and were cut from a sheet of steel using a water jet. Pretty cool. Then they were blanchard ground to precise thickness. You can always build your own frame out of 5/8th inch bar stock and weld it together, or start from a steel plate and cut it out yourself. But this is a laborious task and you may be faced with warpage problems. All in all, the water-jet cut frames end up being a bargain.

You also get quite a few "laser cut" parts made from plate steel, and
a good assortment of "lost wax" castings, cast in silicon bronze.
