Stirling Engine
 
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas the working fluid at different temperatures, such that there is a net conversion of heat energy to mechanical work. More specifically, the Stirling engine is a closed-cycle regenerative heat engine with a permanently gaseous working fluid. Closed-cycle, in this context, means a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. The inclusion of a regenerator differentiates the Stirling engine from other closed cycle hot air engines.
Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.
Stirling engines have a high efficiency compared to steam engines,being able to reach 50% efficiency. They are also capable of quiet operation and can use almost any heat source. The heat energy source is generated external to the Stirling engine rather than by internal combustion as with the Otto cycle or Diesel cycle engines. Because the Stirling engine is compatible with alternative and renewable energy sources it could become increasingly significant as the price of conventional fuels rises, and also in light of concerns such as depletion of oil supplies and climate change. This type of engine is currently generating interest as the core component of micro combined heat and power units, in which it is more efficient and safer than a comparable steam engine. However, it has a low power-to-weight ratio rendering it more suitable for use in static installations where space and weight are not at a premium.

Hello and thanks for shopping with Makecnc!
These 3d puzzles are a downloadable product that have been made ready to cut on any CNC router or CNC laser machine.
They are supplied as ready-to-cut DXF vector files for CNC routers and EPS for CNC lasers machines.

Patterns may be scaled to the size you require for your material thickness using our Scale Calculator

CNC Routers Users ! Please See our Tutorial for information on dealing with Inside Corners and Dogbone Fillets

Each Zip File Includes:

2 or 4 CDR Files - Sizes you receive Depend on individual Product - usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions (Corel Draw Format for Laser)
 
2 or 4 DXF's - Sizes you receive Depend on individual Product -  usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions (For Most CAD Programs)
 
2 or 4 SVG - Sizes you receive Depend on individual Product - usually in 1-8 and 3 mm and/or 1-4 and 6 mm Versions  (Opens in Many CAD & Drawing Programs) 

Printable PDF Pattern  (For Scroll Saw Use)

1 X  Clear and Concise Color Assembly Manual.

1 X  Number Guide DXF (Also called Coded DXF - NOT in all Products - Only in Certain Products)

1 x Readme File and Copyright Information

1 X Product Notes -  Letting you know an Approximate Height, Length and Width of your finished product and giving the Approximate Size of the Largest Part.  These Approximations are given in Imperial and Metric. Remember, These are Approximate Sizes. 

Approximate Size at 3mm
L= 305
W = 137
H = 124
 
 
Approximate Size at 1/8 inch
L = 12
W = 5.4
H = 4.9
 
Approximate Size of Largest Part
12 X 5.4 inches
305 X 137 mm
 
Approximate Part Number: 125
 
NOTE: Our 3D Puzzles can be built in different thicknesses.

Example: 1/8" uses 1/8" Plywood...1/4" uses 1/4" Plywood, etc.
As a rule, although the slots are set to fit the same sized tool, most
people will use a smaller bit size when cutting.

All the hard work is done!

Makecnc is excited to bring to the CNC hobbyist a new and ever-expanding library of art and projects made ready-to-cut on your CNC machine!

You can either sell the cut out projects as your own product or assemble them for your own enjoyment and to give as gifts to your family and friends.
