Radial Engine
The radial engine is a reciprocating type internal combustion engine 
configuration in which the cylinders "radiate" outward from a central crankcase 
like the spokes of a wheel. It resembles a stylized star when viewed from the 
front, and is called a "star engine" in some languages. The radial configuration 
was very commonly used for aircraft engines before gas turbine engines became 
Since the axes of the cylinders are coplanar, the connecting rods cannot all be 
directly attached to the crankshaft unless mechanically complex forked connecting 
rods are used, none of which have been successful. Instead, the pistons are 
connected to the crankshaft with a master-and-articulating-rod assembly. One 
piston, the uppermost one in the animation, has a master rod with a direct 
attachment to the crankshaft. The remaining pistons pin their connecting rods' 
attachments to rings around the edge of the master rod. Extra "rows" of radial 
cylinders can be added in order to increase the capacity of the engine without 
adding to its diameter.
Most radial engines use overhead poppet valves driven by pushrods and lifters on 
a cam plate which is concentric with the crankshaft, with a few smaller radials, 
like the Kinner B-5 and Russian Shvetsov M-11, using individual camshafts within 
the crankcase for each cylinder. A few engines use sleeve valves such as the 14-
cylinder Bristol Hercules and the 18-cylinder Bristol Centaurus, which are 
quieter and smoother running but require much tighter manufacturing tolerances.

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= 389
W = 389
H = 170
Approximate Size at 1/8 inch
L = 15.3
W = 15.3
H = 6.7
Approximate Size of Largest Part
12.4 X 12.4 inches
315 X 315 mm
Approximate Part Number: 158
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.
