"A boy's will is the wind's will,
And the thoughts of youth are long, long thoughts."

from the poem, "My Lost Youth," Henry Wadsworth Longfellow's
thoughts about his boyhood in Portland, Maine

Dreams of steamboats are those of men who have always been kids
Every once in a while a dream is caught and a flame burns brightly

the continuing saga of the steamboat "A Boy's Will"

Will Weidner, Equinox's creator, has graciously contributed a simple to use dynamic spreadsheet for designing D or piston valves. Feel free to download and use the attached file. Simply click here to download the file. It can then be viewed in MS-Excel, OpenOffice or any software that can handle an .xls file. Once the file is opened just change the input values to determine how the changes you've made influence the valve's performance. It's great for new engine designs or tweaking your current engine for peak performance. Here's Will's description of its use:

“The Spreadsheet “VALVGR2.xls” is a useful tool for designing a slide valve for eccentrically driven valve gears. A lot of engine plans may have a slide or piston valve designed by the seat of the pants, but when the analysis is done, it can be seen that a lot of improvement can be made. A huge increase in economy can be the result. When the valve on an existing engine is optimized, it seems like the engine driven feed pump suddenly has an increase in output. Of course lower steam consumption is the reason for this. It will also seem like the boilers’ appetite for wood is greatly diminished.

Using this spreadsheet allows you to make changes to valve parameters (valve travel, advance angle, admission and exhaust lap) and immediately see the effect on valve events. It allows you to do is adjust the admission lap and exhaust lap separately for both the forward stroke (top of piston) and return stroke (underside of piston). This allows you to compensate for the non-uniform motion of the valve vs. piston position due to the connecting rod angularity error. Uniform valve events for forward and return strokes are the result. That’s why there are pairs of input numbers for admission and exhaust lap. Try putting the same numbers in for each to see the angularity effect.

This spreadsheet has limited use for linked-in Stephenson motion because it requires you to know the eccentric throw and advance angle. It is very useful for Stephenson in full gear, or slip eccentric valves. Stephenson gear that is linked-in has a “virtual” throw and advance angle, but they are hard to determine analytically or graphically. They can be determined on the engine by linking in the gear to the desired position. Then measure the valve travel with indicator or calipers while turning the engine over. Note the crank pin angular position from TDC or BDC when the valve is at its extreme position. Subtracting this angle from 90 will give the advance angle.”



The Lee's Mills Annual Steamboat Meet

is held in September each year

FROM THE SECOND SATURDAY THROUGH THE THIRD SUNDAY

a total of 9 days

Moultonboro, NH

(sometimes spelled Moultonborough. After all, this is New Hampshire!)

Follow signs to the Loon Center and continue about 2000 feet to docks

Show up during this session and ride some great steamboats FREE!

The Lees Mill Meet is held during the second week in September each year, from weekend through the following weekend.  See you there!

Heavy traffic

Those Florida folks just don't appreciate a warm September sunny day in New Hampshire!

Can't start em too young, though

SEE STEAM HAPPENS #19 (ABOVE) FOR MY TAKE ON A SWASH PLATE ENGINE

At Cabin Fever January 2008 I met with Joe Ritter, a very clever engine designer from Mt. Airy, MD
Joe presented a new engine he designed which he calls a Pogo-Stick.

He also displayed his 6 cylinder, single-acting swash plate engine that I'd love to see scaled up for a full scale boat.

The use of a swash plate, the radial arrangement of the pistons and the direct alignment with the prop shaft would make this an ideal small power unit.
Click on the photo below for more details and movies of the engine in operation.

Here's a photo of Peter Renzetti's Swash Plate engine

This one uses a shaft-ported valving, much as used in 2-stroke model airplane engines.

In the picture below the pistons are all retracted. When pressure is applied they each move to contact the swash or wobble plate.

Here's a rough diagram of Peter's valve porting

Watch out! there are 3D pictures in this collection

  How to view the stereo shots.

If you are over 40, back about 6 feet away from your screen (If you are under 40 stay right where you are).
Hold your left hand vertically between your eyes with the base knuckle of your index finger touching the tip of your nose.
Close your right eye and check to see that your left eye can clearly see the left picture. The close your left eye and check to see that your right eye clearly sees the right picture.
Now comes the tricky part.  You actually have to relax your eyes enough to cause them to diverge (this is the opposite of crossing them).  The eyes point outward a bit.  This may take 5 or so minutes the first time, but becomes easier with each use as your eye muscles get some practice.   Eventually you should see a third image form between the two real images.  This middle image will be 3D and should be right behind your vertical hand.
Get you hand out of the way by moving it downward and out of your vision and you should be able to hold a 3D image....
Some people take 10 to 15 minutes to master the art.  Others can get it within 5 minutes...There are a few (about 5%) who can't do it....But if you were able to see those "random dot stereograms"  Magic eye images that were popular about ten years ago you can do this...It's the same skill.
Once you can free view the photos easily you can try getting closer to the screen.
