Buy/Sell/Trade / Rider Engine *mostly* Complete Casting Kit - $250 OBO
« Last post by ahowell on January 18, 2018, 05:21:32 PM »
I found this "Rider" pumping engine casting in some of Dad's "stuff" boxes.  The base says "01/50" but Dad's is actually #1.  This was a sample so the castings may not be perfect, but they look good to me.

This casting kit contains the following items:

Engine Base Casting
Upper Frame Casting
Lower Frame Casting
Furnace Door casting
Crank Arm Casting (2)
Pump Outlet Valve Cover Casting
Pump Inlet Valve Cover Casting

See attached photo.

E-mail me at if interested.
Buy/Sell/Trade / Fuller & Johnson Hit & Miss Casting For Sale
« Last post by ahowell on November 22, 2017, 02:17:17 PM »
Dad purchased this Fuller & Johnson casting in 1993 for $350.  I've been told it's probably worth $550 now.   It's been sitting around for almost 25 years collecting dust and now has a little surface rust.  I have the most rusty side of each part exposed in the photo, so the back sides of each part are less rusty (or none at all).

Flywheel diameter is 9".  Included are 11 pages of drawings on 8.5 x 11 sheets, plus two Fuller & Johnson decals.  It will ship in two USPS Large Flat Rate boxes costing $18.85 each, so we'll round this up to $40 for shipping.

If you are interested, send an email and I will send you a Paypal invoice for $590

Here are some notes I made as I was cleaning up the drawings.  Theye might help explain some of the stuff the drawings dont show.

Allen thanks for the support.

I received this e-mail from Hogan Liechty back in Aug '17:

I am in the process of designing and building a single cylinder overhead cam 4 stroke model engine loosely based on the design concepts of Jerry's V-Twin.

I have not directly copied any of Jerrys designs but I have used them for inspiration.  Jerry's V Twin was the most difficult yet satisfying build I have completed.  Mine runs great.

Because it was so difficult to build the gear train and I wanted to try designing an overhead cam engine, I designed a single cylinder using Jerry's basic crankcase, cylinder, head, and flywheel concepts.  My final goal is to design a V-Twin OHC engine using the same concepts.

The obect of this e-mail is to give credit where credit is due. I have no desire to profit from my design work but would like to share it with the model making world.

I would be happy to give you a copy of my designs in PDF format and you can do with them what you want.  They are by no means ready to market on your web site since they are for my own shop use and are not fully detailed. If you want to complete them and make them market ready feel free to do so.  All I ask is aknowedgement  for the concept.

I am almost done with the build and will be trying to start my engine soon.  I have also shared part of my build on HMEM forum and have tried to give Jerry credit for the design concepts I have used.

I will attach a couple picture to show what I have done.

Please let me know if you want the drawings and will send them to you as soon as I have my engine running.

Got this email from Matt Parker on July 4, 2017.  Click the youtube link at the bottom to see it run!


Thanks again for helping me to solve my hall sensor problem. Even though it wasn't anything more than a bonehead move on my part, it was you who insisted it was the hall sensor leading to me finding the issue.
The below video is my engine finally taking its first breaths of life. Thanks to your father for a great set of plans which allows folks like me to accomplish these builds. I look forward to the next engine build.

Thanks again,
Matt Parker
"Farm Boy" 4 -Cycle Hit-&-Miss Engine / Missing crankshaft/bearing hole?
« Last post by ahowell on May 04, 2017, 06:09:04 AM »
Here's a valid question I received from Richard Piaseki on May 1, 2017:

I just bought the plans for the Farm Boy engine and after reviewing the drwgs., I have a question. Sheet #3 does not show a .500 hole for the crankshaft/bearing. Is there a reason for this or just an omission error?
Richard Piasecki

I wasn't sure, and I also noticed a similar issue with the connecting rod end, so I asked "EngineMaker' (builder of Farmboy #3).  Here's his reply:

On page #3 your Dad gave the dimensions for the placement of the holes as 1.820" from the back edge of the frame and 1.280" from the back of the lap joint. Now the size of the hole is the .500" dimension shown on the crankshaft bushings shown on page #9. Half of the hole is in the bearing cap and the other half is in the frame. I drill and ream my 1/2" holes as the bearing should be captured by the bearing cap ( so it doesn't spin) bur not crush the .376" inside bushing dimension.
On page #8 if you look at the connecting rod drawing, the bottom of the connecting rod dimension is .400" wide and the cap is also .400" wide. The hole goes at the seam of the 2 parts and in the center ( the .900" divided by 2 = .450") from  the edge. The hole size is the .561" dimension shown on page #8 as the rod end bushing. You could actually make the hole drilled an reamed .562" and the bushing .561" dimension .562". In this case the rod cap bolts going through the bearing keep the bearing from turning. My guess is that your Dad meant to say "Drill and Ream a .562 hole through rod big end" instead of .282" as shown on the rod big end assembly picture shown on page #8.

Here's an e-mail I received from Steve Gould on Oct 3, 2016:


Hi Allen,
My Howell V2 engine is nearing completion, it’s a handsome looking engine and a bit more difficult to produce than my original assumption. There is still a number of steps to go before completion, but all the main parts are working fine and the cam gear train works very well. Here is a picture, it looks the part when polished!
"Vintage" - Stirling Cycle Engine / Re: Photo of "Vintage"
« Last post by Wittentry86 on August 28, 2016, 07:19:27 PM »
" 'Vintage' is a 90 degree engine with a horizontal displacer cylinder and a verticle power cylinder. Connecting rods for both cylinders us a single crank pin. This makes for easy construction and interesting rod motion. The engine frame (blue) is made from aluminum plate, most of the rest of the engine is machined from brass or stainless steel bar stock. Most of the brass parts were nickel plated, but that is not needed in any way - just cosmetics to suit me!

Read this phen375 review to find best fat burner.

Vintage makes a perfect power source for the Miser engine. As such, it is water cooled and a belt powered water pump circulates the warm water through a ring that Miser sits on and back through the engine again. This powers the Miser while the Miser becomes the cooling 'radiator' for Vintage! Just about any other simple radiator can be used such as a 10 foot loop of vinyl aquarium air line tubing, etc!" - Jerry

Here's a photo of "Vintage":

that vintage is really something that is worth of every single penny. i always wanted to have one of that and you are very lucky to have one. the fact that vintage really makes a power source for MIser engine, that is really for me makes it standout from others.
