Last year's "SPLIT MONO" engine was a unique effort and a successful build. What would a two cylinder version look like? There are two ways to go here......and inline twin with both cylinders on one side of the crankshaft or a cross cylinder design, like an opposed engine with one cylinder each...

A single cylinder engine with twin crankshafts. This split rods concept actually exists in the marine and motorcycle world.

I have a pair of single cyl. models in my collection. Want to add another......and show something that most likely, you have never seen before! Can you power up two crankshafts with one cylinder? 🤔 The SPLIT MONO story coming soon!

Let them know what you do! :) Sum guy that builds models!

Moving parts around to gain a lower profile stance on a vertical engine. THREE BELOW's story coming this weekend! 🙂

Expanding on an iconic model engine design.

This image giving me and inspiration for a new model. 🤔 ....exactly how far can you place those valves from the combustion chamber anyway? The SILO engine build coming up soon! 🙂

I've been looking at my iconic Webster periodically the last couple years. With an idea in mind..... 🤔 What if Joe Webster designed a twin version? Not too many horizontal gas engines favored in the forums beyond hit and miss. This fall was the year to develop that concept with just enough...

A VIEW BACK ON MY LAST FEW YEARS OF MODEL ENGINE BUILDING. TWO, THREE AND FOUR CYLINDERS. SELF DESIGNED AND BUILT WITH A SENSE OF UNIQUENESS OF FEATURES UNCOMMON IN STANDARDISED MADE TO PLAN MODELS. ENJOY THE PRESENTATION!

A pair of 180deg crank twins combine together on a centralized flywheel shaft for a rare configuration engine, the Square Four. From LONGBOY ENGINE.

A rare configuration in I/C engines is the square four. From the motorcycling world in the form from the British Ariel S/F classic for three decades....... .....to Suzuki in their GP500 racing campaign years in the '70s thru 1990. Can I do this configuration as my usual industrial utility...

Inline triple. Unusual transverse crank drive. Valve blocks. Geared crank segments. Right angle cam drive. Verticle fuel tank. Dual fan cooled. Build log.

Build season came early for me this year in August as the virus changed my routine and I needed some around the house activities to come into play long before the cooler weather comes for my usual involvement time with modeling. So I begin with a concept. I've taken one of these and put it...

I got a phone call last month from "Bob Thomson" over at "NOR'WESTERN LOGISTICS"' They are a maintenance and infrastructure support company for the mining, lumber and oil industries and service U.S. and Canadian firms. He tells me that the little single, "Sentinel" engine I developed for them in...

If you look up "side shaft engine" on the internet, you get all your contemporary snow blower and rototiller utility engines displayed. For antique engines, the term refers to an external shaft driven by the crank to operate the valvetrain, provide ignition, drive a lube pump or engage a speed...

Trying out a sideline as a plumber with my first liquid cooled model. More parts and more area needed on the frame for those parts, Black Water turned out to scale with these external additions. Don't think I will return to L.C. soon..... but gave me a chance to try out another cooling option...

A center flywheel concept of a OHC twin overhang crank engine. Started with cordless drill at the camshaft.

Getting hard to create new engine designs or layouts, something you haven't seen before. Maybe you've seen something like this! I can't find it on the Internet. Maybe this engine is something I can call my own then. So how bout a multi cylinder inline engine.....with a right angle crankshaft. I...

Forced air cooled, cross valve heads.

An air cooled, cross valve 360 Twin in the inventory now. Bigger pistons, heavy duty crankshaft, some cast iron and maybe a couple items you have not seen before. The Internal Breeze story starting this weekend.
