MY TRIPLE WOBBLER
INTRODUCTION
This post briefly describes some aspects of the design and building of a three cylinder, double acting oscillating engine which I have just finished. The idea to make a triple wobbler came from a post I well recall enjoying on HMEM about a year ago but which now...
INTRODUCTION
This post briefly describes a model Kimble Engine which I have just finished building. The inspiration to try a Kimble build came from Arnold's masterly build of Elmer's Kimble documented in a thread started in November 2011, and which I discovered in Nov 2015. Here are a few photos...
Hello Dave,
As a matter of fact I did consider pumping some fluid against gravity as a way of providing a measurable load for small engines. In the end I plumped for the Seller Dynamometer technique for three reasons.
The fact that Seller’s idea gets enthusiastic recommendation in...
AN INSTRUMENT FOR MEASURING THE POWER DELIVERED BY SMALL ENGINES
FIRST USE EXPERIENCE
Set up and Approach
For the first serious attempt to measure the performance of an engine I chose the two cylinder engine I completed a year ago, the build log of which is on this forum.
The diagram...

THE PRESSURE SENSOR
Following advice received from several HMEM members I ordered a Honeywell TruStability series sensor from Mouser. These are piezo-resistive silicon pressure sensors with integrated electronics to provide...

AN INSTRUMENT FOR MEASURING THE POWER DELIVERED BY SMALL ENGINES
INTRODUCTION
This thread briefly presents an instrument I have developed during the last year to try to measure the delivered power of the small steam engines I have built over the years. I took the basic idea for the instrument...
