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...

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...

I'm having trouble finding a pressure sensor at an acceptable price ie not more than 50 dollars. I need it to provide an analogue signal which indicates the pressure of air or of steam in the range of 0 to about 8 atmospheres. I think I could manage to encapsulate a naked sensor in a suitable...

If you haven't seen it here is a short video of an amazing 240 year old machine which does longhand writing using paper and ink and which is still working! Wow! http://www.chonday.com/Videos/the-writer-automaton

MY TWO CYLINDER ENGINE IS FINISHED This post shows some photos and a video of the completed engine, the build progress of which was reported in the thread A Two Cylinder Steam Engine. I have updated all the drawings to reflect the engine as built. Rather than create new places for these...

A TWO CYLINDER VERTICAL STEAM ENGINE INTRODUCTION I have resumed building the steam engine I had started when my encounter with HMEM caused me to embark on a fruitful interlude of tool building during which I learned much and for which I will always be grateful to HMEM and it's members. This...

SIMPLE FILE GUIDE - A VERSION FOR QUICK CHANGE TOOL POSTS Since I now have a QCTP and greatly appreciate its convenience, I get unreasonably annoyed when I have to take it off to remount my old monotool holder because I need to use an old tool for which I haven't yet made a QCTP holder. In...

BAYONET BACKPLATE FOR MY NEW CHUCK I have long felt the need for a chuck with 4 independently movable jaws and, needing it to make my QCTP, I finally ordered a 125mm Sharp from Chronos, UK. Four days later it had arrived in Rome. In the meantime I had purchased a 21mm slice from a 130mm bar of...

This post briefly describes a simple system for cooling and lubricating the cutter and work piece being machined on my lathe. The need for some cooling became apparant during the rough machining of the steel chunk destined to becaome the Body of a Quick Change Toolpost (see thread "Another Quick...

This drawing shows a tool "Simple File Guide" which supports the use of common or garden files under muscle power to make flats on round sections or cylindrical segments on flat sections with significantly better precision than can readily be achieved otherwise. In conjuction with a dividing...

This post describes a tool "Simple File Guide" which I built a few years ago and which may interest folks who, like me, have a lathe but don't have a milling machine. It supports the use of common or garden files under muscle power to make flats on round sections or cylindrical segments on flat...

What a marvelous mine of information and stimulus HMEM is! Before becoming an HMEM member I hadn't encountered the idea of Quick Change Tool Posts and so calmly accepted the time needed to change tools in the one place post that came with my lathe when I bought it in 1985. I had encountered...

In my hello post in the Welcome section I promised to post pictures of engines made in our father's workshop by my twin brother and me as kids. To post the picture I have tried to follow the instructions in the first topic of the Photos and Videos section - hope it works. It shows two double...
