Pictures of my machines.
« on: July 10, 2020, 09:01:36 AM »
In loose arrangement I would like to show you here the pictures of my machines.
There will be Steam Engines, Stirling Engines, Tool Equipment and other small parts.
In the last 30 years a lot of different things have come together.

I would like to start with my first work. This machine was made with an Emco 3, with milling accessories.
It is a combination of different designs that I found in books.

The next machine I ordered as a material set from the manufacturer Regner and also worked with the Emco3.
I modified the machine a bit and made the cylinder diameter to 16mm.Furthermore the crosshead was changed and the crankshaft was enlarged a little bit in the dimension. A somewhat larger flywheel was also installed.

Nice  :)

Unusual to see a horizontal engine with reversing gear.

Some of you may know the next machine. Trojan of Reeves.
This is a machine I made on a metric scale. For this purpose I have modified the original drawings and adapted them to the metric system.
The machine drives a small generator which gives power to a street lamp.
The generator was made from a bicycle dynamo.

I built two steam feed pumps for 7 1/2" locomotives for a friend last year.
Steam piston diameter 30mm.
Piston stroke 40mm.
Water piston diameter 16mm.
The pump body was made of bronze. The covers were made of brass. Piston rod and pilot piston are made of stainless steel.
The total weight of a pump is about 1,7kg.
The total height is approx. 170mm.

Some years ago I built a universal grinding machine.
First I planned to build the tool and cutter grinder "Quorn". The castings were very expensive at that time. So the project was stored in a box for a long time. By chance I got the plans of the "Bonelle" in my hand.
This machine I built then.

More pictures.
The machine was manufactured completely without prefabricated castings.

In the book "The Model Engineers Workshop Manual by G.H.Thomas, I found a drawing of a "Banding Rolls".
I converted this drawing into the metric scale. The author of the article suggests gears with 20 teeth and 20TPI.
I used gears with module 1.5 and 17 teeth. The center distance changed by 0.5mm.

Over 20 years ago I visited the model building exhibition "Intermodellbau Dortmund".
There I had contact to a dealer, who sold me for a small price of €,- cast patterns of steam engines with bayonet frames, which he had built.
It was a one cylinder engine and a two cylinder engine.

Well, all machines shown were built by me in the last 30 years.
This is the last small series of steam feed pumps for locomotives of gauge 5". The first series I put on 1994. There were 15 pieces at that time.
I produced this last series in 2007 with a total quantity of 7.
They are small self-starting, flywheel-less double acting steam pumps, which have a 16mm steam piston diameter and the water piston is 10mm. The stroke is 22mm. The pump is of the type "Westinghouse".
In the lower pump body there are two suction valves and two pressure valves.
The total size of the pump is 115mm.
In the last year I made two more, slightly larger pumps for a 7 1/4" gauge locomotive.
These pumps have the dimensions steam cylinder 30mm, water cylinder 16mm, stroke 40mm.

In 2016 I built the Pillar tool by G.H.Thomas.
I found the drawings in his book "Workshop Techniques".
I did not use any cast blanks for the construction. The complete device was worked out of solid material. Some parts I found on the scrap metal. Other parts I bought from steel dealers.
Since I can't work well with the imperial measurement system, I converted all measurements to the metric scale. This will inevitably result in very unfavorable dimensions. All measures were then rounded up or down.
But see for yourself.

Thanks for the photos of the pumps. Always thought about putting a pump on one of my locos but never have. Would be interested in seeing one of your pumps fitted on a loco. Are the pumps to your design? Great work.

The principle of the pumps was developed by H.Wittman, who unfortunately has already passed away. But I redesigned the pumps and adapted them to the appropriate scale.  I don't have any drawings, only rough sketches of the function.  At the garden railroad workshop in Germany there are still drawings by Hans Wittmann.
