Model Making

I spend hours making many different types of models and I find this is a great way of relaxing. It’s also a constructive element where I end up with something that is rewarding for years to come.

A simple chair at 1/12th scale with a seat woven from bamboo.

Or the 5 cylinder rotary engine that has taken 100’s of hours to construct.

All of these models have their rewards in the process of making and as objects to look at.

My gallery page lists a large number of my models.

 

 

Knowledge

There’s always a lot of information and tables that are needed around the workshop and that are helpful in the field of general engineering and so I’ve started to list those under the heading Knowledge, a great place to start is with the Engineering page itself.

  • marble run

    Corrections Needed for Marble Run

    The marble run is working rather well, but now I’ve been using it for some time I’ve realised there are some issues. The trouble is I keep forgetting the issues and so I thought I [more…]

  • 1/4 inch spark plug

    Engine Ignition System

    When we talk about the engine ignition system there are two fundamental types: compression ignition spark ignition. This is the system for igniting an fuel-air mixture that has been compressed in the cylinder by the [more…]

    Model Engineering SEO

    What do I mean by Model Engineering SEO? SEO is search engine optimization, model engineering is a hobby that feels very vibrant, but the view is it is dying out. Let’s start with the perhaps [more…]

  • old lead acid battery

    Lead Acid Battery

    The Lead Acid Battery is a battery with electrodes of lead oxide and metallic lead that are separated by an electrolyte of sulphuric acid. The overall reaction is: PbO2 + Pb + 2H2SO4 <=> 2PbSO4 [more…]

  • nickel metal hydride battery

    Nickel Metal Hydride Battery

    The battery has a nickel-hydroxide cathode, a metal hydride (a variety of metal alloys are used) anode, and aqueous potassium hydroxide electrolyte. This is a rechargeable battery chemistry that has been superseded by lithium ion, [more…]

  • lithium ion battery schematic

    Lithium Ion Battery

    In a rechargeable lithium ion battery lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. The cathode is a lithium transition metal oxide, eg manganese or cobalt [more…]

  • boiler endplates and tubes

    Steam Boiler

    A device for generating steam for power, processing, or heating purposes or for producing hot water for heating purposes or hot water supply. I’ve included the firebox within the overall steam boiler as it’s difficult [more…]

  • final pair of rear wheel rims

    Rear Wheel Tread Pair

    My first go at machining a rear wheel tread pair for my miniature traction engine was not that successful. That meant I needed another go. The rear wheel tread pair are handed and the tread [more…]

    Crankshaft Design Principles

    This page lays out some of the crankshaft design principles along with descriptions of the main features. That part of the engine which transmits the reciprocating motion of the pistons to the driven unit in [more…]

Workshop

The workshop / man-cave is the den in which we can master a number of engineering techniques.
