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.

  • brass strips cut on the bandsaw

    Cutting Brass on a Bandsaw

    Cutting brass on a bandsaw can be difficult and so I devised this simple modification to overcome two of the main issues. My solution was to fit an MDF board on top of the cast [more…]

  • tin of cotter pins

    Cotter Pins

    Cotter pins or split pins are half round wire pins that are formed such that they can be pushed through a hole and the legs then bent to stop them sliding out. This means they [more…]

  • traction engine rear hub

    Rear Wheel Hubs

    The rearĀ wheel hubs for the miniature traction engine that I’m making need to be indexed with eight spokes each side of a single wheel. The trick is that the spokes are out of “phase” and [more…]

  • engine valve stood on caliper

    Air Intake System

    The air intake system channels clean air and fuel to an internal combustion engine. The primary function is to channel clean and cool air to the engine. In indirect injection engines the fuel is added [more…]

  • 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…]

  • SEO image for engineering post

    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…]

Workshop

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