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.

  • single throw crankshaft

    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…]

  • a cast iron flywheel

    Flywheel Design Principles

    The wheel on the end of the crankshaft that gives the crankshaft momentum to carry the pistons through the compression stroke. Normally constructed from a heavy steel or iron disc. A flywheel has two main [more…]

  • fuel cell diagram

    Fuel Cell System

    I was reading an article about using a fuel cell energy storage system for a drone and how it was a high energy density option. This made me wonder how a fuel cell works and [more…]

  • rear wheel treads machined

    Rear Wheel Treads

    The rear wheel treads on these 97mm diameter wheels are just 0.75mm thick and so after some consideration were designed as a machined feature rather than a riveted tread. The rim itself is just 2.75mm [more…]

  • Stirling Engine

    Stirling Engine

    The Stirling engine is an external combustion engine. Also known as a Hot Air Engine. The Stirling engine was invented in 1816 by a Scotch clergyman, Robert Stirling, as a competing technology to the steam [more…]

  • rear wheel rim blanks being machined

    Rear Wheel Rim Blanks

    The wheel rims for my miniature Burrell traction engine. I originally wanted to buy some 4 inch diameter steel pipe with a thick 0.5 inch wall, but I just could not find any and so [more…]

  • traction engine boiler angle

    Steam Boiler Angle

    I’ve been looking into the angle of the steam boiler on a traction engine relative to the surface that the engine sits on. This angle is always biased downwards towards the firebox. Having measured a [more…]

  • CAD of a shock absorber and over type spring

    Mechanical Shock Absorber

    The mechanical shock absorber is a mechanical device designed to smooth out or dampen a sudden shock impulse and dissipate kinetic energy. The shock absorber turns kinetic energy into thermal energy within the working fluids [more…]

Workshop

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