How to Keep the Model Engine in Their Best Condition?

Keeping your model steam engine and boilers in good working order is important for obvious reasons. This is not really particularly difficult it is more a question of making the effort to do it. Attention to good lubrication is a good starting point, lubrication is essential for almost all mechanical mechanisms, take the time to study and research the lubrication requirements of your particular engine it can make a big difference to the performance and life of model steam engines.

Boilers generally don't need a great deal of maintenance, providing distilled water is used then there should be no deposits of calcium to contend with, calcification is one of the worst enemies of boilers the buildup of lime scale can block pipes in worst cases and also acts as internal insulation which will adversely effect the performance of the boiler. This can be removed retrospectively with the use of a weak or dilute acid but be very careful as acids may well adversely attack the materials the boiler is made from, commercially available kettle de-scalars can be a good as generally they are gentle and sympathetic to metals.

Where ever possible follow the manufactures guidelines when it comes to care and maintenance if unsure then contact them if possible.

Below are some steps you can follow to enhance the life or your models.

Dismantling; the pros and cons

As a general rule it is not good practice to start dismantling engines and boilers unless you have a good understanding of the subject, it is quite often the case that innocent tinkering can result in more problems than you started with. A good first step is to contact the original manufacture if this is possible and ask their advice, if this is not an option then member's of clubs, and there are many, can often offer assistance and guidance.

Cleaning

Cleaning your engine frequently is good practice, firstly it will keep it clean and maintain its appearance and secondly it is a good way of detecting any wear or other issues that may be evident. Hot water and detergent is probably the best way of removing oil and dirt from components, solvents should be avoided as they can attack seals within the engine and may in extreme cases affect any paintwork present. Tooth brushes and cotton buds (Q-tips) are a good way of getting into those hard to reach places.

Lubrication

Good lubrication is essential for any mechanical device and particularly so for the steam engine as some parts of steam engines operate a high temperatures and require specific oils, a model compound steam engine for instance as a number of cylinders operating at different pressures and therefore different temperatures. Oils for cylinders often have additives which enhance their performance at high temperatures and pressures. On the other side of the coin parts of the engine will remain quite cool and can safely be lubricated lighter oils such as just plain motor oil.

This is some very basic guidance on how to care for model steam engines which it is hoped will be both informative and useful.
