Small is subjective. Ask Andrew J about his machines – not exactly small, but still used for hobby work.
But, there again, some have rather larger machines than Andrew J just because they were cheap, robust and adaptable.
Reading that para. , they have missed a comma btween boat and model which may slew the meaning slightly. No reason why all model engineers have to use ‘powered’ machines to make items – unless hand power or man power is included.
Were ‘simply build from supplied parts’ kits for model aeroplanes included as options?
If it had read ‘Readers interested in making …. ‘ that would properly encompass the hobby, I would have thought. Just to go and peruse the models and offerings would be attractive to a wider audience than just the real hobbyist makers of such items.
