So much depends on the eye of the beholder! The roof of my Garden Shed needs replacing and I'm into 3D printing. Don't intend to do any scraping, but always useful to know about tools and techniques. Although I'm unlikely to adapt a Shell Arbour, modify a chain, CNC any gears, or tension a band-saw properly I always read such articles to see how its done, and often pick up good ideas. Rewinding motors scores with me and I'm deep into the Free Pendulum clock. Vehicle work isn't my thing, but I have a go sometimes. Haven't been to the Science Museum in since 1970, and really should!
For me this issue was a good mix, which is usually the case perhaps because I have wide interests. Been taking MEW for several years and don't recall any I thought were a waste of money. Every so often an issue arrives which ticks all my boxes, whoohoo. I find Model Engineer more variable, but that's because it covers Model making, which isn't my thing. Still worth buying though. Tried Engineering in Miniature several times without enthusiasm: pretty sure it's because they focus on aspects of the hobby I don't care about. Me rather than them.
The ads are useful too. Ordered a copy of 'The Secret Horsepower Race' a couple of weeks ago without realising it's a Morton's book. Fortunately only cost slightly more than their offer price, or I'd have been miffed!!!
Book recommended if you want to know about high-performance piston aero-engines, how difficult they are to design and debug, and the importance of fuel chemistry. Octane numbers are rubbish!
Many of know the story of Miss Shilling's Orifice but how about the BMW Kommanogerat? It's a mechanical Engine Management Unit, made years before electronic versions were cheap enough to put in cars. Has anyone ever modelled one?
