Don't fight progress

If I were a tv character I might be the Lone Ranger. I'm not one for sharing my work, even up to the point of trying to create my own components from scratch. Last night though I learned the value of buying something pre-made and tested from a manufacturer. I'm not spending all my evenings making solonoids!! Although the one I made last night worked fine, I don't want to make another!! I'd rather spend my time making other parts of the engine from bits I can buy off the shelf where possible. 

So eBay has provided and tomorrow I'm going SUP boarding.
