Saunders spin casting machines

I’ve starting running a series on my personal blog on the Saunders bob-weight spin casting machines I use at Fighting 15s. I’ve never been able to find out much about the machines, made by the now defunct N Saunders Metal Products Ltd. This is my personal experience of using them to get the best results, and the articles have been prompted by the acquisition of a second machine that needs repairing and refurbishing. Other users’ mileage may well vary.
