Three-Clock Lead Time Estimator

A nylon schedule runs three clocks in series, not in parallel: machining, stabilisation and transit. Most quotations show the first and absorb the other two, which is how a date slips without anything going wrong in the shop. Set the four fields below and this separates them, so you can see which clock is actually binding. Bands are industry-typical for custom machining, shown so you can sanity-check any quotation; your dates come back in a written Zhenling quotation.
