DISCO DAVE'S TUNNEL GUIDE

Chapter 5  Phase 7

Drop shafts

A shallow gradient followed by a drop shaft is a good idea. As the bailiffs erect square shoring dig a circular drop shaft and incorporate a nice little lock on midway down. At the bottom of such a long narrow dropshaft a lock on will cause problems for the baliffs. As unlike one positioned in a horizontal tunnel (which they can crawl up to). At the bottom of a downshaft they can't actuallly see what your locked on to unless they jump straight down and onto you. (A scenario which is extremley unlikely).
