Also Nick most "dog box's" have straight cut gears that are noisy as apposed to helical ones to lessen power loss, but as others have said (and I can vouch for it) not that strong if abused as I was forever welding the edges back on the dogs and reshaping with the angle grinder !!!!!
A lot of people don't understand how a "constant mesh" gearbox works that is fitted to just about every manual car, every forward gear is in mesh with the layshaft but is not actually doing anything until you engage a movable hub on the mainshaft to lock whatever gear you require that up until now revolve freely.
The same applies to dog or syncro engagement boxes.
