Have been told that using reverse on my quaife box should be noisy (sounds like someone on speed loudly hitting the bottom of the metal
bodywork/chassis with a hammer) because of the shape of the gears.
Is this true?
certainly is 
the nice quite ones are the allens r and d boxes never used one myself as £1400 
but they do hold the record for fastest speed in
reverse somthing like 100mph
forgot to add
do a search on here you will find it often talked about the sound of clunking / nocking, if i didnt live in such a hilly area i wouldnt have one but
at £700 pounds its the cheapest / easiest way of a high torque reverse unit
best regards

If they are straight cut, then expect a whole load of extra noise. Although it will let ever know when you're winding it up!

been away for w/e so couldn't get back to you sooner. Does the noise do any damage, the knocking is really loud? ie do the boxes last very long,
or are they easily fixed?
Excuse my ignorance, if anyone ever wants to know anything about, errr, woodwork then I'll be right there to help.
No harm will be done, it's just that straight cut gears make a lot of noise. Helical gears are quieter, but weaker due to the sideloads imposed by the design. Instead of having gears that are mostly meshed all the time and don't "slap" against each other, the straight edges have a slight clearance which disappears under load. They can be loud, but you will like the noise! It's a high (ish) pitched whine when under load and they will chatter when cruising as you come onoff the power.
It should sound a little like this

Weird, I replyd to this but it seems to have been removed?
Anyway, thanks for the details on the gears and the tunes. There is definitely something amiss as it really does sound like something hitting the
metalwork.
It is off the road at the mo so can't check it yet, there were more urgent things that need attention. Will let you know. Thanks again.

Have you checked that all the mounting bolts are done up properly? IE is something a bit loose and hitting things? If your not sure, look for shiny patches on the tin work which should show up anything rubbing.
