I can see the reasoning for buffing, yet like TWiG, so far I've hand rubbed finishes on bowl and spindle work... most have been oil.
When I see the advantages with the work posted, I've considered buying a set/system, untill the past 2 days at Axminster Nuneaton Store, with watching Colwin I noticed with interest He used just 2 wheels, 1 compound and wax only .. not 3 as seen usually.. Asking Him, he was puzzles .. 2 is all it took, why the need, when I mentioned diamond white (if that's the compound !!) as used in between, before the wax.. it would appear to be a step (and time saver) which is not necessary to achieve the desired finish.. if so I see the cost come down with just 2 wheels, an a 1st cut compound, as I've a stick of carnauba wax, may well be bees wax mix. Then is this just the view of one man and unfounded, even for Colwin's years in the Trade/Craft.
We find so many advancements happening, the latest or newest ways and means.. is 3 wheels just a money making gimmick or is it necessary .. after all we've all got boxes full of as many unused, as used tools which were, again a must have if we're a Turner to work, it only takes a few and at best a time saver from hunting for and using many, which is an advantage to efficiency.
Food for thought..
