Wow, these things are fantastic, my captured bar hollowing rig loves them! I'm easily halving the time it takes to hollow a vessel with these as they cut away the excess wood so quickly and effortlessly and leave a decent finish from light finishing passes. All this is easily done through a hole of less than an inch across. They are easily the least 'fancy' looking hollowing tools I have tried and by far my favourite to date!
The piece pictured to the right of this text was the first thing I have hollowed with them, a fairly basic shape
made from a piece of fairly rotten Elm(well half rotten, the lighter half in the pic!). I was so impressed with the hollowers I put another 'better' piece of Elm on the lathe to make a wider, flatter form to test how the Keltons could reach far into awkward corners. Using my captured bar rig I could only reach within half an inch of the desired thickness right at the shoulder, so I put the most curved hollower in a tool handle from one of those expensive hollowing tools and could easily reach all the way. The best bit about this was that they work as a handled tool just as easily as they do in the rig.
This second form was turned side grain as the Elm has such a wonderful stripe to it in this orientation. The lid is a piece of ebonised Beech and the finial is turned from 6mm diameter aluminium bar.
The bottom line here is I wish I had the Keltons right from the start, I have four other specialist hollowing tools, two of which were pretty expensive and in my very humble opinion they don't hold a candle to these beauties.
