I know Wiedemann make their version of this hook tool that is intended for woodturning lathe machinest (i.e. powered lathes spinning fast rather than slow treadle lathes) and I when I have visited my local woodturning shop, the Toolpost, over at Didcot, Oxford I saw that they sell the Wiedemann Hook Tool (but I can not find them listed for sale on Peter's website - but then he has loads of stuff in the shop that isn't on the website).
There are a couple of video's on YouTube by Wiedemann demo'ing their use
https://www.youtube.com/watch?v=oyDNAGu0rxU (the profile of Wiedemann
straight hook tool is very different to Martel's which I have. With myine I pull from the bottom of the cut - where with this Wiedemann it cuts to the side - but not that
- Although the item being cut is a spindle & end-grain, the cut is peeling side grain
- If you were to hold a hook tool beside a bowl gouge, it has the same cutting tip and cutting edge along one "wing", both with the same bevel
- So the initial cuts shown in the Wiedemann video are identical to presenting a bowl gouge laid on its side with the flute pointing towards the front of the lathe, in a push cut from the middle toward the lathe front when the handle is way over the back of the lathe (as Demo'ed by Stuart Batty at 4:50 here https://vimeo.com/68642331 - but the difference is a hook tool can continue to make this bevel supported cut deeper than a bowl gouge where the side walls of the form would interfere.
https://www.youtube.com/watch?v=dAxmc7pd3kQ explains cranked hook tools - the comments above re. that a hoot tool has the same cutting edges and bevel and the peeling of side grain with bevel support still apply - the rational for the crank in the hook tool is to put the cutting edge back in line with centre line of the shaft and toolrest support
I have the MHT version and there is a full length video of its use and comparison to gouges here
https://vimeo.com/82587061Perhaps you can tell from the above, I am not only interested in how a cut is done (which is often what is demo'ed) - but why, when done
right, it works - hence I like presenters line Andre Martel and Stuart Batty how explain the technicalities
However I can't say I have ever seen a hook being used on a pole lathe, so i have no idea whether they are the same profile or similar, same tool presentation - or whether they simply share a name but are quite different
