The need of life tooling. Do we need it now with the new Alu inserts bits?

Well, sitting here thinking on the use of a modern lathe together with our
previous discussions about the special ultra sharp Alu-Inserts ealier:

Have any one tried these in a beefy lathe to do tapering of wood (after a
round on the bandsaw to chop corners off) ?

I think it was mentioned that these did peal the wood like a union.

In case this works, I guess the drawback is that feed-speeds need to be slow to make the surface OK..

Any thoughts or experiences ?

I believe the live tooling for tapering and rounding is far less stressful on the wood than trying to peel it like an apple with a single point.
 
Dave;
I guess the stress would depend on the depth of each pass ?

There have been some links to videos here from some vendors where hugh passes has been done and a lot of strain so I guess we could push the limits in each method ?

2:50 in to the video. For me it looks like the wood is jumping a little due to the forces involved, but then that might be just me. Anyway this was not my thought behind the thread :)

John Davis uses a single point to cut his stuff. However, I 150% believe live tooling is the best way to cut wood.

Kent, I agree...it depends on the depth of the cut also. If the wood is jumping with live tooling the bite is too big. A .020 deep cut for me is huge. If I wanted to remove .060 off the diameter, in my mind I am going to do it in 3 or 4 passes.
Also the diameter of the piece will regulate how deep I'm going to cut also.
