Thanks for the comments they left me wondering if a hollowing tool I made would be of interest.
I made this a couple of years ago

Ash handle, stainless ferrule, steel tool bar, an old bolt machined to make a cutter holder & give articulation & a Little brother cutting tip & shield.
This has worked quite well but has always been very aggressive in use & whilst pondering why I came to the conclusion that the cutting edge was too high & would be better if more inline with the center of the main bar.

So this afternoon I thought I`d see with the aid of a mate if we could come up with a better solution.
Here are a few photos of what we did.
Starting with a block of tool steel the ¬_ shape was milled

Initial milling finished

After which the holes were drilled & taped & the ends radiused.
Reassembled the new articulated section looks like this.

Much more inline with the center of the bar & able to articulate nicely

I`m hoping to try it out tomorrow before doing any further fettling so I can see first what, if any, improvement it has made.
Cheers.
