Yep, it's another of my attempts to revolutionize woodturning and become rich & famous (likely poor & infamous) without doing myself in. Anyway, hope springs eternal and most of you will at least, have heard it first here. :)
I ground a copy of Soren Berger's Viking hollowing tool from the catalog pic this morning. Seems to be a sort of tiny hook. Whatever, the Viking does work very well for end grain hollowing. I also broke a 3/8" twist drill and being of Scottish descent, I couldn't throw it away. I noticed the bit's vague kinship with Soren's Viking and a light came on. Well, at least a small candle was lit!
Ground the cutting end of the broken drill bit into something roughly resembling the Viking and fixed it in a handle. Began hollowing a NIP end grain Berger kitchen cannister in which I had predrilled a 1" center hole. Worked fairly well, but after grinding a few shapes and searching for the sweet spots, I hit on a really good hollowing tool that's worth more than the bit. I can't post a pic, but experimenting with various shapes in making one was part of the fun and using my final best shape was a kick. Try it, you might like it. Experiment with your own variations of shape and presentation. Remember to put a tiny arris on the front edge.
Of course, this is only for those who enjoy making things _for a lathe as well as making things _on a lathe, so it offers no competition to Soren's fine little hollowig tool. If someone should make an 'Arch Pinch Penny' that works for him/her, please post a pic and comment pro & con.
