Just a quick note to let anyone who might be interested, know that I now use a negative rake scraper with my hollowing rig. Up till recently I was using a tear drop shaped scraper sharpened in the standard manner but found that on occasion it was just a little grabby.
I thought why not make it into a neg rake scraper so I ground it to about a 60 degree included angle.
After changing the angle the center of the scraper was no longer on the center line and to make up for that I just added a small brass shim under the scraper. I think it is still slightly below center but it seems to work just fine for me.
Seems to work just fine for me.
