Is anyone hollowing resin forms? If so what have you been using to do the hollowing? I am typically scraping with the some scrapers I used to use inside wooden forms but continue to get chipping and am not happy with the end result. I am using a hollowing system which generally holds the tool on center line so I am wondering if I was to regrind a scraper to a NR will it function and would I then need to raise it so the cutting edge would be on center? The Kobra system I'm using does not lend it's self to a change in height. Any suggestions? Oh and I usually try to hollow through as small an opening as possible based on the depth of the form.
