I have been running into a problem when i hollow vessels with my hollowing rig and thought i would put some information out here to see if anyone can help or has any ideas. I get alot of catches/grabbing when hollowing and have been trying to figure out why its happening.
****I hollow around 600-800 rpm and sometimes higher
****sharpen the tool before and druing the hollowing
****clear out chips every couple cuts with air gun
****cutter is set center off the tool rest
****tips are cut to approx 50' angle using a platform on my grinder and the tip is rounded like a scrapper
****tried to use only pulling cuts from center out - and working in sections - the most catchy/grabby area is the side at the widest part - happens with every vessel
I have posted pictures below of the normal type way i set up prior to hollowing for reference - and i usually have the tool rest and the rig set closer when i start
I recently ordered a goose neck tool for my Monster hollowing rig and they were a great help in suggestions to correctlng things but i want to see what other people are doing or if they had the same problem - even after the suggestions today im still having the same problem...wondering if i need to sharpen the tool differently
