Well its Christmas and hope all of you here have or had a great time ...............We got up and opened gifts and the kids took off for friends until Christmas dinner later in the day. So, I helped out around the house and had about 4 hrs or so to myself so I headed out to turn something.
I decided to try to turn something large and long so I took some measurements to see what the max would be based on how deep I could go with my forestner bit and extension. I came up with a boring depth of 2 feet. Mounted up a decent size log and rounded it - put a tenon on it - flipped it around - attached my steady rest - set up a long drill bit and drilled to depth - then set up a 3" forestner with the extension (i have a bed extension on my Jet lathe) and started boring it out. Boring was into endgrain and it did take a bit of time - boring at 600-700rpm and 1/4 to 1/2 turn at a time until I got to my required depth. This was about the max I could do with the headstock all the way to one end and tail stock at the other with the forestner and extension in place - there was barely any room left before the bit would enter the pc.
See pictures below...............
Pic 1 - setup
Pic 2-3 - roughed turned and now inside to dry - total height from bottom of vessel to top is 2' 1/2"
Question: If I wanted to make the vase longer in length than the 2' im thinking the only way would be to buy a longer drill bit from somewhere and drill it out to depth by hand...........thoughts or has anyone bought a longer bit ?......im not concerned about the travel from the drilling as it will be hollowed out anyway.
