Today i fiinished up the little things and tried the rig out on a much larger pc of olive wood. I took off the safety stops and wired up the laser to test it out (5 volt laser from Laser Land). The log is 15" long and 12 1/2" wide.
I drilled a deep hole with a old bit I had by welding in a pc of drill rod (see picture #1).
I hollowed as usual by hand for awhile and then setup the rig as shown in the pictures below (pictures 2-5) . It cut great until i got about 2/3 of the way into it and then it started acting very jerky. I tried raising up the tool rest but it didn't seem to work and then tried rotating the cutting tip down slightly - didn;t help either... I had to reposition the cutter several times due to the jerking tork that the tool was getting.
What im wondering is if I should have made the cutting tips so they just solidly mount into the 3/4" round bars instead of the adjustable one ive been using (picture 6). Like taking the bar steel and putting a 45' hole in it with a set screw to hold the cutter and I could do the same for a straight tool...........thoughts ??
Anybody have any other ideas ????
