> In that video,the lathe is turning counter-clockwise,or towards him. This allows him to be using the Tina blade on the operator's side of the lathe. Trying to do what he just did on the back side is asking to have the blade jerked out of his hand,and sending either his hand or the blade into a spinning chuck.
This phenomenon is also true in reverse,if you set the lathe to turn clockwise,the safe side is around the back,and out front is where you can get hurt. My machine turns clockwise unless I reverse it,and while trying the method where a utility knife blade is used,but done out in front,the leather kicked the blade back. It jerked my hands towards the chuck,and I knew I didn't want to be holding on to a brand-new Irwin Bi-Metal when my hands hit the chuck,so I let go of the blade and got my hands out of the way as quick as I could. The blade hit the chuck,and shot it into the wall,sticking it almost 3/4 deep in the paneling behind the machine,thankfully. I'd have much rather have it stuck in the wall than my CHEST.
I know I shouldn't have been that close to the chuck to start with,but thought 3 inches out in front of the collet was plenty. I now do it a little different,combining methods.
I start by sticking about 4" out in front of the chuck,and using the blade,I just barely start to cut the tip from the bottom up,most of the time I get rid of 90% of the excess glue right then,reducing the amount of sanding needed. I also cut the tip back away from the ferrule about 1/16. I then move the tip back in the collet,and use the toolpost cutter until I get it almost flush. I pull it back out,and use the blade to trim it DNP then shape. I can use 400 from there and really clean up the ferrule,or if it's one of my few customers that properly chalks up and actually maintains their shafts,start with 600,then seal and polish.
In my experiene so far,the Ti-Nitride coated blades seem to stay sharp a little longer,but aren't as sharp out of the package as the typical Stanley.
The Stanley's are the most consistent as far as sharpness. I've tried the Irwin Bi-Metals twice,with mixed results. The first package of 5 was scalpel-sharp,and I got probably 15 tips out of each one,using them as a trimmer and shaper. The 2nd package wasn't anywhere close to as sharp as the first,and they were DONE after 2-3 tips each. Tommy D.
