Kelton Hollower Dig In
Hi all,I haven't posted here in a while, but I know this is where I
can get this question answered. I use the Kelton Hollower and love it. I have made some modifications. I had the bushings bored out to take the 3\4" bar from my Jamison unit as the small Kelton I have would only take a 5/8 bar. This really adds a lot of strenth to the system. I also use the teardop scraper from the Jamison and it works great for all I do. However, when I get to the last inch or so in the bottom of a hollow form, I get a dig in. I keep the cutter slightly below center and angled aroung 5 to 10 degrees. The other day I used the cutter on an open face natural faced vessel. I watched to see what happen's at the bottom. I got a dig. WHY? Should I raise the cutter? Change the angle? Heeeeelp....... I have just posted new work on my web site...take a look. Thanks for any help you might be able to give. http://www.maine-web.com/woodturning |
Hi Joaz
You can see and understand what happens if you would draw a circle, then draw a line horizontally at center, and now mark a point just above the center line and against the circle, think as this is the point of cutting, now if you get a slight pull on your tool that point will go down vertically, and if you would now draw that point of cutting just below the one you made earlier you will see that it is away from the circle, now do the same circle and line and now draw that point (the point of cutting) just below the horizontal line and against the circle , now if you would get a slight pull on your cutting or scraping tool it would go down vertically and if you would now draw that point of cutting vertically below the last one you will see that now you are into the catch or dig mode, you are in the wood and going deeper. So the rule is: for inside cutting or scraping, tool at or above center : for outside cutting or scraping, tool at or below center Hope this is some help Have fun and take care Leo Van Der Loo joaz wrote: Hi all,I haven't posted here in a while, but I know this is where I can get this question answered.
