Hi everyone,
I finally had some time in the shed today, and got to play with my new (secondhand) lathe and new supernova2 chuck.
Obviously it makes sense to start with a lump of jarrah burl. What else would I remind myself what turning is like with?!
I screwed the blank to small faceplate, and turned the outside. This went really well, and I even pulled the skew out to remind myself just how easy it is to catch! All sanded and finished with shelawax, time for the inside.
In the supernova 2 manual, it says to cut the hole in the base with a scew scraper (15 degrees). I don't have one, so just guessed using a parting tool and round nosed scraper. I have a feeling that maybe I should get what it says!
I switched the bowl around and started in the inside. A nice catch on some of the burl and bowl went flying across the room. Glad I was wearing my face mask, as it just bounced off.
On inspection, the base sheared off, I think because the angle was wrong and all the pressure was on one point. That and I should have turned a tennon, as the burl was very curly!
Anyway - I want to find the right scraper for this, as I want to make quite a few bowls - but I can't find a 15 degree skew scraper anywhere. Do I just get a square nose and recut it to be 15?
Thanks for any suggestions!
Matt
