so here we are in the shop, sitting in front of me are a number of log cut offs. Walnut, maple and oak. 6in to 14in dia.
as a novice bowl turner I am posed with the question of which is more right turning a bowl on the lathe as one would find a branch/log in the tree or trying to blank said log from the side and turing it there. Is it more difficult to turn my “log” from the direction of having the felled cut end attached to the face plate? tanks wooley

I’m not completely following your question but here is the basic of converting a log to a bowl.

Start with a length of log that is equal to or a little longer than your desired diameter of the bowl. Split that log in half. Make a circle the diameter of the desired bowl out of plywood. Nail that circle to the half log on the bark side. Use that circle as a guide and cut the log on a band saw. The bark side will, eventually be the top of the bowl.

I think the best way to proceed with the turning is to start by attaching the bark side to a chuck with the big screw that comes with every chuck. Bring the tail stock up to secure the blank and start by cleaning up the bottom and creating a stub that you can later use to hold the bottom into a chuck.

Note – If you tried to mount the wood in the lathe as one would find a branch/log in the tree you would have pith (the very center of the log) at the bottom of the bowl where it would probably fall out. You’ve got to “get the pith out”.

Ruch,
Thank you very much you have answered my questions exactly! I have recently gotten some log piieces, “as the would be found in the tree” from a friend of mine with a chainsaw. My greatest draw back thus far in my bowl turning education. (Closely followed by wanting and dreaming of the day I can buy a chuck to hold my work!!!!)
without having had the expierience as of yet on cutting blanks from my logs/branches (BUT WILL JUST AS SOON AS POSSABLE) would one have a more easier thyme of hollowing if he/she were to be cutting against the grain rather than with it through the pith?
Thanks wooley

A chuck is not essential. You can accomplish the same thing with a face plate. It’s just a little more work to set up. When using a faceplate, I like to also use a waste block. Once I have a flat surface on the stock, I glue a waste block to the stock and attach the face plate to the waste block. This way you avoid screw holes into the bowl. It’s usually not very hard to remove the waste block later. Use CA glue around the edge only.
