I'd like to make a bowl or hemispere shaped depression in a piece of wood or maybe a piece of metal (aluminum or brass). I have never done this before.
Is a router bit the only way to go or is there a bit for a drill press (like the large hole bits for clock making) that I can get?
I do not do routing very well; so obviously I'd prefer a wood drill bit, but I'd like to know in any case. All replies gratefully acknolwedged.
Can you give me a general price range or point me to some urls/web sites?
Thanks,
Jeff
