I am relatively new to woodturning and I could use some pointers on a couple of items.
I'm starting a new project (not to resale) for a couple of clients/friends and I'll need to glue up the blanks, 4'' x 4'' x 4'' per cup. Should I be worried about any grain direction issues while gluing up the 8/4 (or larger) material? There will be liquids in the finished piece, so I'll need as "watertight" of a joint as possible (I know water and wood don't work well together). It's more of a keepsake than anything else, with an occasional toast of alcohol from time to time.
To that extent, I've been told maple and cherry are the best species to use for a project like this. Does this sound right, or does anyone have any other recommendations for species that will look good and hold up to a food-safe durable finish? I've been told to stay away from oily woods (teak, olivewood, etc.), but I would like to use a species that "pops" a little more than hard maple/cherry. Maybe a curly or figured maple? It's most important the species is durable though. I'm told for a project like this, the best options are species with small-medium pores, diffuse-porous, and higher Janka & dried weight levels. It's hard to find something that fits those qualities at 8/4. I'm trying to minimize my glue lines, max 1-2 (unless this doesn't make a difference?).
Finally (if you're still reading), I am planning on finishing the insides with a wipe-on food-safe poly and the outsides with Odie's Oil. Any thoughts here? I know finishes are tricky and there's never going to be just one correct answer.
I look forward to hearing peoples' thoughts on all of this. There are a lot of questions/topics I touched on and I don't expect to get answers on all of them. But, if anyone has some advice on just 1 or 2 of the items, that would be greatly appreciated! I'll take all the information, pointers, suggestions, tips, guidance, instructions, or anything else as I can!
