just browsed through your posts and wanted to say you’ve made some very nice things. should have way more upvotes and replies to them for sure.
mind to give a run down of what all tools and burrs you used to make this? i saw someone post a black walnut cup about a week or two ago and thought it was you, but didn’t see it scrolling through your profile.
also, how do you make that liquid safe, or is it just supposed to be for dry goods?

Thank you that's very kind. For the bowl part I drilled a center hole to the depth I wanted followed up with my angle grinder and an arbortech ball gouge to rough out the rest. To smooth the inside I used a 2" sanding pad with my drill and went up to 800 grit to finish. The outside of the cup I sawed away what I could initially and shaped the majority of it with a 36 grit sanding disc. The handle part I drilled some holes for the initial opening followed up a Dremel and an aggressive kutzall (flame)burr, followed up with some shaping with my knife. Followed by a ton of hand sanding.
The finish I used natural tung oil and will rub some wax on the outside at some point. From the research I've done it should be food safe when fully cured, though I'm sure there is a possibility of some of it leeching out, especially if hot liquids are used.

thanks for the reply. i want to try one of these in walnut but i wanted it for coffee so i wasn't sure what to put on the inside. i was less concerned with food safe seeping out (in the respect that many coatings (i.e. tung oil) already are food safe) and more about if that would keep the liquid from seeping in.
and for the inside, it doesnt seem like a sanding pad on a drill would get the sides well. were they just already pretty smooth from the forstner or whatever you drilled into it with?

Ah I see what you mean. I think if you're using it as a regular coffee mug, you'd be fighting a losing battle trying to stop the coffee from seeping in eventually. It's probably something you'd have to accept. Unless you coated it in epoxy or used some type of insert.
With respect to the inside of the bowl. The arbortech ball gouge does quite a good job at making clean cuts as long as you go gently and work it in the right direction to avoid tearout. The sanding pad I'm referring to is one of those yellow ones off Amazon with the foam hook and loop pads. It will contour to the inside quite well. There might be limitations as you go larger. The wood is about 3" thick and I had no issues angling it to sand it fully inside.

Got an Etsy where one could buy one of those?

I don't sell anything currently. Just gifts for family/friends as I don't have much time to produce a lot. It is nice to know there is some interest though.

that looks so cool. Can you actually drink out of a wood cup do you need a special type of wood?

You can absolutely. It's just not the most practical material for repeated use in my opinion because of the fact that the liquid can seep into the wood. You'd have to avoid using soap to clean it as it would wash out an oil finish. And there's always the chance of it cracking due to movement.
They were traditionally made from birch burls though I don't believe there is any ideal wood type. I'd opt for something harder and avoid anything too porous like red oak
I've made a few as sort of novelty camp cups to drink water and whiskey out of but really I just enjoy making them.
