Topic tags/keywords: coffee cup coffee cup

I got this crazy idea to make a wooden coffee cup and ACTUALLY USE IT FOR HOT COFFEE.

Did an Internet search but didn’t come up with much.

Any ideas on what wood to use? (Something non-toxic that doesn’t move much)

How to seal it? (Mineral Oil, Epoxy?)

If I don’t seal it, will it …
  1. leak/seep
  2. make the coffee taste bad
  3. kill me over time

Mountain men, colonial settlers and other frontiersmen used wooden cups. They were called “noggins”

I made a few of these and sold them to re-enacters. I used acrylic tile sealer on the inside only. I was told that it was a “food safe” finish. I also made leather bottles and lined them inside with the acrylic tile sealer or for those who were purists with brewers pitch.

I think Woodcraft has a stainless steel insert for mugs.

I make something like this as a hobby. Generally I take the insert out of a travel mug and clad it in wood.

I’ve been considering doing this too and have personally settled on getting a small metal insert for it. But that’s mostly so I can be lazy and take the insert out occasionally to dishwasher-blast it.

DO NOT USE EPOXY! My Dad used epoxy to fix a tea cup and after it cured for quite a while decided to drink from that cup. It tasted horrible and almost instantly made him nauseous. I suppose there are different kinds of epoxy but I’ll never try it ;-)

These are actually pretty easy, there is some math involved to get that near perfect continuous look to the wood on the outside, nothing too complex, mostly it’s basic x,y,z geometry.
The mugs I work with are pretty cheap too, they are stainless steel inside and sell for 2 for $6 at Big Lots. Pretty much any travel mug that has a lid is a candidate for doing this, if you are like me and don’t want to depend upon an adhesive to hold em together I suggest doing a metal band, copper, brass, or bronze, avoid steel as it rusts pretty well.

Here’s the math part
you need to find the circumference of the top and bottom of the mug, you do so with the following
circumference = 2 x pi x radius
then you figure out the width of the slats you are going to be working with and divide that by the radius at the top. You can fiddle around with dimensions a bit, but usually I round up and use a bench sander to get them finished into the final width.
so, for the mugs above, lets say that I’m working with a mug that has a diameter of 3.25 inches, that means that the circumference is going to be approx 10.21 inches. (diameter x pi = circumference).
so if the slats I’m working with are .75 inches I come out with about 13.6 slats, so round up to 14 and I’ll be using the sander to get everything neat and tight.
same math type stuff for the bottom, so the diameter of the bottom is about 2.75 inches, so the circumference is about 8.63 inches. From here you can figure out the taper you need to get everything nice and neat.
The bevel for the slats is really easy 360/2(number of slats) = angle of the bevel for each side.
So 360/ 2×14 = about 12.9 degrees, so I round up to 13.

That’s pretty much all the math side of this done.
Normally I’ll fudge the numbers a bit further so I have a void between the insert and the wood and will backfill that with an expanding foam.
You will likely need to bevel the top and bottom of the slats to get them to fit neatly under the bands you are working with (unless you are using an adhesive).

To get everything tight I use hose clamps, I’ve got several of different sizes and they are by far the best thing I’ve found for getting these to fit together nicely.

I’m planning on doing a few more this weekend if all goes well. If there is enough interest I’ll be happy to journal and post the process.

Leon, I toyed with this same thing last year. I do segmented turning and wanted a cup I could really use. Thought of all the usual suspects. Acrylics, epoxy etc. Then made a cup that holds regular 8 oz styrafoam cup. Just taper the inside of your wooden cup to hold the styrafoam snuggly . I leave the bottom of my wooden cups open so you can push the old styrafoam out with no problem. You could probably do the same with any hot drink cup.
