Hi Ben,
Nice mug.
With regard to the lining of your mug have you thought about spinning your own liner. You can see this being done on you tube video v=8OZ95yOTL5s
(I cant include the full link apparently)

Then you can custom design the lip to have an internal thread for a screw on lid and also create a a turned back lip that could have a thread chased into the back of it that the wooden outer could then be screwed to. You could then have to base as a screw on fit which would allow you to then insulate the gap between the liner and wooden outer with expanding foam that could then be trimmed once dried to remove the excess. The important thing about expanding foam of course is to remember that you only need a small amount to fill a fairly large area.

Ooh I like that video. I will have to try that sometime.
I don't think it would be suitable to do the inner lining though as that's stainless steel (well as far as I'm aware).
It's a bit harder than aluminium to shape.
Maybe in the future.

You could apply some heat to soften it up. There are some videos showing this technique

That's fine looking piece - have to ask, where did you source the mug liner from?

Great project and excellent segmenting!

The mug liner was a cheap mug from home bargains/wilkos/b&m kinda shop.
It had a crappy plastic outer which was removed.
It's cheaper to do it that way than buy the kit.
Kits are £10+, mug was £4

A quick update.

It's been over 3 months now since I made the mug.
Just thought I would share progress and lessons learnt.

The mug gets used everyday for work (mon-fri)
I wash it every night and dry straight away.
It was finished with acrylic lacquer and was not coated on the inside.
It was also epoxied all the way down.

Lessons learnt.... As suggested, an air gap was needed and has been done on subsequent mugs.
I get a slight cracking noise from time to time when filling with hot liquid.
I presume this is the epoxy.
I also have a hairline crack appearing between one of the joints.
This must be down to cold wood and hot inner expanding.

With all the above said, it's still going strong.
It's not loose or leaking. It still keeps drinks hot.

All mugs after this one have got an air gap and only bonded at the top.
This gives expansion space.

Although improvements have been made, it still makes me smile when I see it.
A wonderful array of colours.
