I was given small sample of stained white teak. So I had to make something small to check this wood in action by making 2.5 inch tall 5 min hourglass. Picture 3 – 5 shows how i bored the center hole and mounting the glass to protect from braking by wood expansion and shrinkage

That is the most unusual hourglass i’ve ever seen. Very interesting and well done!

Very clever. Took a minute to figure out that you broke the disc then glued it back together, but I still haven’t figured out how you bored the center hole with lips at both ends.

Tomw, my guess is he used a router bit that fit inside the hole he bored, and then simply routed the inside circumference of the hole to make the lip on both sides. just need a bearing that allows the bit to have that 1/8 inch depth of cut.

Fun project Yuri. I think you were very clever to break the disk rather than making it oval by sawing it. You could of course also have jointed two pieces with a paper joint before drilling the hole to accomplish the same thing, but I think the broken edges glue joint will be more invisible the way you did it.

That’s a very unusual design. It looks good.

Thank you all. Breaking disk and gluing back leaves no mark at all, almost impossible to find the joint. 99% of the time wood breaks by the grain line.
