Collapsible Wood Cup

While backpacking I always have a collapsilble cup with me. Decided to make my own, out of wood laying around.

This is a rough prototype 3" Radius, 1 5/8" High. Made with a dremel. The most fun was making dremel attachments using the dremel. This took a good 5hrs to finish. Also see my collapsible plastic glass instructable.

LAST STEP IS FOR THOSE WOODWORKERS WITH A LATHE. THIS COULD BE DONE MUCH FASTER AND WITH PRECISION. LOOK FOWARD TO SEEING SOME DONE WITH A LATHE.

Wood log. Dry and completely round

Dremel

Hole saw

Chisel

Sandpaper

Square

Putty

I use soda caps for cutting wheels

Using the dremel grinding attachment. I made router bits using 10D framing spikes.

Drilling bits/cutting bits. Using 6 penny finish nails.

Grinders using 3" #8 Drywall screws.

Cut your log in half to size you want.

Use hole saw to set ring sizes.

80 degree angle cuts with dremel bits.

Grinding the base and lid with dremel.

Ring segments had to be patched with putty due to knots and thin walls.

After finishing with a water based sealer. Glued smallest ring to base.

This one does not hold WATER. Has a flat side, knots and uneven walls due to my using dremel.

Lathe out each segment at an angle.

Just cut rings to center stationary base ring.
