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.

Step 1: Materials

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.

Step 2: Cut the Log

Cut your log in half to size you want.

Use hole saw to set ring sizes.

80 degree angle cuts with dremel bits.

Step 3: Top and Bottoms. Assemble

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.

Step 4: Lathe Idea?

Lathe out each segment at an angle.

Just cut rings to center stationary base ring.

PULL UP FOR YOUR CUP

Lathe out lid.

Hope this stimulates some idea's
