Introduction: Cooking Oil Level

Picture of Cooking Oil Level

feeling a bit off axis? build this level out of a couple of nuts and bolts, clear tubing, and olive oil.

Step 1: Parts Layout

Picture of Parts Layout

+ a few inches of clear plastic tubing (3/8" inner diam., 1/2" outer diam. ~2.50$/roll @ homedepot)
+ two matching nuts and bolts that fit snuggly into clear plastic tubing. (7/16" worked well)
+ string
+ drill bit big enough to send string through (1/4" is fine)
+ a few nails
+ hot glue
+ olive oil (or any liquid, really; i chose olive oil for it's colour and viscosity)
+ a piece of wood that you feel is level (and pretty).



Step 2: Assembly, Pt. 1

Place a nut onto the bolt. put some hot glue on the end of the bolt and put the bolt into the plastic tube. The bolts must be able to seal liquid. a snug fit + hot glue should do the trick.

Step 3: Assembly, Pt. 2

put some oil into the glass tube. You want to add just a litle less oil than will completely fill the tube after the next bolt goes in. Eyeball well, and then pay attention to how deep you add the second bolt. The excess air in the tube will be the air bubble that makes the level useful.

Step 4: Assembly, Pt. 3

put a nut on the second bolt, put hot glue on the tip, and insert into the tube. now, the leveling mechanism should be complete, ready to be attached to the base.

Step 5: Assembly, Pt. 4

get your level piece of wood and eyeball where-abouts you want to attach the leveler. drill holes in the wood so that you can loop string through to tie the bolts down. A nail next to each set of string-holes will be helpful, too.

Step 6: Assembly, Pt. 5

Picture of Assembly, Pt. 5

tie down the bolts by sending string through the holes and around the wood + bolt. Then wrap the string around the nail, kind of like a guitar string around a guitar peg. Make sure the the bolts are level - a flat face of the end of the bolt and the nut on each bolt should both be in contact with the wood. If both bolts have flat sides touching the base plate, and the same buts and bolts were used, then the device should be right about level.

The string goes through holes in the mid scetion of the wood in order not to disturb the flatness of the bottom of the wood base plate.

As you are tying, the air bubble in the tube should be roughly centered in the tube. If this isn't the case, check that the bolts are the same and level. Another common problem is that the tubing is bent, and thus not level. Use a smaller gap between the bolts to encourage a flatter tube. Also, check another level, because maybe the table you are working on isn't level.

When your done, use a permanent marker and mark on the tube where the edges of the air bubble should be when the device is level, for reference.

Good work!

sharlston (author)2010-01-24

really good idea id neaten it up though maybe use  cork as a plug and glue it instead of the screwthread id cut a large hole in a chunk of wod and insert it into it so its like a real one

This is REALLY cool!

Naeem Iftikhar (author)2008-02-16

Its good for in emergency situation at least you have a solution. GOOOOOOOd

Cool as something to do for DIY, but I would think the bolts and tubing and everything would cost as much or more than just buying a level. Around here they almost give them away.

In England we call these spirit levels. They use spirit because if they used water it would freeze in winter and would not work. Plus the correct way to test, even a bought spirit level is accurate is to do this. Place unit on surface. Note bubble place in vile. Twist unit end for end (Turn 180*) If it is still in the same place it is accurate. If not, dump it.

hmm, you want an even curve on the tube section so that the highest point is in the middle. i think typical commercial units have about a 2-4 degree bend to them. it looks like you used the pre-curve of the vinyl tube, but perhaps better would be to use a naturally uncurved tube and set the curve using the two bolts. by putting a spacer under the hex-nuts you could adjust the angle of the bolts on the wood stick, and thereby the angle of the tube as it leaves the bolts.

or just put a pin/nail under the center of the tube Either way, as long as theres a curve of some description you should calibrate it flat, mark either end of the bubble with a sharpie and then proceed And maybe use some hardwood, it is less likely to warp over time
