Angle checker

Following on from the recent Forum discussion on the aircraft grade aluminium right angle checker manufactured in Ohio, I thought I would post my interpretation of the device made in my garage workshop in Hatfield Peverel.
In the true spirit of emulation I used ebonised lemon wood from an ancient recipe passed down through generations of craftsmen. The wood was cut on my micro adjustable sliding sled (post will follow later) and was hand shaped with my laser guided block plane. A gold plated vintage spark plug knurled nut was used to secure the components after numerous coats of shellac sanding sealer and Australian carnuba wax had been applied by hand. The third picture shows the component parts of the device. In total the cost was less than £1.00 or $1.50 in old money.

I hope that fellow LJs will be tempted to create their own versions of this device for the edification of all of us.

Thanks for sharing. Looks very nice.

The pivot screw looks to be at the center of the longest piece. Is that correct?

Also, if you close the sides, are the overlapping points the same length?

Great work and pleased to see there are still masters of the craft still alive today.

Not sure if I could stretch the budget that far though

I saw the same forum. $60 was a little high for two sticks with a pivot in the middle. I thought about building one, too, but you were a lot quicker. Good job. Since it’s a 2000 year old idea, it’ll probably work just fine without aircraft aluminum.

Thanks for the inspiration. I copied/posted one similar to your’s but not quite as good!

But mine is cheaper!

TrBlu – The long stick has a pivot hole exactly in the centre. The pivot hole in the short stick coincides with that in the long stick. When the instrument is closed the two pointy bits coincide. Hope this helps. Feel free to create your own version.

TruBlu – do it this way:

  1. First make the short arm, complete with pointy end and hole for the pivot bolt.
  2. Cut the long arm more than double the length of the short arm and drill the pivot hole in the centre of the arm – some error can still be tolerated at this point.
  3. Align the short arm along the long arm in one direction, then use the short arm to mark the shape of the long arm.
  4. Align the short arm along the long arm in the opposite direction, then use the short arm to mark the shape of the long arm.
  5. Shape both ends of the long arm using the short arm to check that the ends of the long arm are accurate.

Easy as that.

Need one of those laser guided planes…question: did you go with an air cooled model?

Air cooled with a touch screen display! You can really notice the difference.

Nice job. Pythagoras would be proud and impressed! I’m sure he is happy that some one is still using his theorem ;-))

Ok – with a wooden block plane, do I have to get it to start photosynthesis again to power the touch screen? My 3’ x 4’ solar panels are too cumbersome to carry and I don’t have a power jack for them to connect to the block plane.

But I’ll try this out! I mean, I’d RATHER spend a bajillion bucks on an aluminum one. But it’s so much more trouble!

1 pound, men that is still too expensive, I am in Mexico 1 pound is like 23 pesos, there go my tacos… :-)

Great job! But it is not red, it has to be red to be worth a lot… :-)
