Hi guys, here’s my finished angle gauge. The LED in the top is red and the one side comes off to change the batteries. Additionally the top threaded contact point is adjustable; it work’s great.
Also, I thought that I’d mention that I have a gear motor on the way from Florida to make a powered actuator/lead screw for the computer stand angle adjustor; it’ll now be powered so the angle of the platen will be able to be adjusted with a push button pendant from the front! That will be cool won’t it….I found this great surplus electronic and more store and you need to go there and see it:

Cool place….

Could you explain how it works & what angles you can determine? Maybe I’m an imbecile, but I don’t see how it works.

What it is it?
What does it do?

My guess is that you use it to put your table saw blade at a 90 deg. angle .
Please explain .

The angle gauge is for squaring a saw blade or other appropriate tool by adjusting the threaded contact points up against a steel square on a flat surface. When they are both equidistant they contact the square and light the red LED then when you set it on the saw table and move the blade to square, once it is square both contacts once again will be connected and the red LED lighted indicating that the saw blade is perpendicular to the table at 90 degrees. If you want to do other angles you would clamp it to something of that known angle and it would complete the circuit when your blade or otherwise is also at that angle with both contact points touching the blade.
There is a two battery holder inside for power and one could use a subminiature panel lamp in place of an LED if they desired. I placed small coil springs between the brass washers to which I have the leads soldered and the nuts on the ends to both assure good contact and conduction and also to prevent the adjustable point from freely rotating thereby coming out of adjustment.

Now I understand how it works. Thanks for the info.

Do you have pictures of the internals???

I wasn’t thinking but I’ll take some photos and post them tomorrow. Does the gauge make sense to you all? If it doesn’t tell me and I’ll write more about it.

great build metro

i can see how one for square
and maybe some others
with one long and one short screw
would work for angles
like 45 and 22 1/2 degrees

thanks for the help

Your tool is just too cool and oh so simple. :-)

Gotta’ make one.

Thanks for sharing. – Len

I see how it all works now. Thanks for the additional information & drawings. It seems like a simple and eloqent shop aide. The key is that it is easy to make and use. K,I,S,S, is just the sort of project I can handle!!!

Again, thanks for the info.

I worked with a guy that bought a level with an angle gauge.It worked great….only thing was he still had to cut and check the fit just like i did with tried and true ancient techniques….
My angle gauge was 3 bucks at the swap meet….his was 100+.
The next weekend he stayed home and amired that gauge….i spent 80 bucks and went fishin and had enough for a couple beers too

Doesn’t the table surface then need to be perfectly level with the earth? This one is between three and six bucks if you play your cards right…this is what I do for recreation; I design, engineer, and then I build, it’s what I’ve always done since my first building set just going on three years of age; either Tinker Toys or an Erector set in addition to an electric train set….
Obviously I don’t do photography well.

It won’t work on teflon coated saw blades. I made one years ago. It worked, but thought it was too basic to patent. The theory has been around a long time. It is used in metalworking in various forms, but thanks anyway for posting. Obviously there are some who don’t understand.

My saw blades are made out of steel and only steel with the exception of satellite tooth tips and don’t have any halogenated hydro-carbon materials on them. I design and build because I am a 62 years of age little boy and it’s fun and prevents me from developing dementia complicated by boredom. Building and showing the little gauge was one, for my convenience; two, because a lot of the guys on this site are enthusiastic craftsmen/hobbyists; and three, there never was intended to be a marketing scheme or ploy; it’s just plain fun as opposed to vicarious activities like spending money to view idiots chasing and throwing a ball in some adolescent field game. I’ve always been a creator and participant as opposed to a spectator.
