Thread: What tool is this #2.

Antique nose picker. :confused:

I forget the name but it allows the transferral of a height from one point to another.
i.e. stand it on a router table, use it to measure the height that a bit sticks through the table, swing the arm out of the way, change bits, swing the arm back to reset the height.

Sound plausable? :confused:

G'day Bleeding Thumb

The rod that has the ball on the end, does the other end look the same and does it have a small hole going thru from one end to the other. If it does I would say that it is homemade and used for someting like what Clinton1 says.
The reason why ask what the rod looks like is because it looks like a pushrod out of car engine

Good onya Clinton. It is a Surface Gauge though sometimes called a scribing block.

Set rule upright against angle plate on surface table, set scriber point to required measurement and scribe object to be marked.

Scriber can also fitted in smaller hole where post is fitted or indeed replaced with a finger type test indicator.

The holes in Base are for dowel pins that can be knocked down below base and used to allow base to slide along a parallel edge.

Some also have a Vee machined down the centre of bottom of base for use on cylinderical work.

That should put that one to bed

When do i get my shavings?

If both knobs on the base allow adjustment of the uprights' angle (the knurled for coarse set, thumbscrew for fine tweaking) then I have to agree with Clinton.

It may not be what 'twas designed for, but it's how I'd use it...

Congratulations Dennis,
You have nailed it. It does indeed have a v shaped groove under the base plate although as for the description of a surface gauges use - I don't know what in the world your talking about.
Would you be so kind as to say that again in a fashion that a mentally challenged chap like myself could understand.
Thanks
Tony
PS shavings are in the mail

Tony,

You Asked the least I can do is reply.

Apologie's that it is so mentally challenging, you have no idea how mentally challenging it was for me to do without a spell checker!

Surface table, usually made from Granite or Cast iron, come in various sizes 3'x5' largest I have used to 12 "x 10". Top surface exceedingly flat. Usually (in the past) used in inspection rooms in the :eek: engineering industry to check components for measurements and tolerances.

Angle Plate, (you do have a problem) 2 surfaces at 90°. All sizes, I use 10" long 8" deep 3/4" thick. (That's a good word) Each leg of plate slotted for attachment of whatever. Perhaps I should have put in 90°

Scriber I know that if you try really hard you can do it.

Rule upright see above (then again just for you vertical)

Set rule upright against angle plate on surface table, set scriber point to required measurement and scribe object to be marked. A method of transfering one known measurement eg rule to something other than a rule. Sometimes referred to as Marking out.

Just realised doing it again . if above does not help I will complete the confusion. I'd lke my din.din's now

I would have settled for saw dust on that one Having said that I hope you have already sent chips

Best regards,
Dennis

I used to use one of them 45 years ago checking patterns for accuracy in the foundry I was a pattern inspector in. More modern types now use a dial gauge.

put "height gauge" into Google Images and take a look.
Basically it transfers a height from one point to another.

Of course, I am probably wrong!

As others have said, it's a surface gauge or scribing block. In my days at high school, students who did metalwork usually made one of these in 3rd year.

Thanks for the explanation Dennis.
It sounds like it does the same thing as a infared scanner and CAD program but cheaper and easier to use

Did what you said Clinton found this.

<BIG>Surface Gauge</BIG>
A surface gauge is a handy little tool for scribing layout lines on a workpiece, or for transferring measurements from a rule to a workpiece. It consists of a case-hardened and flat ground steel base and an adjustable vertical arm that holds a sharp steel scribe. A fine adjustment screw is provided for setting the height very accurately. Usually they come with both a short and a long vertical arm. They can be purchased for around $15 in the usual sale flyers.
Some have ground and hardened pins (visible in the photo on the right end of the base) that can be pressed down so that they exend below the base. These are used to run the gauge along the finished edge of a workpiece to scribe a line at a specified distance from the edge.
The top of the vertical arm is usually turned into a small sphere above an recessed neck. When not in use, the sharp tip of the curved arm of the scriber is tucked into this recess so that you don't jab yourself with the point.


Sorry Dennis for some reason this description has been dumbed down enough that even I can uderstand. Must be the pictures
