Introduction: Make Portable Digital Height Gage. Made in TechShop Detroit.

Background:

Nowadays, digital calipers are very inexpensive and part of makers daily tools when designing things. It is very portable as well.

Ocassionally, we would need to use a digital height gage. I recently created 2 hemispherical parts out of ShopBot. I intend to glue them together to produce a 3" sphere. I cut them off the bandsaw with a slight extra thickness to sand off before gluing them together. But I need a precise measurement of 1.5" height on each.

Here's a list of inexpensive digital calipers.

Step 1: Creating the Base

* The base is formed by stacking 3 pcs 3" diameter disk.

* Each disk is slotted 3mm to the center. I used 3mm because this make the caliper lip snuck tightly to the base.

* Note that the caliper lip need to be slightly below the top surface.

* I put a 3" diameter acrylic on top.

Step 2: Instruction

* For many, the use of the digital height gage need no further instruction if you have used a caliper before.

* Pull the upper lip all the way to the base.

* Turn power on and/or zero it.

* Select unit: mm or inch.

* Raise the upper lip.

* Position part and slide down upper lip and read the height.

Step 3: Safety Precaution.

* As with any instrument, safety is number one priority.

* Use this setup for short and transient use. Disassemble when not in use.

* Avoid having children nearby.

* Note the pointed hard object standing up.

* Note too that the pointed hole depth measurement sliding part (when upper lip is raised) could be sticking out.

* Best is to disassemble this right after use.

* The author is not liable for any injury to anyone.

ENJOY and BE SAFE AT ALL TIMES.
