I recently constructed a Passive RF Field Strength Meter. I had an old uA analog meter in my junk-box which I used as the meter for the project. Now I needed a way to cut out the hole and drill the four connecting bolts to the cabinet. Normally if you buy a new analog meter a template is provided. Well AI is your answer.
I asked AI the following: " AI draw me a template for an analogue meter. The diameter is 45mm and it has 4 bolts to install the meter. The face of the meter is 50 mm x 50 mm"
Here is a technical layout template for your analog panel meter.
Template Dimensions & Specifications
Outer Panel Face: 50 mm × 50 mm square.
Main Center Cutout: 45 mm diameter circle.
Bolt Hole Configuration: Four symmetric holes at the corners.
Bolt Hole Clearance: 2.5 mm inset from the edges (45 mm × 45 mm bolt pattern grid center-to-center).
Recommended Hole Diameter: 3 mm (suitable for standard M2.5 or M3 mounting bolts).
Installation Instructions
Print to Scale: Ensure your printer settings are set to "Actual Size" or "100% Scale" (do not select "Fit to Page").
Verify Dimensions: Before cutting, use a caliper or ruler to verify that the outer square measures exactly 50 mm.
Center Punch: Mark the center point of the 45 mm circle and the four corner bolt holes using a center punch to prevent your drill bit from walking.
Cut the Main Bore: Use a 45 mm hole saw or a chassis punch to cut the main center clearance hole.
Drill Mounting Holes: Drill the four corner holes using a 3 mm or 3.2 mm drill bit for easy bolt alignment.
Finally: AI saved me a lot of time and hassle in providing me with this template. The template resulted in a great and neat fit into the cabinet.
