Awesome Slide Chart
This engineering slide chart is a must-have tool for any mechanical designer. We’ve been using a smaller version for years and it has been an incredibly useful tool, unfortunately it was only in inches. One of our designers recently found this one that has metric values, as well. It also has about a dozen other things that our old one didn’t have:
- Screw Selector & Tapping
- Drill Sizes
- Pipe Sizes and Tapping
- Surface Texture/Surface Finish (N Grade)
- Prefixes
- Rulers
- Hardness/Tensile Conversion
- Amperage Conversion
- Beam Deflection Equations
- 1° and 1/4° Draft Angle (inches/mm)
- Statistics Equations
- Thermoplastic Properties
- Sheet Metal and Wires Sizes
- Sheet Metal Bending Allowances
- Carbon and Alloy Steel Numbering System
- Actual Pipe Size Comparison
- Units Conversions
- Constant Acceleration Equations
- Shore Durometer
- Fractions to Inches to mm
- SinØ, CosØ, & TanØ Equations
- General Engineering Equations
- Moment of Inertia Formulas
- Geometric Tolerances
- Welding Symbols
- Densities of Common Materials
The slide chart provides values in both English and Metric units, all on the same card. The old one in our office was made by “Alvin” (called the Screw Data Selector) and is still available if you search the internet, but the Engineering Slide Chart (made by Great Innovations) is an even more useful version of Alvin’s Data Selector. This is really one of those tools that EVERY mechanical designer should have on his desk every single day. And for $30, there’s no excuse not to get one.
