My chart is about 2 by 3 feet and laminating it at the local UPS Store cost about $3. I make feed calculations for most projects. I have a mini-lathe and a small Unimat. I suggested to the Calculates Industries people that a built-in tachometer might be useful in a new design. My lathe and mill don't have a digital control of RPMs.
The chart is that coveted when I should laminate it? It's about 3 feet by 2 feet or so. I actually have a few of them. I used to use the printed hand reference ones. I will have to see who made the bigger ones originally.
I rarely ever bother with feed calculations, except for threading. Even then my manual and CNC lathe both have automated options for doing the task. Out of curiosity, how often do you need to make speed calculations?
I have one of those wall charts, too, Cabe. A while ago a company called "Small Parts" printed the chart and either sold it or gave it away. Sadly, they no longer offer it but people can find others. I recomment having a local office-supply store or Kinkos/Fedex or the UPS Store nearby laminate such charts. That way they resist oil, dirt, and swarf.
I have a machine shop too, and also enjoy the cutting oil, machine, metal smells. But, I am starting to wonder if these smells are degrading my lung capacity over time. Those aren't natural scents
Even though my smartphone could run apps that does everything the calculator can, I don't like to take my cell into the shop. Oil and debris gets everywhere, and my phone is the last place I want to see it. This calculator, I would feel more comfortable having in the shop. I already have several small calcs out there covered in grim. However, at $70-80 dollars for the Calc Pro, I may have to pass for now. If it was more like $20, I'd consider it.
My giant, and free, drill chart on the wall has everything needed from tapping. Can't beat that price.
I don't know if someone has created a Machinery's Handbook app. I love the paper version and refer to it often, The Machinist Calc Pro is quite a nice device. I'm still learning about many capabilities. The instruction manual includes many helpful examples. Happy Holidays.
Jon, this sounds like the perfect complement to Machinery's Handbook. I wonder if they have an app for that, though. I tend to use my laptop to view drawings and access the internet while doing projects. One has to be careful. I probably should get a ruggedized one. This might also be a good app for a tablet, or phone with a larger screen.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
