I just bought one of these speed/feed calculators for $9.00 . Looks like they might be convienant for some of us rookies. He says he has 9 of them when I bought mine.

I got one a while back. I've got to where I tend to just go by gut impression, but when things don't work, I pull out the card (or calculator) to see what I messed up.

YOD -

Thanks, indeed! One for me and one for my TechShop pal, Lloyd, who's always having to help beginners figure this stuff.

Boy, $9 seems a bit pricy. They probably gave them away to customers. I have several similar calculators for electronics and I got them free.

Basically it's just a set of tables in a compact form. You could make your own table with Excel.

There's probably some truth in Paul but I would have given $20 for the convenience! Based on that, I probably should go back and buy another!

edited to add: Don't bother looking. He must have sold them all. I went back for another in case the bicycle I ride from one end of my shop to the other gets a flat tire!

In a book I found a table that lists feed and speed for many different materials and many cutting tools. I copied and enlarges the table and put it in a plastic sheet protector and have copies on the walls by my lathe and mill. Ver convient when needed.

Asphalt, Concrete and now Speeds & Feeds.

Excellent addition to my high-tech calculators!

Thanks for the heads-up, Dog.
