My dad is a machinist buff. He loves spending hours upon hours out in the garage milling, playing on his lathe, and welding. I noticed he has a few posters with measurements and graphs used for referencing various information. It's pretty common for guys to have these charts as there is a lot of math involved and it's easier to just look it up rather than calculating it every time.
WELLS.
I hopped on Photoshop and came up with this [below] using various graphs that I had seen in his shop. I decided against getting it framed, fearing of hurting my mom's feelings. I'll have to figure out something else for my dad's gift. But I thought I out to share with SOMEBODY.
