You said that you wanted to learn or how to communicate with machinist. Decimal points are not requird but you can t go into a shop and say hey buddy can you make these parts for me. I kinda want this. If the spindle isn t turning there not making money and you come across as a time waster. You can draw a half inch hole how you want 1/2" .5, 5.005", 5.0005" The 5.0005"cost more. Your part is simple but i still don t know what you want exactly want. What if I make that radius for a two inch pipe and your pipe is three inches and doesn t conform for a good weld? Machinist love loose tolerances but hate talking about it for an hr. and then they don t want to pay for that hr. Grab a napkin even draw a rectangle with some lines. How long is it how wide, where are the holes and what size. Show radius and what pipe you want to mate to. Draw whatever you can from this.
Forgive me for stating the obvious, but I even posted pictures. How can you say you don't know what I want, when I said exactly what I was trying to do? 3.5" long, 1" wide, .375" thick, two half-inch holes, a bunch of grooves down one side, and a hollowed-out place on the other side. How hard can that be? Before I get to the point where I've taken money in hand to some shop somewhere, I'll be able to say with reasonable precise certainty exactly what the outside diameter of my pipe is, what the wall thickness is, and everything else. I'm just trying to understand the processes and the terminology so I can learn something about how this gets done.
I'm probably never going to become a machinist. Not because I think I can't, or because I don't think I'll like it, but because I want a degree in history when I go to college. Making things is just fun for me. Now, I understand that for lots of people here, it's money, and that's okay. If you think I'm wasting your time, I'll not bother you any more.
