   Are any of you here needing a gearbox in the near future, and if so how many?
   I am going to make myself one and as long as I'm at it might as well make a few more.

   Good idea. How much?

   Send us a proposed dwg Kevin.

   What dwg software are you using?

Paul you said all the cnc machines you know of are all up to their ears in work, is there that high of a demand for their work? I assume your talking about professional/production level machines. I looked them up after I saw that posting (i have some limited cnc experience) and while the home shop/Hobbie level sets ups were reasonable, I see why you said they have to work when I found the high end ones. Not any more expensive than a well set up 18 wheeler and trailer, but if someone were to get one, how hard is ot to get to the "up to the ears" work level? I drive a company owned truck (alot less headache) but had no issues getting plenty of work when I owned my own truck.

There are a lot of small machines on the hobby level but they are good for light work only.
They would be good for making small casting patterns out of high density foam I suspect.
Pretty much the same as a 3D printer but faster.

It is said that there is no replacement for a lot of cast iron in NC machines.
Rigidity is very important. Especially when machining steel.
I am no expert on this stuff. I did take a course in G code programing.

In theory there are programs that will convert a IGES drawing file from Solid
Works or Rhino and convert it to G code. People tell me they don't work that well
and the code still has to be tweaked.  Some people don't use those programs
at all and write the G code from the get go.

David on here knows a 1000 times more than I will ever know.
