That's enormous! Freight might cost a few dollars for that
I am posting an image outlining my proposed Input/output requirements. I would love to hear from someone if I am going the wrong direction here. I have never attempted to design/control this many in/outs before. My old router has one output... a relay for the router.
So, I am open to any suggestions. As a matter of fact, my design of the controls for this thing will be based on the input I receive on this forum.

I would just say Wow, a real piece of engineering. keep posting.
as per request, more pics of the glorious casting
My machinist and I are both ecstatic about how this pattern came out... first time go, from a couple of novices... Could not be happier.
Pattern is approx 60 inches by 19 inches, by 7.375 inches height. Casting was 5/8" shorter, due to shrinkage.
These pics were taken today at the cast iron party: a celebration of getting more acquainted with this ancient technology.
Hope the pics are enjoyed. This is truly the coolest thing I have ever done with Rhino3d and my CNC. Go Rhinocam!!!
Cheers,
Rob
Damn that's nice! Better than most of the Chinese castings that come on tools these days! No need to cover it with 1/4" of bondo and paint like they do... Out of curiosity, how much $ does it take to cast a 1-off of something like that if you supply a completed pattern? Do they charge by the pound, by time, both, or...? I can only imagine the stuff you'll make on that new beast of a machine!
I think they charge a little of both. Although we supplied the pattern, there was considerable form-work to accomplish. Several 2 x 12's, metal weldments to facilitate hoisting and flipping the boxes, and some decent carpentry to make the core-box for the area beneath boss for the lead-screw (vise).
The casting weighed 475lbs. Material consistency is excellent, based on later machining (for testing) of the risers and flue. Total cost for their iron and services was $1850.
This is higher than we were quoted, but the quote was based on a very rudimentary drawing, with less material. In the pursuit of the most excellent band saw ever, this cost is acceptable to us, and we would do it again.
Again, this is not my band saw. My machinist is spending 10X what he would have to to buy a band saw of similar capacity. There are bronze guide-rails for the blade tightening assy, among other rather exotic features. I realize this may seem silly to spend so much on this item. I think he would argue that this is functional, mechanical art.

Hi Rob,
Really nice casting - way nicer than any I have done. Out of curiosity, how did you find this place? I have some items I may want cast in iron in the future.

My friend found them in the yellow pages... Clarksville Foundry. They have been in business since before the Civil War. I may be speculating here, but I would think that most larger towns/small cities have a foundry. Those man-hole covers have to come from somewhere!

Another pic just came in from Taiwan... Thanks Kirk!

i dont think your going to need those cement pads you have.Originally Posted by spoiledbrat
It's the global era. Some pics from New York :-)
My pleasure. I will get more after paint. As for the man hole covers..... wow I had no clue.
