I'm thinking about slicing a big bar of W2 that I got from Aldo into strips.

I'll be getting some of them blanchard ground for my own use... I'm wondering if anyone else is interested, and if so, would you want rough-cut bar or PG bar?

3/16" ? 1/4" ? something else? The bars will be 1.5" wide.

thanks
 
1/4" x 1-1/2" x ~1 mile long would be great for me ;)

Seriously Patriq, 1/4 x 1-1/2 ?? Put me on your list for some too :thumbup:

And I can deal with the "rough-cut", saw cut finish, no problem.

What kind of lengths are we talking about and when is this going to happen ?


:cool:
 
I'm sure the cost will be brutal.

The knowns are:

-I have a 4" x 1.5" x 24" piece of HR W2 from Aldo, for $3 per lb. He said it was from Bethlehem steel (?). So the biggest a bar can be is x" x 1.5" x 24". Total quantity will depend on bar sizes; you do the math.

-I have arrangements with a WJ shop for $100 per hour of machine time.

-I have arrangements with a blanchard grinding shop for $60 per hour of machine time.


Unknowns are:

-WJ run-time/feedrate

-Blanchard grinding run-time

-Possibility of alternative cutting method (saw?)


If I do use a WJ, the cuts will likely be VERY rough with a taper.

The more I do, or the fewer sizes I make, the cheaper it will be, because the blanchard grinder has a huge capacity.

I figured I would go ahead and chop up this block to see how the prices work out.

I think Aldo has more.

Patriqg, I worked with, (not for) a shop several years back that had a vertical type bandsaw with a long table (lengthwise). Although we wouldn't need it in this case, the head had the ability to perform miter/angled cuts by tipping the head. It could "rip" a bar of steel lengthwise to amazingly precise, parallel dimensions. It would auto feed the bar into the blade and the pieces would come off the saw like a piece of wood cut on a table saw with a rip fence. For a saw, it produced a very good finish, and fast too !

Since I'll be forging this stock, I could easily get away with merely a saw cut only finish. Others requirements may be a bit different.
Just throwing that out there to maybe cut down on cost :o and also to give you some ideas.

David,

thanks for the info. I've heard that such saws are out there; I will certainly look into that before I do the WJ method.

The WJ has a 0.040"+ kerf, I'm sure a bandsaw will be less.
 
Instead of cutting it, why not just forge it into bars and then normalize/anneal?
