My buddy does a lot of stamping dies and fixtures by stacking up laser
cut plates. Anything he can section and do in CAD he'll cut on the
laser then bolt the section together. He's done some real large
stuff. Dies for cones four feet in diameter for instance.
The CNC plasma system are just the ticket for making custom chain
sprockets. Say you need a big reduction gear for your machine. Say a
ring roller. Just buy some roller chain and a small small cog for
the motor. Then cut a matching bull sprocket for the big end. You
could get a big reduction that way.
Look at the way the Robo-Grip pliers are made. A stack of tool steel
plates. I've seem many products that used to be made forgings now
made with such laminations. Pliers, crimpers, drop hitches and anchor
davits come to mind.
How about an anvil? Draw an anvil shape. Cut enough peices for the
required thickness. Bolt and grind. Braze on a tool steel strike
Problem is: with all these ideas, you're going to buying enough plate
that you're boss will be begging scraps from you!

=========One name for laminated style dies is the "continental process."
This appears to have been popularized in Europe just after WW2
because of the shortage of machinists, machines and large chunks

"All" that is required is a vertical band saw, a suitable blade
and a file. Considerable skill with both also appears necessary,
although this is not indicated nor included in the text, but most
likely would not be beyond the skill of an advanced/skilled
amateur or HSM.
This looks like an interesting process. Anyone using it or seen
it in use? Cost/time/durability of continental versus
In Moltrecht's short description he indicates that sharp corners
are not possible because of the need for turning the saw blade
and the need to use the slug as the punch. This would not seem
to be a limit with water jet or plasma. Any thoughts?

Depends on what machines you have. A heavy CNC VMC makes short work of
conventional dies. The expense ends up being in the CAD and the
bolster. If you have to heat treat the die then a solid die is
better. Durability has not been a problem with the dies I've seen. Of
course you have less control of surface finish.
The technique is used widely enough that the CAD system have routines
in them to section the sollid, calculate the draft and spit out the
complete set of stepped G codes.

Making some big pliers sound like a good idea. I really like the
anvil idea. At least two of us at work are wanting one of these. We
have so much scrap here they wouldn't miss it if they even cared. I
took 2000 lbs home a few months ago and that was about two months
Thanks for the ideas
How about leg weights for that flee market awning. Circles 4"
diameter. Leg hole in the center. Next to that a smaller hole for an
eye bolt. Eyebolt long enough for several plate. Insert leg into
stack. Tie awning crossbar to eyebolt.
Cutting table slats. Weightbench weights. Drill index. Collet
holders. Screwdriver rack.

Screwdriver rack and collet holders are two good ideas I can use. I
thought of using the marking feature to mark for some drill indexes,
to then manuall drill. One guy here wanted some horses cut out and I
found some line drawing and so I'm going to make some of these. I'm
making carts and shelves out of all the scrap here now.
