We decided to make some steel calipers for Eric, as we are already dong the aluminum ones, and it turned out to be a fiasco!

My foundry guy decided to to use steel instead of a grade of iron that was hard-enable.

Didn't find out unit I got the bill from my machinist as about 3x what we thought it should be. Long story short, we have about 4 sets of calipers that are very nice. The only difference you will notice over factory is the hardware is 8mm not 7mm.

Looking to get $925 a set. Unfortunately, this still is selling at a loss.

Eric has built up one set, and has the spacers for the vented ones, so just looking to cut some losses as they do me no good setting on a shelf. I will post in classifieds, but wanted to put this up here to give a little back story. I have one built set now and can have Eric build vented / non vented sets to order.

These include the upgraded duro-anno pistons also!

Just a sidenote. . Six calipers were NOT gold cad originally. . they were silver. Might be a consideration for the next run. . What do these use for rebuild kits?
They look identical otherwise. . Nice effort on your part Mark. .

Here is my remaining NOS 6 Caliper. . definitely silver from the factory

Eric put them together, I do know the pistons are the duro anno, but as far as the guts go, Eric was generous enough to source the parts, I'm sure they are top notch. He has several sets un built, so if color is an issue it could be changed, just a matter of coat and time to do so.

Very pretty! The black oxide hardware will probably start rusting after the first rain or wash though.

Which foundry are these coming from? (I used to work in the cast iron industry.)

The fading is due to the slow breakdown of the plating, instead of the part rusting.

From: http://www.streetmachineclub.com/features/...int-it-plate-it

"Yellow cadmium plating (or yellow cad) is common on many production automobiles. Yellow cad is in a class of metal coatings known as “sacrificial coatings.” When exposed to the elements, these coatings are designed to sacrifice themselves in order to protect the underlying base metal. The bright yellow cad fades to silver then to a chalky white coating."

Whats the story on the alloy version? I was pondering going with the alloy ones because they're 4 pounds lighter.

These are steel not the aluminum ones.
However, Eric's generosity in building these is allowing for a price reduction. , $799 A SET!
THANKS ERIC!

And pretty much sold out. I bought one of the two last sets. As I said in my project thread, if you want the other set, better blow up Eric's phone!

The cast alloy calipers appear to be made from patterns matching the original calipers.

Shouldn't the patterns have been substantially enlarged (increased wall and rib thicknesses, etc) to account for use of the weaker alloy aluminum material?
