Wanted: Custom Cam

[Loftfan]

I have a customer I've designed a cam for. He thought he had a good deal on getting this cam ground, but apparently these guys substituted one of their grinds without even looking at my data. We're naturally not very pleased.

So, for you grinders out there, I have an easy job. I need a BBC standard fire, standard journal cam in 8620. I provide the follower lift data and angles from the dowel pin, you provide the part. How much would it run me? Feel free to PM if you want.

$400 for the master.
$439.58 for the cam.

If you want someone to grind it on a CNC Landis, try Bordeaux cams (910)655-9035
They grind other peoples designs all the time, so they should be able to help.

Mike, in the "Circle Track" article, it shows you making custom masters in two steps. First cutting the profile on Aluminum bar stock with a CNC machine, then using that to make the masters. Can you say more about that process.? Do you just enter lift points into the CNC program? How long does it take? (seems more than $400. of time)

We no longer do it that way.
We now just CNC machine the actual master.

I design the actual Valve lift curve, and using a program I wrote, I generate the actual Lifter Lift curve.
I then take the Lifter lift curve data, and input it in another program I wrote that works through the geometry of the Berco Cam Grinder to generate the tool path for the master.
