Ed, I found the HSM issue and was able to determine that the gears link the 2 spindle housings so that they rotate equally when the cutter "opening" is adjusted. Chin
I see now the cutters are freewheeling, I initially thought the gears might "time" the cutters to keep the crosshatch consistent. Slaphead

The swiveling angle of the knurl (wheel) holders doesn't need to be geared, IMHO that's overkill. All you need is a single reference line that's located on the same point on each of the angled holders. Then you would scribe lines on the body those rotate on, marking at 0º, 30º, 45º and 60º. This allows you to make true diamond patterns of any angle, square, or straight knurls.

Pretty slick Russ! Just curious, do they remaining pieces of alu. left on the chuck just go to the scrap bin?

Yes sir, however, the batch of 400 of these (just slightly different) I am going to try to do three pieces in one handling to reduce the scrap.

Later,
Russ

Russ,

How do you remove the stub left over from the parting off operation?
Nice video, by the way. Thumbsup

Hi Ed,

Thank you!

Typically we just clip it off with some wire cutters and then touch it up on a belt sander.

If the part requires a really good finish we then hit it on the scotch brite belt sander afterwards and it polishes it up super nice!

The total time from clipping to polish is about 15 seconds.

Best Regards,
Russ
