Those rods are really nice but why are the oil grooves so deep? Why aren't they just in the cap since the rod takes most of the load.

Nice. What machine is used to cut the oil groove?

I like the paint dot method of numbering as opposed the cold chisel hash marks that are seen so often. Nice looking bearings btw!

The grooves are deep, at about .040 to hold oil. It doesn't do any good at all just to mark the Babbitt to make it look like an oil groove, you have to have depth to hold, and carry oil to do any good.

If there wasn't any grooving in the cap, you would get excessive wear.

The rods that you are looking at always have the X groove complete, or it wouldn't be an X groove.

Most grooving in rods go clear to its shell backing, even more so, main shells.

Jack, we use a Storm-Valcan grooving machine.

Herm: How about a picture of said grooving machine? Thanks, Dan.

Excellent workmanship, using shims, proper grooves for oil retention, mirror finish. read posts on another site where a single groove in center of connecting rod was machined, engine ran for a short time before burning up the babbitt. I imagine the thrust face on the center main is left a little heavy to be machined later to adjust crankshaft thrust clearance?

Yup, Steve, we leave .050 thousandths, to much on either side to make sure that what ever the crank width is, there would be enough, when align bored.

Thanks,

Herm.
