[CAUT] Hammer boring charts

[Jim Busby]

Yes. Was this from Newton? Anyway, It’s a nice reference to have.

Thanks.

All,

Several years ago I got an excellent hammer boring chart on line. I think it was on CAUT. Well, I lost it, and while I pretty much know how to bore it was nice to see all these “factory specs” and see where they went with their boring angles, rake, etc. Sometimes it simply helps me verify my own work, sometimes I change a bit towards what the factory does. (Usually not)

Does anyone have that chart? (Was it Newton? I can’t remember, and nothing pops up on a search)

Thanks.
