Greetings all; I just about have my g33wrapper.ngc working again, but I see several problems because I used fixed values for some of the variables, derived by successive approximations. Not good for versatility should I want to carve some of Andy's threads. :)
I want it to be universal, but I am not there yet. Those I need to sort, but first I need to fix in my mind things like which edge of the threading tool should be doing the cutting, leading edge always or trailing edge always? Trailing edge seems to work but did seem to cause a medium frequency judder as the cut got deeper. This I think may be in the spindle bearings & I need to remove a thou worth of shim in the front bearing as its running 10F cooler than the rear ATM after 10 minutes at around 1600 rpm. Worst case rise is about 35F over room. I am told that is expected from bronze bearings. And I'd imagine some of it is not metal to metal drag, but oil viscosity in that thin a film. So the 10W non-detergent may get replaced by 5w-20 synthetic. ======== It sure works wonders in the small yard engines and standby generators about the place, allowing them to be started by pull string on the first pull in zero F weather. The oil consumption has also been cut by very noticeable amounts, that 12.5hp in my rider is burning very little compared to the fixed 20w with 5w30 in it, and it starts instantly even in snowplow weather. On the 20w I'd be adding a pint about every other time I mowed. On the 5w30, in 2 years, I still have half the makeup quart I bought left. Is there any reason I should not use modern oils in this lathe? Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
