Gimme Some Lip!!

admin

Hee Hee...strange title to a thread... Got a bunch of machine core "chucks" to rebuild.. most are just worn on the face so welding and re-machining are all thats needed..Except for one..this one needed a taller "lip" for the tubes that slide over them.."could you just weld it up and re-machine it?"NOthis is how you do it..heres the subject matter...heres the lip that needs a taller oneheres the "new edge"..1 1/4" X 3/16" X 38"longjust tacked to the topone must remember to champher the edge thats going twards face before you start so you have somewhere to fill in with weld..if not why do it?and you just heat and beat as you work your way around..when it comes out "even" (dont "pull" to one side or the other) thats nice...next post......zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Heres the front "lip" welded...Heres the rear (no machining required)and heres the "lip" machined square to the face..And there you have it..one thing though..i'm not sure what these "chucks" are made of but once you weld to it it gets really hard..not brittle .. just hard..(nothing a carbide insert cant handle  )later.... ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:you know , zap on one hand i like seeing the stuff you weld and on the other hand i hate it because i dont get to weld on stuff like thatgood jobChuckASME Pressure Vessel welder
Reply:if its a tool steel, wouldnt the weld have essentially heat treated those areas somewhat?

Reply:good point. i'm just begining to learn about all this stuff. associates in precision machine technology is my goal. and this kind of stuff comes up in my metalurgy class. i'll have to post up my vice from my manufacturing class when i finish it. tolerance = +/-.0002
Reply:i did told them to day we need to do some stainless or cu/ni thay said if you want to weld that stuff doit at homeChuckASME Pressure Vessel welder

Reply:your right, there is one fixed jaw, and one that slide(does what it wants).  No pics yet since it is at school unfinished. everything is back from heat treat (52-56 RC), its down to grinding into specs. so hopefully next week or two it will be done (one class a week)
Reply:start a new thread under pics asap  let us all see it from a new thread...you'll be a hit!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:Originally Posted by zapster.....one must remember to champher the edge thats going twards face before you start so you have somewhere to fill in with weld..if not why do it?...zap!
Reply:perhaps because the component your welding to is so large that when you welded it, the rest of it's mass sucked all that heat out faster than normal creating a hardened effect in the HAZ? Did you have to increase heat to maintain optimal puddle characteristics?

Reply:Nice work.
Reply:Lack of preheat is always a concern on thick sections no matter what the carbon content.Hopefully you won't have problems Zap.  I guess if you have been doing it before and the customer is happy then no need to change.
