HI Speed Tool Steel To Mild Steel..

admin

Had to make a plunge tool for the face of a big 'ol piece of steel in the lathe..Here is the pieces..Simple enough..Grind before welding then clamp and weld..(Yeah I fixed the vice)Top of the bit..Little stitch on the bottom..The hook for digging on the end..More on why next.....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:Gotta turn out major metal in this just for lightening only..Leave a 2.5 Dia center and then drill and tap 1-8" 2" deep after..Gouging near the center hub..Looking for a groove like this..For a regular carbide insert tool to do it's damage..Turn to the outside edge while taking off 1/4" at a time..Next!.....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:What did you use as filler?  Do you ever have problems with it cracking out on the HAZ when using er-70s?Common sense in an uncommon degree is what the world calls wisdom.

Reply:So you're saying the plunge tool was the HS tool steel, and the big ole piece is mild steel? City of L.A.

Reply:Your beads look really nice. I probably should have made my screen name booger welds. On the stitch do you use short "U" type movements to get it to look like that?______________Clarke 95  Lincoln 135  Lincoln AC 225 ---------I'm an idiot, please talk slowing and simple.

Reply:Did you pre-heat the high speed? It probably busted because welding made it brittle. Unless you pre and post heat. I would have silver soldered it. Most if not all cutters are silver soldered.
