A bit depressed

admin

I stopped by the neighbor shop on my way home to take a pic of something I did a long time ago, now I'm depressed...This was done in '95 and belongs to a Williams & White shear.I had them place the worst edge out when they put it back together (if it's going to fail better know it now).Anyway the blades have never been flipped...You can't see it well here but there is some "scallop" in the red circle, spalling (black arrows), and I couldn't see it because of the lighting behind the shear but it looks bad at the yellow arrow in this pic.The owner wasn't there at the time but the foreman could clearly tell I was about to bawl. I looked at him and said "I did it that time, someone else will do it next time, or just get new blades and now would be a good time to think about it".MattOh, the parameters were material=water hard, build up was WeldMold 880 and the cap was H12 modified hot work tool steel. All welding was done below 350F at 1". Attached Images

Reply:Brings to mind something I did many years ago at my previous job. Just finished changing the blades on our 10' shear, set the gaps, stroke etc., an all day job. Bright and early next morning one of our regulars shows up with half a dozen panels of 4 x 4 x 3/16 woven wire mesh to cut in half. Yeah I know, not 'spose to cut round in a shear but we had been doing it all along with not a problem so we (I) proceeded to shear it, hauled out the cuts threw it in the back of his truck and away he went. Crap, it only took 5 minutes so I never even bothered with a work order. Hour or so later I started cutting up some 12ga for a load of stair pans I had to bend up and noticed odd marks along the cut edge, WTF. Just then the phone rings and it's the guy that runs the company that I just cut the mesh for, "any chance you can shear up some crusher screen for us, we got it cheap and are going to use it for reinforcing mesh on a garage floor". Then the light hit, the marks were nicks in the blade every 4", not impressed.....Mike

Reply:Yea, dad got a deal on 42,000lbs of 8'x10'x1/4 plate well turns out it was AR400.   Our 1/4" capacity Atlantic completely dead stalled when he brought the blade down.   thankfully no harm no foul other than we now had a yard with 42,000lbs of plate that was useless to us.    good thing he found a buyer in AZ that was going to make wear plates out of it and paid way more than he did for it.Vantage 500's LN-25's, VI-400's, cobramatics, Miller migs, synch 350 LX, Powcon inverters, XMT's, 250 Ton Acurrpress 12' brake, 1/4" 10' Atlantic shear,Koikie plasma table W/ esab plasmas. marvel & hyd-mech saws, pirrana & metal muncher punches.
Reply:Update, neighbor shop may flip blades this weekend. The owner seemed depressed so I said I think you'll be OK.He said it was not about the shear and showed me a letter from the EPA requesting reply by Jan 2010 that "he just received monday"??? It was in regard to the sandblasting operation and included reference to proper collection and disposal of hazardous materials.They have a 16,000 sq.ft. blast building that has been in operation since 1971. Do you suppose there might be some lead and silica around in the soil???Guess I should just shut up and be happy...Matt
