Steel to Cast with mig repair
#1
We obtained some new (new to us) equipment at work. A shop closed down in the city and we got another drill press, a brake and shear. Well, while waiting for a manual on the brake and shear, I decided to start looking over the drill press. It is a clone to the Clausing we have now, a nice big machine. I noticed the hand crank for the table elevation handle was broke off. Most of it was there, when they loaded it they must have caught it on something, breaking off the lug that the handle is mounted to.
So, I decided to make a new lug and handle, and weld it on the cast iron crank that was remaining. Now, Ive read about mig welding cast etc....never tried it. I have only repaired cast with O/A brazing, with fair success, I think sometimes I over heat it and the braze dont want to stick, but usually do ok.
Now, I have another reason for wanting to use mig. I have a Johnson bandsaw Im working on at home and need to weld the gash in the table and I dont have my torches at my shop yet, still in storage. So I figure Ill give this a shot
Here are the photos: the lug welded on, then smoothed out with a flap wheel, then the handle I made thats threaded in the lug with a set screw on the back side of the lug, I used a bolt to make the screw and cut the slot in it with the shaper. It welded ok, had the wire speed up a little more than I should have, no pre/post heat, did peen it a little. Now, lets see if it holds lol...........
