Good Morning!!!! 67F @ 5:45AM. Sunny. High near 95F. Winds S at 5 to 10 mph.
I wouldn't recommend any kind of synthetic filler to close up a hole that wasn't supported from the back, Drew. It may look OK for a while, but eventually it'll crack and perhaps even fall out. If you can get your hands on a chunk of aluminum or copper at least an inch thick, you can hold that up against the back of the hole and weld over it. Try to keep the heat on the edge of the hole and let the metal slump onto the chunk, and avoid letting the arc play directly on the block of backing metal. You need to get your eyes close enough to the molten puddle to see what's going on in enough detail such that it's clear when the metal is liquid and when it's frozen in place. With any welding method, if there's a secret, that is it. If you think stick welding is difficult, wait 'till you try TIG. Instead of having just one thing to move around, now you have both torch and wire to worry about, and often as not you'll put the wire on the electrode instead of in the puddle. And you'll have to learn to feed that wire using just your thumb and fingers, with gloves on.:shocked: Perhaps you could find someone with a MIG outfit that knows how to use it, or even better go out and get one of your own!:stirthepot::laughing: After years of struggling with stick and a cheap TIG outfit, I finally bit the bullet and picked up one of these:
POWER MIG(R) 18 C MIG Welder Cry once and get it over with and start looking foward to using it when something breaks instead...
Found some more detailed pictures of that centerstand tang yesterday and decided that the shape on the one I'd made was too far off. It needed to be more of an oval in cross section, and the one I had was a rectangle with rounded corners. Figured I could get close by using a larger radius cutter and biasing it toward the long side of the rectangle, leaving something of a corner on the short side that can be rounded over on the belt sander. I'd just put a new blade on the bandsaw and it just zipped through a chunk of 1/2" plate and the rest was just time spent cranking handles on the mill. One small error to fix this morning, as one end should be necked down above where the tang gets welded to the stand, and I moved the cutter too far in one spot. This morning that'll get filled up with a few spots of MIG (Gas Metal Arc) weld and no one'll know the difference.:laughing:
Hang in there, gang. Friday's comin'!
