One way I used one time on a 2-56 in model airplane engine mount. A broken tap it work using a brass welding rod and grit . Took some time but grind down tap.? Dave? Peter Way 12:55pm? ? I'm glad to hear about the nitric acid method, although it feels like a last resort.? ? To prevent tap breakage, I only go forward until the next flute, then back a little to break the chip. Alignment is very important, however you achieve that. On bigger taps you can feel a little resistance.I use a light cutting oil. If I don't have that, I use water. I hear kerosene is good for aluminum. For removing a small screw or tap, I try to cut a screwdriver slot with a Dremel cutoff wheel. I know it's not always practical. ?Reply Like More 1 - 13 of 13 previous page1next page ? Messages New Topic Chat M |
