Looking real good now Dave, you'll soon be there. You are doing the right thing by waiting for a new tap, too many get broken off down holes by people thinking they will last forever. If you have drilled the right sized hole, then it should cut fairly easily, any sign of it going tight after the fwds/bkwds motion, throw it and get a new one. John |

Good point John. I did the same with my BA taps and dies until the 8ba literally wouldn't cut anything! So got some soba ones for christmas from Chronos I think it was. Having said that, the 10ba tap didn't want to know on the 1/6" stainless I had though. Nick |

Just finished plug tapping the 6off 6BA threads, in the displacer cylinder. The new, German made, HSS tap, "purred" as it did it's job...... Seems there's no substitute for quality! :thumbup: David D |
| NickG:
David, I can testify that having had 2 BMWs and a Mini Cooper S, in my experience German made stuff does tend to purr! Someone at work always used to say buy cheap buy twice and that motto has turned out to be correct on a few occasions - but I still don't learn my lesson! Nick |

Hi David, I started buying my tools when I was about six, and figured out very soon, cheap tools cost more than good ones, always spend you money on the tools you will use often, with the greatest care for quality, and only ever buy a cheap tool if it is a one off job, and it's not likely the tool will break on its first job. I have taps and dies I bought from men who retired from the tool and die trade forty and more years ago, which are still sharp and cut well, and I have a few taps which I bought new which I never got a first hole done with, and have saved only because the shank may be used to grind into a cutter some day. I will say German tools tend to be good, but every country has tool and die makers who make and need the finest tools, so they can be had domestically, it's just a matter of knowing what quality looks like. I try to always buy new taps in sets of three, taper, plug and bottoming, because I will always need all three if I don't, and because cheap taps don't come in anything but taper, so the sets are so far, always good quality. Spend extra money if buying cutting tools for stainless, but you will get you money's worth, even if you spend the extra to use on aluminum or cast iron, getting a lifetime of use from them. On the other note, your engine is looking very good, and like it is getting very close to being a finished runner, and almost ready for video. I'm really looking forward to seeing it run right now. :headbang: :poke: mad jack |
