Re: Holes in cast iron
Like others have said, if it doesn't affect the usage of the vice why bother? Ralph On Sat, Feb 24, 2024 at 1:34?PM mike <mooseheadc@...> wrote:

Re: Holes in cast iron
Get a junk vice from a garage sale or Goodwill for practice, to see how it will turn out for whatever method you chose. Don't practice on the item you want to keep. For the mig, you can get Silicon Bronze wire, and use argon or CO2 gas. Yes, it will still leave a golden area like the brazing rod, but if you haven't done brazing rod?before, that's one more new skill to master. Now that isn't a bad thing, but unless you're retired, you may not want to devote time to that. I have done both, and I feel the mig with the bronze wire was a lot faster to get good results with.

They're not an exact color match, but, they're gray instead of brass colored. They're also trickier to use than classic bronze rods. |

Bill,
I honestly don¡¯t know what they are worth. (I saw some for sale on the internet and thought the prices were insane. That would lead me to think he might not be selling anything anymore. Lautard still has his website up but I don¡¯t know if he is still around. He was born in 1946 and that would place him at 78. Dick |

But use a very large vertical boring mill and 10 feet from dial indicator.? Works great On tail stock I never need a that a digital or dial for drill bits but but used large drills.? Dave? GadgetBuilder 7:03am? ? Rather than a dial caliper I used a 2" long travel indicator as seen here: https://gadgetbuilder.com/TailFlag.jpg This uses a plastic flag on the tailstock and a magnetic base to hold the indicator on the tailstock. Easily removed when not needed. Large dial is easy on old eyes ;-) |
Re: Can You Use a Dial Caliper as ag Non-Digital "DRO?" (was "Re: LittleMachines DROs and dials")
Yes you can the dial type can be adjusted to zero.? I had one on a Bridgeport mill. I work great.

Not a bad idea - batteries run out to fast.? ? ?But being visually impaired, I'll stick with the digital type.
I have not done so, but it's no different from using a digital caliper as the starting point. Cut off the unwanted parts and make a mount. -- Lone Tree, Colorado? ?USA |

JB Weld is about 4,700 psi Deacon is about 8,700psi high in cost also use on machine tool bed repair.? In hobby work JB Weld is lot easier to use over welding and low cost.? The Devcon is great it can be molded in place without having to machine the bedways and dovetails. It cheaper to use JB Weld and may not see any different.? Dave? |

If cast iron jaws or location the typical the cast is about 25,000psi.? If steel it could go a lot high to 100,000 psi a different problem and fluxcore/mig is a good option.? Brazing is can also be good some rods are 67,000 psi that rod I use for repairs. The down side is you can see the color of brass.? If restoring fof some else the may want the same or very close color . If cast iron this a real pain the fine righ color of rod. The cast iron welding is very higher skill need.? Dave? chrisser Feb 22? ? I inherited a nice little used milling vise from my Dad. It's been sitting on a shelf for a bit waiting for me to clean it up and put it to use. There's a couple spots where it looks like someone missed with a drill and drilled slightly into the tops of the jaws |
