Re: Holes in cast iron

 

Goot some India made milling vise components and found several big blowholes filled with cheap Bondo. Dug it all out, cleaned it up, and thought about how to best fill the holes. After some time considering all the alternatives I have concluded that an epoxy filled stick is probably my best alternative as the problem is cosmetic!? ?Bill in Boulder

It is for me to go top end repair.

Keep it simple?

In this case JB Weld is best for this job

I think people are blowing this out of proportion. The original poster seemed to be talking about small, cosmetic holes. For these, epoxy should be sufficient with no need for welding, brazing, etc.

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.

Like others have said, if it doesn't affect the usage of the vice why bother?

He has advertised the first edition back in print in a couple of recent issues of Home Shop Machinist, and has a link to the new printing of it at amazon?

There are some on amazon also.

There's "for sale" and then there's "sold".? ? Toss out the very high priced and very low priced.? ?The average of the rest may be considered the value.? ? Keeping in mine the condition also.

There are some color matching rods for brazing cast iron! 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.

Most time I do calcs when making the drawings.?
I also have chart on wall which works for most. Then calculator in the tool box and 25.4 to covert from monkey ?? marks to inch

only thing I can think of is that the dials are usually larger than the digital read heads & if ya want to do metric there's some math involved

I've drilled holes in several digital calipers , some were like cutting butter & some were like drilling rock .

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.?

Re: Can You Use a Dial Caliper as a Non-Digital "DRO?" (was "Re: LittleMachines DROs and dials")

 

I was happy with numbers on quill.
My SB had no marks.?
My mini lathe has both inch and monkey ? marks. Happy days.

On SB I used tape on drill bit for depth.?

Re: Can You Use a Dial Caliper as a Non-Digital "DRO?" (was "Re: LittleMachines DROs and dials")

 

I have dial indicator that has 3?" face.
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.

I like digital type all I need to do is press zero button to set start depth.
