Re: Coal dust bricks again

Interesting story. Could you separate the different metals from each other too? Yes, which is precisely what a refiner does. The resulting metal (from the furnace process) was similar in appearance to pale yellow brass. It was comprised, primarily, of silver, as the waste material in question came ...

Re: A Real Dirty Job

Wow! A tough way to achieve the desired end! Kudos for your creativity. Sure makes me appreciate my DoAll. I've also accomplished that task using my little Wells A7 horizontal band saw. That was of necessity, as I didn't own the DoAll at the time. The Wells A7 has adjustable ball bearing guides, and...

Re: Good practice question

No-one has mentioned follower rests, yet. I don't have one so I can't say yay or nay. I'm in the opposite situation: I have a follower, but no steady. So maybe in a situation like the one that prompted my question, a follower could be sufficient? Not really an alternate solution, as a follower does...

Re: Coal dust bricks again

QUESTION: Considering the cost of coal and the finite limit on life, which is more important, pasting pieces of coal dust together or making something new and worthwhile in your shop? Only asking. I think one's location and needs would determine the worthiness of reclaiming coal dust for use. While...

Re: all-thread studs for clamping

Unfortunately Fastenal now only sells business to business. Hmmm. I wonder if that's true in all areas? I haven't stopped by the local Fastenal in a while, but they've offered mixed service in the past, from not selling small quantities to over pricing, even charging shipping on items forwarded wit...

Re: Whistles

Would it be OK to copy and post that article from LS? I ask because because of the magazine being out of print for a while. BC Considering copyright, it likely wouldn't be acceptable. However, there are exceptions to the "rule". Perhaps one of the attorney's who frequent this board could offer a pr...

Re: HEIGHT Gauge question

The problem with splitting is that you don't really "know" what you're seeing, so the resulting calculated dimension may or may not represent the actual measurement. If you're working to tenths, it simply wouldn't be adequate. This is much the same as using a caliper, be it vernier, digital or dial,...

Re: grey iron

The additive is known as Glomag. It's magnesium and silicon. It causes the included carbon to precipitate as spheres instead of flakes. The gray iron must be low in sulfur in order for the inoculant to work. Ductile iron is far superior to gray iron, as it has extreme ductility as compared to gray. ...

My pleasure. I hope it helps you understand how tight tolerance inspection was once accomplished.

Re: HEIGHT Gauge question

Correct. If you're not familiar with the Pla-Chek, it's really the easiest way to do so, however. Think of it as a supermicrometer standing vertical. It has rings @ 1" intervals and is calibrated in tenths. You pick up a given feature on the part you're inspecting, setting the indicator at 0, and th...

Re: HEIGHT Gauge question

Is it possible to get measurements better than .001" tolerance? Strictly my opinion. Resolution is the term I'd use. Depends on the nature of your setup, and what you're inspecting, assuming that's how you're using the height gauge. For layout? Not a chance. For inspection purposes, if you use a go...

Good to hear you're ok, Dick. Network news has shown some pretty heavy damage.
