That link will not open for me.
It works for me. Could it be a security setting on your computer that prevents it from opening?

Re: Making bushes

Regarding parting off, I backed out of this having had ordinary bronze crumple - a few minutes testing would have shown that leaded bronze is a different creature - next time. If you use a properly ground parting tool, I can't imagine a case where you wouldn't benefit by parting instead of sawing. ...

Re: Trailer w. trains stolen in Texas Saturday

JT’s trailer and equipment have been found safe. Don’t know any details just got the email. He did have LoJack or similar on his trailer. If you become privy to more information, please post accordingly, especially if the thief was identified. I've experienced being burglarized. I have no mercy for...

Re: Plating brass over chrome

The phenomenon is discussed in Hoke's book on refining. When gold is applied, or even placed in contact with silver, if is found to migrate. It literally diffuses in to the other element, eventually disappearing (as far as sight is concerned). It's still there, but has been absorbed. Gold plated cop...

Re: Threading without the end groove

Newer editions of Machinery's Handbook are actually less useful for manual machining than old ones. They started deleting some of what is considered obsolete data to make room for more CNC-related stuff so that the book wouldn't get to be a foot thick. Yep! I agree, although Patio (one of our reade...

Re: Plating brass over chrome

Strange as it may appear, gold readily migrates towards base metals, but that is prevented by nickel plating. For that reason, it is common in industry to nickel plate electrical components that are gold finished. I'm not suggesting that that is the reason Colt plated first with nickel, but it certa...

Re: Threading without the end groove

Lets start with the thread size, which is NOT in the national course series. If it was NC, it would be six threads/inch. That said, what you have is likely considered to be an N-3 (class three) thread. Pitch diameter for that particular thread would be 1.4188"/1.4251". Minor diameter, which is the s...

Re: MEK sources

In the sixties I lived in Milan and was flying model airplane. There was a shop in the center of town that sold, to a 15 years old, the ingredients to make the fuel: Castor Oil, Methanol, Nitromethane, Amil Nitrate, Ethyl Ether all of which can kill you. Yep! It was the same here in the US. As a yo...

Re: MEK sources

Indications are, the chief reason for making the bulk of the chemicals unavailable to the general public is due to an attempt to limit individuals from making explosives. Nitric acid is a good example. It is still available for commercial use, and at a price that boggles the mind. Even in small quan...

Re: Making bushes

Geez and no one mentioned soft jaws. That was the first thing that popped into my mind. They would have to be made so that they almost entirely covered the od to prevent distortion, but that is what they are good for. --earlgo I actually did, as a second operation for chamfering the bore once the b...

Re: KEK sources

I've edited your post to correct the heading (KEK was replaced with MEK). If that was the wrong thing to do, please indicate that here and I'll make the change back. I did it so those who might do a search would have the desired results. That said, I recently bought what HD likes to call a replaceme...
