Expressing my ignorance here: I understand that using a phosphoric acid solution is a weaker version of Parkerizing and that the phosphorous is a required ingredient. Does hydrochloric acid do the same, or does it just clean off rust well, without depositing a protective coating?
In the Frankford Arsenal short-handled one and the long-handled contractor ones, the magnet is spring-loaded inside of an aluminum housing. Once you pick up metal, you hold it over a trash can or other receptacle, pull the handle to raise the magnet off of the bottom, and the screws/chips fall...
I went to my local office supply store and got a test print off of all the inexpensive laser printers. I found that all of the HP and all of the Canon ones worked (two years ago). I suggest doing the same. FYI, I had heard that color laser printers didn't work and asked forum folks if that was...
The contractor version has a longer handle so that you can stand straight up and sweep the floor. I have the Frankford Arsenal version that I bought to pick up stainless steel pins (boy is that a great system to clean dirty brass), but I use the contractor version in the shop to save my back.
It is unfortunate that doggy care has gotten so expensive that it is actually less expensive to give your dog away when you go on vacation and get another when you get back. HOWEVER, who can take that emotional roller coaster? The moral of the story is that dog owners need to find compatible dog...
This particular stone may be red, but I seriously doubt that it is a ruby stone. If it was, it would say so and cost more. Look at ruby sharpening stones on the Amazon site and Gesswein site. A FINE ruby stone will put a mirror finish on a pistol sear, which is where I first used them. They are...
try pinching the graver between thumb and forefinger. Watch any of Sam Alfano's introductions to his videos to see how he holds his graver. Also look at Brian Powley's grip during his session on inlaying gold and other topics at an earlier Engrave-In sponsored by Scott Pilkington.
By touching the rim of the turntable to turn it, instead of trying to turn the vise, it takes much less effort, gives greater control, and lets your arm and hand relax at a lower level. My left shoulder issues became nonexistent when I set up my turntable. ONE CAUTION: when you set up a...
I found a good discussion that covers copper, brass, and bronze. https://www.sequoia-brass-copper.com/blog/metal-alloy-comparison-guide/
The alloy makes a huge difference. I.e., one brass is not necessarily the same as another.
This makes so much sense it is scary. Great tip. Good use for the refrigerator magnet ads that come glued to telephone books, if you ever get a telephone book anymore.
Here is the Wikipedia page on hardness of ELEMENTS, so it doesn't have alloys in it, like brass and copper.

Notice that many of the tests have quite a range of values. I have seen some other charts of Moh's info that also had...
The thing that concerned me about this particular test was that copper, bronze, and brass all had the same rating. I am not sure that this is the case. Because the Moh's test is a scratch test, rather than an impact or penetration test, I can see them being very close, but I am not sure that...
I found the following discussion on the Mineral Society of America website. It explains a key difference between the Moh's hardness scale and Brinell and other scales typically used to determine hardness in metals. What it doesn't say is if all the scales give a similar relative result.
MOHS'...
I have a small belt sander that is mounted upside down in a wood clamp with a 400 grit wet/dry belt. I put a little baby oil or WD-40 on the belt when cleaning up practice plates. I hold them with either a positionable magnet (the kind with the on-off rotating switch) that I got from Woodcraft...
