Here's a nifty trick I used in the shop recently, perhaps someone can make use of it on their own projects.. We had some standoff "hat sections" to fabricate a couple weeks back, and needed multiple quantities.
One of the bends was to form a 1/2" flange, so the press brake was used with a 1" wide die...
Using some rare earth magnets placed on the back side of the lower die to act as a backstop.... much easier set up than fooling with the Diacro's built in backstop..
The bonus was it pulled the galvanized sheet metal in tightly toward the magnet, a self-loading if you will...
Some of the finished products...

Last night I welded in a patch panel. I had used black paint on everything, and couldn't see anything. Everything was black! All I could see was the puddle.
I'm thinking that if the patch panel was grey primer, against all black, it would have been much easier..

Rather than fight with a mirror and flashlight to try to see a casting number/part number or other small detail, reach down with the camera on your cell phone and take a picture of it.
Wonder how much clearance you have between the air cleaner (or other parts) with the hood closed, put a light on the engine compartment, set the cell phone camera where it can gets a view of the parts (and won't get crushed) and turn it on to record a video. Close the hood and then retrieve the phone and review the video.

If you’re in a situation where you are going to be trial fitting a radiator numerous times (and possibly building/modifying brackets to hold it in), a piece of thick cardboard over the core (held on with tape) will help prevent any unexpected damn-it moments. The box it’s shipped in is a good source for the cardboard. I learned this the hard way many years ago, fortunately it was back in the brass copper days so it was a relatively easy repair. I’ll admit I don’t do this very time, but I probably should.
I went a step further on my current project, as I didn’t want to remove the AC condenser and knew I would be putting the mockup motor in and out numerous times in a short engine compartment. I cut a cover to put over the radiator opening to protect the condenser. From a couple of the nicks I put in the cover it was probably a pretty good idea that I did.

Right now I'm doing rust repair at the bottom of the car, and I don't have a lift. That means sitting cross legged on the ground, with the car on jackstands. To keep the sparks off, I use cardboard. I'll sit on the edge, and draw it up over my knees, and tuck it up under my arms. Then the sparks just roll off and hit the ground. Note: don't rest your elbows on the cardboard, cause sparks will get your elbows..

Someone around here turned suggested stainless steel cut off wheels. I'm not sure it made the shop tips thread, so there you have it. Stainless steel cut off wheels will out perform standard discs so well, that I actually save money (and time) by paying the higher price..

Found it to be a good practice to do a compression test before and after adjusting valves, lower compression after is a sure bet you have adjusted a valve too tight.
Not claiming this one (saw it on the web) but it works; using a variation to the oil in tubing method to find TDC, using a combo fuel pressure/vacuume gauge connecting the gauge to your compression tester's plug adapter. Find compression stroke on #1, rotate by hand back and forth between vacuum and pressure readings to find center on the gauge.

You can feel the differance in pressure/vacume with ur pinkie in the plug hole more sensitive than most guages-----
After an engine build and the initial valve setting and verifying after warm up/heat cycle/retorque--------I use the valve adjustment ( well not "valve adjustment". but rather "valve gap checking" to determine if anything has changed and then maybe a compression/ leakdown to determine what/where to look farther--------sure beats picking up pieces

On another forum (a couple others here hang there as well) we've been having a discussion on fluorescent fixture ballast replacement. The problem has become that the old magnetic style has just about disappeared. Late last year one of my ballasts (8' fixture) died. I go to the big box hardware as well as local hardware stores and all they have are "electronic" ballasts. I call the tech lines of, I think it was GE, and check to see if those are a suitable replacement. In a word.....no! Seems you can't mix electronic and magnetic ballasts on the same circuit.........which means I'd have to replace all 9 fixtures/ballasts. A little online searching and I was able to buy some NOS magnetic ballasts on ebay so bought a few for "just in case". Looked at LED replacement lamps, but the prices were astronomical. Well, as often happens with emerging technologies, the prices have come down for the LEDs, and probably will some more over time. At the same time, folks have been doing what I did, and the availability of older magnetic ballasts is shrinking quickly.
So, if you get into a similar pickle, consider the LED replacements. They give off good light, run cooler, don't have the characteristic hum of a fluorescent, and use less energy. They do require a small wiring change to bypass the ballast, but only takes minutes. Here's a pretty cost effective supplier for now; http://www.amazon.com/WYZM-4-Pack-Do...46QX5E8WC5EBM8 As with many things the more you buy the lower the unit cost. It wouldn't surprise me if in, say 6 months, they'll be even lower. I may have outsmarted myself buying an extra supply of those magnetic ballasts!Your Uncle Bob, Senior Geezer Curmudgeon
It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

Bob My 4 foot fluorescent lights went recently in the garage, right around the time Costco was selling a 2 pk. of 4 foot led replacements for 39.99 complete with bulbs and fixtures( https://www.costco.com/4%E2%80%99-Li...100284402.html). The light output is awesome compared to the old fluorescents and no toxic bulbs to deal with! Also low power consumption. I imagine much more expensive for 8 footers."

I put that last entry on the wrong thread...
Anyway, one thing I keep re-learning is that, when doing patch panels, think ahead. Be sure to leave yourself enough room to complete the weld. Especially on an inner panel.
Something I've been experimenting with, is giving a patch panel extra crown, so that after shrinkage it will sit true to the mating contour. It works, but gauging how much extra crown the panel needs is tricky. It seems better to have a bit too much, as extra can be tapped down, but too little and you're in a bit of a pickle if you can't access the back side of the patch..

I like poster board for templating patch panels. It cuts easy with scissors, holds a bend, and it's cheap.
Recently I found myself out of poster board, and discovered aluminum foil works just as well. Be sure to put it back before the wife starts dinner!.

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
