And being as how that expansion joint is the weakest link in those I-beams.....

Yea, it's not like we don't have any idea WHERE to focus an inspection.

I'm sorry to hear that Dave will no longer be with us. I'll miss his insights on multiple topics. He was one of those all-around fix-it guys. Like his signature said: "Big Dave, former Millwright, Electrician, Environmental conditioning, and back yard Fixxit guy. Now retired, pursuing boats, trains,...

Sounds like they are blaming it on corrosion, but one has to question the inspections & inspectors.

Corrosion.

One of the reasons we have inspections.

No personal experience, but I know that they make brake lines for cars out of PTFE, but they are covered in braided stainless steel to protect them.

The Mianus River bridge on 95 in Greenwich fell in because it had pin and hanger construction and was neglected for a long time. The bridge over the harbor in Bridgeport (yes, where they made the machines) had the same construction at the time and you could just see the rust all around the pins. To ...

I had an older fella give me some,advice many years ago. He said, “It doesn’t matter what what the value is. It only matters what somebody is willing to pay for it.” Ebay is over run with sellers who do not seem to understand this simple fact. That is the definition of "value", what someone is will...

I doubt he'll get that for it. If a used one in pristine condition is worth $6,000 (about four times what a typical used one in good condition would be), then the premium for "unused" is $5,000 That would mean that either: A: someone is willing to pay a pile of cash for a museum piece and never use ...

We have a local supplier, Logan Steel (in Meriden and Torrington, CT), that has the "bargain barn" where the drops are located. When I say "drops", I don't mean pieces 6" long - they can be several feet. I need a 3-1/4" diameter steel bar for an overarm, and they have it cheaper than anyone and I do...

This looks like a perfect job for soft jaws. Set your compound for the degree taper you want; cut one side then reverse the piece in the chuck and turn the other taper. This way you only have to set the tool post once. You will have to "hog out the center portion before doing the tapers. I think I ...

Best of luck to you for a speedy recovery, Big Dave.

I think there is a better way to brush. Even a small wheel wire brush, mounted to a bearing arbor. Angled +-45 * the brush will spin and remove more chips from the wheels.

Veddy interesting!
