    Drilling strategy

    Seems like the perfect opportunity to hire a firm that specializes in concrete scanning to locate the rebar. 2 hours worth of scanning and layout could save you hours of hammer drilling. Yes, your anchor layout may change but your rebar will remain intact. Be aware, core drilling isn't the...

    putting piers through existing patio slab

    My opinion still sides with core drilling. For several reasons, all mentioned above. Cleaner look when finished. Saw cutting won't get you all the way through the slab at the corners unless you cut past the corner. No 90° corners for potential future cracks to begin from. Etc. A 24" diameter...

    In search of 7/8-12 tpi threaded rod or stud

    Tried the potassium aluminum sulfate solution today. As stated earlier, I kept the solution and the whistle warm, 205°F in my lab oven, While I did see some effervescence, that was about all I got from 7 hours of soaking. After rinsing and cleaning, there was not much difference, all of the...

    Well, it's been a few weeks, and the machine shop finished drilling out the stud, so I thought I would provide an update. Machine shop called today and wanted me take a look at things to see how I wanted to proceed. They cut the stud short, mounted the whistle in the guide and seat mill, and...

    In search of 7/8-12 tpi threaded rod or stud

    Took the whistle bell to the automotive machine shop near me today. They feel that they can properly secure the whistle bell, weld a nut onto the stud, and get the stud out with some heat and a wrench. I'm not so confident. Plan B is to drill it out. Shop says they can make the stud if...

    Sorry for the confusion. This stud is for the whistle itself. . Nothing to do with a display stand. To clarify, the picture with the stud is the bottom of the whistle bell, inverted. When flipped over, that stud threads into the whistle bowl. Steam comes in from the inlet at the bottom of...

    Odd pitch . . For my very odd hobby of collecting railroad steam whistles. I am in process of disassembling a newly acquired whistle. . And have found that the stud that holds the whistle bell to the whistle bowl, has severely chowdered threads, to the point that replacement is the easiest...

    As stated, I am in search of 4" or more of 7/8-12tpi threaded rod or stud. Have searched the usual suspects on the googler, and have come up with nothing. Any suggestions before I hire this out and have it machined? Thanks in advance.
