    Aluminum thread repair inserts

    I purchased a high temperature "thread locker and pipe sealant" through McMaster Carr to repair cast aluminum valve covers to avoid the cost of replacing them. The product is called Resbond 907TS Blue. The manufacturer's website is listed on the bottle is www.cotronics.com The temperature...

    vernier scale depth micrometer .0001" resolution...

    I'm working with two older machinists who insist on using depth micrometers WITHOUT a digital readout, and without a dial, so Vernier is all that's left as far as I know. The necessary measurement is part of the process to rebuild passenger rail car gear boxes on a commuter rail system, and...

    Is your blast cabinet a siphon style blaster or does it use a pressure vessel?

    drill press mobile base

    Thanks for the compliment. The purpose of not welding it was to give me the flexibility of breaking it down and using the components on other pieces of equipment.

    24" x 48" granite surface plate AND wtb

    This size doesn't seem to be too common, though it would be a good size to put in my shop and have it double as a work surface with a cover on it. I want the surface plate for scraping. Is there anything off about a plate of this size? I've tried to work with someone on Facebook in...

    tool bit grinding wheel

    I have a Baldor 500 tool bit grinder which I've used a few times. It has a green grinding wheel which is very soft. While it works well, it generates a LOT of dust. It's now time to dress the wheel, which is going to make a mess. Short of winning the lottery and purchasing a diamond grit...

    reversing switch on a single pole single phase electric motor?

    I have a single phase single pole motor originally wired with a black lead, a brown lead, and a green lead. Is anyone familiar with this color combination? There is no information anywhere on the motor or under the access plate on wiring it. Is there any way short of trial and error, which...

    recommended strategy to recondition an 18" x 4" knee mill table?

    Thanks for your input. It may not be a standard practice but do you know if a camelback can be used with feeler gauges to determine the extent of wear? Any idea where I would source a 30" or 36" long camelback that is ALREADY scraped?

    recommended strategy to recondition an 18" x 4" knee mill table?

    It's an early mill, an Elgin VM2, made in Chicago. It was advertised as a precision mill and I imagine accuracies were probably .001" or better. .001" would be fine for me, but use is limited due to the table wear.

    recommended strategy to recondition an 18" x 4" knee mill table?

    I have an antique Elgin knee mill with an 18" x 4" table. The top of the knee has the original scraping in an X pattern, presumably for oil; the bottom of the table does not have any scraping. As the table moves to the far right and far left it tightens up so much that using the table at the...

    Scraping cast steel?

    I have two machines, a lathe bed at 30" L and a milling machine table at 18" L, which are both badly worn. I'm looking at this as an alternative to a camelback, which I would have to purchase already scraped.

    Scraping cast steel?

    My goal is to get something which A, I can afford; B which I can move without a forklift; and C which can be scraped in the future. For the moment, I would have to use it as is.

    Scraping cast steel?

    Could be. My Elgin vertical mill was described in the original literature as "cast steel." It may just be a language issue.

    Scraping cast steel?

    Here's the pics. The third photos has a series of lines that appear to be about 1" machining marks along the long axis of the plate.

    Scraping cast steel?

    I'm looking at a surface plate advertised as "cast steel" made by the Challenger Machinery in Michigan. It's a vintage item which appears to have been machined at some point, but is unlikely to be super flat. Is there any such thing as scraping cast steel. Is it anything like scraping cast iron?
