    Help identify this tap?

    After scrutinizing the relieved threads on the end of the tap in the Tool Making book and comparing them with yours, I agree that what you have there is for cast iron stitching.

    Out of curiosity, when was that?

    Help identify this tap?

    Ok. These taps were apparently used in the mass-production of threaded nuts. The explanantion given in the book is not very technical but apparently the nuts were threaded and then manually removed from the shank of the tap where they collected.

    Help identify this tap?

    That helped! There's info on the internet about the Reece Company, which specialized in taps and dies for the pipe industry. After merging with the Wells Tool Company, Reece was eventiually absorbed into the Cleveland Twist Drill Company. The tap in question was manufactured not only by Reece...

    Very interesting tap. So, who's the manufacturer and what's the location?

    Yes, they were cast in a grayish-white metalium (aluminum or magnesium?) with the name Boucher on the side. Here's a video of a Polly Wog being test run on the bench. If the video is stopped at around 2:28, you'll see the cylinder castings clearly. BOUCHER POLLY WOG LAST TEST ON STEAM - YouTube

    Stop knocking yourself out...RDG Tools is "Myford." RDG bought the rights to Myford when they went belly up. Check out the Internet, and the advert pages of MEW or ME and you should see several sources for used Myford spares (gears, etc.) that ship all over. Hope this helps.

    Rescuing a Stuart Triple Expansion engine

    I might be able to help, as I have that size thread tooling and a (limited) supply of 11/64" (.176" a/f) steel hex stock to produce a small batch of 4-36 screws. If .176" across the flats will work for you, let me know the length and quantity required. Drillrod (nyc)

    Hello from NYC

    Hello Ray, Thank you for welcoming me to the forum. I don't recall posting on the Mamod forum, though I'm sure I have lurked there a few times in search of info on small, alcohol fired, chicken feed burners for marine style boilers. Are you into marine steam?
