    Antique tapered tap ID, please.

    A friend dropped off a box of antique taps. He's downsizing and finally giving up the goods:). Amongst oddities like adjustable taps and long taps with 1/2" square drive were these tang driven tapered taps: Most are 26 tpi, some 28, some 17, most of the small ones are 32. No maker's mark...

    Using David Brown adjustable floating reamers - best practice?

    Acquired a box of these, with a cabinet of replacement blades at an auction years ago and never bothered to use them until a few weeks ago when I needed to ream a bushing bore. I got it to size, eventually, but the finish wasn't great. Amazingly stiff and predictable. I hear our friends across...

    Koch test indicator

    Given to me by a friend, who inherited it from a neighbor 30 years ago, who got it dog knows where. Anyone have any experience with these, Koch specifically? I have a couple others in this style, one Starrett, but none like this. Reads Koch Test Indicator, Nyack, NY. Pat July 17, 1906. The...

    Ratchetless Hardinge HV4N's. Why?

    I've been looking for one of these with a threaded nose and 9 out of ten I find FS are missing the ratcheting mechanism. How come? For example... How is this used effectively without a ratchet? Seems it's necessary for 2 positions or more - if it's only one position, then other workholders...

    Turret lathe tooling: What is this?

    Seen in a Wade hand turret lathe ad: What's it called, what does it do well?

    WTB: Older Royal 5C collets

    Looking to buy older Royal 5C collets that look like this: They were US made, once upon a time, and have longer, fatter, noses than more modern 5Cs. The distinguishing characteristic is the separate "band" near the external threads, which the newer...

    Maker of these bandsaw wheels?

    Picked these up at an auction, contents of the room etc. No identifying marks that I can see, previous owner passed away. 24" diameter, both rubber tired, no crown, no flanges. The wheel on the left is about 1.5" wide and has a straight keyed bore. The wheel on the right has a bore of...

    FS: Tubular 0-4 Mic and Lufkin planer gage

    Made by the Tubular Micrometer Co., St James, MN, merged with Scherr, became Scherr-Tumico, then S-T Industries, who sold the mic line to Sharpline.

    Bleach on Stainless Steel. What happens?

    I have some 304SS aerators that get clogged with bacteria occasionally and have been dousing them in bleach. Works great to kill bacteria and clear the pores, but also produces something that looks like rust. The intertubes says it's a nono, but as usual doesn't say why. Anyone here have...

    Cushman collets, India. Opinions?

    I'm looking for 22J collets to fill out my set, as always, and came across these folks, Toolsengg, who turn out to be in India and make Cushman collets, among other things. Prices for a new 22J collet are about a 1/3 of what Hardinge charges, so it's tempting, but it'd be a drag if one arrived...

    Filling small argon bottle from large?

    Yeah, I know, sounds dangerous, hi pressure and all that, but here's my problem. I maintain a 250 cu ft leased Argon bottle for my TIG welder. I also make vinegar and hard cider, both often stored in containers that aren't full. The best way to keep the liquid from oxidizing is to pump in...

    7" Pratt and Whitney bench lathe

    Mentioned in the Dalton thread, but thought that its own thread would get more views. It's in a scrap pile, about to disappear any day. I'll pick it up if anyone commits to a part or whole. I think there's a spare headstock in the pile, too. It's the lathe on the right.

    FS: Dalton lathe, Lot 4 SN#119

    Found this in the scrap pile of an old friend of mine, now passed. He'd started a toolmaker's apprenticeship at Pratt & Whitney and very quickly learned it wasn't for him. He was fond of his tools, though, but many of them passed through a fire or were stored in a barn for 40 years, with...

    OT? Delta Repulsion induction motor won't start on its own

    It's on a Delta drill press, started on its own last week, but doesn't now, just sits and hums. If I give the drive belt a fast enough yank, it'll come up to run speed and operate normally. It came from my Dad's estate, no idea how long it's been since it were apart, possibly not since being...

    OT: Good online source for leather boot laces?

    My goto general store has only Kiwi leather laces and there's nothing else with a prayer of having them within a 1/2hr of me. The Kiwis look good, but one lace broke 4 times in the last two days. New POS is what they are. I really like leather laces on these boots. They stay put and can last...
