    Eames chair repair.

    I repaired the back support of a late 50's Eames DCW, done in matt ebonized ash veneer, a few years ago. As I recall the core veneers were soft poplar; it is a stressed-skin engineering construction, with the hardwood face veneer carrying a disproportionate share of flexure strength. I...

    B&S Ultra Precision Angle Blocks quality?

    Well this was MSC, not eBay. They do keep high list markups but there's always some big discount, so I wasn't overly suspicious. I couldn't imagine a major supplier like that sourcing counterfeit product over a name brand, so I'm leaning toward thinking B&S is now pure BS. Yes, I'll probably...

    B&S Ultra Precision Angle Blocks quality?

    I bought a set of Brown & Sharpe angle setup blocks, B&S/Tesa #599-921-17, when they went on sale at MSC last April. These are supposedly USA made and spec'd to a tenth per inch or 30". Yes there are import knockoffs from China or India for 1/5 the price, I am not interested. The B&S set was on...

    "Rust Converter" heat stability and toxicity

    Here's the reply from CRC Technical Services. The stuff will be coming off, of course. I'm a little embarrassed but also concerned; here is what I wrote back to them. Most of us from time to time find ourselves welding, cutting or grinding on some old hardware covered in mystery paint; I'm...

    "Rust Converter" heat stability and toxicity

    Thanks. The CRC product isn't simply phosphoric acid, here is the product page and here is the safety datasheet. It indeed includes chlorinated compounds, and they do really mean "phosgene" (the poison gas). The vise had apparently been left outside some decades, then de-rusted aggressively...

    "Rust Converter" heat stability and toxicity

    This may be the wrong sub-forum, but as the case at hand is an antique forged steel post vise... One original hard jaw insert was missing and the base metal was badly mangled from subsequent use and incompetent repair. I welded in a new bit of 4140, stress relieved and blended, then wire...

    Felo "INOX" screwdrivers "for stainless steel screws only" ??

    I'd have thought so, but I had a Pratt-Read set of SS drivers on the boat since the 90's and they seem to hold up just as well (only not rusty from salt air). For kicks I just tested some of that type with Tsubosan files, they're about Rc 50. These new Felo "inox" ones are Rc 55 which is...

    Felo "INOX" screwdrivers "for stainless steel screws only" ??

    I'm ok guys, verboten fastener contact shot me to a parallel universe but I made my way back (glad I held on; screwdrivers out of stock on alt spacetime amazon). BTW there's no firewall inside the event horizon. Best I can figure it's some patronizing nanny warning to a presumed ignorant worker...

    Felo "INOX" screwdrivers "for stainless steel screws only" ??

    This set came as a freebie from Travers last month, but they are not in their catalog. The box says (in many languages): " To be used on stainless steel screws and objects. Prevents corrosive abrasion and extraneous rust. Not to be used on non-stainless steel! " The Felo catalog (page 71)...

    Nomenclature/source, SCMCN-type holder to use 100* edges on CCMT insert?

    The Sandvik and Kennametal CCMT inserts in my box have full cut geometry and chip breakers on all 4 points; and the CCGT high positives for aluminum are precision ground all round. They must be allowing for some kind of use on those points, even if they don't sell a holder. As to "why," well...

    Nomenclature/source, SCMCN-type holder to use 100* edges on CCMT insert?

    That's it, thanks! Kennametal, Sandvik, Walter etc. don't show this style. Now, to find one; google looks to be fresh out, your reply was the top hit. Probably special order. Am I the only cheap b@stard obsessed with using the whole insert? (For ref. I'd be looking for Dorian p/n SCYCN08-3A...

    Nomenclature/source, SCMCN-type holder to use 100* edges on CCMT insert?

    Can anyone out there reference a proper ISO name and/or source for a neutral OD/chamfer turning holder to use the otherwise wasted obtuse (100*) point on CCMT inserts? The SCMCN found in catalogs seems to always use the acute (80*) point. I found comparable holders for negative geometry...

    Help ID toolmaking lathe cross slide?

    Indeed, if only the rest of the lathe would appear... Alas, I think this piece left its lathe and the owner's shop at least 60 years ago, and passed through 4 other sets of hands in 3 different states since. I found it bolted (seized, more like) to a custom angle plate and V-block made by my...

    Help ID toolmaking lathe cross slide?

    Wow yes, that looks like a match. I'd flipped thru varieties of Hardinge, Stark, Rivett etc. but didn't think of P&W. Handles, separate degree vernier, and descending extension on the cross endcap for a micrometer stop rod all look like a match. Also the two little knurled knobs on topslide...

    Help ID toolmaking lathe cross slide?

    More family shop cleanout. This was found "near" other items inherited from my great uncle, who had a small tool & die shop near Utica, NY until the mid-1950's. I've never seen a Cataract in person, but handle shape, T-slot etc. look superficially similar. Compound angle scale appears to have...

    what are these?

    Clearing out my dad's shop, as I was about to pitch these something in the back of my mind says I once knew what they went to... can anyone jog my memory? Slot is 3/8" wide, post is 7/16" diameter x 1-1/8" long. Looks like CI or forged, originally nickel plated. Thanks for any help.
