    IIRC the design should have the clutch engaging when the handle is about 30 deg down from horizontal. If this doesn't last after adjustment I'd have to say that you're going to have to get into the...

    That's sort of my last choice, but it may come to that.

    I'm beginning to think that this is the old SAE J500 serration, kind of hoping to find someone who'd broach one or two pieces, or at least...

    Identifying a 48 tooth spline/serration

    I'm working on a 1950 Kearney & Trecker Autometric Model B. I've restored the fine speed control that was deleted by a previous owner (likely for the variable speed pulley stuff) and am trying to...

    The danger from PCB exposure isn't in a one-shot exposure, it's in the long term exposure. Outside of industrial exposure the risk is minimal so long as you're not eating or drinking the PCBs.

    Sure, pop some pics my way. I have a fair number of PDQ VS toolholders in the common endmill shank sizes and a few Jacobs taper holders. I've got a couple of the R8 masters as well.

    I was really looking to trade, not to sell.



    Same drawtube but understand that the collet is closed by it's outer rim and not by the 5C taper.

    WTT D1-3 5C step collet closers

    I have a couple of 'spare' step chuck closers. The take the collets with the taper on the large diameter, so they apply better pressure than the ones trying to clamp 5" diameter part using the...

    I would expect that the decision to grind the carriage ways would depend much on the condition of the tailstock ways, this because you're going to have to depend on them for a travel surface for the...

    Best I can tell is't a Roto-Cone RC75 taking a 1922V belt or perhaps an RC-80 taking a 2322V belt. I found a companion pulley that looked right (it fit the turned-off portion of the oddball input...

    Scissor lift bearing identification

    I'm looking for the bearing in the images below - it's the pivot bearing on a scissor lift and I'm looking for the name of the bearing so I can find a source for several (I need at least 8 for a lift...

    There's a drain for the headstock on the left side of the headstock under the top cover (probably have to take top and bottom covers off to use it). The bearing reservoirs don't have separate drains...

    If I recall correctly the rapid is responsible for running the oil pump in the apron.

    T4 should be back with the transformers. IIRC it's the smallest one back in there.

    Not a lot of detail in the images, so kind of spitballing here. I can't think of too many machining processes that would leave that kind of mark at the bottom of a hole, mechanical processes would...

    I have a set of Starrett #240 pin vises that are not knurled immediately below the pin end that can easily be clamped on center in a collet. The 240A is supposed to be good down to .010"

    "Internal" might be an overstatement, "integral" might be closer? I don't have a modular or I'd peek at T4 and have a look.

    T4 is a constant voltage transformer. Likely the capacitor is internal to the transformer - it's there to provide resonance needed for the constant voltage function.

    Yeah, you're in about the only other machinery desert I've seen. New Mexico at least has (had) the national labs, but now all their machinery has been sold off except a little bit of stuff.

    If I'd known I could have picked one up last week in an auction, several D1-3 chucks in that one - looked like they'd found a kit of 10EE chucks. I think the 8" 4 jaw ended up going for $45 or so. ...
