    WTB: 8x12 Cast Iron Surface Plate(s)

    Looking for a couple 8x12 cast iron surface plates with webbing and 3-point support. I'd like to scrape these flat using the 3-plate method (some people make puzzles in their free time, I'd like to refine my scraping technique instead). I've got one already; looking for the second and third...

    Source for FP3 Headstock Cover?

    Title says it all. I'm trying to find a source for a cover for ram of my FP3L to protect the gearing while the vertical head is retracted. I've been through Franz Singer's website and haven't found it (although was happy to notice replacement way covers are surprisngly reasonably priced). Is...

    Interesting Long-Travel Rivett Taper Attachment

    Someone recently posted a link to this Rivett 1020S up for gov auction (Rivett Model 1020S Lathe with Collets and Chucks - NOT TESTED - govdeals.com) and I noticed it has an unusually long travel taper attachment. Appears to be about double the length of my 1030F's. Presumably it can't do angles...

    Surface Grinding Inconel: Wheel Selection?

    I've got a repeat job to surface grind some Inconel 718 parts, taking .005-.020" off each. We're grinding because there are hundreds of holes intersecting the surface at odd angles and minimizing burrs is very important. Surface finish and flatness aren't super important; .001" over a 6" square...

    Help Choosing a Manual OD Grinder

    Looking for a manual cylindrical grinder for an upcoming prototype job. The job is described below, but I'm wondering if anyone can suggest grinders that are well suited for this (so far, all I've found are Myfords). I've never run an OD grinder (first article made by turning .0005" oversize...

    B&S Techmaster 818 Manuals/Crossfeed Only One Way?

    I have a Brown and Sharpe Techmaster 818 grinder where the hydraulic cross feed only works in one direction (wheel towards operator). The PLC is getting signal from the relevant buttons and the spool valve controlling the crossfeed cylinder seems to work since it's operating normally in the one...

    Bringing Home an FP3L

    Been pretty dissatisfied with all the Bridgeports I've run, so I've decided to try out a Deckel: I'm a little ashamed to move such a clean machine into my filthy shop, but it'll at least remain covered when not in use. I expect to have a number of questions but will of course use search...

    OT? Aluminum Metallography?

    Has anyone here done in-house metallography on aluminum? Any tips for sample prep and a (relatively) safe etching solution? I have a number of weld specimens in 1/16" aluminum I'd like to do metallography on to examine grain structure and look for voids and areas of poor bonding. There are...

    Source for 6061-T4 Sheet?

    Title says it all, does anyone know a source for standard 4'x12' sheets of 6061-T4 aluminum in .060-.063" thickness. California vendors/distributors preferred, but I'm not afraid to have material shipped farther. Prefer USA material but beggars can't be choosers. So far my sheemetal vendors...

    Any Demand for Large Reciprocating Air Compressors?

    My company needs to get rid of a large (100hp) 1955-ish Joy air compressor. It's a 2-stage piston compressor with a water cooled intercooler, 120psi max. It looks identical to this, except it's got a slightly different control and is in cosmetically new condition...

    Bought a 10ee... Ended up With Two

    I was offered a too good to be true deal on two 10ee's surplussed from a large company. I figured one would go to work and the other would stay. It turns out one doesn't run, so my company decided to buy a rebuild or new rather than deal with an unreliable drive. So now I've got two identical...

    Flying With Magnetic Bases?

    Have any of y'all tried to take a Noga mag base and/or an indicol through airport security? Did TSA give you any trouble? I need to fly with some measuring tools/indicators and strongly prefer not to deal with checked baggage.

    Max Sheetmetal Sheet Sizes?

    Stupid question, but is there anywhere one can buy aluminum sheet (1/32" to 1/8" thick) in sizes larger than 48"x144"? Metric gauges would also be fine. If it matters, alloy is 6061, but also interested in 2219, 2024, and 7075. Also I'm all ears about good sheetmetal suppliers in nor-cal. I'm...

    Looking for Large Universal Horizontal Mill (Cinci #4 or bigger)

    It's a long shot, but I'm looking for a large (48" x travel or more) manual horizontal mill. Universal table would be ideal, but a plain horizontal with a universal head would also work. I need to be able to set the spindle at an angle relative to the x-axis travel. Details, machine needs to...

    Hard Turning HSS - Speeds, Feeds?

    Does anyone have any good starting speeds/feeds/DOCs for hard-turning M2 HSS? Short tool-life is fine; only 1-2 parts per lot. I'd prefer carbide but will buy ceramics if carbide won't even last 2 parts. Stock diameter is ~.4", will be turned down t ~.1" OD with ~.1" OAL. Tolerances are loose...

    Trouble Receiving Programs, RS-232 Fanuc 18T

    Trying to backup parameters and programs on a Fanuc 18 control via RS-232, and the programs received by the computer are unreadable. The computer seems to read every program character (including line breaks) hundreds of times, so for example the opening line of the program will be thousands of...

    FS: 66 x 120" Manufacturing Lathe/Welding Positioner

    Betts-Bridgeford lathe, originally made to produce 16" battleship shells, or so I'm told. The war ended before it was put to use, but it has since been modified to act as a combined welding positioner+lathe for rebuilding large rolls by building them up with weld followed by turning back to...

    First Turning Center: Hardinge T42?

    Looking at my first turning center, a 1995 Hardinge Conquest T42 with Fanuc 18T control. I saw it run good parts. It doesn't include a chuck or much tooling. Window glass is cracked from an impact. It also likely needs new thrust bearings for the Z-axis. (Z-axis rumbles when jogged, though the...

    SSRs to Run Two Motors off One VFD

    Is there anything wrong with running two different (but identical make/spec) motors off of one VFD? The VFD will only ever drive one motor at a time, and both motors will always be fully stopped when switching the VFD from driving one motor to the other. The motors and VFD are going on a...

    Video: Milling Ice Cubes

    Milling ornate sculptures out of ice cubes, seems like an unusual project. Kinda cool how they can just pour a little liquid over the part to polish out the cutter scallops. If only mold polishing were that easy. https://www.youtube.com/watch?v=VAAnyUjiNGs Suntory Whisky 3-D Printed the...
