    conductive lubricants

    In my experience many electrical connections benefit from some kind of "goop", to retard oxidation, exclude water, prevent corrosion, lubricate, and make future disassembly easier, I know there is a standard product used on aluminum connections, but I do not know how suitable it would be on...

    Tool handles and simple machines

    One of my favorite tools, this time of year, is the splitting maul. When I was taught about the "simple (fundamental) machines", I recall the list as, wheel, lever, screw, wedge. After years of pondering, I think there are actually six, but not all of those four are really fundamental. My...

    Gasoline or diesel torches

    I saw somewhere on PM a reference to an oxy-gasoline and/or oxy-diesel cutting torch. Because of the cost of acetylene and worse yet the condemnation by my helpful supplier of most of my old acetylene tanks, this sounded attractive. Apparently there are two companies making this sort of...

    Sticky acetylene regulator

    I have a nice 40-year-old Harris 2-stage acetylene regulator that has become "sticky", that is, the gas pressure pulsates with a clicking sound. I took it apart and cleaned everything...was not very dirty. No change. Eventually I lubricated the second-stage valve needle*, and that fixed it, for...

    Grinding wheeels likely to go cheap at auction in Arizona

    My only connection with the seller is that I bought a truckload of guy-strand from them several years ago, so i am on their e-mail list. I know nothing about the wheels, and do not know how much the seller will be able to tell you...

    Portable inverter

    Not all my work can come to my shop:I sometimes have to go to it. My engine-drive welder has no auxiliary power. I have used a small, cheap inverter (400W cont., 800 peak), running off my truck battery. I want to buy a slightly bigger one to drive bigger portable power tools, say 1000-1500W...

    Peerless-Racine hacksaw out of stroage

    I rescued a Peerless-Racine power hacksaw from the scrapyard, shortly before I moved to my present location 30-some years ago. Building a little shed space last Summer combined with needing to cut some 2" shafting for a customer a few weeks ago, combined to motivate me to take it out of...

    Pump cups, piston rings, and forming UHMWPE

    I am overhauling an old FH Myers double-acting hand pump, 5" bore and slightly longer stroke, to pump used fryer oil from a receiving ("dirty") tank through a filter to a ready-to-use ("clean") tank. Not expecting clean enough to fry more taters, just to burn in Diesel engines. Will be making a...

    Close fits or Ludwig Loewe Lapping?

    In a recent thread about the hope of making hydraulic cylinders so closely fitted as to need no seals, one responder alluded to a process developed or used by Loewe's company in the late 19th or early 20th century that improved submarine design....I guessed that he was referring to Diesel...

    Measuring or clamping tool?

    My son brought this home from the flea market. A good eye he has! I could not tell him what it is. It is heavily built, and shows wear as from hard pressure against some hard surface along the edges Overall length 7" collapsed, 11" fully extended. The screw is buttress threaded, with a...

    Old acetylene tanks

    I own my own acetylene and O2 tanks. Do not need to pay rental or demurrage, whatever the racket is called. I am happy to pay the modest cost of periodic testing of the O2 tanks. Never had one fail, even the one made in the 1940's. I am careful with them all, re-paint as needed to keep them...

    Powermatic belt sander tracking

    A customer tasked me with repairing, if possible, tracking trouble on a 6 x 80 Powermatic belt sander. Apparently the mfr is aware of the problem because they actually replaced the machine. I have some guesses about where the trouble may lie, but I will wait to see if anyone else has confronted...

    Cutter for wormwheel

    A customer bought a 1970's Chinese lathe. Half-nuts and a little bronze wormwheel in the apron are trashed. No parts available. Easy enough to order a stock Acme nut for the leadscrew and fit and split it to make new half-nuts. 19 tooth, approx 32mm OD wormwheel not so much. Teeth are...

    indexing head ID

    I dragged my indexing head off the shelf onto the mill table, to cut a little worm-wheel (subject of another thread!), and decided to take photos and see if anyone recognizes it. It is obviously missing the external gearing. I have only the index plate for it that is on it now..fortunately...

    Making brake hoses

    Brake hoses were not available for my 1962 Peugeot when I rebuilt it in 1976. A wonderful old-school place called Trenton Brakes i nTrenton, NJ made me new ones by cutting off the (metric) threaded part and silver-soldering it to some reusable screw-on) hydraulic fittings, and adding new hose...

    Durbin Durco "fence stretcher"(?) strill in service

    Maybe this should go under "antique", but here is one of my favorite old pieces of iron still pulling, in this case a stone weighing about 400 lb. Probably a harder pull than that becuse the stone was doing quite a bit of bulldozing on the way to its new home.

    Plain bearing spindle speeds

    I am looking for some education. It is a truism that plain bearing machine spindles do and must turn slower than rolling-element bearing spindles. However, IC engines almost all have plain bearings supporting the crankshaft, and these run at many thousands of RPM. I have read the articles...

    Anyone heard of Honeoye Induistries?

    A customer brought me the carriage of his "new" lathe, looks like 10-12" swing, nameplate says "Manufactured for Honeoye Industries". I have not seen the whole machine. The half-nuts he needs I can make out of COTS 3/4-8 Acme nut, . The 20T, approx 1 1/8" PD wormwheel for the feed may be...
