    How Do You Make Tiny Copper Washer Gaskets?

    As previously suggested, grind the parting tool so the groove cuts through first on the washer side. Then I use a Noga hand-held internal deburring tool. Every shop needs one or two!

    Holding down straps

    Also check eBay. Many sellers ship using their "Global Shipping Program", which is often astonishingly cheap and fast.

    Is diesel oil compressible ?

    For all practical intents and purposes, fuel oil is not compressible, just like virtually all liquids (by definition). When you draw a vacuum on diesel fuel trapped in a cylinder, it will instantly boil, forming an oil vapor bubble. The result may seem like "expandibility" (sp?), but it is not.

    Myford oiler - advice needed

    I have found that leakage out of the spout tip seems to at least partly occur due to daily changes in temperature or barometric pressure. On those oil cans, leaving the cap or top loose between oiling sessions seems to minimize leakage from that phenomenon. That "paper towel diaper" fix is...

    Myford oiler - advice needed

    Mike, Here in Pennsylvania we use most any high-quality pump-style oil can to force oil past those tiny spring-loaded balls. Currently, I'm using vintage oil cans made by Eagle, here, or Reilang in Europe somewhere. Vintage oil cans from Sears, Roebuck (Craftsman grade), Plews, and Gustave...

    Help with Rider Ericson casting

    Greetings, If it were me, plan "A" would be to obtain two replacement castings. Plan "B" would be to have someone take a few minutes and re-attach the leg by TIG welding it. Then I would heat the other warped casting red-hot and carefully straighten it. If it is cast iron, it should...

    What have you been doing today?

    I have one of these Perkins spring winders also. I've yet to try to use it as I do most of my spring winding on the lathe. I don't have a very large complement of accessories for it and it seems like it will be fussy to set up as you are winding the spring in mid-air, not around a mandrel...

    why people like low speed hit and miss engine?

    You may be missing the distinguishing feature of the Atkinsom Cycle, that each of the four strokes of the cycle is a different length. The power stroke is the longest, giving a greater expansion ratio (and therefore higher theoretical efficiency) than does the Otto cycle. Producing a...

    LMS Sieg SC4 Popping My Ground Fault Interrupter

    Your problem is the radio-interference reduction capacitors in the various components. As they absorb from and release current into the circuit, they confuse the GFCI circuitry. Vintage military-spec Porter-Cable portable belt sanders are the classic example in which the included instructions...
