I used the procedure given in Machinery's Handbook and got excellent results. On the down side, you have to obtain a copy that is around the 11th edition or earlier as the bevel gear procedure is deleted from later editions. I quickly found an inexpensive early handbook on eBay, which is where...

I recall that lard used to be universally used as a cutting oil. Its major downside was its tendency to turn rancid in warm weather. Lard was also used as a cylinder lubricant in very early steam engines. That must have been an annoying mess, though....

I buy all of my nickel plating supplies online from Caswell Plating. Their somewhat expensive plating manual is worth the asking price. Their plating supplies are reasonably priced and work surprisingly well. Cleanliness and controlling the plating bath temperature and plating current are...

I agree. I apologize for my narrow thinking up here on the 40th parallel. You're stuck with either using a Google Maps satellite image of your shop or borrowing one of those Tates compasses from a migrant.

Go outside on a sunny morning and drive a slender stake in a level area of ground. Make sure that the stake is long enough to cast a decent shadow on the ground. At noon local standard time, as noted by your watch or handheld digital annoyance, the shadow will be pointing geometrically (not...

LOL. Probably old, but still most excellent!

The down sides of John Deere's famous 180-degree arrangement was "second order" side-to-side shaking of the tractor and that the second cylinder to fire drew it's fresh charge from an intake manifold that was already evacuated by the cylinder ahead of it. Deere finally rectified the second...

You're welcome! If you're not familiar with George Luhr's astonishing craftsmanship, here is a link to his fully functional,1/8-inch bore, overhead-valve petrol engine: https://craftsmanshipmuseum.com/artisan/george-luhrs/

I agree completely with Longboy, here. Machine it with only one or two setups max to minimize run-out. I seem to recall that the late George Luhrs made one-piece valves for his smallest engines that had 0.020" diameter stems. Someone asked him at Cabin Fever how he lapped them in . He...

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!

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

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.

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...

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...

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...

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...

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...

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...
