    My 2 cents on this question: Leave it alone. The milling into the table is relatively shallow and not of a large enough area to affect about 99% of the jobs you are likely to do on that Bridgeport....

    I have a smaller "News" dividing head I bought off ebay some years back. I first came upon mention of the "News" brand in "The Machinist Bedside Reader". Somewhere along the line, I forget where, I...

    Scotti:

    I believe the present-day "shop in a truck" is run by plugging into the customer's power. The customers who need the services of a valve-rebuilding or reconditioning machine shop are going...

    I like the idea of a "vintage mobile machine shop". How this is accomplished is a wide-open subject. A point to bear in mind is that, by WWI, field machine shops for "behind the lines" repair work...

    Additional clues are the fact that the parts all appear to have been made as light as possible (crank webs are ribbed rather than solid, "X" bracing between the cylinders). This points to some use...

    My guess is some sort of light-weight "expansion engine", possibly for an early aircraft (semi-rigid balloon with engine driven propellor ?). Alberto Santos-Dumont had circled the Eifel Tower in an...

    Frank R

    I'd avoid welding or brazing to fill or patch the hole in the Bridgeport table. The table is cast iron, and has been machined over its length for dovetails as well as the top and side...

    Armstrong was using the steel efficiently in their design of the planer tool holder. A bit of basic engineering:

    The shank of the tool holder is a cantilevered beam. The force applied to the...

    Other uses for jewels, which continue into the present day, would include the pivot "bearings" for some dial indicators. In addition, some lab grade analog meters use jewelled pivots.

    I visited Whitechapel Bell Foundry in 1974. My younger brother was studying for a semester in England at the time, and he "discovered" Whitechapel Bell Foundry. Although my younger brother was a...

    With all due respect, if something has a Starrett catalog number on it, it's a production item and not something "never seen". On the other hand, Starrett did, and continues to, make special...

    Doug:

    Thanks for the compliment. As for temperatures and pressures:

    The older locomotives built in the 1850's-1900 used saturated steam. By the later 1800's, 100 psi was a common working steam...

    Some of the photos are fairly modern heavy locomotives. In one photo, the "hairpin" superheater elements are laid out and warped like over-cooked spaghetti, while the first course of the boiler and...

    I had a 1950's Reed & Prentice 16" geared head "heavy toolroom lathe". By the time I got it, it was not a "toolroom lathe", just an old workhorse. For 700 bucks, I got the lathe (which, by the...

    I checked my own die filer, as it is a handy bench-top unit. The name on the crankcase cover-plate is: "Milwaukee Die Filer" and "Rice Pump and Machinery Company".

    On the cast iron baseplate, the...
