Terry, Great comments about saddles on a Dead Horse --Thanks Harold , I don't understand the part about using the mill ? Is it just have a anchor at one end ? Did you want to check the entire length of cable ..is that it ? There are many suggestions, but they take equipment you may not have like fo...

In many jurisdictions the labour law specifies a factor of safety of 5 for material hoists; a factor of safety of 3 for material lifts (think lift truck); and a factor of safety of 10 for personnel hoists. Underhook appliances such as spreader and lift beams, magnetic and vacuum attachments for lift...

Make it from titanium and it should last a life time, I think. Stainless steel metallurgy, especially corrosion resistance of the austenitic alloys, is a complicated business. In another life and another place I used type 304L austenitic stainless steel by the 100's of tons. No exaggeration! And cle...

For mechanical engineering calculations it is indeed invaluable.
For generating design ideas... not so much.

I did not think of the jam nut. Good thought. But, the real question at this point, what would you use for a bushing in the wrist pin hole? I need to bore it out and bush it. How big? maybe an 1/8 diameter oversize. What material should I use to bush it? Brass, Silicon bronze, 1144, 1018? Wrist pin...

The way to determine the order of machining the various features of a part is to analyze the functions and the required accuracy of said features. Then it is necessary to estimate the accuracy of the alignment of the machined features and the impact thereof on the assembly. In the OP case with the c...

To gain the knowledge you seek you need to read, read, read, and talk to knowledgeable people. For reading I'd suggest back issues of Machine Design magazine, the Home Shop Machinist, and Model Engineer's Work Shop. You Tube is not bad for getting ideas, either. Knowledgeable people may be difficult...

I got a little carried away with this birthday present for a friend. Elm box and jeweled 1.5 inch hobby vise. Gift vise.jpg My friend liked it though. --earlgo Beautiful! My high school machine shop teacher taught us to do it with a wooden dowel and valve lapping compound, in a drill press. We'd cl...

ya it seems side rods are one of the prime applications of CNC to even one off builds, there's just so much setup and various operations on prototypical profiled and radiused rods. When I began building my CPR Hudson, 'ol 2888, in 1985, I had neither milling machine nor band saw. My machine invento...

Wolfgang, You are closer to Ted than I am. Can you ask him which pumps does he have - the MOE's ones? And has he run these steam driven duplex air compressors on steam and not just on air? Also, when the pump is shut down will it start up again reliably on steam? Also, I think he would trust you to...

Carrdo, methinks that Ted McJannett has two of these beasts in working condition. Why not give him a call and see if he'll let you disassemble one:-)).

Depending on the quality of your mill, clamp your vise, on good equal parallels, upside down on your mill and re-machine the bottom. To square up the fixed jaw, remove the hardened plate and bolt the vise on your mill, aligned as you like it. With as large a tungsten carbide end-milling cutter as yo...
