For many years, the wording on the side of the drum containing the lubricating oil we put in our helical geared speed reducers said Gear Oil. Our oil supplier always advised us to use Gear Oil for our application and not Gear Lube. We recently changed oil suppliers, which brought a brand change...
I come before you today to appologize to Engineers all across the globe.
Changing the spark plugs in my car was always a simple task - until the right rear plug. Just getting the socket on that plug could take longer than changing all the other plugs. Once the socket was finally on the plug -...
In our office, as well as a few other places within our facility, we have 'cans' recessed into the drop ceiling with regular ballasted 4', T12, fluorescent tubes. As the ballasts go out, we remove the ballast and put in 120v LED tubes. What we are running into is most of this facility was built...
Yesterday morning something happened that got me to a thinkin', and the subject matter is way outside my knowledge zone. See, I'm all gears and levers and such, but the issue in question contains current and invisiwaves. Whenever current is involved, my knowledge is pretty much limited to which...

Our sister company purchased an involute shaped end mill and has cut their first test herringbone pinion on their machine center. The measurements we can check look good but now we need to check the involute curve to see if it is correct...
Very occasionally we need to have herringbone gears or pinions cut. These were a part of our product line which was discontinued in the mid 80's but we continue to supply repair parts. Whenever we receive a request for a replacement gear or pinion, the request is almost always for 1 pc. We do...
For many years we've rated our gear reducers in 'inch pounds'. Lately I've been noticing, mostly automotive and implement ads, torque being rated in 'pound inches' or 'pound feet'. Today I grabbed my Machinery's Handbook and there it is, "...pound-feet, pound-inches, kilogram-meters, etc." Wow...
Three of the structural products we use in the manufacture of our product are small channels, 3 x 4.1#, 2 x 2.32#, and 1-1/2 x 1.12#. All the reference books we have do not contain enough data to properly draw these items when we are drafting fabrication drawings. Altogether it is no big deal...
It's that time of decade for us to consider purchasing more of the one piece V-Groove inserts. The box lists them as RTW brand, Size PGT 10, Grade SC20. Seems as if I remember something about Kennametal purchasing them some time ago but have not been able to discover anything about this on...
After 40 plus years of drafting machined parts, I now have a task requiring a fit to a 12" x 40.8# S Beam. So far I have found many charts in books and online that give all dimensions except the angle on the flange and the outside radius. The only clue I've found so far is that bevel washers are...
Occasionally a customer wishes to install a small Fairbanks Morse combustion engine on our product and they want to know which motor mount they need to use. As you may already be aware, any small FM combustion engine a customer is wishing to use is almost assuredly used because FM quit mfg the...
We manufacture a line of Oil Well Pump Jacks, www.CookPumpingJacks.com. Because our line is at the smaller end of the spectrum, many of our Jacks are also used to produce ag and household water. Most of these water systems are 1hp, sometimes as high as 2hp. Occasionally we are contacted by...
After many years of the shop running the show, we have decided it is time to bring our drawings up to date. Everything was going quite nicely until we came to the sheaves. The Machinery's Handbook has a nice chart that provides K for standard combinations of pin diameter and V angle and OD, but...
For a project we have been brainstorming, we would like to calculate the amount of torque to be overcome to stop an axel on a loaded trailer. Any directions of where material on this subject may be found would be greatly appreciated. Thanks, K.
For the oil well pump jacks we manufacture, we have counterweights flamecut from steel plate. Whenever a question is asked about what material they should be cut from, the answer usually given is that nothing better than Cobble Plate is necessary. The requirement on the drawing is simply 1-1/4"...
Our manufacturing facility is in an old roofing tile manufacturing facility, originally built around the 1890's. The entire property is riddled with brick lined tunnels. We are interested in adding a free standing metal building appxly 50' x 100' x 16' eaves. Current building design calls for...
On occasions we have need of a small quantity of a custom extruded aluminum shape. For the very small quantities we mill the desired shape from bar. For the larger quantities, still smaller then most extruders like to mess with, we pay the price and have the shape extruded. And other times we...
We just screwed up. The drilled hole pattern in some gray iron castings was off just enough to not work properly. It was decided to weld the holes closed and redrill. The castings were welded with mig wire instead of nickel rod. The attempt to drill thru the welded spot with a carbide jobbers...
About the same time Ed introduced us to the Beetles I was working as assembly labor in a shop whose propriatary line was mfgd mostly from cast iron and structural steel. At that time it was explained to me that lockwasers were used under a (NC) nut or a screw head when they pulled up against...
For new product development, we are looking for a plastic ball gear to fit on a 1/4" shaft that will handle a max 25 deg angular change. Any ideas of where such an item may be sourced, or an OEM who may be using such an item will be greatly appreciated. Thanks, K.
