Yesterday and today have been unusually cold and snowy for this area, and tomorrow and Friday are expected to be just as sketchy. Many businesses have closed for the duration. Consequently, the few of us that have made it into work, have unexpected time on our hands. We are tying up loose ends...

Thanks All. Appreciate your considering and responding to my post. As you have suggested is what we have done, follow the data sheets. K.

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 -...

Thanks All! for considering and responding to my post. Really high quality answers here, and dpc, Thanks again. It makes a world of difference when you know the correct terminology. Appreciate the help. K.

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...

Just checked back for... Idon'tknowwhy, and WOW! Thank You. K.

Thank You itsmoked. That was very informative on several levels. Appreciate your help. K.

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...

Thank You gearcutter and tbuelna for considering and responding to my post. Yes, the helical angle was supposedly taken into consideration by the manufacturer that created the end mill. But even with that manufacturers assurance that the profile they created is correct, everything about this...

ref http://www.eng-tips.com/viewthread.cfm?qid=383133 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...

Thanks tbuelna. My tech is looking into this now. Appreciate your taking time to consider and respond to my post. K.

Thanks verknde, that's exactly what my tech told me. We are 4x, not 5x. We are finding many Sharpeners that say they can produce any shape end mill, just send them a print. When I ask if they are currently grinding the involute curve their answer is always something to the effect that they can...

Thanks all. Apparently I've been cutting gears too long on dedicated machines to see beyond the norm. You have provided us a new path. Appreciate the help. K.

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...
