We used to use Spiralock extensively here but ran into problems like availibility and price (as mentioned already).
Our biggest problem: tap quality. We use a lot of high strength materials and our machine shops were complaining of constantly breaking Spiralock taps. Of course, if you're using...
Thanks for the offer Kwan but it won't be necessary. In my application, the tensile failure is more serious than a compressive failure.
On that note, thanks to all for their replies.
But back to Kwan's soapbox, I actually enjoyed the FEA discussion on the side. It's given me some real...
I am trying to determine the buckling load for a custom built hydraulic cylinder. Of course my fist thought is to use Euler's equation but I'm thinking that only applies to cross sections that are constant.
Since it is custom, the manufacturer has been of no help.
Another engineer here at work...
