Stainless steel Mortar ?
« on: March 25, 2011, 04:06:49 PM »
I was wondering is stainless steel Grade 304 or 316 suitable grade for a GB mortar ? I found a guy somewhat local to me who makes them. Thanks for any info you can provide me with.


Cheers

As long as you stick to golf balls, almost anything would be sufficient, even a banded wooden tube.  I have one in stainless (alloy unknown) and its outstanding characteristic is that it cleans up faster than anything else I have.  The real question is "is it strong enough for heavier projectiles like one pound lead sinkers or the Fox 'golf' balls?"  If you build to a little heavier proportion than exact scale, you will have a larger safety factor.

You pose a good question.

Most stainless steels because of the alloying are stronger than mild steels.

To me the real question is how the various stainless varities will handle repeated firings - that is ductility, the resistance to cracking.  Worth the time to research it.
