I’d basically agree with Kelly also; because = with the complex stress patterns in that plate it is very unlikely that that = =BD the thickness would only double the stress; and the deformations would be = larger making fatigue failure in areas of the plate a serious concern.=A0 = Can’t be worth the risk for 3-4 lbs.

Thanks, Dean, but the RD-1 measurements won't be a consideration.=A0 I =

have a different PSRU.
