Thanks Grumpy & point taken, a very good one too
I hadn't thought of that to be honest
(but I know that does happen over time things get tighter)
really it was just to give the guide of where it was set or should be according to the manual anyway
but more so to give you guys the baseline for the discussion..
(and can someone confirm I got that info right just in case)
bare in mind mate noob here
but I'll as the question
since that 4 square was the first and latter was two long sides
am I right in thinking that the later distributes the pressure required over a greater surface area, thereby lessening the "point pressure" I "think" your referring too with the 4 point pin?
(analogy kinda, like thin ice, walking on it or spreading you Weight type idea)
meaning the oblong (two sided) pin, (latter one)
possibly the better idea of the two designs ?
The 1/2" is that more suitable to the job ?
(bare with me on this Grumpy)
I am not quite sure I follow on the 3/8 and 4 point
but that would be my noobness
(lack of understanding)
not what you said..
to me it sounds like you saying the problem is with the 4 points
but yet I think you mean a 3/8 set just really isn't up to those pressures..
Arrhh ok let me rephrase that;
the 3/8 set isn't up to those pressures distributed over only 4 points..is that what you mean?
sorry mate for being a complete nooby here on this..just trying to understand it more clearly
Thank you

Cheers
