Cees,

As I suspected we are completely off topic. I thought this had to do with my learning curve and D-tube holes. Now you've decided to discuss Ralph's power supply which has, again, no bearing. If you preach exactitude, engineering and calculations, stay focused - stay on topic, don't take me for a walk in the wild.

In any case, you completely misunderstood me in the post you've chosen to quote me on above (as expected - a runaround of past information with no relevance). I was not burning those PSU's down, I was elevating Ralph's!

I don't doubt they are excellent PSU's and for that reason I mentioned they looked suited for a hospital but that was Ralph's foam cutting PSU build thread. Interjecting the fact that perfectly usable supplies exist for a foam cutter in someone's purpose built hobby supply is somewhat rude. I'm sure Ralph was well aware he could buy one if he chose to but what he chose to do was to build one for himself. And of all people you are often suggesting to others to build everything by hand which is a nice approach I admit. Sometimes others might prefer to use a commercial hooded pushrod exit guide even if it doesn't conform to your sense of aerodynamics. In this case Ralph chose to build something and you highlighted that there was no need for him to do so since he could just buy one... and not risk blowing up his house... c'mon Cees. The safety of other adult modelers is not really your concern. This is a fun hobby space not an academic safety classroom.

You present things as if you already know all possible future outcomes of people's foolish acts. That's simply unrealistic and unpleasant.

Whatever the case, Ralph has his reasons, and whether they do or do not suit your PSU choice parameters is irrelevant. His build has nothing to do with what you might select or buy - it's his supply, not yours.

Finally, I'd rather promote the sale of Ralph's tested and working PSU as I'd rather stimulate grass roots efforts rather than large commercial efforts. I wouldn't doubt they have a capable marketing and sales department and have no need for either your or my promotion efforts.

Why I'm discussing any of this is beyond me. I'm not sure you have ever been willing to meet others half ways - find a common ground of communication.

Above, you chose to dismiss someone's comment and opinion on the SP I built. You then proceeded to inform them of their complete ignorance on all matters based on some RCU parameters you plucked from user accounts. Doesn't that strike you not only as poor judgment on your part but rather disrespectful? After all, what do you know about that person? Close to nothing, I'd say. In English that is called arrogance and is generally not considered a desirable quality. Be respectful, offer your point of view but let others have theirs and above all, don't assume that if someone does something differently from how you do it, they are a lesser person than you are - from a craft standpoint, academically, professionally, intellectually or otherwise. We know very little about people from online exchanges - it is only fair to give everyone the benefit of the doubt and extend common courtesy.

I'm sure we both have better things to do than continue with this line of exchange.

David.
