Question about machine buffers

I was telling my hubby about the PC orbital buffer. He asked why you wanted an orbital buffer. As soon as I started talking about rotaries and swirl marks, he said, "Well of course you want orbital in preference to rotary, but why not a reciprocating buffer?" Can anyone explain?
 
I have a reciprocating saw, which is used like a rotary turned side ways. I believe a reciprocating would actually be a rotary. Explain to him that an orbital is the right fit for the particular purpose.



BTW: what happen to the hand method...just joking we all go to the PC sooner or later.



Ok, that must have been a sander I had, thanks. Oh yes alot of vibration ( in the one I had). That was a circular saw, well its time for me to go home.
 
I haven't gone to the PC yet, still using the hand method. Just talking about it. A reciprocating buffer wouldn't be like a rotary, it would go back and forth. To me it sounds like it would have less circular component to it's "travel" than an orbital.

just say " An orbital is dummy proof so even you can use it."

Are you trying to get me divorced? :eek:



I thought it was an excellent question. To me it sounds like a buffer with no circular component to its trajectory would be even less likely to put swirl marks. I don't know if such a buffer exists. I don't know if it would be really hard to manufacture such a buffer. I'm just wondering if there is a good reason that such a buffer isn't used.
 
ok, ok in all seriousness.



If a recrip. buffer is liek a recrip. saw then it has a force ful jabbing motion. This would not be good around body trrim, mirrors ect. becaue it would crak, dent, or jab them off.
 
Aha, that might well be it. It may be really difficult to make a reciprocating buffer with a gentle finish to its stroke. I'm wondering if there are other reasons.
 
To my knowledge a reciprocating buffer does not exist, I have never seen one.



But, I can tell you problems with it. Due to the nature of the movement they would be prone to high and low spots (at the far ends of the travel stroke) and also very prone to gouging the painted surface. Also, with a front to back motion you could easily see machine lines in the painted surface.
