The first picture below was gonna be really cool, but apparently I have a case of Intermittent Middle Age Shakes. :eek: :confused: :mad: (Never mind that the camera's shutter speed is way too slow, and that it came free with my now-retired Dell printer. :rolleyes: )
EDIT: I took a much clearer picture (#2) outside today. :cool:
+++
I kept thinking that Centuri's PNC-74 was "pointier" than Carl's BC-734P. (For the record, I *love* that shape! :cool: ) So I dragged out my limited collection of Centuri cones and some Semroc counterparts.
Below (left to right), the Centuri nose cones are PNC-73, -74, and -76.
The Semroc cones are BC-723P [PNC-73], BC-735 [closer to PNC-74 than BC-734P], the aforementioned BC-734P [PNC-76?], and BC-730.
Now if my picture had turned out as clearly as I *hoped* :mad: , it would be obvious that:
1) The two cones on the far left [Centuri PNC-73] are basically identical in shape.
2) If you round off the very point of the Semroc BC-735, it's a dead ringer for Centuri PNC-74. (Oops! I even managed to "bash" off the point of the balsa cone while handling it.)
EDIT: The next paragraph was re-edited for picture #2 below.
3) The tip of the [next to the] last cone on the right (Semroc BC-730) isn't quite as round as the BC-734P (which *may* be mislabeled). However, the BC-734 is nearly indistiguishable from the Centuri PNC-76... :confused: which is [second from the] right at 3" long.
The point of all this rambling is, I *think* more accurate Semroc substitutes for these Centuri parts would be:
Centuri -- Semroc
PNC-73 -- BC-723P
PNC-74 -- BC-735
PNC-76 -- BC-734P
The problem with being analytical at work all day is that it spills over into my hobbies when I'm *off* work. (heavy sigh) This all got started when I read the Centuri "Sky Devil" posts, and promptly went downhill from there.
Carl, is your BC-734P (WHICH I LOVE!) supposed to be 3.4" long [Centuri PNC-74?], instead of ~3.0"? I'm not trying to nitpick, (mock sobbing) I JUST HAVE TO *KNOW!*
Or not.
Cheers, as always,
