Anybody tried pine tar?

You started with the "Engineer" nonsense and any insinuation relating.

You also felt the the need to step in for no reason what so ever, to offer an opinion in something that was not asked. Cleary bored or experiencing some bunching panties perhaps...can't say. :)

Beyond that....If you prefer to believe that a 'Loose' fitting radial joint in a pool cue is correct , desireable or in some way the ideal condition that one would expect to achieve when creating that union.....

Then I'll just let that stand alone in regards to any question of 'good' as it relates your engineering.

:grin-square:

Geez...name one name I called anyone ?

Troll ?

You came in from nowhere and started this whole line of debate? (over a completely unrelated and non applicable point BTW)

Sorry if it's not going your way but you never stated one thing you claim to have been trying to.

FYI.....:grin: :) :wink: :smile:

Theses thing I intentionally use to imply intent. Don't get all fired up over nothing.

Sheesh.

I have a radial jointed cue that certainly feels like an interference fit. I don't feel like measuring roots. It's tight.

I also have a radial jointed cue that felt like a slip fit and it did unloosed during play. It's been cured with a new joint.

My other radial cues... I don't know what the fit would be, but they're tighter than one the latter and looser than the former.

HTH,

Freddie <~~~ but I can't see how

IMO...

Lemme say it gain...

IMO...

I properly constructed radial joint should have no perceptable 'play' without being 'tight'. The idea behind the radial interface is that ability to remove 'virtually' all play in the union without creating "Excessive" or destructive friction or resitance in an interface expected to see alot of use.

This is the primary reason why it is so prevelent in machine controls using "screws" , opposed to something like an acme thread which is also used commonly. (Manual machining typically)

Screws are screw and all have many attributes in common , this is not where the discussion was going (IMO), but was only about acceptable tolerances in creating a joint of this type.

Clearly.....opinions vary. It's good. :)

I never thought you were and idiot, it just seemed you wanted to debate a different issue.

I obviously don't think a "TIGHT" screw interface is ideal. I think in the case of a radial pin, there should be virtually no perceptible play. ie Not "loose". Excessively tight is not good, interference fit , as it is classically interpreted, clearly bad...unless your only putting it together once. :)

Now finding that relationship can be quite difficult for some and some may even prefer to error on the 'loose' side. Personally I feel differently in the case of pool cues and would much prefer a hair on the 'snug' side to loose or sloppy fit. I think the negative trade offs are well in that favor. There's a reason why radial taps are available in the various 'off' sizes to help achieve this relationship when using dissimilar materials. (wood/metal)

Undersized Radial taps?

Probably diverging a bit from the original "pine tar to stop a joint from coming loose" topic, but I noticed that specifically with the Radial pin, Atlas Billiards Supplies has in stock Radial taps that are intentionally "undersized for a tight fit":

http://cuestik.com/store/product.asp?DEPARTMENT_ID=129&ITEM_ID=5992

I know that on the two cues my cue luthier made for me, he used the undersized tap, and man(!) you really have to put some elbow grease into joining and unjoining the cue. But it apparently makes the fit of the joint last that much longer.

Thoughts?

Heh-heh, turns out this is partly correct and now I see why you think I am an idiot. I had written a post that explained why radial threads (which are usually coarse) and coarse threads in general would be susceptible to loosening. Apparently it didn't post.

Basically the coarser the thread, the more likely it is that impact and vibration will cause the thread to loosen.

I did, however, tell you why a tight screw is bad, which is in reply to your statement about the radial screw.

Looks at that ,see ? We agreed the whole time.

I never said it should be "tight" and I agree that a course thread is more likely to break loose than (I assume you meant) a fine/r thread.

The catch in pool cues is that most people generally prefer some kind of "quick' engagement and IMO, a properly fitting radial pin is a good compromise between twisting it together for days and something like a uni-lock that falls aparts when you lean against the bar.

:grin:

I thinks that's probably debatable but as I stated above your post, I would err on the snug side if given the choice.

I don't think it should be.... (I swear I'm not typing this word again)....Tight. Which is clearly a subjective term. But I do believe that an overly 'snug' radial pin is less likely to degrade, gall or worse than a comparable relationship using a 'machine' screw.


Alrighty....

Enough of this one for today. :)

Hmmph! Regardless of what people say, the Radial pin is my favorite. So there! :p

-Sean <-- all kidding aside, has a couple cues he's considering having the pin replaced for Radial
 
Especially if you screw the shaft on while the glue is still wet!

I did that once Paulie. The operative word being ONCE.

I also poured the excess glue out on my hand instead of hitting the cup.

I can be a very dangerous man around CA at times. A can of Acetone is always near by.
