Press fitting joint pins

Never seen that unless you are talking about shorty pins used for joint protectors that are just glued in by a section of the alignment barrel.

I saw on a cue makers web site a description of how to drill a hole and press in a screw with epoxy. I could not believe it. It is wrong on many fronts.

Does he put a piece of tissue paper at the bottom too to "prevent" buzzing?

I have seen 3/8 10 and 3/8 11 with no threads at the bottom.
Just undesized barrel with glue channels.
I hope those aren't accidentally dropped joint end first.
 
Interference Fit?

Press Fit..
Is it same as Interference Fit?
Lots of stored pressure..
Definatly use a collar...
Just my opinion...
The ones I've seen has groove lines for glue pockets on the shank, no threads..
I don't know their designed fit tolerences..
My SW JP Pins have a smooth shank.
When I install them, I bore out the hole with a slight clearence, no wobble.
On those caps with no thru hole,
There's trapped air, so, the air keeps pushing out the pin.
So, I do put a glue groove, cause the line helps bleed out the trapped air.
On caps that will have something on top, I just dril a hole thru to vent the trapped air.

I hope they are and it splits the cue in half. Cue making is an acquired taste and definitely not for everyone. ;)
 
ive seen them and wouldnt ever consider using one in a cue.

ive said it many times. there are some things that just shouldnt be done. this is one

i dont care about "experimenting" in this matter

I've seen that done many times, an acquaintance of mine did every one of his pins that way, using west systen epoxy and banging them in. I thought and still think it was pure laziness. Over a period of three years or more I never saw him split a forearm, although he always measure the epoxy carefully, bang them half way came back a few minutes later and drove them home. Please don't ask for the name.

I just remembered where I saw it. it was Dennis Dieckman in an article on cue making.
I don't think he was necessarily recommending it, just saying you can do it that way. I do remember it saying how when the epoxy was set up you have a stronger thread then wood threads.

dennis does press fit his pins
i gotta admit, the first time i was at his shop and he had me do it,
i had visions of the forearm exploding
but it didnt
guess that old crusty codger knows more than me ;)

When you say press fit, do you mean he actually forces it in to an undersized hole? Does he butter the threads with epoxy first, put it in the hole or twist the screw into a hole with epoxy in it so it feeds through the threads? Can you describe the procedure.

Do you still do it this way? Also. are we only talking about 5/16 x 18 which is a machine screw and doesn't really tap that well in wood? The threads are pretty fine. Does he do this with all screws?

i honeslty dont know if he does this all the time
just the time i was there, i know we did
the overwhelming majority of his playing cues and billiard cues are wood threads
we did this on some masse cues

dennis has a gauge pin 7/1000ths less than OD of a 3/8x10 pin
hole is bored to that size @ x depth
cuts a small key in the back of pin
epoxies the pin and drives her home
i've only seen him do this with 3/8x10's
only metal pin he uses , other than radials
i tried it one time
i didnt have the hole big enough, no gauge pin, and measuring inside with calipers apparently wasnt accurate enough,
and you know what happened
KAPOW! :eek:
when i first saw this being done, i had my doubts
but it works for him and thats the way it is,
everybody has thier own technique
and i will say this, every single pin we did was from perfect to a half 1000ths

my first try at it left such a bad taste in mouth,
i said the hell with this
i'll do what i was doing

it makes sense though, that once the epoxy is setup, the epoxy itself is now the thread

When you say "drives her home" do you mean pushes it straight in or twists it in? If he has key in the pin and twists it he may be making his own threads.
