Hiking Pole Joiner x2

I put my hand up to attempt to make a screw type joiner for New Zealand Hiking Poles for a fellow I know. They were cut in half to bring home from NZ to AU when on their honey moon some years ago. These Poles are not cheap some $120 each they have a coin in the top of the handle.

The drawing and plan was for 24tpi but a mate rang to say his boss offered me use of 16tpi tap and die so I jumped at it. I have not cut threads on a lathe for over 40 yrs. I got to dry fit stage today and turned the Pole to suit they are not true round one being very oval indeed.

Not sure why photos and text stuffed up order. Maybe me and my stuffy head sinus worst this year.

Hi Ray,

Looks a nice job.

> they have a coin in the top of the handle.

If you're caught short out in the hills you can spend a penny without causing a scene.

ES might have been a better choice

Regards Ian.

never thought of that Neil. Thanks

Circlip/Ian not sure what you mean ES???

ES edison screw? Looks like a drain rod joint to me.

Or a rod for sweeping chimneys. Saw some thing today that reminded me of this thread, a two piece Pool Cue in the local second hand shop. I had a look at it, and it has a 8 mm thread in the brass fitting. I think one of my nephews has a three part pool cue he bought in Brisbane.

Don't worry. Drain rods have a far courser thread, more like 6 tpi. You might want to thnk of a way to stiffen the thread so it doesn't undo from the jarring of hitting the ground in use, yet not jamming up. I suggest graphite lubrication from a smokey candle flame as it isn't slippery like vaseline (you wouldn't use oil on a domestic product I hope) yet prevents cold welding. You might consider putting (metric for long term availability) spanner flats on the joint or they will be tempted to get the mole grips out. Show then the old trick of patiently tapping a brass joint to loosen it if jammed.

Well now all it needs is loo roll I guess.

Had been considered by the owner and other willing to do the job but as I pointed out the stress after boring and weakening the strength of the wood centre it would split, shatter break. The use of an outer sheath strengthens even tho I have removed 1/8th to allow reasonable mating of timber and brass.

I had a similar joiner as an example to show the owner,

Bazyle having used the 16tpiUNF its tight and all that would be required once it wears is thread tape or a locking screw through to the relief area above the thread. Even that could undo.

I had considered a Bayonet type fitting with a lock screw but for my level of expertise in machining my limited machines and as job is a FREEBIE I opted for the quickest, stable option that the owner was more than happy with.

Raymond,

In the absence of any clarification from Ian ... I guess this was probably an oblique reference to John Stevenson's recent discussion of lampholders.

Sorry guys, my feeble attempt at jocularity. Brownie points to MichealG for deciphering. Beauty of ES is that even the Ya- er Americans find that hard to cross thread. Cold hands may find it difficult to locate and screw the bits together so a "sleeved" thread may help.

Regards Ian.

Sorry MichAelG .

Regards Ian.

Thanks Michael and Ian for the link and the laugh.

Cold weather in Australia ???? Today is going to reach 34C here in Sydney. Yes we do0 have snow yes it does get down to -10C in some regions unless the owners head back to NZ or maybe Tassie mountain walks where the wind chill cuts through you like an ice princess curse it should all be ok.

If my feeble hands can screw them together the younger owners should be able to.........I hope.

The pool cue I saw had a joint very similar to the one you have on the walking stick. Ray

you better steer clear of parts of town for a while, bit of a worry.
