Default Shaft Extention

Hi Guys...
I was just a a deal today and found a few things that
might interest this Group.
17 ea 1/4" Shaft couplers square unit w/ 2 -1/4" holes
each side but NO set screws.. there $1.50ea
6 ea 1/4" Universal Joints 1/4" both sides there $2.50ea
I do have a $20.00 minimum order but thought someone
might be able to use these. email me directly
steve.apexjr@prodigy.net
Check my website for maybe other items of interest

sorry for bumping old thread..

peter, how do you make the shaft sits firmly on the front panel while rotating? i still can't grasp the whole idea by reading your words..i'm planning to make an extension shaft for my potentiometer too

I'm not Peter but I have seen bushings, somewhere
but I also need to fix this for my own project

but drilling a precision hole should do
I might drill smaller
and then use a small needle file
and give a tiny amount of grease
tho, I think a press fit nylon bush would be optimal
those I haven't seen anywhere

back/forth movement is held in place by pot/extension fixing

be aware there may be both 6mm and inches equivalent, which is 6.3mm

Mouser has the press-fit bushings made by Keystone, but they might not be in the catalog.

Also not Peter....but I have used some brass tubing barbs as sleeves:

Double Barb Fittings for Tubing: Male Connector

Just drill it to the exact size, cut the unused barb part and press-fit or thread into the faceplate.

Brass is ideal as it is 'self-lubricating'.
I also have one pre-amp with a stainless shaft turning directly in a precision hole in the 10mm aluminum faceplate. It binds without oil/grease.

Here is a product to extend shafts: Set Screw Stainless Steel Shaft Couplings - Stainless Steel Shaft Coupling Company. , your local building supply store should carry 1/4" round alumimium rods. As a support through a panel I would use standard nylon snap bushings. E
