I searched the forum, digikey, Michael Percy, and ApexJr with no luck so far. Where are you guys getting them?
Also anybody got any good pics of implementation. What I'm wondering is what's the best way to secure the shaft at the front plate so that it feels stable. Will I need a bearing or just run it through the hole and leave it at that.
Thanks

I'm using 1/4" long drill bit and cut it to the size. On front panel (for new bushing) I use the bushing from any pot or switch that fits nicely over 1/4" drill bit, the use of some grease is recommended here., On the potentiometer side, for connection between new shaft and pot you can use aluminum standoff with 1/4" hole drilled through (2 screws can be used to hold shafts in a standoff) or any other metal tube that fits tight over shafts.

Look for the "rotary switch extension shaft"
It should work great for pots too.

They make panel shaft bushings that support it on the front end. I have lots extra, if you need some.

why not...
... chopsticks?
You can slice off at an angle, the part that slots into the actual
pot handle and use hot melt on the other end
of the chopstick to glue to the knob.
A cheapskate idea, I hv not tried it though.

Shouldn't be too difficult to make an extension shaft, otherwise
have a look at
http://www.schuro.de/preisl-achsverb.htm
They have both extension shafts and "Kardanlenke" and
whatever you could dream of for your pots. 🙂

SHAFT
Hello,
You will need a shaft coupler at both ends which I suppose can be had from any of the sources mentioned.
Cheers,🙂

Pot extentions
Dustin..........
I have a couple of 1/4" hole 5 1/4" length
shaft extentions in stock. Not everything I
stock is listed on the website. If interested
just let me know

What do you mean?
> Post #11
Use the shafts and couplers from an erector set.
I dont understand the above reference
The extensions at http://sound.westhost.com/purchase.htm look the best but at $21 dollars seem expensive.
Is there a cheaper alternative?

The easiest way to implement shaft extender is to use 1/2 OD / 1/4 ID plastic washer for bushing, 1/4 brass rod for extention, and 1/4 ID PCV water pipe for coupling. All materials available at Home Depot, or your preferred building materials supplier.
Digikey sell part RP383-ND or similar. Unfortunately, they don't have a metric (6mm) equivalent for the european guys...

This is still not a bigh deal. Another way to do it is use a thin piece of FR-4 material (PCB material) or thin plastic, drill it through with 6mm drill, and attach to the panel with double sided tape or glue. The panel opening has to be larger than 6mm.
I fixed this way an off center hole in one of my prototypes and it worked just fine 😉
In doubt
Dear Peter, thanks a lot for your (as usual informative) answer.
Just for curiosity, a few years ago I bought a few of the Digikey washers; the material (nylon?) they are made of looks very smooth and appropriate for the purpose. I have instead some doubts about FR-4 (epoxy?). Correct if I'm wrong, but it seems a bit abrasive to me...😕

In my case, I used very thin piece (0.025") and with brass shaft, it acted as a very nice bushing (providing the hole was right fit)).
This material is much softer than brass (as it's not pure epoxy, but mostly fibre).

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
