how do i extend a tuning shaft?
 

So im putting a late 50s fm tube radio into an empty 20s case. I need to extend the tuners shaft a good 5 inches. what will i need to do this?

Maybe using another piece of 1/4" rod, with a collar to connect them?

If im getting the terminology wrong, im sorry.

but any help would be appreciated. im making this radio appear stock from the outside, not changing anything internal. in case i find an original chassis.

I dont know where to get stuff off the shelf but a ham
flea market will have all kinds of stuff like that. There are
couplers that use set screws & shafts. Just be sure to
get the right dia. etc.

If the shafts are long flexible couplers may be worth using.

:thmbsp: In the scrapping of old oscilloscopes , I have seen lots of shaft extenders being used . If you have any junk scopes kicking around you might have a look and see if your needed extender can be found in there .

Hah, i dont even own an o-scope anymore. My heathkit scope was borrowed and never returned. I now have a rule, i will lend to friends, but never family. You can choose friends, but not family.

Luckily i found a shaft coupler for sale online. 1/4" to 1/4", so it will work fine for my needs. Now i just have to go to the steel store and get some 1/4" rod to make my shaft.

Another option would be to give your radio Viagra. :D

My '51 Zenith porthole chassis uses 2 shaft extenders, and they are quite long. They are the splined type.
