Re: [Drakelist] Stuck screw in PTO knob.
Yeah, I looked for that after I got it off and I was lucky: the knob was barely on, apparently (enough to be a pain, though!). The old setscrew had rusty threads about halfway down from the top. It should serve to remind everyone that, when cleaning these old knobs, it's the best idea to remove the setscrews completely and not reinsert them until everything is bone dry. I'll be taking a night off from cleaning this rig while my XYL and I go to a Durham Bulls game tonight... 73, Steve, W1ES/4 -Original Message- >From: Garey Barrell >Sent: Sep 7, 2011 10:51 PM >To: Steve Wedge >Cc: drakelist@zerobeat.net >Subject: Re: [Drakelist] Stuck screw in PTO knob. > >Steve - > >Be sure and inspect that shaft before you put the knob on again.

Re: [Drakelist] Stuck screw in PTO knob.
Steve -
Be sure and inspect that shaft before you put the knob on again. Twisting one off like that will
often leave a spiral groove with raised edges on the shaft. Burnish it down until smooth with fine
sandpaper or steel wool.

Hi Steve,
WD-40 is not really a lubricant, it is a "water dispersal" (hence the "WD"
in the name)
mixture, though it has some lubricant properties. I have made that mistake
myself, for
example trying to use it to lubricate the hinges on the doors in the house,
where 3-in-1 oil
was clearly the better choice.
I dunno what would be the recommended thing for your predicament, but I'm
sure folk will chime in.
For loosening up stuff on the 1950's tractors I got, "PB Blaster" is the
chosen stuff, though
it might be totally inappropriate here. Actually, another thing does come
to mind... I
rotate my own truck tires, and when the shop tightened them too much,
Marvel Mystery Oil
really did the trick, let it sit a few hours.
Good luck,
Chuck, K1OM

Re: [Drakelist] Stuck screw in PTO knob.
Thats luck Steve:
I would sometimes rather be lucky than good!
Not sure who suggested it, but they never tried drilling a hardened set
screw out of a plastic housing. Not much chance of that happening in a
normal home shop---even a toolmaker would cringe at trying that.
Oh OH Ohhere's a way to get stripped screws out: COnnect the ground
lead of your welder to the shaft. Connect the hot welder lead to a pc
of good steel stock and shove it down the whole so it welds itself to
the screw. Now use the welded on "extension" to remove the screw.
Not sure I would try it on a museum quality radio, but hey, mine don't
all look that great anyway! ;)
