Topic: Knee Mill Repair (8 msgs / 225 lines)
1) From: Jason Brooks

Hash: SHA1
I was grinding with my trusty knee mill the other day and the handle
popped off.  Looking at the bottom of the handle, I noticed that it looked
like a basic  'rivet' end - the soft metal of the shaft was hammered into
a small head to hold the shaft on the grinder arm.
Now, I'm definitely going to need this next week - traveling.  So, does
anyone have any suggestions to repair quickly?  Turn it up and, with some
cushion, re-hammer the rivet with a punch?  Other ideas?
Thanks,
Jason

Is this a Zass?
Can you supply a picture of the damaged part that we can look at?

Sorry - yes, it's a Zass.  There are pictures up and you can start here:http://www.flickr.com/photos/javajeb/2233089449/There's not much clearance of the shaft beyond the bottom of the grind
arm.  So, it may need to be replaced.

Hi Jason,
The only fix I can think of is to replace the pin with a threaded
bolt/screp, and tapping the arm....  I did that on an old zass, and it came
out great.  I don't have the tools anymore, but any machine shop might be
able to do this for you for $5 or $10...
Sorry man - hope it gets fixed....

Just a thought ...
Go to the hardware store and get a kitchen cabinet knob that is
already threaded and a long screw to fit.  Also, get two nuts that fit
the screw and two Teflon washers of the same size.
Put the first Teflon washer on the screw, then push the screw through
the hole in the handle.  Put on the second Teflon washer and run the
first nut down enough so that the screw it a tad loose, but not too
sloppy.  Run the second nut down and right up against the first nut to
lock it in place.  Then screw on the kitchen cabinet knob.
Might work ...

If it were me I would grab the steel piece with some tapered vice grips,
hold them in a vice,
file it flat,
center punch it,
drill and tap for a 10-32 flat head screw.
But that's just me.
PeterZ,
thinkin of old machinist days, here in LHC

Interesting solutions all.
I do have some machinist tools floating about - tap and die set that was
my g-grandfather's.  I have plenty of vice grips.  But I don't know that I
have anything to hold the steel straight and steady in a press.
I'll have to do some looking over the weekend.  But this should be enough
to do the deed.
Thanks all!
Jason

You might use a roll pin (Spring pin) of the right size. They're hard, where
a rivet would be soft. -ro
