Back to metal, where do you guys buy your steel and aluminum plate
for projects? Y'know, foot square or smaller.

I got some motors in the mail yesterday and need either flanged plates
or 3-5" diameter faceplates for them (5/16" D and 3/8" round shafts.)
The need is to convert from rotary to reciprocating motion for 1-10
lbs @ 1-60 rpm. I can't think of the name for the rotating
ball/bushing used there so I can't Google it, either. sigh

the part you are thinking of is called a rod end. You can get them in
many forms and materials. Go to http://www.mcmaster.com/ and do a
search on rod end to see the selection. I used several in my mirror
grinder http://www.jamescrombie.com/pics/assembled4.jpg

I finally gave up and hauled out the MCS, Enco, and McMaster catalogs,
all lebenty seben pounds of them. After half an hour on the couch,
thumbing through them, I found the pictures of rod ends and rod end
linkages. That's what I wanted! Pages 898-902 of Catalog #106.

Thanks to Keith, too, for the Heim joint reference. I had seen that
here and knew that was the same thing I needed but couldn't think of
the term.

The damper crank arm on page 903 might give me an adjustable throw,
too, unless I find inexpensive faceplates.

Now to find what I'd call a faceplate for a wood lathe. 5/16 and 3/8"
shaft collar with 4-6" plate.
