Flat Wrenches
 

I'm sure most production flat wrenches are punched out of a piece of
sheet, and deburred.

I need to make a couple flat wrenches for some collet chuck tool
holders, but I neither have such a huge press, a desire to make a punch
and die for one of each tool, nor stock on hand of suitable thickness.
What I have handy is 1" thick flat bar. I was thinking I might cut my
wrenches into the top surface of the flat bar, slice them off with the
bandsaw, and then grind them roughly flat with a bench top belt sander.

Maybe look at DIN 894 single ended spanners as a solution as I've used
them many times when users of my tools have buggered the standard
punched steel spanners byÂ* over tightening them and I demanded a
replacement.

They seem to be cheap enough depending on the source.

Good old tappet wrenches were drop forged alloy steel.

Dull circular saw blades can be annealed, shaped into tools and
hardened. Tin can steel makes an adequate one-use heat treating pouch
to minimize scaling. I got my stock of dull blades from a carpenter
who was cleaning out his truck, and use my wood stove to heat them.

NOT carbide tipped blades, I assume.

IIRC a coupon from a carbide blade also hardened. I did this a long
time ago and didn't take notes.. If you have a wood stove it's easy to
test a sample. I watch out for free sources of hardenable steel in
various useful sizes and shapes.

If you would like to just buy some decent thin spanner wrenches take a
look at the ones made for bicycle work. I have a few old (~25 years)
Park wrenches and they are pretty good...

If you have access to a Plasma-Cam type machine I suspect they could
blow out wrenches pretty quick :)

I always check places like the Habitat for Humanity store before making wrenches.

Yeah, I ought to go over there and wander around more often. Its not
far from my shop. Maybe closer than my favorite nuts and bolts vendor.
The problem is I always seem to find something I really don't need and
it follows me home. One time I found some new still in package 3/16
threading dies... They are still new in package a year and a half later.
In fact the only thing I can think of I have ever used with a 3/16
thread is one particular size of toggle bolts.

They used to let me look through their trash/recycle bin here. Picked
up all sorts of odds & ends for basically scrap price or what ever they
made up and I agreed to. They got a new manager that took a dislike to
me and that was that...

Hear Hear!!

Even Harbor Freight wrenches can be ground thin on a surface grinder
after being hawged thinner with a belt sander.
