I ordered a new pinion return spring from Clausing (in think) and was
glad it was not out of my pocket. Ouch! on the price. Broke a Ben
Franklin real well.
Not knowing anything about yours, brand, size, etc, can't help you.
The inner or outer ends tend break off. Forming a new end on the outer
annealing/rebending is easy, not so on the inner.
There tends to be very little extra length to allow reforming.
Type and brand would be "BigOl'Honkin". There's no maker mark of any kind or
serial number/ID plate anywhere on it. It's currently wired for 3 phase with
a 1HP motor with a reverse but that looks to be a changeout from the
original by a previous owner.
I posted some pics to the dropbox, here's the links:
I had an old Champion I restored once. Didn't even try on the spiral spring;
rather, I made a nosepiece with two ears that slipped over the end of the quill
and I fixed two extension springs to that. It looked a little kludgey, but
worked great, ancient machine is still going strong 20 years later, probably
into its second hundred years or close to it.
I don't have suppliers for you, but there are various types of
equipment that use springs of this sort. The first ones that occur to
me are lawn mower/trimmer rope starters, or chainsaws. Maybe a repair
shop could supply a used spring that you could modify.
If I didn't have some suitable spring material in a junkbox, I'd begin
to look at other machines that use that type of spring.

It looks like either a torsion spring or a flat spring is what I'm looking
for. I''m still holding out on the idea that some company somewhere is
making the replacement spring assemblies complete but I will fab the thing
from scratch if I have to.
People have commented that Harbor Freight usually comes up
with repair parts being available at a reasonable price.
Take a look at the parts blowout here for their Model 38119
5 speed press:
It looks like the quill spring is item 28A (crappy pdf, hard
to read) part number 0804009 on page 15. Maybe a phone call
would get you something close enough to work with your
Another idea you could try would be to mount some sort of
drum to your stub that was maybe 3 inches in diameter. Wind
some cord or cable around this go up to a small pulley and
then back to yet another pulley at the rear of the press.
Hang some weight on the end of the cord, value to be
determined by what works well.
It wouldn't be pretty, but it should work better than not
having a return spring...
Return spring repaired too many times, now too short. Spring 3/8"
wide x apprx. 36" long coiled. Any info would be welcomed.
Rockwell/Delta revised part number 402043205002, old number
402043205001, not available.
Check with Sears repair parts that fit their big drillpress they sold
for many years.
That may do the job with some mods. Quill return springs are usually
duty with the job they have to do. Rewinding a quill having a small
pinion ain't easy.
O.K. You left out the thickness. From MSC (pages 1745-1746 in
the Big Book), you can get coils of flat spring stock. The thickest
sold in 3/8" width is 0.062", and that is available in two coil lengths,
85 feet for the normal coil, or 12 feet for the mini coil.
The thinnest available in 3/8" width is 0.005", and the mini
coil is 39 feet there. (They are sold by weight, hence the weird
If the thickness is not enough, perhaps you can double up two
lengths to form your spring -- and maybe even get more life out of it.
