I have a die that blanks a 4" round from .42" cold rolled dead soft steel.
I need to blank .32" thick drawing steel. Do I need to make a new punch?
The clearance for the .42" (19ga) is .004" per side and the clearance for
the .32" (21ga) should be .003" per side. (I think) The blank will then be
drawn into an eyelet with a 2-1/8" id.

Uhhhhh , I think you left a zero out there , Tom . .42" for a grommet ? I'm
bettin' the die you're using will work , though I know absolutely nothing
about punch press work .
What can it hurt to try a piece or six ?

This is guesswork, but my bet is that it will shear, but it will leave one
heck of a burr.

The other possibility is that it will produce an especially thin-wall deep
drawing g, probably half torn.

As its a "round",
id keep the die and make a slightly bigger punch.
It depends on wether you have a lathe and some stock and what kind of
press you have.
Also how many you are needing to blank.
If its only say 100 then a medium hard steel will do perfectly for
such a short run.
Is your tooling is all in a die sets? or are you using open tooling?
here in my workshop ive press tools that rely on the accuracy of the fly
press set up so i just set the die in a bolster, clamp the punch
extension(1in) in the press moving part, bring the punch down in to the
die and clamp down the dogs with the 3/4in t bolts.
this will do hundreds in 1/16th brass or nickel silver or steel.
Now all my tooling is open and the punch is always half hard.
The die is always hard.
when the punch wears all one does, and its standard in the jewellery
business in the UK, is to set the punch upside down in a leg vice and
swell the face with hammering.
Then clear the swelled punch in the die and off you go again.
Hope this helps.

A lot of the new dies will be in die sets. I do have some open tooling but
if it's on a die set, anybody can set it up and make good parts. I did
leave out all the zeros like Snag said (good catch!) the real sizes are
..030" and .042" steel. I'll have to make gazillions of parts on a total of
23 dies. They are for a new line of products. I have 9 punch presses
ranging from 20 to 60 ton, most are Blisses. One possibility if the old
dies leave too much burr is to "bump" the punch. Heat it until it softens
and mushroom the face of the punch then clean-up grind it to a bigger
diameter and re-heat treat.

Ahaaa!! now I see your a real pro, with proper tools etc.
Ive a 25 ton Humphies power press for blanking,
a 250 ton hyd coining press,
2 10 tonfly presses and a closed arch 20 ton.This has a 6ft top arm
with 1cwt balls of iron on each end.
A Dangerous piece of kit. Was blanking some cunifer 10 discs and I was
giving it full wack, i slipped and the handle knocked me down i was in
real pain for several weeks. found out it had broken 2 ribs!
for forming hot as well as cold have 3 drop hammers. 112lbs 275 lbs and
a 500lb one. All from pre 1900.
My favorite tools. I just love big hammers.

Twas in 1987 I hada call from a fellow silversmith to say
one of our kind was retiring, all the new stuff was sold and all the
heavy old rubbish was left.
He thought i was the sort of idiot who would like that sort of stuff.
Well, to cut a long story short, it was a complete drop stampers
workshop from 1851. The drop hammer machine weight 1.5 tons the fly
presses , bolsters dies press tools to match ,catalogues in picture
price lists.
well, I just had to have it ,not being sure what to do with it.
I had been showing my jewellery at the Great dorset Steam fair,and
thought Id like to make the brop hammer machine fully portable, take it
there and mint a commemorative plaque for the event at the event.
I didnt stop for 5 days, ran out of blanks ,went home to press out some
more in any brass, copper sheet lying around.
A great success technically artistically and financially.#
Folk just love to see their plaque being made.
That show led to an invite to take it to Germany, to mint there a silver
coin at a castle on the Rhein, and it grewfrom there.
Buckles, buttons, coins,medals ,plaques, and flattened ali beer cans.
got paid to do it!! at a beer festival.
The 1889 Hazelwood & Dent drop hammer is accurate enough to strike coins
in a collar hot. Results as good if not better than a professional
national mint.
Tho of course its a one shot machine., hand placement of cold metal, hot
from an inert gas tmosphere muffle with tongs.
Last product run was hot struck 40th anniversary plaque 2500 off.
in 70/30 brass. 4in by 2.2 in. Coin proof 3D relief quality.

Great fun, and most satisfying work.

clearance for the .32" (21ga) should be .003" per side. (I think)
The blank will then be drawn into an eyelet with a 2-1/8" id.
Uhhhhh , I think you left a zero out there , Tom . .42" for a grommet
? I'm bettin' the die you're using will work , though I know
absolutely nothing about punch press work .
What can it hurt to try a piece or six ?
As its a "round",
id keep the die and make a slightly bigger punch.
It depends on wether you have a lathe and some stock and what kind of
press you have.
Also how many you are needing to blank.
If its only say 100 then a medium hard steel will do perfectly for
such a short run.
Is your tooling is all in a die sets? or are you using open tooling?
here in my workshop ive press tools that rely on the accuracy of the
fly
press set up so i just set the die in a bolster, clamp the punch
extension(1in) in the press moving part, bring the punch down in to
the
die and clamp down the dogs with the 3/4in t bolts.
this will do hundreds in 1/16th brass or nickel silver or steel.
Now all my tooling is open and the punch is always half hard.
The die is always hard.
when the punch wears all one does, and its standard in the jewellery
business in the UK, is to set the punch upside down in a leg vice and
swell the face with hammering.
Then clear the swelled punch in the die and off you go again.
Hope this helps.

A lot of the new dies will be in die sets. I do have some open tooling
but if it's on a die set, anybody can set it up and make good parts. I
did leave out all the zeros like Snag said (good catch!) the real sizes
are .030" and .042" steel. I'll have to make gazillions of parts on a
total of 23 dies. They are for a new line of products. I have 9 punch
presses ranging from 20 to 60 ton, most are Blisses. One possibility
if the old dies leave too much burr is to "bump" the punch. Heat it
until it softens and mushroom the face of the punch then clean-up grind
it to a bigger diameter and re-heat treat.
Ahaaa!! now I see your a real pro, with proper tools etc.
Ive a 25 ton Humphies power press for blanking,
a 250 ton hyd coining press,
2 10 tonfly presses and a closed arch 20 ton.This has a 6ft top arm
with 1cwt balls of iron on each end.
A Dangerous piece of kit. Was blanking some cunifer 10 discs and I was
giving it full wack, i slipped and the handle knocked me down i was in
real pain for several weeks. found out it had broken 2 ribs!
for forming hot as well as cold have 3 drop hammers. 112lbs 275 lbs and
a 500lb one. All from pre 1900.
My favorite tools. I just love big hammers.

What do you make?
Twas in 1987 I hada call from a fellow silversmith to say
one of our kind was retiring, all the new stuff was sold and all the heavy
old rubbish was left.
He thought i was the sort of idiot who would like that sort of stuff.
Well, to cut a long story short, it was a complete drop stampers workshop
from 1851. The drop hammer machine weight 1.5 tons the fly presses ,
bolsters dies press tools to match ,catalogues in picture price lists.
well, I just had to have it ,not being sure what to do with it.
I had been showing my jewellery at the Great dorset Steam fair,and thought
Id like to make the brop hammer machine fully portable, take it there and
mint a commemorative plaque for the event at the event.
I didnt stop for 5 days, ran out of blanks ,went home to press out some
more in any brass, copper sheet lying around.
A great success technically artistically and financially.#
Folk just love to see their plaque being made.
That show led to an invite to take it to Germany, to mint there a silver
coin at a castle on the Rhein, and it grewfrom there.
Buckles, buttons, coins,medals ,plaques, and flattened ali beer cans.
got paid to do it!! at a beer festival.
The 1889 Hazelwood & Dent drop hammer is accurate enough to strike coins
in a collar hot. Results as good if not better than a professional
national mint.
Tho of course its a one shot machine., hand placement of cold metal, hot
from an inert gas tmosphere muffle with tongs.
Last product run was hot struck 40th anniversary plaque 2500 off.
in 70/30 brass. 4in by 2.2 in. Coin proof 3D relief quality.

Great fun, and most satisfying work.

How cool! Website with pictures?

Ted,

I was wondering if you ever got down to the Square and Compass at
Worth Matravers for the stone carving week. I've not been myself but I
mentioned you to a blacksmith mate and he seemed interested in what you
did, I sent him your web site link. He often attends the do and makes
tools for the stone masons.

e not been to that meet, but I know most of the applied crafts folk in
this area. The sculptress Mary Spencer Watson was a friend of mine and I
used to drop in to her studio at downshay manor to see her.
She died last year well over the mid 80's.
Ive a stone project here for next summer, ive 2 1700's stone sluices
that need rebuilding on my land so will be doing lots of stone work
myself.There for managing a field watering system on some water meadows.
Thanks for looking.
Ted.
