Reducing
a design |
Initial
production concept was to manufacture a 3d pantograph
with cycle powered dremel attachment, copying in part
how modern coin dies are manufactured. |
|
| |
|
|
|
Reused
materials were sourced
|
 |
|
|
|
|
The
Pantograph was manufactured |
 |
| |
|
|
| |
But
the tolerances of manufacture - even while still 2d
- were not good enough to ensure accurate reduction.
- FAIL
|

|
|
| Plan
for coin die blank |
Working directly on 1:1 scale was adopted. |

|
|
| Coin
Die Blank |
Graver's
tools were bought through ebay, judged a reasonable
resource cost for retooling
|
 |
| |
|
|
| |
The
coin die blank was carved in the workshop
|
 |
| |
|
|
| |
A
number of blanks were completed on 1:1 scale directly
into plaster. |

The
next stages will require:
- manufacture
of waste oil blast
furnace
- casting
of die in iron
- researching
pressure or impact pressing
- resolving
possible legal issues of overstriking two pence
pieces.
- striking
coins
