Silicone moulding of the helmet part 1
Basically started to make a mould of the helmet so I can replicate the original and produce many more iron soldiers lol.
It’s a long winded process but worth it if you do it right as I said once it’s finished I can pour liquid plastic into the mould and make many more.
To start off with you need to divide the helmet by using a blank or board which needs a section cutting away so the helmet slides into the gap, then using clay build up a wall or barrier so one half of the helmet is sealed.
Then create a keyed edge, so make holes so when you do the other side it locks into place as a reference point so when you take it apart and put it back together you always have those points to locate the two halves back into the correct position again.
Think of the clay wall as a moat or channel so when you pour the silicone in it the wall stops it dripping everywhere.
Then a thin coat of silicone, followed by 2/3 thick coats and using a ice cube rack make cubes as key points for the rigid mother mould to lock to. Basically following the xrobots.co.uk method.
Still waiting the plaster bandages to dry which is worrying as it still damp after a day and I really want to get fibreglass on top to make it stronger then I can do the other side.
Long and boring but hopefully get it done for next weekend.
Not much else really as it’s getting colder finding it harder to stay outside longer, but some pics in part 2.
Slow and steady wins the race as a friend once said.
