Ok guys, Ive ben getting some friendly advice from TM, so ive been starting to re-do the arm pieces.
Right since ive last been here ive been working on some advice from anh trooper
I managed to save the clay from the previous mold and i carved off the ladder section. I also made a few adjustments and took off the edging strips.
I then Made a moldcase of the front arm under piece.
Then once i had the mold cases i adjusted inside the arm piece with the lladder section by adding some clay. One remolded the ladder section will have "dissapeared"
The plaster mix was made by sifting plaster through my fingers into the water. Its added to the point when little islands appear. I leave it for 5 minutes before a quick mix then pour into the molds
Then ive redone the ladder section with 12 bits on the left arm piece.
I will do the right arm piece ladder section after work tomorrow.
Then its onto making molds again.
cheers
