Very good !
I think this is the first time i have seen model board used on a forum build, guesing at the colour i'd say it's 540 > 651 grade ?
I fancy trying the high end grade stuff but the bank manager .. he say No!
Do you have any experience of it.. does it need much seeling prior to casting?
Neil, i recon you might know the answer aswell?
Good job !
Regards,
Kim
