I have posted a few jpg's of the oil pan design - the draft angles still needed to be added in these 2 shots:
and the mock up we're cutting from MDF:
This will allow a fit check to be done first before committing the the pattern and casting. The mockup should be ready Monday, with fit check following. If all is good then we'll cut the pattern and off to the foundry we go. I'll post more pix, once I have the mock up installed on the vortec.
