Rd Alpha Max Posted January 17, 2012 Author Report Share Posted January 17, 2012 yeah I tried the Torres. i wanted the port bigger though. is there any way it could be bigger? And what do you mean by 3 common walls?

certifiednut Posted January 17, 2012 Report Share Posted January 17, 2012 its about 3/4 of the way down on the first page of the torres calc. thread, it just means it is on an end or top or bottom and goes all the way across, also there is a box on the calc. that asks how many common walls. i plugged some numbers in there and with that small of a box it looks like any bigger port and you need a port about a mile long. these orphans aren't going to feast on themselves Link to comment Share on other sites More sharing options...
