'396, another question. I ordered a sample kit of Ren Board form Freeman, looking at their site, the number of different grades made it non obvious which one to get. As material goes, it's cheaper than machinable wax, but still a sizable investment for a whole sheet.Will you use the Ren Board you machined directly as a pattern, or make a rubber mold and use Repro castable urethane? It seems ramming sand around those small fins may cause some breakage. Also, what do you finish the Ren Board with?Maury
Hey Steve,Why not mount that to a match plate? It will support the pattern and runner and make the whole thing a very strongAll a match plate is , is a piece of heavy plywood. Pattern and runners on one side.....filler spout on the other.......makes it easier to take from the mold too....
That's bad luck, Steve. The curse of Gotham? Any point in making it at 90-95% full size?Hugh.
After reading the story on the deezil it makes me want to build one and see if it runs and for how long. Would make an interesting contest too lol.
