Fellow Wakegarage guys, I appreciate the positive comments.
jtryon, Yes, I did make them for this project only. My buddy and I actually made 2 sets of wood dies, one set for the 3” oval tube I did not use, and another for the 3 1/2” oval tube I did use. A set consists of: one round and one v-shaped oval (last photo above). I threw both 3” oval dies away already. I gave the 3 1/2” v-shaped oval die to a friend, because he was going to possibly do a similar down pipe for a Moomba. Do you just need the dies? Or a formed down pipe?
