You can make a very good traveler system relatively inexpensive by just riveting a bullet block on each front corner casting and one small cam cleat [with wedge] just a few inches from the bullet block. Use hog clips to attach control line from your combination traveler and cleat so that the stop pin is always up. Then attach a piece of bungee cord from the port and starboard jib traveler cleat comb. so the cars will return to the inboard end of track except when you cleat the traveler car out with your control line. Welcome to A Fleet book has a few different options. Contact me directly and I can scan the page from the book.
