with the upgrade race rod offer in the b pro series, i had an extra set of rods for modification...results of a 30 minute project...used dremel to cut, rev tape was enough to protect cut...super glue for ferrules, had to re glue two, so use enough glue...rev has ferrules in two configurations solid & hollow...will ask oracle to make rod bag, & then design bag for sail rolled around rods...g

You talked about "one" extra set of rods for modification. I'm assuming that you cut each of the five rods in half ... yes? If so, then one rod with a ferrule is missing from the pictures ... yes?

Since the object was to make a very short set of travel rods, did you consider not adding a ferrule to both ends of any of the rods? The verticals are obvious ... cut one vertical rod in half and add a ferrule. With the leading edge, you would cut the three rods in half ... two halves will automatically have ferrules. By adding ferrules to one end of three of the rods, you could still reassemble the leading edge by using the same amount of ferrules. However, you would thus avoid the problem of the extra length associated with the double ferruled rod. That would reduce the overall length of the one rod 1 3/4 inches.

With the normal 1.5 set of rods, it's no problem with the center section having two ferrules ... they're already too long to get into a suitcase. But when you're trying to make them as short as "reasonably" possible, avoiding the double ferruled rod looks like an advantage. The leading edge would look like this (the forum removes spaces, so imagine the ferrules glued into the left-hand rod and free to insert into the empty end of the right-hand rod):

[[[[]]]]-- [[[[]]]]-- [[[[]]]]-- [[[[]]]]-- [[[[]]]]-- [[[[]]]]

and the verticals would look like this:

[[[[]]]]-- [[[[]]]]

[[[[]]]]-- [[[[]]]]

That yields five rods cut in half and five ferrules added to the orginal two that were installed in the center rod.

Oh, one additional advantage ... you'd never have to contend with the problem of trying to remove a ferrule that came lose and was pushed in on the double ferruled rod.

Clear or confusing???

Cheers,
Tom

thanks tom...found the extra rod in my workshop...would have missed it on the first flight...you are also right on the ferrule arrangement on the leading edge...my first attempt at travel rods...had to break out the set & follow along with your words, being a visual person...will edit photos soon...thanks for the tips...glenn

[boomzilla]

so, as to not confuse, here is the correct photo, good eye tom...g

Just made my first sets of rods using some Skyshark tubes. I was thinking about using Crazy Glue for the ferrules, but then realized it probably isn't the best tool for the job. It depends upon perfect surface-to-surface contact. Add to that the flexion etc of the rods. Haven't had any long term use, but decided to use a not-as-strong (but probably stronger in real life) contact cement.

BTW, I'm curious. With all those extra ferrule in place, are the rods stiffer?

For a cement to use on the ferrules, I would think a slow set epoxy would be best. Super glue sets way too brittle, and as mentioned, really needs a tight fit to bond right. Just my 2 cents......

Hot glue that way you can get them out if/when they move + if you carry a hot glue stick and a lighter with you , you can make repairs on the field

Gary,

I had planned on using epoxy if when mine moved, but the hot glue sounds like it could be a better idea since it's a little more flexible. The hot glue that archers use to hold the aluminum inserts into fiberglass arrow shafts would seem to be the best. That glue holds well through some tremendous impacts and flexing.

My only concern would be how heat would affect the epoxy that Rev uses to hold the carbon fibers in place. In RC airplane modelling, heat is used to disassemble epoxy joints. A little heat from a heat gun and the epoxy structure will deteriorate such that balsa joints can be safely taken apart. Wonder if Ben would give us some guidance on the use of heat on Rev rods?

Cheers,
Tom

Guidance from Ben? Just give him a call and order a set! He guided my set right to my front door! Luv'em!

The last time I had to get a ferrule out I just held it under the hot tap at home , I think Rev use hot glue anyway

Are the rods numbered, or is it really easy to figure out where they go? That's an awful lot of parts. :?

All rods are the same length... some have a ferrule, some not...
Two (one with/one without) for each upright, the rest for the LE.
If I (being blonde) can figure it out, almost anyone can! Even a man!

The only quirky part is making sure you get the ferrules right (not too many - not too few), just cut and lay 'em out like a Rev frame, then add ferrules accordingly... Assembly is easy, ferrules tell the tale.

John,

Maybe you know the answer on the amount of heat the Rev rods will take before they weaken. I've never had problems with arrow shafts ... just keep applying heat with a heat gun until the hot melt glue softens. Are the Rev shafts comparable?

Also, are the ferrules 3 1/2 inches long?

Cheers,
Tom

3 7/8 inches...g

Thanks Glenn!

Have you thought about converting the double ferruled rod to a single ferrule?

Cheers,
Tom

Jeep, no idea on heat... Never gone there.

[LS Kite Stakes]

The following is only my opinion, so take it with a grain of salt!

The heat the carbon fiber rods can take would be about the same as a hollow fiberglass rod. The resin is the limiting factor, and can probably take @ 150F before it starts to break down. Hot glue is a great suggestion, flexable when hard, can be removed if needed, not much wieght if used sparingly, and fills small gaps well.

Okay, since my bracket sketch might not be clear for us non-blonds, I did a quick power-point slide of what the rods should look like.

Cheers,

have a broken bit of race rod that is perfect length to trim for project...will just need another ferrule...g
