Will do , Greg.

 

And you, or anyone else, doesn't have to specify boiled.

 

I was doing that to all of them way before I started pinning them.

 

Racers only need to specify, if for some reason, they didn't want them boiled.

 

Speaking of boiling, if you boil your own, beware you have to keep an eye on them.

 

Someone just sent me a pic of some they didn't (keep an eye on), probably also had the heat on too high, and the water boiled out.

 

The yellow ones looked just like the awesome roasted potatoes I get from the Chinese buffet in my neighborhood. lol

Just a little info for all.  I used the Red Fox guides on all my chassis for the FNRS at Durham last weekend and did take some good head on wall shots with no problems.  They were not pinned.  I wanted to see if they would hold up for me.  Heaven knows I'm not the driver I use to be and it showed.

[MSwiss]

Fred,

You must be a skillful crasher......or lucky.

 

There were other racers who broke guides at the race you were at.

 

Enough so, since the race ended, I've gotten orders for pinned ones, from 3 of the racers who had podium finishes.

 

PS-were yours at least boiled?

[Fast Freddie]

Don't know Mike I got them from you.  Did you boil them?  I didn't.

[MSwiss]

I went to boiling all of them in early June.

Fred PM'ed me confirming he ordered them June 13th, so they would of been boiled.

 

From my previous, original thread on the new Red Fox guides;

I did go to boiling the latest batch (that came in today).

Just about everyone is using them now at BPR and I have seen a few break, but really it doesn't seem to be any more than in the past few years.  If you take a hit that will break the guide, chances are you're going to have other problems too!  I think at the last Summer Classic race we had maybe  two guides break over 3 days of racing.  Seems reasonable for the amount of racing we got in.

[MSwiss]

Just so there isn't any confusion, I think Tim N. is referring to unpinned Red Fox guides in the above post.

 

I haven't heard of any examples of the pinned ones failing in a race.

 

I've heard of 2 failures, total, on the pinned ones.

 

On one, the post broke during threading, or rethreading, with an old threader.

 

I don't think the pin could be of any value, on one snapped off in a twisting motion.

 

The other was in practice, where the car hit something hard enough, it bent the wire pin about 15 degrees, before it broke in two.

 

As far as last week, I didn't hear of any at the Tom Thumb, Jim Nolen Memorial Enduro.

 

Two or three teams, had my pinned ones, on their cars.

 

One team mentioned getting ridered into the Deadman, having a clip and a braid, knocked out, but the flag survived.

 

At the USRA Wing Nats, Jason Hooper was runner-up in both One Motor Box, and G27 Lite, using my pinned ones.

 

But he said there wasn't any breakage, that he noticed, with any.

 

Maybe the lighter cars aren't that hard on them.

 

I know I haven't seen any here, in our Group F and FK12 wing races, and most are unpinned.

[Tim Neja]

Sorry Mike,  correct---un pinned stock guides.  We have found like everyone else, they DO seem to be faster!!  I haven't seen any of Mike's pinned guides yet, but that has to be a great  upgrade!!

[MSwiss]

It was a diametrical opposite for RF guides, this past weekend.

 

At one Retro race, on a fast Hillclimb, no reports of broken guides.

 

In another race, with Retro and flexi cars, on a fast Gerding King, reports of at least 7 broken guides (AFAIK, all unpinned).

 

Some racers may of noticed, as of late, that they are receiving guides from me, with .047" wire pinning, instead of .039".

 

I've been on a hot streak, with my drilling mojo, so in an attempt to offer the best product I can, I've been stuffing in the biggest wire, possible/practical, for me to do.

[tonyp]

What about the extra weight? Lol.

I took 2 major front end shots this past weekend at haven raceway. Both hits were square hits right up front guide showed no signs of damage.

[olescratch]

Exactly what/why boil?  Does it make them harder in some way, or less brittle?

[Tim Neja]

Boiling helps make them less brittle.  Helps avoid breaking them.

[bbr]

Water absorbed by nylon, makes it more flexible and releaves some of the molding stress
But over time the water will dispate, so reboiling is required

Pinning the guide prevents guide shalf from flexing too much during a hard impact. Any material will only flex so much before it will fail

I've tried to get that point across, about reboiling being a real good idea, in another thread, here on Slotblog.

 

http://slotblog.net/...hat-i-would-do/

 

But an "expert", on FB, has insisted it's not necessary to reboil, or pin.

 

The same expert, who broke two guides over the weekend, in both a Retro and Flexi car.

 

I just checked a number of guides, I boiled for about 30 minutes, about 2 1/2 weeks ago.

 

There isn't any way they are nearly as flexible, as they were, right after boiling, or the few days, to a week, afterwards.

Thanks a lot for your feedback, Willy.

 

I don't have the equipment to measure how much stronger they are, so it's good to see they are surviving hard hits.

 

If they weren't useful, providing an extra measure of safety, in a crash, I'd rather be devoting my time, to other projects.

No problem. I was a little uneasy having them on my car at retro palozza not knowing if they would last because i didnt boil or pin my first few i got..after thid past weekend i think seeing them withstand the 2 hits i had makes me feek alot better about boiling and pinning them. Thanks.

[Tim Wilkins]

Mike,

 

I assume the pinned ones can be cut down even further than when they first arrive from you without damaging the integrity of the guide flag?

[MSwiss]

A very good question.

 

Yes, it can be cut down.

 

But I would leave it as long as possible.

 

When I've tested them, a couple times, and hit them with a hammer, harder each time, until the the post breaks, the pin has stayed in the bottom part of the guide (blade and base), but comes out of the post.

 

For (maybe) a tiny bit more strength, you could cut the plastic part of the post, but leave the pin full length.

 

You could then solder an .047"-050" Sonic keeper on the protruding wire, and then trim the excess wire.

 

Of course, all the above would be predicated by how much body clearance you have.

Have been using Red Fox guides -boiled and pinned- by Chicagoland in our summer racing program. On the red lane the other night on the King - using a 4" flexi, s16d, RF pinned guide- my car whipped around the lead-on and was full tilt down the straight when the car slammed into car parked in my red lane. (Ever have that happen where you look left down the track but guys are leaning over so far you can't see your lane???) Anyway, I whacked the parked car full tilt. Result was a loud crack with no damage to my car - pinned guide intact - with the other car hit so hard it knocked the motor lose from the chassis.

That's been my experience with these RF pinned guides so far. I've had plenty of crashes but no guide failures. So far, so good.

[Mark Crowley]

Does anyone have any experience on just boiling and not pinning the guides?

Mrk

[Fast Freddie]

Mark, read posts #83,84, and 87.  You'll get your answer.

I just saw a confusing post on FB, citing using metric nuts for Red Fox guides, to avoid breakage.
 
I guess if the post was threaded, using a metric threader, that's what you would use.
 
To be clear, any pre-threaded guides, pinned or unpinned, purchased from me, were threaded, using the same GT1, (non-Metric) 10-32 threader.
 
Use nylon 10-32 nuts, either stock, standard height ones, or the trimmed ones shown in the below photo.
 
If you want to use a metal one, my locals are having great luck with the new JK round aluminum nuts.
 
Do NOT use the Koford M615 brass.
 
It is much too tight a fit on the Red Fox guide.

 

My trimmed nylon 10-32 nuts, on a nylon 10-32 bolt, threaded all the way into my 10-32 threader.
