We are rail riding using the new derbyworx tool, 2.5 deg on back, 1.5 in front. The problem is we can't get the rear wheels to stop drifting in towards the car body when it is rolled backwards. We have rotated the axels all the way around with no luck ! When
rolled forward the wheels drift nicely to the axel hub and the front
moves to the rail well also. What to do ?
The race is this Saturday your help is greatly appreciated !

Either redrill your holes or put more bend in the axles( light tap of the hammer). Scott Beakerboys |

We put the axels back into the rr tool and gave it another few
taps, now we have loose axel slots from all the "dialing" we did.
What should we do now , we have to use the slots. ??

If you have an extra set of raw axles, place them in the slot and epoxy them in place. Just fill the slot with a two part epoxy, I like the 5 minute stuff, but you may want a longer cure time, then place the raw axles in place where you want them. Coat the axle with either graphite or wd 40 so that when the epoxy dries, you will be able to pull the axles out. You want any slop at the top of the slot filled in with epoxy and when it dries and you remove the axles, make sure the surface where the wheel hub makes contact is smooth, you may have to sand a little. You will then have good strong axle "hole" in the stock slots. After you dial in your alignment, drill a couple of real small (1/16) holes perpendicular into the epoxy that you put in the slots and a few drops of super glue will hold them nicely. Check your rules first though and make sure that filling the axle slots is allowed. Scott Beakerboys |

I like to once i have everything dialed in and where i want the axles and my alignment.
I drill a small whole if using drilled axles slots, towards the end of the axle end (not the axle head). right onto the axle. a little bit, then i take some two part epoxy and a tooth pick and apply to the whole and also onto the end of the axle in the wood.
hope you are following that.
I have also taken a dremel and just a small line in the wood and into the end of the axle and apply two part epoxy into the line i made with dremel disk.
holds them nicely and is away from the axle head and wheel.
This would only help if the whole is loose and not out of round.
holds them in place just fine. I also had had to remove the axle and with the axle puller was able to break free the axle with out damage. But only recommend that for emergency must do's.

One thing that has worked well for us in cases like this is to apply a tiny bit of water to the slot using a toothpick or and old toothbrush. This causes the wood to expand and tightens up the axle/slot interface. Once the axle is snug and you've retuned your alignment, gluing your axles in place like the other fellas mentioned is a very good idea. Steve B. |

There are many ways to tightened a drilled axle hole. All of the ones mentioned earlier by Scott, Speedie, and Steve are all good. Here are a couple more that have worked for me-
1. Cut a small square of saran wrap and put it over the hole before you insert the axle. It will fill the loose space and make turning the axle for "tuning" better.
2. Break off the end off a toothpick and put the pointed end in the hole- use a pin vice to push it in and gently ream with a smaller drill bit (you could probably wet the toothpick also)

Hi Guys,
Just want to say a Big Thank You !!
We tried the water trick and it worked. We were able to get
the rear wheels aligned on both the forward and rearward
roll, we put a drop of gel super glue on each axel and all is well.
My boy is very relieved !
Thanks again for the great ideas.
Good luck to all you on your races,
Ali B.

I know a little off interest. But I would caution on the super glue or gel.
I have seen the vapor from it, get into the wheel bore, it can cause residue and hazziness on the axle and wheel bore.
leaving a light, sticky vaporish residue.
Heres a not to so funny, hard lessoned learned.
My daughter, got a psp, you buy the umd mini disk games. well before she knew what she was doing. she took all the umd cases apart that held the cd. not knowing the case was part of what you needed to insert into the psp.
She then put them back together, but had broke the plastic welds that hold them together. she then took and dapped a little super glue on to those areas.
Well the vapor got onto the disks and ruined them. it could not be fixed.
This was done to 10 brand new $30 + dollar games.
rule 2- never let young teen run to room after buying electronice and leave them alone, asuming that they know what they are doing.
