Pack Race - mixed results

[cozybldr]

Things were going well, and then the back wheel sucked up CA glue uphill into the bore. I really hate losing a DD4H wheel like that. The car had been doing 2.57 consistently until that point. I grabbed the best wheel off my Family division car and installed it. The car slowed down to 2.588-2.62 range. This is for a 35' Besttrack.

That was last night at 7:30 p.m. No possible way to get John to send a me new wheel in time for today. Hope and pray it is good enough. The wheel was one I had done on my lathe and prepped. My son took the Wolf Den 1st place easily. The closest car was a full car length behind him. He missed the overall Pack Speed trophy by .04 seconds over 6 runs. Not too bad, but somewhat disappointing. Overall, it was a great Derby for the Pack.

Thanks gang! All I have to do now is get Carolina or DD4H to help me retune the car and point out my mistakes. The rules force all 4 wheels rolling. Just as a reference point, we ran a 2.70 average last year at our best.

Why did you have CA glue even close to a wheel?

 

[MBL Racing]

My handle will tell you what I think about having glue in the same room with our car./images/boards/smilies/smile.gif
Great times however in what would seem to be an advanced pack as far as PWD goes.

 

[Old Geeezer]

Kinser you took the words out of my mouth. You don't even want CA in the same room after you put the wheels on a car.

Ok, what do you guys use to hold the axles in? That particular one was sliding out rather easily.

 

[DNA RACING]

in a drilled hole, or in a slot?
we dont use anything.

 

[cozybldr]

drilled hole with a slot cut in. It was loose enough to wiggle out on its own down the track.

 

[Kinser Racing]

A little elmers glue on the hole and then slide an extra axle in. Pull the axle after it dries and set it up with the good wheel and axle. /images/boards/smilies/smile.gif

 

[DNA RACING]

drilled with a #43 bit?
using .093 axles?

 

[cozybldr]

Yes to the 93G and the 43 bit, with the slot cut out after the drilling.

Kinser, you are brilliant. I should have used the white glue method and spare axle. I feel silly now to have not thought of that. I am having a Doh! moment now.

Thanks!

Live and learn.

It happens man! Just ask. /images/boards/smilies/crazy.gif

Look at how far I have come in the year. 2.70 with stock axles and Derby Worx tools to 2.57 on the test runs with the Block, 93Gs, Nitro wheels and fenders. I am beginning to think I need to start building Stockers for the National Races to get me to the next level.

 

[Kinser Racing]

Yes, you do! /images/boards/smilies/biggrin.gif

Rick, we have all done the same things! I would be here all night listing all the goofy mistakes I have made. I will get you straight no worries.

I make most my cars with Cubs, both Grandsons and just helping kids with limited access to either tools or parents who can help. I modify the good advice here to try to make it easy for a Cub to do all by himself. I have no blazing speed to say my method is better or even just as good, just usually simpler for a Cub. I set the drill press up with a 2.30mm ( 0.91") bit and let the Cub drill the holes. A great tip from Cam-Car was to use dental floss in the hole if the axle is loose. I drill the holes all the way through the car ( even the canted back axles). Yes, I know this makes a sloppier axle hole, but when you can see daylight through the hole, you know it was a straight drill and I tell the Cub he will have a fast car because the axles will be straight.. Then the Cub can thread a few loops of Teflon coated dental floss through the axle holes, tie it and use a bit of scotch tape to hold it to the bottom of the car. This lets you get a nice snug fit without ever bending an axle ( used to happen with older thinner grooved axles in cheap Basswood bodies like Pine-car) Now the FDW gets to run on a Teflon coating if it does touch the side of the car.The FDW gets banged a lot on old wood tracks, so we put in extra bits of floss to make it super tight. It still allows for rotation from the axle pliers, but will withstand normal wear and tear I was amazed to find that after flying off the track 4 times at the Pack race, the car was still in perfect alignment.. Even though a few weeks went by before the District race, the car never slowed down, so we did not re-prep and won the District race and set a new track record for Denton-Cook counties..

[font="times new roman, times, serif"]That is realy cool stuff...I hope that if and when I get to have grand kids I will be able to help them with this kind of stuff...I just hope they like mechanical things like cars and stuff...Who knows there might not be any kind of cars that far in the future...Ive got at least 15 years to go.(I hope)![/font]

Thanks for the Dental Floss tip, both Chief and Cam Car.
I solves a problem for me.

That is what is amazing about this group of builders. We start off the thread in one direction and all of a sudden different tips come out that benefit us all.

Thanks!

John,
I placed the order for the Legend Car Carrier yesterday.

Thanks again!
