Continuation of wobbly Wheels and untuned bores

Chrisw Saturday, 1/18/2020

Afternoon speedsters something that came across my mind. When we rip and race are cars down the track I remember what Chris Raab said about your car goes down the track at 11 thousand RPMs. I was thinking about this as I was going through Redline Derbies archives. And please do not get mad at me it's just things that pop into my head, but if we race these cars with no lube on the axles orin the bores of the wheels , couldn't that be one of the major problems of wobbly Wheels and untrue boars? Because we all here understand the ways of physics potential energy, kinetic energy, and friction and we know what friction equals to heat. Rip and race on a dry metal axle to a dry plastic wheel will bring a lot of heat and friction which would most likely mess up the boar right???

I don't think the wheel to axel contact would create enough kelivins to cause warping.

Back to the archives for me. Love the knowledge

Really not sure how it would create enough heat to ruin the bore. The cars are not on the track long enough,IMO, to creat the kind of heat to cause warping. When you look at some of the longer tracks out there races only last between 2 to 4 seconds. My track is scale 1/4 mile and even crappy mainlines are running in the high 2 second range. I guess if you were running a 400 gram mod down a really long track then I could see a bit of heat produced. IDK

Ok thank you  guys . It was the thought that nothing in life is perfect. You can take time out to make things to your liking , but it takes one little overlook to turn it into a nightmare.

These wheels do  'warm up' a little when they are run...and it will, usually, make them run a little quicker. If  you were to take a car right from a race and run it against car that has been sitting, that car that just raced will have an unfair advantage. Likewise, when you watch cars run, sometimes a car will get beat in the first race and simply smoke the other car in the next two races...that car's wheels needed to 'warm up' a little in order to run well.

Now, if the wheel was spinning fast enough to deform the hole, the wheel would, more than likely, lock up on the axle. To show this, hold a dremel sanding drum (without any sandpaper on it...just the rubber drum) against a wheel and crank your dremel all the way up...the wheel won't last long before it melts and seizes up. 

These wheels are pretty close to the edge...12,000 rpm, they are okay...somewhere around 15-20,000 and they fail.

Thank you for elaborate 72_chevy_C10 . that's a real interesting subject , that's something that I would want to dig into more . I must say I appreciate you guys teaching . Me coming 1/32 scale Slot Car Racing 2 gravity propelled Hot Wheel cars it's a different type of evil let's say that but I'm learning a lot from your archives from your videos and League of speed you just created a monster with the wheel situation it's like now all the wheels I have I just spin them to see if I can hear any imperfections "OH BOY" hopefully when I race you guys I will be competition.

  • Main thing here Chris is your enjoying the site...I try to get as many people to join RLD and find out what it's about...there is no other place like RLD...Facebook pages and groups just can compete...fun...but basically just chatter...no substance...so, love to see some one catch on about what this place is all about — LeagueofSpeed
  • I went the other way, Hot Wheels racing to slot cars. I don't really do custom slots, just basic "fun" slots but I've added weight some cars to see what happens. It's fun to experiment with it. — redlinederby
  • Take the magnets out then add weight just remember around the turns you got to finesse it — Chrisw
  • I raced 1:64, 1:32 and 1:24 slot cars starting about age 6 until I was 22ish. When my last 124 track closed. Between 14 and 21 I raced anywhere from Chicago to Indianapolis durning that time we built 1:1 dirt track cars for my dad, myself, uncle and friends. It wasn't until my 30s before I got into gravity racing hot wheels. I'm 36 now and it's very fun and very frustrating. — NDeavers80
