Will we get a copy of that explanation here at DT?

Looks like your kids got what they asked for. Those cupcakes look good enough to eat... but I don't care for lead filling, prefer icing.

Stan, While I don't think many have "real" world experience with what your asking...(nor do I).... You will likely get lots of opinions mostly geared toward "X" grit = "X" grit, what difference does it make which direction it is accomplished? Wish I had a better microsc...

Awana is what we do. Last year i did the novus thing but i think we did much better thus year with micro polish. As you know they are softer plastic so slow speeds seem to work best. I did a quick and dirty test of the two on my son's miroscope plastic slides and i ended up with better finish on mic...

So with the changes you are suggesting, that's not a $50 purchase anymore. You should walk away and send me his number. :-) seriously though, if you race on aluminum, your test results might not be valid. Well on that note I decided to buy it. picking it up tomorrow. I figure the kids could easily ...

...Bent new axles at about 2.5 degrees, reinstalled with similar gap. Lubricated. Verified rear end alignment, and made 3 more runs. Times better, and all within 0.001 seconds of each other. Tweaked rear alignment per track times, but could not improve the times. Replaced the lifted wheel and axle ...

That's cool! I assumed it was for all show till you said the tread didn't continue under the wheel and I looked at the pic closer.

I think I prefer the mark in direction of bend (don't use a press... trying to work toward not having to bend at all). It helps me keep straight which way the bend is and that what effect turning the axle "should" have on the alignment. If you don't get the desired effect then something el...

What do you think? :thinking: Pass or jump on it? Track 40' in 2 rigid lengths of 20'. I'd need to add timer and automate the start gate which I was going to do anyway if I built a track. I'd also need to add a stop section. The only thing holding me back is that's it's not your typical slope-curve-...

Wow! Love the detail on the fenders. Looking forward to seeing more pics as you go.

I think everyone is right "On Topic". Seth is actually asking, "If I sand and polish my axles more will my car go faster?" That's a great question. Sometime ago FS suggested a test on axles be done and I intend to do that. I need to work in the warm summer months. My track is in...

Chromegsx, I had no idea they were different scales. Thank for clarifying, Seth Seth, It was my pleasure... but thanks go to this forum for providing a search feature in which I stumbled upon this knowledge some how. :thumbup: .... I simply wonder if we are helping or hurting ourselves with all thi...

Curious... Is it just the bad run-out that causes these wheels to be "junk" or is there more about them that makes you want to throw 'em out? I might be looking for some donor wheels in the near future for testing removing run-out without a lathe. Also what does bore I.D. on the small side...

When people talk about 4000+ grit they are usually refering to micro surface grading method which is different than normal (ANSI OR CAMI USA) Check out microsurface's conversion chart . 4000 micro surface is similar to normal 1500. They are not the same grading system. Try to compare micron levels f...

We did similar testing on test and tune night. and ended up a full car ahead of last year. New car won every time by half a car or more depending on staging. Once my son wanted to run the new one backwards... I cringed and said "go ahead." I didn't want to spoil his fun and discovery. The ...
