Lapping gears....
To me that has always meant running enough laps to break in a chassis. I have heard of a ton of ways to do this. I'm sure I don't come close to knowing all of them so I'll lay out what has worked for me in the past, and some I have tryed that I feel don't work so well.
It can take a lot of laps to "break in" a new T Jet chassis, but there are some ways to shorten the process.
I usally want to start with a few chassis, not nessissary but I like to spin the wheels and feel for a friction free car. Than I rev it up on my track or some power supply for that special sound, (you will know it when you hear it) than throw on a body and see how it runs (find out it's potential).
Once you have a victim, you can apply some type of abrasive to the top gear plate gears to speed up the lapping process.
Here is where it can get sticky LOL. I have heard of everything from toothpaste, to brasso barss polish to rubbing compond. I will touch on these 3.
Toothpaste... is easy to find, cheap, and rinses away with water. You want to find the whiteing type for it's abrasives.
Brasso... a brass polish this one I personaly don't like. Some clame it is thin enough to penitrate the races between the gears and polish them as well. Therein the problem (for me) a huge mess that goes everywhere, and I'm not sure polishing those races does any good anyway!
Rubbing compound... This is the Dogs preferred method,
but I like the light grit type (usally white in color) it workes quicker and is less harmfull than the red type, witch I think overheats the chassis).
Lapping Gears... First run your finger over the gears to feel for burrs, if any remove them with 600 grit sand paper, than I apply a small amount of the abbresive to the gears and run them on the power supply for a few seconds at a time. You will be able to feel the motor get hot don't let it get to hot, stop, touch up the compond on the gear plate, and do a few more seconds. Do 3 or 4 cycles with rubbing compond or a few more with toothpaste. That should do the trick.
Cleaning... after Lapping you will want to clean all the gunk you have just created from you gear plate. with all the methods I have described a fast jet of water works best (from your tap) along with scrubbing with (you guessed it) a toothbrush. I use a fast jet of air from a compresser to finish the job.
Next I oil the chassis, from top to bottom, than run some laps. You should at this point notice some improvment in the smoothness of your chassis. I like to run 50 to 100 laps than clean out the gunk once more.
After all this your chassis should be lapped as well as you need to start with. Of course nothing takes the place of a well run chassis, meaning the more quality lapps you put on, the smoother it will run.
In closing Hey I'm just a T Jet racer, I'm sure there more ways to Lap your gears in, and feel free to send in your comment, or just use the Dogs method to beat me at the next race. Remember the Dog say's anyone who shows up and races is a WINNER!
