Yes sanding the rings with 600 grit does make a big difference - i've been doing this for a long time. So far i would say that is the single biggest improvement i have done to diffs.

Might try some CA on them, i don't know - i have a brand new diff sitting on my bench at this moment..........hmm

I used a pair of straight body scissors and dremeled the tips into a point that will fit the c-clips. They suck for body scissors now but you can still cut other stuff with the back of the blade. They work really well for removing c-clips though.

I have a pair of cheap round nose pliers that I got from my local hardware store for about a dollar and they work great. I dont know what its like down under but here most hardware stores have a cheap tool section take a look there maybe.

I bought an inexpensive circlip pliers from Dick Smith Electronics.

I had to file a small portion off the tips to fit the schumacher circlip hole size, but they work perfectly and cost me just a few bucks

hey do you guys seal up your batteryholder with ca?? i know your ment to sand and then putdrops of super glue on the chassis but do u guys do it to the battery tray and strap??

King-G

I personally dont bother C.A any of my chassis edges..I sand them round, and use wed / dry fine grit to give a glass like finish to the edges.
I havent had a problem with delaminating chassis in the time Ive raced.
I figure a hit hard enough to delaminate a rounded edge would still damage one with a thin layer of C.A.

I do file the edges of the battery slots slightly to prevent it cutting the cells shrinkwrap.

You'll want to get the best iron you can get with the widest tip you can get. An adjustable temp iron like the Hakko 936 that I use is nice but not a necessity. I used a Hakko 80 watt iron for a long time. It's cheap, comes with a big wide tip that's perfect for doing batteries. The key when doing batteries is to only have the tip on the cell for 1-2 seconds. You don't want to heat up the cells too much or you can damage them.

BATT_MAN

For battery assembly you should get a 100W 700'F (or an 80 Watt like Jon said) soldering iron with a 1/4 tip. The WELLER 100P is a very goood sldering iron to do packs. You can do most connections in less than 2 seconds.

For eveything else, any good station will do.
You do not want to use a lowwattage station to build batteries unless you are very good at soldering. The longest time you want to keep an iron on as battery tab is 5 seconds. After that you are asking for trouble.

You do not need more than 50W for general soldering like wires to the ESC and to the motor.

60/40 solder melta at around 420'F and Silver solder at around 470'F
What you need for battery/tab soldering is an iron with enough POWER not heat.

Marcos has a hot set-up that he ran this past weekend.
Shot him over a P.M. and I'm sure he will help you out.
