Hello, team,

 

It's is my first attempt to build an IRRA Stock Car chassis. Can you please point my mistakes, and show me I can improve my skills.

Thank you.

Looks great. My suggestion is to brace the axle tubes and bracket.

A little less solder would keep it cleaner. Use lot's of acid flux-- just enough solder to spread after the heat is applied.  Then keep cleaning after soldering.  Nice job--- looks good!


She's real fine, my 409!!!

Nice job Daniel. Like Mike said, definitely brace the axle tunes. Once you have tried it if you find you need more weight add a floating center weight. I usually use .016 brass for this so I can add as little or as much weight is needed.
A motor is only as fast as the chassis it's in.

It looks like there were not any axle tubes originally and then you added them? Did you start with a long tube going across and then cut it? You have to cut the tubes almost flush with the inside of the bracket. Here you can see some bracing..IMG_20130901_205018_085.jpg

Yes, I started with a long tube, soldered and cut,now I’m going to trim, thank you for your suggestion I’m going to do the same bracing as your chassis.
I really appreciated your help and time.

For the bracket, make a square u and use it to brace the inside. The center flat of the u should go against the bottom of the bracket by the motor and the two ends go over the top of the tubes on the inside. 055 is a good compromise for this. Also use some 047 to make a brace on each upright in the front to keep them from bending in a side wall hit. Put the brace behind the Axle. And if you did not already, add a color on each end of the Axle to give more surface area to solder it to the uprights in the front.
It looks good, practice and repairs will make your next ones look better.
