The normal method of making suspension links is to use a pillar drill, or drill press, requiring careful positioning of aluminium rod so you can drill the end, then you have to tap the hole using a bottom tap which isn’t the easiest thing to do.
Instead I use commonly available, fairly cheap aluminium and brass tube from B&Q, and M3 studding which is available from most model engineering suppliers.
I’ll assume you can work out the length yourself and go straight into making the links.
Cut the brass and aluminium tube to equal lengths, I like to use a small pipe cutter as it gaurantees a straight cut.
Press the brass into the aluminium tube, since the tollarances on the cheap aluminium tubes aren’t great the brass could be a very tight fit, to make it easier put the brass in the fridge for 10 mins, then gently heat up the aluminium, you only heed to heat it a little, just to the point you can’t touch it.
Cut the M3 studding to length, for the Axial ball ends on the SCX10 6mm of thread is needed, to cut the studding 12mm longer than the tubes.
Fit the ball ends and attach the finished links to your truck.
So there you go, they look the part, are super strong and you can make a set in under an hour, what more could you want?..
