All right for all of you who make these radius rods at home without a lathe...........I got a nice shortcut for making radius rods for your steering, brake & clutch linkages.
I use 3/8" rod ends on most of my linkages and tried the ol' drill and tap of a solid piece of aluminum and found it to be a frustrating trying to get a perfectly centered and straight hole drilled into it using a hand drill and a vice. Then you tap it and see crooked the tap is going in due to the wonderful hole you tried to drill straight!
Well...Here was my solution.....
I ordered a 8 foot long length of aluminum round tube from McMaster-Carr.
This tube has a O.D. of .563 and a I.D. of .327
Cut it to your desired length and tap it...No need to drill because the I.D. is perfect for a 3/8-24 tap!
The 8' length has a price of $10.58 +shipping (Dirt cheap......cost me less than $7.00 for shipping)
McMaster-Carr Part Number 1658T47www.MCMASTER.com
I can make a total of 10 radius rods out of a 8' length of this tubing for my racer.
Being a 8' length....plenty left over to make spares to bring to the races!
