Hi All,
Reading some of GR's articles and would like to know if anyone has any more info on checking and straightening smallbore conrods. GR had mad a jig for checking but I can't figure out the ins and outs of how it works. Also planning to machine some of the sides of the big ends to lighten and balance the rods.
Cheers

I have used that jig of Graham's many times. It's a precision setup.
The distance is measured as shown then the rod and pins assembly flipped over and measured again.
Twist is apparent if the assembly can be rocked on the 2 fixed blades underneath.
If bent, he has a Vee jig used in the vyce.

Just send your rods to Graham...;)
