Hey Gang,
I took my piston rod assemblies to our local market after hours and got the first weigh in .
#1 1420 g
#2 1430 g
#3 1440 g
#4 1410 g

looking at the #3( the heaviest ) the casting marks were rough looking
then looking at #4 ( the lightest)) it was smooth with no casting marks

I used our air die grinder with a tungston burr and now have
#1 1410
#2 1415
#3 1417
#4 1410
I'll do a little more grinding and
Tomorrow I'm going back and weigh them again

does 30 g seem like a lot of difference between two rods?
I'm shooting for all the same
hank
