Hi All
Sorry to resurrect this very old thread. I’m starting to get ready to build my special engine. It has a billet 1 1/2” crank and Nippy rods. The crank, flywheel, clutch etc are with the Machinists to be dynamically balanced. I’ve now set up a rig to balance the con rods similar to that shown earlier in the thread. My kitchen scales (well protected with cling film) read down to 1 gram.
My little end readings (holding the big ends in the rig) are all within 2 grams. The rods with big end caps (but minus the bolts and nuts) vary by 12 grams.
Question 1 How close should I get the readings (to within a gram??)
Question 2 Where is the best place on Nippy rods to take material from?
Cheers
Howard
