chasing the threads after a cylinder replate
Posted: 03:40 pm Nov 20 2016
Regarding cylinder replating:
I saw this suggestion on Thumper Talk
"if you have a cylinder replated, run a chase or a bottom tap through all the holes. the cleaning process they use leaves a lot of burs in the aluminum threads as the contaminants leach out. there is enough to screw up the threads on the smaller bolts, and you will get very inaccurate torque readings"
For you guys who have had replating done, have you done this? If so, what did you use to chase the threads (a tap, or some other method)?
If not, would washing the cylinder then blowing compressed air into the holes work instead?
I worry about running a tap through aluminum holes, then because it could end up messing up the threads even worse.
