My husband is doing the change over for the fixed voltage on 027 track switches and he is following what Ray L. Plummer had put in Feb. issue of Classic to trains page 61.what he hid was drill out pivits on F-G and H , and along with the casting stud rivit as direction showed on the page,the question is how do you reconnect the frog point when rivit has been driled out,Please help us out
Thank You
