I think trying it with a bunch of washers is a little sketchy.
Definately get the jig right for your OLN before proceeding. Seems that means taking a jig bit to your machinist friend for a tuneup. That will give you a much better result Later you could have him make a few spacers for the other OLNs if you need them then. Having to be twiddling your wheels or mod'ing the frame afterwards to make up for not being jigged up correctly seems to be an exercise in futility and a poor precedence for going forward...(apologies in advance for slightly offending those posters who suggested such).
