I use the tech manual from hereThis Sunday is 6139 day.
I have 5 customer's ones to finish and a similar number of mine to do and I'm going to put other work aside and rip into them.
I've even jeweled my customer's one barrel arbor holes (you know how they wear:undecided
I did a 6139 and a 6138 last year but I'm not confident at them and would like some extra info - especially where to grease them etc.
