I had the same jointer, and never used a jig and never made any kind of reference marks (or felt the need to)... just used a dial indicator. The manual describes how to do it with a straight edge if you don’t have the indicator.


PS: How were you able to determine the age of the machine? From 1937, there were no noticeable changes I am aware of until around 1949 when the fence angle pre-set arrangement was changed. My 1954 model was fortunate enough to have the date stamped on the bottom of the infeed table.

easiest way to set straight jointer knives is with a good straight edge. I always used the base from my combination square when I had a straight knife jointer. set the straightedge on the outfield table, spin the head until the knife just barely touches the straight edge. do one side of the blade, then repeat for the other side. Takes some trial and error but with practice you can set knives in about 15 minutes. be sure to recheck after you tighten the wedge bolts, sometimes things will shift.

No need to be shy about changing knifes. I hate to say this but you tube is a great resource for this.
My recommending would be the stick drag method it’s so easy.
The method I use is a Dial indicator for very precise knife sets.
And the stick drag method that’s fast and easy but not as precise for me.
Good luck, love old jointers.
