My vintage Legare 400 came with a 54 and a 72 slot cylinder and a single 36 slot ribber dial.
Obviously when the regular (vintage) approach was to use a ribber with half the slots of the used cylinder, the 36 slot ribber goes with the 72 slot cylinder - HOWEVER - you can ALSO use that same 36 slot ribber dial with the 54 slot cylinder.
Are you as mathematically confused as I am with this? (It’s ok - an easier approach is simply to align the parts and see the common slot alignments - OR review the ribber/cylinder reference chart(s) that sometimes were printed in the manuals)
There was a time I used to worry about exactly which combinations matched mathematically with regards to cylinders and ribbers. Too much thinking!
The photo above shows that indeed they function together. When using a 1x1 rib pattern it mathematically works. However when we go to the 1x3 (1 ribber/3 cylinder) setup you will find that 3 does not divide evenly into 54 - which is OK. Fudge it. I won’t tell and your sock owner won’t know unless they peer way too closely to the sock.
