Looking at the 10ER accessory catalog that arbor is basically the same as the current arbor but the catalog says the thick washer is 3/4". Does anyone have a known 10ER arbor and does it have a key way. It is hard to tell from the picture in the catalog but using a magnifying glass it looks like it has a key way. However, the catalog is dated 1953, the end of 10ER production. Maybe the first/early arbor had no key way.
This is the arbor that came with my 10ER, it is what I use with my saw blade.
Total length 3 1/8, shaft length 1 5/8, keyed shaft and washer.
and with the blade mounted.
Interesting! The 1953 accessory catalog lists a 3/4" spacer and TWO
3/16" spacers. The two 3/16" spacers are clearly visible in the picture of the arbor.
To quote..."The collars, one 3/4" thick and two 3/16" thick, are machined and counterbored to assure clamping fit."
Quite obviously your arbor will not accommodate a second thin spacer. This tells me there are at least two different arbors for the 10ER. So again maybe the very first ones did not have a key way.
It would seem they changed the design a few times. I was just looking at the 10e preliminary manual and it describes the saw arbor as having two threaded washers.
The '52 catalog description is the same as in '53 that you quoted
The '54 catalog only shows arbors in the Mk5 section but under saw blades in the 10er section it says to use the 5/8 arbor , this is the first one that mentions the keyed washer, but the picture is the same as previous years.
Something to take into account is that they did not have separate saw and accessory arbors, so for saw blades you would use the 3/4 washer and one 3/16 washer, and for thicker accessories (wire/ buffing/ grinding wheels etc) you would use the two 3/16 only, one suspects that the unused one would get lost over the years.
Perhaps the keyed washer was included all along and just wasn't mentioned in the earlier catalogs,(they don't mention the nut either).
