I have an 1950's Rockwell "Heavy-Duty Shaper". Most of the cutters I
want to use are only available with 1-1/4" bore. I've called Delta to
purchase a 1-1/4" spindle, but they say I can only put either a 1/2"
or 3/4" spindle on this shaper.
The new 5HP version of this shaper does come with a 1-1/4" spindle,
and from what I've been able to tell from the manuals and parts lists,
the old one and the current models are basically the same machine. So
the only reasons I can think of that I really couldn't use a 1-1/4"
spindle are that the machine doesn't have enough power, or that there
has been some mechanical change--different taper, etc.
Does anyone know for sure what the differences are between the older
shapers and the new version that will take the 1-1/4" spindle? Can I
just buy the larger spindle, or would I also need to replace the
