10E Long or Short Base?

[e2512]

I'm now in a rush to get my 10E, serial number 2512, restored. I noticed tonight that it has the shorter base with it. I'm thinking that with a serial number that low it should have the longer base.

Does anyone have a Model E with a close serial number that can confirm this?

Thanks, Tom

What do you mean by 'shorter' base? The hinge end had two different 'shapes' and the headrest had both two hole and 4 hole versions as well as both CI and aluminum. My 10E has the CI 4 hole headrest. I do not think the hinge end had a different mounting hole spacing, but mine has a round outer shape.

I would expect yours to also have the CI 4 hole headrest and the same hinge end. My SN is 3779.

I didn't explain that very well.

By "Base" I mean the end that flips, not the headrest.

Mine has the more "squared off" base. Making it a few inches shorter than the "Rounder" base. I think it should have the more "Rounded" longer base.

Do you agree?

Tom, over 60+ years, the base may have been changed.

But, if my memory (why can I buy decent memory for a
few dollars, but not "my" memory) serves me, the E model was the
"round" base was an earlier adaption. The more "squared off" base was
a later feature. Skip (at the ER group) would know, for sure.

AIUI the 'squared' off base came later, so yes I agree.

I agree a 10E would have originally had the longer base.
I have two 10ERs, one has the longer rounded pivot base and the other has the squared off pivot base.
Below is a list of 10E/ER design changes compiled by Skip Campbell and posted on the Yahoo Shopsmith 10ER Users forum.
It shows the change to the shorter squared off pivot base didn't happen til1951

The following data was mined from the 10E and 10ER owners manuals.
This may help you determine the age of your machine. Bare in mind
that all of these machines are near 60 year or older. There is
always the possibility that a lost or broken part has been replaced
and possibly with one from a later or earlier machine. Comparing
with other machines in the survey data may help determine if that
is the case.
