Tannewitz made these saws with a robust rack and pinion fence
with about a 9” range. In order to cut wider than 9” you have
to re-locate the fence using a series of tapered holes in the
extension table. Without the extension there is only one set of
holes to the left of the blade, severely limiting the fence’s usefulness
in working sheet goods.

My recently acquired 1930s-era Tannewitz JS variety saw came
to me lacking the extension table and a few other parts. I contemplated
giving up and selling the fence to install some sort of modern
aftermarket fence, but many fences would have to be modified
anyway to be compatible with the sliding deck to the left of
the blade.

It occurred to me to weld up some doohickey to drill tapered
pin holes into in order to have some additional fence position,
but then it occurred to me that I could salvage the cast iron
table off a trashed Craftsman table saw I had hauled home
a few weeks ago, thinking I could salvage the arbor in order
to cobble up an improved belt-driven head for my panel saw.

I cut the table off with a cut off wheel on an angle grinder.
The iron wasn’t too difficult to cut with the wheel.

After I cut it off I spent about 20 minutes trying to make
the remaining rough edges look a little better. For some
reason a previous owner of the Craftsman table saw had
made some dramatic modifications, drilling holes and breaking
out part of the hole in the top, perhaps even putting
two saws together like Frankenstein…. it’s quite a bizarre
collection of parts.

Here’s the table propped up in position so I can look at it
and consider how to go about drilling matching holes
so I can bolt it to the Tannewitz with a reasonably flush
joint across the top.

Here’s what the original OEM extension table would look like:

Here’s my replacement table cleaned-up, bolted in position
and the first pair of tapered holes drilled for mounting the
fence.

Here’s a view of the set-up for drilling the middle set of holes:

Nice piece of machinery and clever use of cast off parts.
You attention to detail is to be admired.
I searched your saw brand after your first post and has quite a following.
Interesting subject as usual please post a video with sound of it running.

I’ve ordered a new starter for it. It will be awhile before
it’s ready to use.

I’m actually hoping it will spin a blade quieter than my other
saw, which is pretty loud.
