Hi Charlie

I lost you there, you are using t-nuts ???, seems like the wrong
hardware for that application.

Well if you recess them - and then gorilla glue around the outside
they don't pull out easily. And since I'm not going to have to
really torque things down much they should be fine.


A cross dowel would seem more appropriate, that way you could use
longer threaded rod and a cam clamp would make for a real fast hold
down.

That page shows what I call a barrel nut - a section of steel rod with
a threaded
through hole through its side. If you've used them you know that the
hole
for the barrel bolt must be almost perfectly square to the hole for
the
bolt that is to thread into it. Be off a little and it's trouble in
River City
time. There's also the issue of holding the barrel nut at the right
height
and orientation relative to the bolt that's to thread into it. An
earth
magnet on the end of a dowel helps a lot for positioning and rotating
the barrel nut down in the hole Bottom of the page - last two
illustrations
show a barrel nut application and the magnet on a dowel trick

In addition to all that, because the knob/bolt/cam levered bolt is
down an inch from the top of the bench top, the hole for the barrel
nut would have to be 2 3/4" deep in from the bottom. If I drilled
in from the top of the bench top I'd have a nice holel - filled with
debtris. I don't want to create things that trap crap.

Also a set of this kind of bracket on the bottom end would make that
more secure I think,

These flush mount clips - are a modified french cleat. Problem
with them is that you have to attach the part that goes on the
"lip" with wood screws. Only have 1/4" thick ply for the "lip".
could use a nut and bolt or glue a screwing strip on the back.
But it still leaves the back of the shelf to enclose to keep
debris out, but open to allow debris to be blown out the back.

The problem with the "flush" mount clips is that they aren't
flush - that is to say that the two things being clipped together
won't actually touch each other, leaving a gap - for debris
to get into - something I'm trying to avoid.

Just a thought.

Thanks for the suggestions. Will keep the flush mount clips
in mind for some future project. Might come in handy for
securing the fireplace mantle that's on my to do list.

Got the riser blocks for raising the lathe for underneath
it clearance attached to the bench top and the lathe lag
bolted to them. Glue some 80 grit to the end of the bench
top to increase the grip when the bench sides are pulled
into them with the nuts and all thread - and then it's "final"
assembly time. I've got black and english walnut, apricot
and almond ready to rough to round and all the tools are
sharp and ready to go. Anxious to try the 1 1/4" skew.

And now that I found and removed the plastic cup stuck
in the blast gate of the dust collector drop next to
Das Lathe Bench, clean up should be a breeze.

Have fun and take care

Ditto.
