I'm about  to assemble a big  Roubo  work bench  as per Chris Swarchz's  design.
He  uses no glue  on the  draw  bored tenons.
The top is one piece  24"  wide.

What  do you guys recommend?
 
If the draw bore pegs are made from dry wood they should hold tight for 3 or 4 lifetimes.  If you are a "belt & suspenders" person maybe add some hide glue?  Hide glue has proven to hold for hundred's of years, Titebond isn't quite that old.  [smile]

Or perhaps steel cross dowels:

I made my workbench using this technique and white oak.  I do not think I used any glue - it is a very, very strong joint and the strength comes from the bend in the dowel.  You could add a little glue if you wanted to, but I do not think it is necessary.  The joint actually just ensures the mortise and tenon stays together which you are presumably going to glue.  Hope you will post some pics when it is complete....I would love to see them.

I would use through-drawbores and no glue.  That's what I did on my joinery bench.  The advantage of through and sans-glue is that I can disassemble the bench completely if I ever want/need to.
 
Not quite finished but almost.The shelf boards  have to be added yet  and then a  few coats of Danish oil.
The most impressive  part of this bench is  the vice. The holding power is phenomenal.  And thats without exerting  very much pressure  on the  vice handle.

That looks like the Veritas vice mechanism - I used them when I built my new bench earlier this year. They are well made, operate smoothly and built to last.

Yes its Veritas Peter.

You  seem to have the same mechanism in the Tail  of your bench?  On Axminster  its called  the "Veritas Tail Vice Screw".
No instructions  came with  the package.
Can it be incorporated  in the tail off  the bench?

Axminster also do a Veritas    quick release sliding tail vice  at over £300. I thought a little expensive so I went for the "inset" vice instead.
Thanks  for dropping in on my post.
 
Hi Bob (is it Bob?)

The bench build appeared in consecutive months in 'The Woodworker' magazine, Summer and July 2012. If you subscribe you can look back though all the archive. My article described how to make the tail vice in some detail. You are right, there were no instructions but once I gave it some thought it was actually quite an easy task. I have attached a photo of the underside of the tail vice sub-frame during construction.

Looks very nice. Very solid looking.
What kind of wood is that?

Yellow  pine  and ash for the sliding deadman  and vice front and mahogony  on the vice front base  guide.
The crochet  is a ply of walnut  and oak.

I'll have a look  at  your bench later Peter. Looks  good.
