That's a good question Antonio and I have to admit I don't have a good answer:>/
With TB cold press or TB1 or 3 for that matter I generally leave them in the bag for 2 - 3 hours. Not sure if it's totally necessary, but I don't know how the vacuum affects the drying time of the glue? So I err on the side of longer clamp times. I do know that stuff seems pretty well set after 2 hours, though I usually wait until the next day before I do any milling. Without a press I don't see why it would be any different than a regular glue up....like say a door? I leave normal glue-ups in the clamps for 20 - 30 minutes then unclamp, scrape any glue, stack them up and do the next batch!
Of course if its curved work that's a different story! I'll leave that overnight just to be safe;>)
Now most of this is completely moot as your using a different glue which I have no experience with whatsoever. Therefore you need to look into how long your glue needs to be clamped up;>)
FWIW a vac press is one of those tools you'll wonder how you did without once you use one! They're a bit spendy to buy new, but if you do some homework and understand the way they work, you can cobble together a high quality press for about half of what a new one costs;>)
good luck,
