You can clamp most things as suggested here, but whether it's worth it or not is another matter. If it's pinned, it won't move. If it moved somehow while the glue was setting, unlikely though that is unless it gets physically knocked, then you'd have a bigger problem than a few tiny holes. Particularly with an open grained timber like oak, as long as you use a small nail punch carefully, and fill the hole with the right coloured wax, you really won't see it. Honestly I've filled small holes in oak in the past, and not been able to find them easily myself after. It's all a matter of what level of detail is seen. When you're doing things you can drive yourself mad with detail which no-one else would see.
Tell me about it, we are doing every aspect of the house. I reckon its taking me twice as long with the details but hopefully it'll be worth it in the end. My Mrs just shakes her head and says you won't notice anyway.
The details are what takes the time. I used to make (although I say it myself) very good quality, mostly "one off" pieces of wooden furniture. They all involved a lot of hand work. Furniture, especially things like drawers which can be taken out and examined get looked at fairly closely by the client, and any glaring faults would quickly be seen. Furniture making is a fairly nit picking, and an almost claustrophobic thing to do, and it's easy to let yourself get dragged into seeing every "fault" which no client would see, and which really doesn't matter. The trick, with any job or trade is knowing what matters and what doesn't. What will actually be seen, and what will never be noticed. I'm not talking about bodging things up incidentally, just placing a sensible and achievable limit on quality.
