I have a few newbie questions regarding the Lamello Dosicol glue applicator as used with biscuit joinery.
I read about it in Anthony Guidice's book: Quick & Easy Custom Cabinets. (A great reference BTW.)
He gives this work aid a high recommendation. I've used it to build a few projects and it does make quick work of spreading the glue around. (Naturally after I bought it I found other much less expensive glue applicators that supposedly work "just as good" but hey, I've got it, I'm going to use it.)
Here's my questions:
So just how much glue are you supposed to put in your biscuit slots?
Nobody ever talks about that. You don't want so much glue in the slot that it oozes out but how much is enough? The Dosicol has an adjustment ring in the base of the unit. I fiddle with it but I'm never really sure if I'm putting the "right" amount of glue in a #20 slot. I only want to depress the applicator one time per slot.
I haven't had any projects come apart. The joints seem plenty strong but I sort of wonder about such things from time to time.
Maybe the slot doesn't really need an "exactly the right amount" of glue in order to be a full strength joint?
I also get different reports on whether or not put also put glue, via brush or dip method, on to the biscuit itself. (This would be in addition to the glue you put in each side of the joint. This is the method that Anthony Guidice recommends.) I've read/seen other via videotapes that don't put the extra glue on the biscuit.
What do you think?
If you had a complex assembly, can you do a sectional glue up? (I haven't experimented with this yet. I was sort of thinking that if you applied glue to one side of the joint it would swell the biscuit up so much you wouldn't be able to get the other half of the joint together.)
Thanks for your help.
