The Right Amount of Glue
With a little experience, you'll develop a feel for how much glue is just enough. Too little glue creates a “starved joint,” which will be weak. Too much glue makes a mess and wastes glue. With practice, you'll know just how much to apply. You should see a continuous line of small glue beads. When this perfect glue joint sets a little, you'll find it easy to scrape off the jelled excess, and you'll have very little cleanup to do.
Mustard Bottle for Glue
I no longer put up with the messy “over-designed” carpenter’s glue dispensers. Instead, I use old mustard bottles; they don’t clog and they easily reseal between uses. — Richard Painter
