« Part 2: Drilling holes for bolts and all-threads Part 3 of Southern Yellow Pine Work Surface (workbench) series Part 4: Glue Curing Box »

This is the first two boards glued together the night before this picture. I have taken the bolts out and everything looks solid. Time will tell. This first one was probably the worst for glue coverage as I was in a hurry – it has been too long since I glued boards together. I keep thinking that if I didn’t hurry, the glue would set up and I’d have to do everything over again. But I think it will still be OK. I used plenty of glue on both sides and the only part I’m really only slightly concerned about is the end corners – I don’t remember if I spread the glue all the way out.

This Yellow Pine is beautiful!

Here is my glue up area. I had some old closet doors to use as a flat work area – they are hollow and light, but fairly flat and easy to clean up the glue because they are painted. I got wise and started using a cheap plastic putty knife to spread the glue out more evenly.

Glue is running out, so that’s a good sign!

Now all five pairs have been glued up.

So the first pair from the day before and the second pair from early morning get glued together at the very last of the day before going into the house.

And here is a quad glued up- the camera amplifies the difference in height of the laminations – this end curled a bit on one side before the glue-up.

More later.

I dont believe you need to rush that much with the yellow glue. I usually glue three at a time, all 6,7 or 8 ft long. Then glue them up in pairs and pairs into slabs. Works well and if you spred the glue even and on both pieces and dont try to mash them when clamping, you will have great bench tops, just remember your 7 Ps, pryier proper planing prevents piss poor proformance. Sorry for the bad word here, just the facts..

Thank you benchbuilder. I just saw your comment today. I am getting more at ease with the gluing now. I have 14 boards glued together now and it is 21” wide. I still need to get someone to help me bring it down from my 2nd story apartment into the garage. It got so cold recently that I brought the pairs of boards up inside where it’s warm to glue them together. I didn’t do anything to the surfaces of these when I glued them up. The glue seems like it will hold very well even though each board wasn’t “perfect” – some had a few mill marks, some had a few voids where knots were, etc. I have read that the wood glue works best when the two surfaces being joined are nearly perfectly flat against one another and a lot of pressure is applied. Some technical advice includes XX lbs per sq in for different species of wood. I don’t get that technical with anything I do. I haven’t conducted any tests on the strength of the glued joints that I have done either. I have made one “coffee” table that was just wood and glue – it’s about 10 years or more old and holds together just fine – I didn’t prep any edges with that one either – it’s white pine. I did use some dowels though on the top – three 2 X 6’s at 48” long. I am going to use glue and dowels on the rest of my bench too (I usually use bolts and other hardware in addition to glue when putting things together, but I now know that glue will hold it together alone if designed a certain way.) I had thought about gluing up beams and slabs and then chopping out a bunch of dovetails and mortise/tenons, but that seemed less efficient than just designing it to fit together like a puzzle – after all the boards start out as 2 bys and if you cut them right and fit them together right, they make their own mortise & tenons. I’ll post more pictures as I go along. It’s still too cold out to do very much gluing.
