I’m new to woodworking, so if this question’s already been covered before just let me know; otherwise, any help would be appreciated. Maybe some of you on the board have some tips on what I can do to improve my glues-ups.
I’ve been building a Holtzapffel workbench after being inspired by Christopher Schwarz’s Holtzapffel, and this week I’m in the process of laminating the top of the bench, but it seems no matter how much I joint/plane I still end up with hairline gaps in some of the laminations. It’s been very frustrating.
Here’s some of the details of my process:
After preparing the stock on a power jointer and planer, I try to fine tune the sticks as best I can with a jack plane and jointer plane.
At this point I dry fit the boards and usually there’s very few to no gaps. I’m using 8 Bessey 24” clamps staggered along the 6 foot length of 3 1 3/4” maple sticks to clamp up these subassemblies. I’ve been using the Titebond III glue, and I apply the glue to both surfaces and roll it on with a sponge roller prior to glue-up. I’ve been allowing at least 5 hours. Also, there’s plenty of squeeze out on both sides.
After removing the clamps and cleaning the assemblies up on the jointer, I have hairline cracks that have been very disappointing – maybe I’m expecting too much, but it seems by looking at other people’s work I can do better. I’m attaching a link to show you what I mean. These are 2 assemblies after cleaning up on the jointer:
Any suggestions on what I can do to improve?
