WT322 – It’s My Matt in a Box

Today’s show is sponsored by our lovely, funny, intelligent, and super sexy Patrons

On today’s show, we’re talking about choosing joinery, sanding small pieces without rounding them over, hand planing crowns, and glueing up joints.

What’s On the Bench

  • Marc is making boxes
  • Matt went to IWF
  • Shannon is gluing up a 30″ wide Sapele panel

What’s New


  • Adrian is concerned about using Tried & True oil on his rocker and wants Marc’s impression of the finish.
  • Joe schools us on relative humidity and wood movement
  • Jack spoke with a trauma department head who says there are more bandsaw finger amputations than table saws.


  • Bill wants to know how we choose our joinery.
  • Michael keeps rounding small parts over when sanding and needs help.
  • Erin keeps planing a crown in the edge of his boards with his Jack plane.


  • John wants to know if we put glue on all the surfaces of a joint instead of just the long grain surfaces.

I definitely need to plan for wood movement. My summer indoor air is 70F, 60%RH+ (or 11% EMC). My winter indoor air is 70F, as low as 20%RH (or 4.5% EMC). That is with HVAC running year round and a whole house humdifier. Here in chicago we have very humid summers and cold winters, with forced air the dominant type of heating.

A 12″ wide flatsawn cherry board will shrink ~.25″ under such conditions. Yes, this is something I need to think about when building furniture.

I recently discovered that there are now hard and extra soft plattens available for the Bosch ROS 10/20 sander. I found them on Amazon for about 16$ each. 3M also makes a foam interface pad that seems like it will be great for sculpted forms.

Maybe you guys could discuss cases where harder or softer plattens would be better

Bosch RS035 5-Inch Hard Hook-and-Loop Backing Pad for Ros10/20Vs-Series
Bosch RS033 5-Inch Extra-Soft Hook and Loop Backing Pad for Ros10/20Vs-Series
3M Clean Sanding Soft Interface Disc Pad 28321, Hook and Loop, 5″ Diameter x 0.50″ Thick

Two weeks ago you guys were talking about working with pressure treated wood; One thing that I learned the hard way: if you are cutting wet pressure treated lumber on your Saw Stop; the wet lumber will activate the brake. It was an expensive education. The next time I am working with wet pressure treated lumber I will turn on the bypass mode.

I have watched every video I can find about the Shaper Origin. I can imagine using it in many ways. Hope to do inlay without the expensive template. I ordered one using someone’s code which gave me $100 off. If you order using my code you will give the discount and I will get credit. https://preorder.shapertools.com/ref/EDR0TKKHF

Thanks for the great show.

To the caller who asked about choosing joinery, just get Tage Frid Teaches Woodworking. It is a classic text with a whole section containing detailed information about most standard and some exotic joinery methods with diagrams and methods for each. I use it all the time to choose which joint would work best in a project.

Shannon what do you think of paul sellers technique of starting a #4 plane at the front end of the edge of a broad. How would this technique apply to jouinting?
