The Holtzapffel Workbench – Day 2

(Part 2 of a series)

When I loaded up the boards to be stickered, I neglected to get a reading right then and there. I took a reading On day two AM and PM. It’s interesting what I found, basically because I’ve only ever played around with the meter. I have no idea what I’m looking for.

I’m using the meter this way for all measurements: insert all the way on the end grain, let sit until reading stops moving under the wood setting (versus construction material). The wood is stickered with various wood, jatoba, purpleheart, maple and fir 2×4. I don’t know if I’m looking for a specific number, or to see if they equalize about the same number. I guess the latter.

Rather than post the numbers for every single board, I thought I’d give a range. 11.0 was the lowest, 16.6 was the highest. This was the morning readings. The afternoon readings ranged from 10.2 to 16.1. I found the jumps interesting, especially the downward trend of the lower ones. I took readings of 2x4s I’ve had in the shop for ages, and they were consistently low to mid 13%. I suppose that is the number I am aiming for.

The 10′ board is showing curvature, I might have to return it considering I was thinking of using it for the long stretchers. Shouldn’t be a huge deal, but it’s a nice clear board.
