Hey y’all! I’m new to the LJ forum and wanted to ask my first question. I’ve been piddling with woodworking for 2 years. No serious projects. My crazier half has wanted a vanity for our bedroom for ages but I never really found one that I liked. So I designed a floating vanity. Used 2×4 36” for the mount, then 2x4 10.5” for support arms, 1X12 ripped for the trim work. I attached the support arms of it using pocket holes and Tite Bond 2. When I went to take my last measurements before ripping down that 1X, I noticed that the arms were off by 1/4” at the ends, across the span; 35 3/4”.
Not a big problem, I was able to rip some shims and got it all knocked out. But it still took a jab at my confidence. 1/4” is quite a variance. All my cuts were square and on the bugs nuts.
So did I foul up when I used my pocket holes? I don’t get it.
Any advice is appreciated.

Thanks for your time,

Jason

I’m going to guess the 2×4 was cut on the wrong side of your 36” mark, taking 1/8” with each cut for the overall total of 1/4”.

Just a guess.

Second guess is you cut right through the line, vs. alongside it.

Make sure cut lines have an additional mark alongside, showing where the kerf of the sawblade is to remove material.

Was the problem the board mounted to the wall was not level?

Keep practicing… Everyone starts crappy and gets better.

Pay a bit more attention to what you’re measuring, where you’re marking, and where you’re cutting.

The “line” is a lot smaller than a saw blade, so think about measuring and cutting at the edge of the line. And make sure you know which edge (and mark it!).

A line has two sides, a “good” side and a waste side. Always cut on waste side because if you don’t errors will accumulate. Like Smitty says it takes only 2 cuts with an 1/8” saw blade to equal 1/4”.

Thanks guys for the replies. I usually do a good job at cutting my material properly but do get into the bad habit of not paying attention to the line, which is work vs waste. And the mount was level. I checked the level at all steps of assembly.
If you were somehow behind the wall, imagine the support arms bowing in at an angle. That’s how I was off 1/4 of an inch. I’m starting to think that what happened is that I attached one of the arms with the pocket holes facing inward and the other outward. Maybe that had something to do with it? I’m half tempted to rip the trim off for further inspection but I think she would kill me.

It’s not the mistake, it’s how you recover and adjust to fix it. Your project looks great. You made adjustments and recovered well. I have been off a quarter inch or more on many projects. Welcome to woodworking. Several good “could be” suggestions here…......

Like other’s said we all been there. By the way, there are no “MISTAKES” , just design changes. Remember the motto, if you can’t hide it, accentuate it! I’d put some molding around it and made it stand out.

...one more, the old “measure twice cut once works”.

Also, a story stick helps and does wonders for your accuracy.

Cheers and have fun and don’t sweat the small stuff.

If I understand the issue correctly, I’m wondering if the 2×4 supports were perfectly straight? Or did one have a slight bow in it? or were the ends that attached the wall not exactly 90 degrees?

Know what? The best on this site have been there. That’s why some have tag lines about being able to hide their experiences.

Heck, more than forty years in, I’ve had some pretty fancy firewood.

It was not a mistake, it was a educational moment. Now don’t that sound better?

I have found when making things for the wife she will over look any mistakes if I leave a small piece of jewelry, say gold, diamond and she just loves my work!;)
